Hemodynamic changes in the prone position according to fluid loading after anaesthesia induction in patients undergoing lumbar spine surgery: a randomized, assessor-blind, prospective study. Ann Med 2024; 56:2356645. [PMID: 38794845 PMCID: PMC11133492 DOI: 10.1080/07853890.2024.2356645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 04/28/2024] [Indexed: 05/26/2024] Open
Abstract
INTRODUCTION A change from the supine to prone position causes hemodynamic alterations. We aimed to evaluate the effect of fluid preloading in the supine position, the subsequent hemodynamic changes in the prone position and postoperative outcomes. PATIENTS AND METHODS This prospective, assessor-blind, randomized controlled trial was conducted between March and June 2023. Adults scheduled for elective orthopaedic lumbar surgery under general anaesthesia were enrolled. In total, 80 participants were randomly assigned to fluid maintenance (M) or loading (L) groups. Both groups were administered intravenous fluid at a rate of 2 ml/kg/h until surgical incision; Group L was loaded with an additional 5 ml/kg intravenous fluid for 10 min after anaesthesia induction. The primary outcome was incidence of hypotension before surgical incision. Secondary outcomes included differences in the mean blood pressure (mBP), heart rate, pleth variability index (PVi), stroke volume variation (SVV), pulse pressure variation (PPV), stroke volume index and cardiac index before surgical incision between the two groups. Additionally, postoperative complications until postoperative day 2 and postoperative hospital length of stay were investigated. RESULTS Hypotension was prevalent in Group M before surgical incision and could be predicted by a baseline PVi >16. The mBP was significantly higher in Group L immediately after fluid loading. The PVi, SVV and PPV were lower in Group L after fluid loading, with continued differences at 2-3 time points for SVV and PPV. Other outcomes did not differ between the two groups. CONCLUSION Fluid loading after inducing general anaesthesia could reduce the occurrence of hypotension until surgical incision in patients scheduled for surgery in the prone position. Additionally, hypotension could be predicted in patients with a baseline PVi >16. Therefore, intravenous fluid loading is strongly recommended in patients with high baseline PVi to prevent hypotension after anaesthesia induction and in the prone position. TRIAL NUMBER KCT0008294 (date of registration: 16 March 2023).

Abstract
Drugs that act on α-adrenoceptors may contain morpholine and pyrimidinone heterocycles. The aim of this study was to synthesize a series of pyrimidinones (S6a-e and S8) and characterize their α-adrenoceptor activity. Cytotoxicity assays (MTT and LDH) were performed in A7r5 and HUVECs. Concentration-effect curves to phenylephrine (Phe) were performed in rat aortic rings in the presence of compounds S6a-e and S8 or vehicle. Nitric oxide (NO) production and NO stable metabolic products, nitrite and nitrate, expressed as total nitrogen oxides (NOx) were assessed in HUVECs by confocal microscopy with the DAF-2DA probe and by the Griess reaction, respectively. Molecular docking simulations were performed using the 6a compound and α2A-adrenoceptor. In the evaluated conditions, the percentage of viable cells and the release of LDH were similar between control cells and cells exposed to the tested pyrimidinones. S6d, S6e, S8, and the positive control prazosin (but not S6a, S6b, and S6c) decreased Phe-induced contractions in endothelium-denuded aortic rings. S6a, S6b, and S6c decreased Phe-induced contractions in endothelium-intact aortic rings. The effect of S6a was abolished by L-NAME. NO production and NOx levels were inhibited in the presence of the α2 receptor antagonist yohimbine and the NOS inhibitor L-NAME. The 6a docking simulation estimated that the mean binding free energy of the compound was lower than the estimated value for yohimbine. These data suggest that S6d, S6e, and S8 may be α1-adrenoceptor antagonists while S6a acts as an agonist of α2-adrenoceptors.

The effect of a local anesthetic cocktail in a serratus anterior plane and PECS 1 block for implant-based breast reconstruction. JPRAS Open 2024; 41:116-127. [PMID: 38984322 PMCID: PMC11231500 DOI: 10.1016/j.jpra.2024.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 04/25/2024] [Indexed: 07/11/2024] Open
Abstract
Introduction Enhanced recovery after surgery (ERAS) protocols have been implemented to decrease opioid use and decrease patient hospital length of stay (LOS, days). Serratus anterior plane (SAP) blocks anesthetize the T2 through T9 dermatomes of the breast and can be applied intraoperatively. The purpose of this study was to compare postoperative opioid (OME) consumption and LOS between a control group, an ERAS group, and an ERAS/local anesthetic cocktail group in patients who underwent implant-based breast reconstruction. Methods In this study, 142 women who underwent implant-based breast reconstruction between 2004 and 2020 were divided into Group A (46 patients), a historical cohort; Group B (73 patients), an ERAS/no-block control group; and Group C (23 patients), an ERAS/anesthetic cocktail study group. Primary outcomes of interest were postanesthesia care unit (PACU), inpatient and total hospital OME consumption, and PACU LOS. Results A significant decrease was observed from Group A to C in PACU LOS (103.3 vs. 80.2 vs. 70.5; p = 0.011), OME use (25.1 vs. 11.4 vs. 5.7; p < 0.0001), and total hospital OME (120.3 vs. 95.2 vs. 35.9; p < 0.05). No difference was observed in inpatient OMEs between the three groups (95.2 vs. 83.8 vs. 30.8; p = 0.212). Despite not reaching statistical significance, Group C consumed an average of 50-60 % less opioids per patient than did Group B in PACU, inpatient, and total hospital OMEs. Conclusion Local anesthetic blocks are important components of ERAS protocols. Our results demonstrate that a combination regional block with a local anesthetic cocktail in an ERAS protocol can decrease opioid consumption in implant-based breast reconstruction.

Abstract
Periodic fever syndromes are autoinflammatory disorders associated with recurrent fevers unrelated to infection. Little is known about the perioperative management of patients with these syndromes, and existing literature consists primarily of case reports and occasional case series. This narrative review discusses background information and diagnostic criteria for the three most common periodic fever syndromes: periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA), familial Mediterranean fever (FMF), and TNF receptor-associated periodic syndrome (TRAPS), and describes perioperative considerations for anesthesia providers when caring for the patient with a periodic fever syndrome. We include a systems-based framework in which to organize these considerations.

Abstract
PURPOSE OF REVIEW The healthcare sector has a substantial environmental footprint, and the delivery of anesthesia contributes significantly. Inhaled anesthetics themselves are potent greenhouse gases, unused intravenous medication exert toxic effects on the environment, and the increasing reliance on single-use devices has led to an ever-growing amount of solid waste produced in operating rooms. This review discusses many of these environmental impacts and suggests practices to mitigate the environmental footprint of anesthetic practice. RECENT FINDINGS The choice of anesthesia maintenance has significant environmental implications, with nitrous oxide and desflurane having the highest carbon footprint of all anesthetic agents. Using low fresh gas flows and supplementing or replacing inhalational agents with propofol leads to a significant reduction in emissions. Many intravenous anesthetic agents pose a risk of environmental toxicity, and efforts should be made to decrease medication waste and ensure appropriate disposal of unused medications to minimize their environmental impacts. Additionally, consideration should be given to replacing single-use devices in the operating rooms with reusable alternatives that are often both environmentally and economically superior. And solid waste generated in the operating room should be segregated thoughtfully, as processing regulated medical waste is a highly energy-intensive process. SUMMARY Significant opportunities exist to improve the environmental footprint of anesthesia practice, and with the rapidly worsening climate crisis, the importance of implementing changes is greater than ever.

Med Gas Res 2024; 14:108-114.

Abstract
Although low-flow anesthesia is widely used due to its various advantages, there are concerns about potential and relative hypoxia. Furthermore, oxygen is also a drug with benefits and adverse effects. We aimed to evaluate and compare the effect of real-time oxygen consumption versus fixed flow-based low flow anesthesia on oxygenation and perfusion and to compare the economic benefits. With ethical approvals and informed consent, participants were randomly assigned to a dynamic group (13 males, and 27 females) receiving fresh gas flows depending on real-time oxygen consumption (dynamic O2: N2O), and a fixed group (20 males, and 13 females) receiving fixed fresh gas flows of 600 mL/min (with O2: N2O of 1:1). Oxygen partial pressure and serum lactate were comparable between groups. However, isoflurane consumed and costs incurred were significantly different. Total oxygen consumption per minute was also significantly lower in the dynamic group than the fixed group. No episodes of hypoxia were observed in either group. Real-time oxygen consumption-based low flow anesthesia is feasible and cost-effective without affecting the patient's global perfusion and outcome.

Abstract
Introduction The present study was conducted to compare the effects of clonidine and tranexamic acid on the volume of bleeding and quality of the surgical field in terms of bleeding in candidates who underwent rhinoplasty. Methods In this two-sided clinical trial, candidates eligible for rhinoplasty were randomly assigned to two treatment groups: tranexamic acid and clonidine. The first group received tranexamic acid at a dose of 700 µg/kg of body weight 2 hours before the surgical procedure, whereas the second group received clonidine orally at a dose of 2 mg/kg of body weight, 90 minutes before surgery. Subsequently, the volume of bleeding was calculated based on the amount of blood collected via suction and in blood-soaked gauze, which was previously weighed. Results Among the 92 patients who underwent rhinoplasty, 82% were women. The mean age and standard deviation (SD) of individuals who underwent rhinoplasty were 29.22 ± 8.50 years. There were no significant differences between the two treatment groups in terms of age, gender, and body mass index. The volume of blood collected via suction during rhinoplasty, categorized into surgery duration <63 minutes and ≤63 minutes, showed a significant difference between the 2 treatment groups. Conclusion The use of tranexamic acid, compared with clonidine, resulted in lesser intraoperative bleeding and better surgical field quality. Considering the superior effectiveness of tranexamic acid in reducing intraoperative bleeding, it is recommended to use tranexamic acid instead of clonidine in rhinoplasty.

Abstract
This review aims to assess the published evidence on airway management with a supraglottic airway device (SGA) for general anaesthesia in patients requiring a caesarean section. Physiological changes during pregnancy can make airway management in parturients challenging. At the same time, pregnant patients are at risk of pulmonary aspiration due to hormonal and mechanical alterations. The standard airway management for parturients undergoing caesarean section is rapid sequence induction followed by tracheal intubation. Evidence exists that using second-generation SGA devices is well tolerated and effective in selected patients. In this review, we provide an overview of the existing evidence and provide an algorithm to make an evidence-based clinical decision on the use of SGA devices. An online literature search was performed in Medline, Embase, PubMed, Emcare, Cochrane Library and CINAHL. The search terms used were 'supraglottic airway', 'supraglottic airway device', 'supraglottic airway management', 'supraglottic tube', 'i-gel', laryngeal mask', 'laryngeal mask airway', 'LMA', 'SGA', 'Proseal', 'Supreme', 'obstetric surgery', 'obstetric operation', 'general anaesthesia', 'caesarean' or 'caesarean section', 'abdominal delivery'. Full-text articles in English, Dutch and French were included. Case reports and studies in which the surgery was not a caesarean section were excluded. The initial search yielded 815 results. Following screening, deduplication and removal of publications that were unrelated to the topic or did not fit the inclusion criteria, 13 manuscripts were included in our analysis. A total of 7722 patients were described in the articles included. In the majority of manuscripts, second-generation SGA devices were used. There were seven cases of failed insertion and a need for conversion to tracheal intubation; first-generation SGA devices were used in these cases. There were no cases of pulmonary aspiration, and only one case of gastric regurgitation was described. Growing evidence suggests that the use of second-generation SGA devices might be well tolerated as the primary method for securing the airway for caesarean sections requiring general anaesthesia, in selected patients with a low risk for aspiration and difficult intubation.

Abstract
BACKGROUND AND OBJECTIVES The preferred osmotic agent used for brain relaxation during craniotomies remains unclear, either mannitol (MAN) or hypertonic saline (HTS). Hence, we sought to compare these solutions in this population. METHODS MEDLINE, Embase, and Cochrane databases were systematically searched until August 02, 2023. Data were examined using the Mantel-Haenszel method and 95% CIs. Heterogeneity was assessed using I2 statistics. Meta-regression analysis was conducted to evaluate a possible link between Brain Relaxation Score and tumor volume. R, version 4.2.3, was used for statistical analysis. RESULTS A total of 16 randomized controlled trials and 1031 patients were included, of whom 631 (61%) underwent surgery for supratentorial tumor resection. Compared with MAN, HTS achieved better rates of brain relaxation (80% vs 71%; odds ratio [OR] 1.68; 95% CI 1.22-2.33; P = .001; I2 = 0%), which was also demonstrated in the subgroup analysis of patients with supratentorial brain tumor (78% vs 65%; OR 2.02; 95% CI 1.36-2.99; P = .0005; I2 = 0%); a minor number of patients requiring a second dose of osmotic agent (14% vs 28%; OR 0.43; 95% CI 0.27-0.69; P = .0003; I2 = 0%); a lower fluid intake (mean difference -475.9341 mL; 95% CI -818.8952 to -132.9730; P = .007; I2 = 88%); and lower urine output (mean difference -462.0941 mL; 95% CI -585.3020 to -338.8862; P = <.001; I2 = 96%). Hospital length of stay and focal neurological deficits did not reach a statistically significant difference between groups. CONCLUSION In this updated meta-analysis, consistent results suggest that HTS is associated with more beneficial outcomes than MAN in patients undergoing craniotomy.

OBJECTIVE The objective of this prospective study was to measure the level of pain and anxiety before, during, and after an oral biopsy, and fear memory 7 days following the procedure. STUDY DESIGN This was a single-center, prospective, survey-based observational pilot study of patients seen from April 2022 to June 2023 at the Sol Silverman Oral Medicine Clinic, at the University of California San Francisco (UCSF). We assessed the level of pain and anxiety before, during, and after oral biopsies and a fear memory interview on the 7th day post oral biopsy. RESULTS Sixty patients participated in the study (median age: 56.5 years (range: 20-95 years); 65% females). Most patients had a punch oral biopsy (84%). The median score for pain was 2 (range 0-9) on day 1 post biopsy and 0 (range 0-4) on day 7 post biopsy (p < .0001); the median score for anxiety was 0 (range 0-3) on day 1 post biopsy and 0 (range 0-2) on day 7 post biopsy. During the phone interview on day 7, patients reported a median score of 1 for pain (range: 0-8), unpleasantness (range 0-9) and anxiety/fear (range 0-10). CONCLUSIONS Oral biopsy is a well-tolerated procedure with minimal pain and anxiety/fear.

A comparative study of the dorsolateral prefrontal cortex targeting approaches for transcranial magnetic stimulation treatment: Insights from the healthy control data. Brain Res 2024; 1838:148989. [PMID: 38723740 DOI: 10.1016/j.brainres.2024.148989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 05/05/2024] [Accepted: 05/06/2024] [Indexed: 05/13/2024]
Abstract
Repetitive transcranial magnetic stimulation (rTMS) to the left dorsolateral prefrontal cortex (DLPFC) is an established treatment for medication-resistant depression. Several targeting methods for the left DLPFC have been proposed including identification with resting-state functional magnetic resonance imaging (rs-fMRI) neuronavigation, stimulus coordinates based on structural MRI, or electroencephalography (EEG) F3 site by Beam F3 method. To date, neuroanatomical and neurofunctional differences among those approaches have not been investigated on healthy subjects, which are structurally and functionally unaffected by psychiatric disorders. This study aimed to compare the mean location, its dispersion, and its functional connectivity with the subgenual cingulate cortex (SGC), which is known to be associated with the therapeutic outcome in depression, of various approaches to target the DLPFC in healthy subjects. Fifty-seven healthy subjects underwent MRI scans to identify the stimulation site based on their resting-state functional connectivity and were measured their head size for targeting with Beam F3 method. In addition, we included two fixed stimulus coordinates over the DLPFC in the analysis, as recommended in previous studies. From the results, the rs-fMRI method had, as expected, more dispersed target sites across subjects and the greatest anticorrelation with the SGC, reflecting the known fact that personalized neuronavigation yields the greatest antidepressant effect. In contrast, the targets located by the other methods were relatively close together with less dispersion, and did not differ in anticorrelation with the SGC, implying their limitation of the therapeutic efficacy and possible interchangeability of them.

Abstract
BACKGROUND Pediatric patients often require sedation during magnetic resonance imaging (MRI) and computed tomography (CT) to ensure stillness and minimize stress. This meta-analysis compared the effectiveness and safety of 3 sedative agents-dexmedetomidine, midazolam, and chloral hydrate-for pediatric MRI/CT sedation. METHODS Six studies with a total of 633 patients were included in the analysis. Quality assessment revealed varying levels of bias risk. Dexmedetomidine exhibited a significantly higher successful sedation rate compared to midazolam (risk ratio [RR] = 0.43, 95% confidence interval [CI] [0.29-0.64]), but no statistically significant difference compared to chloral hydrate (RR = 0.94, 95% CI [0.60-1.45]). Chloral hydrate also showed a higher successful sedation rate compared to midazolam (RR = 0.46, 95% CI [0.25-0.83]). The onset of sedation time did not significantly differ between the 3 agents. RESULTS The dexmedetomidine group had a significantly higher incidence of bradycardia compared to the chloral hydrate group (RR = 0.17, 95% CI [0.05-0.59]), but no significant difference compared to the midazolam group (RR = 0.29, 95% CI [0.06-1.26]). No statistically significant differences were observed in the incidence of nausea and vomiting between the 3 groups. CONCLUSIONS Dexmedetomidine demonstrates effectiveness in pediatric MRI/CT sedation, offering advantages over midazolam and similar efficacy to chloral hydrate. Careful cardiovascular monitoring is essential during administration, particularly in patients with congenital heart disease. Sublingual and intranasal administration of dexmedetomidine is a viable option with high bioavailability. This meta-analysis contributes valuable insights into refining sedation protocols for pediatric imaging procedures, emphasizing efficacy and safety considerations.

Abstract
BACKGROUND Dexamethasone is associated with increased blood glucose levels that could impact patient outcomes or management. This study aimed to synthesize the available evidence regarding the impact of an intraoperative single dose of dexamethasone on blood glucose levels. METHODS We searched CENTRAL, MEDLINE, and clinicaltrials.gov for randomized controlled trials (RCTs) comparing a single intraoperative dose of dexamethasone to control in adult patients who underwent noncardiac surgery. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the review was registered in PROSPERO (CRD42023420562). Data were pooled using a random-effects model. We reported pooled dichotomous data using odds ratios (OR) and continuous data using the mean difference (MD), reporting 95% confidence intervals (95% CIs), and corresponding P-values for both. Confidence in the evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. As primary outcomes we assessed maximum blood glucose levels measurement and variation from baseline within 24 hours of surgery; blood glucose levels measurement and variation from baseline at 2, 4, 8, 12, and 24 hours after dexamethasone administration. As secondary outcomes, we evaluated insulin requirements and hyperglycemic events. RESULTS We included 23 RCTs, enrolling 11,154 participants overall. Dexamethasone was associated with a significant increment in blood glucose levels compared to control at all timepoints. The results showed an increase compared to control of 0.37 mmol L-1 (6.7 mg dL-1) at 2 hours (95% CI, 0.16-0.58 mmol L-1 or 2.9-10.5 mg dL-1), 0.97 mmol L-1 (17.5 mg dL-1) at 4 hours (95% CI, 0.67-1.25 mmol L-1 or 12.1-22.5 mg dL-1), 0.96 mmol L-1 (17.3 mg dL-1) at 8 hours (95% CI, 0.55-1.36 mmol L-1 or 9.9-24.5 mg dL-1), 0.90 mmol L-1 (16.2 mg dL-1) at 12 hours (95% CI, 0.62-1.19 mmol L-1 or 11.2-21.4 mg dL-1) and 0.59 mmol L-1 (10.6 mg dL-1) at 24 hours (95% CI, 0.22-0.96 mmol L-1 or 4.0-17.3 mg dL-1). No difference was found between subgroups regarding diabetic status (patients with diabetes versus patients without diabetes) in all the outcomes except 2 (maximum blood glucose levels variation within 24 hours and variation at 4 hours) and dexamethasone dose (4-5 mg vs 8-10 mg) in all the outcomes except 2 (blood glucose levels at 24 hours and hyperglycemic events). CONCLUSIONS Mean blood glucose levels rise between 0.37 and 1.63 mmol L-1 (6.7 and 29.4 mg dL-1) within 24 hours after a single dose of dexamethasone administered at induction of anesthesia compared to control, but in most patients this difference will not be clinically relevant.

Muzien SJ. Sudden cardiac arrest in low-risk patient during transurethral resection of the prostate under spinal anesthesia: Acute myocardial infraction a possible cause? Case report. Int J Surg Case Rep 2024; 122:110057. [PMID: 39067101 PMCID: PMC11331950 DOI: 10.1016/j.ijscr.2024.110057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2024] [Revised: 07/13/2024] [Accepted: 07/19/2024] [Indexed: 07/30/2024] Open
Abstract
INTRODUCTION AND IMPORTANCY A patient experienced a sudden cardiac arrest (CA) during a transurethral resection of the prostate (TURP) under spinal anesthesia (SA), despite no conventional risk factors. The incident, which occurred during TURP without significant changes in vital signs or electrocardiogram (ECG), this report, contributes to accidents during SA for TURP in healthy patients. PRESENTATION OF CASE A 53-year-old man with BMI 24.1 underwent TURP. SA was administered using bupivacaine 15 mg and fentanyl 10 μg. The patient had normal vital signs & sinus rhythm. However, around a hr. into the procedure, he experienced fatigue, severe chest pain, sweating, & nausea, leading to unconsciousness & CA. The anesthesia and surgical teams initiated cardiopulmonary resuscitation according to American Heart Association guidelines, but CA could not be reversed. CLINICAL DISCUSSION The patient showed symptoms of acute MI while undergoing TURP but didn't exhibit typical changes on ECG. Early detection using a 5‑lead ECG or troponin level may not be possible so make it challenging to get definitive diagnosis of MI to start managements. It's highlighted that some individuals might not meet standard MI diagnostic criteria. CONCLUSION Diagnosing MI using only a 5-lead ECG can be challenging, as some patients may not exhibit MI findings. Modern monitors that numerically display ST segment depression, along with the availability of continuous 12‑lead ECG in the operating theater, can improve emergency detection. In resource-limited countries, adopting new protocols for MI management is crucial. These protocols should include initiating MI treatments even without a confirmed diagnosis.

Abstract
This study aimed to compare the effects of intrathecal dexmedetomidine, fentanyl and magnesium sulfate added to ropivacaine on the onset and duration of sensory and motor blocks in lower abdominal surgery. This double-blind randomized clinical trial included 90 patients scheduled for lower abdominal surgery at Vali-Asr Hospital in Arak, Iran. The enrolled patients were randomly divided into three equal groups and then underwent spinal anesthesia. The first group received 10 μg of dexmedetomidine, the second group received 50 μg of fentanyl, and the third group received 200 mg of 20% magnesium sulfate intrathecally in addition to 15 mg of 0.5% ropivacaine. In the dexmedetomidine group, the mean arterial blood pressure was lower than the other two groups (P = 0.001). Moreover, the time to onset of sensory block (P = 0.001) and the mean duration of sensory block (P = 0.001) were shorter and longer, respectively, in the dexmedetomidine group than in the other two groups. In the dexmedetomidine group, the mean time to onset of motor block (P = 0.001) and the mean duration of motor block (P = 0.001) were lower and higher than in the other two groups, respectively. There was no significant difference in visual analog scale score, heart rate, administered opioid, and drug side effects among the three groups. Dexmedetomidine caused early sensory and motor blocks while prolonging the duration of sensory and motor blocks compared with the other two groups. In addition, dexmedetomidine reduced mean arterial blood pressure in patients. Based on the findings of this study, it is recommended that dexmedetomidine can be used in order to enhance the quality of sensory and motor block in patients.

Abstract
BACKGROUND Sugammadex is a novel agent that reverses neuromuscular blockade during general anesthesia. Recent case reports have raised concerns regarding potential cardiac adverse events (CAEs). However, no large-scale real-world studies have yet evaluated the potential link between sugammadex and CAEs. RESEARCH DESIGN AND METHODS Data from the FDA Adverse Event Reporting System were obtained. The association between sugammadex and CAE was evaluated using reporting odds ratio, proportional reporting ratio, Bayesian confidence propagation neural network, and multi-item gamma Poisson shrinker methods. Serious outcomes resulting from sugammadex-related CAEs were assessed, and complications associated with CAEs were evaluated. RESULTS Nineteen CAEs were identified and classified into two categories: cardiac arrhythmias and coronary artery disorders. The most frequent CAEs were bradycardia (n = 202), cardiac arrest (n = 119), tachycardia (n = 30), and Kounis syndrome (n = 22). Subgroup analysis based on age, sex, and weight revealed parallel findings. The CAEs most likely to result in serious consequences were pulseless electrical activity and cardiac arrest. The most common concurrent adverse effects with CAEs were hypotension (n = 51), anaphylactic reactions (n = 46), and anaphylactic shock (n = 23). CONCLUSION This study suggests a potential link between sugammadex and CAEs, highlighting the need for careful monitoring and personalized risk assessment, especially in patients with cardiovascular risk factors.

Abstract
PURPOSE This study aimed to estimate the median effective dose of intrathecal isobaric ropivacaine without opioid required for adequate cesarean delivery anesthesia after epidural labor analgesia. METHODS Patients aged 20-40 years with American Society of Anesthesiology scores of I-II, body mass index ≤ 36, who underwent emergency cesarean delivery after failed vaginal delivery with epidural analgesia of a duration ≤ 6 h were included in the study. After removal of the epidural used for labor analgesia, a new combined spinal epidural was performed, and a dose of intrathecal isobaric ropivacaine without opioid was administered. The dose was determined using up-down methodology, with the starting patient's dose set to 12 mg. Adequate anesthesia, defined as a pinprick level no lower than T6 at 5 min after ropivacaine administration, resulted in the next patient receiving a dose of ropivacaine 1 mg higher, and inadequate anesthesia 1 mg lower. The primary outcome was the median (95% confidence interval (CI)) dose of spinal ropivacaine required for adequate cesarean delivery anesthesia. RESULTS Of the 46 patients included in the study, 40 were analyzed. The median spinal ropivacaine dose was 8.11 mg (95% CI 7.29-8.93 mg) by the Dixon and Mood method and 8.06 mg (95% CI 6.93-9.00 mg) by isotonic regression. Two patients had high spinal anesthesia. CONCLUSION Our findings suggest that for 50% of patients undergoing cesarean delivery after failed vaginal delivery with epidural analgesia, an 8-mg spinal dose of isobaric ropivacaine without opioid provides an anesthesia level no lower than T6 at 5 min.

Abstract
BACKGROUND AND OBJECTIVES To analyze the ability of prehospital lactate levels to predict 2-day in-hospital mortality in patients with traumatic brain injury (TBI), severe TBI (Glasgow Coma Scale (GCS) ≤ 8 points), and mild or moderate TBI (GCS ≥ 9 points). Second, 90-day mortality was also explored. METHODS This was a prospective, multicenter, emergency medical services (EMSs) delivery, ambulance-based, derivation-validation cohort study developed in 5 tertiary hospitals (Spain), from November 1, 2019, to July 31, 2022. Patients were recruited from among all phone requests for emergency assistance among adults who were later evacuated to referral hospitals with acute TBI. The exclusion criteria were minors, pregnancy, trauma patients without TBI, delayed presentations, patients were discharged in situ, participants with cardiac arrest, and unavailability to obtain a blood sample. The primary outcome was all-cause 2-day in-hospital mortality and 90-day mortality in patients with moderate or mild TBI compared with patients with severe TBI. Clinical and analytical parameters (lactate and glucose) were collected. The discriminative power (area under the receiver operating characteristic curve [AUC]) and calibration curve were calculated for 2 geographically separated cohorts. RESULTS A total of 509 patients were ultimately included. The median age was 58 years (interquartile range: 43-75), and 167 patients were female (32.8%). The primary outcome occurred in 9 (2.2%) of 415 patients with moderate or mild TBI and in 42 (44.7%) of 94 patients with severe TBI. The predictive capacity of the lactate concentration was globally validated in our cohort, for which the AUC was 0.874 (95% CI 0.805-0.942) for the validation cohort. The ability of the GCS score to predict lactate concentration was greater in patients with a GCS score ≥9 points, with an AUC of 0.925 (95% CI 0.808-1.000) and a negative predictive value of 99.09 (95% CI 98.55-99.64) in the validation cohort. CONCLUSION Our results show the benefit of using lactate in all patients with TBI, particularly in those with a GCS ≥9 points. Routine incorporation of lactate in the screening of patients with TBI could presumably reduce mortality and deterioration rates because of quicker and better identification of patients at risk.

Chai D, Jiang H, Lv X. The impact of dexmedetomidine on ketamine-induced neurotoxicity and cognitive impairment in young mice. Int J Dev Neurosci 2024. [PMID: 39192610 DOI: 10.1002/jdn.10373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2024] [Revised: 08/15/2024] [Accepted: 08/16/2024] [Indexed: 08/29/2024] Open
Abstract
BACKGROUND The potential neuroprotective effects of dexmedetomidine against ketamine-induced neurotoxicity remain inconclusive. This study aims to investigate the influence of dexmedetomidine on ketamine-induced neuronal apoptosis and neurodevelopmental toxicity. METHODS In vitro experiments employed concentrations of 0.1 uM for dexmedetomidine and 50 uM for ketamine individually as well as their combination. Changes in apoptotic proteins and dendritic development in neurons were assessed after a 6-h exposure to the drugs with evaluations conducted 24 hs' post-treatment. In vivo experiments entailed intraperitoneal administration starting from postnatal Day 7 (P7) continuously for 3 days (P7-P9) using dosages of 100 mg/kg for ketamine and 1 mg/kg for dexmedetomidine alone or combined. Learning, memory and motor coordination abilities were evaluated via rotary rod tests and shuttle box experiments at P30 and P60, respectively. RESULTS Dexmedetomidine effectively mitigated ketamine-induced apoptosis in hippocampal neurons but did not alleviate associated dendritic developmental abnormalities. Although causing reduced motor coordination in mice, no improvement was observed with regard to this effect or reaction speed when treated with dexmedetomidine alongside ketamine. CONCLUSION This study demonstrates that while dexmedetomidine can mitigate ketamine-induced neuronal apoptosis, it has limited impact on its associated neurodevelopmental toxicities.

Abstract
Objective This study investigates the effect of low-dose dexmedetomidine infusion on perioperative neurocognitive function in elderly patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Patients and Methods This double-blind trial enrolled 80 elderly ERCP patients randomized to receive dexmedetomidine (Group D) or placebo (Group S). Group D received dexmedetomidine at 0.4 μg·kg-1·h-1 starting 15 minutes before surgery until completion, along with propofol at 1.5 mg/kg for anesthesia. Group S received saline and propofol in a similar manner. Anesthesia was maintained with dexmedetomidine at 0.4 μg·kg-1·h-1 and propofol at 1-2 mg/kg during surgery. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) preoperatively and on postoperative days 1, 3, and 5. Primary outcome was perioperative neurocognitive disorder (PND) incidence on day 5; secondary outcomes included changes in perioperative IL-6, cortisol, S100-β, hemodynamics, anesthesia parameters, postoperative pain, agitation scores, and adverse events. Results All 80 patients completed the trial. On postoperative day 5, the cumulative probability of PND incidence was significantly lower in Group D than in Group S (12.5% vs 35%, P=0.018). Group D also had lower levels of IL-6 (F=199.472, P<0.001), S100-β (F=2681.964, P<0.001), and cortisol (F=137.637, P<0.001). Propofol doses were lower in Group D (706.1 ± 202.4 vs 1003.3 ± 203.7, P<0.001), and bradycardia rates were higher (45% vs 15%, P=0.003), though atropine use did not significantly differ between groups. Group D showed greater stability in mean arterial pressure. Postoperative complications and adverse reactions were similar across groups. Conclusion Perioperative low-dose dexmedetomidine infusion with propofol in elderly ERCP patients ensures safe and effective monitored anesthesia care (MAC), reducing PND incidence by mitigating peripheral inflammation and stress responses. Long-term follow-up is needed to fully evaluate PND incidence.

Abstract
INTRODUCTION Recruitment, training, and retention of wartime critical specialty physicians may be stymied by discrimination and abuse. It is unclear to what extent the US combat specialty physicians witness or experience discrimination and abuse, whether they or others intervene, and if they would subsequently discourage people from entering their field. MATERIALS AND METHODS The present study surveyed US active duty anesthesiologists, emergency medicine physicians, and orthopedic surgeons (N = 243; 21% response rate). A generalized linear model evaluated the extent to which gender, specialty, service, and number of witnessed/experienced negative/stigmatizing comment/event types were associated with burnout. A bootstrapped mediation analysis evaluated whether gender and burnout were mediated by the number of comment/event types. RESULTS The sample was majority non-Latine White (87%) and men (66%) with tri-service and specialty representation. The most commonly reported negative/stigmatizing comment/event types were related to pregnancy (62%) and parental leave (61%), followed by gender and assigned sex (42%), lactation (37%), and sexual harassment (35%). Of the respondents who witnessed/experienced such comments/events, self-intervention was reported after comments regarding lactation (43%), assigned sex and gender (42%), race and ethnicity (41%), pregnancy (41%), parental leave (37%), and sexual harassment (24%). Witnessing another person intervene was reported after sexual harassment (25%) and comments/events regarding race and ethnicity (24%), pregnancy (20%), assigned sex and gender (19%), lactation (19%), and parental leave (18%). Nonintervention was reported after comments/events related to parental leave (42%), pregnancy (38%), sexual harassment (26%), lactation (26%), assigned sex and gender (26%), and race and ethnicity (22%). Respondents reported moderate-to-high intervening likelihood, importance, and confidence. Respondents reporting neutral to extremely agree on prompts indicating that pregnant active duty physicians are trying to avoid deployment (P = .002) and expect special treatment that burdens the department (P = .007) were disproportionately men (36% and 38%, respectively) compared to women (14% and 18%, respectively). The highest proportion of neutral to extremely agree responses regarding discouraging specialty selection were reported in relation to transgender and gender diverse students (21%), followed by cisgender female students (18%); gay, lesbian, or bisexual+ students (17%); cisgender male students (13%); and racial and ethnic minoritized students (12%). In the primary model, the number of witnessed/experienced comment/event types was associated with greater burnout (0.13, 95% CI 0.06-0.20, P = .001), but women did not report significantly different levels of burnout than men (0.20, 95% CI -0.10 to 0.51, P = 0.20). The number of comment/event types mediated the relationship between gender and burnout (0.18, 95% CI 0.06, 0.34; P < .001). CONCLUSIONS Although reported intervening confidence, likelihood, and importance were high, it is unclear whether perceptions correspond to awareness of intervention need and behaviors. Bivariate differences in burnout levels between men and women were fully explained by the number of comment types in the mediation model. Annual trainings may not effectively address workplace climate optimization; institutions should consider targeted policy and programmatic efforts to ensure effective, structurally responsive approaches.

Abstract
BACKGROUND Surgical care in the operating room (OR) contributes one-third of the greenhouse gas (GHG) emissions in healthcare. The European Association of Endoscopic Surgery (EAES) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) initiated a joint Task Force to promote sustainability within minimally invasive gastrointestinal surgery. METHODS A scoping review was conducted by searching MEDLINE via Ovid, Embase via Elsevier, Cochrane Central Register of Controlled Trials, and Scopus on August 25th, 2023 to identify articles reporting on the impact of gastrointestinal surgical care on the environment. The objectives were to establish the terminology, outcome measures, and scope associated with sustainable surgical practice. Quantitative data were summarized using descriptive statistics. RESULTS We screened 22,439 articles to identify 85 articles relevant to anesthesia, general surgical practice, and gastrointestinal surgery. There were 58/85 (68.2%) cohort studies and 12/85 (14.1%) Life Cycle Assessment (LCA) studies. The most commonly measured outcomes were kilograms of carbon dioxide equivalents (kg CO2eq), cost of resource consumption in US dollars or euros, surgical waste in kg, water consumption in liters, and energy consumption in kilowatt-hours. Surgical waste production and the use of anesthetic gases were among the largest contributors to the climate impact of surgical practice. Educational initiatives to educate surgical staff on the climate impact of surgery, recycling programs, and strategies to restrict the use of noxious anesthetic gases had the highest impact in reducing the carbon footprint of surgical care. Establishing green teams with multidisciplinary champions is an effective strategy to initiate a sustainability program in gastrointestinal surgery. CONCLUSION This review establishes standard terminology and outcome measures used to define the environmental footprint of surgical practices. Impactful initiatives to achieve sustainability in surgical practice will require education and multidisciplinary collaborations among key stakeholders including surgeons, researchers, operating room staff, hospital managers, industry partners, and policymakers.

Abstract
Purpose Strabismus surgery is most commonly performed on children under general anesthesia. However, few studies have focused on the postoperative discomfort in children after strabismus surgery. This study aimed to evaluate postoperative discomfort and the associated risk factors in children who underwent strabismus surgery under general anesthesia. Patients and Methods A single-center prospective observational study including 300 children who underwent strabismus surgery after general anesthesia was conducted. Patients' characteristics, preoperative anxiety, surgical and anesthesia data, discomfort within 24 hours after postanesthesia care unit were recorded. The primary outcome was the incidence of postoperative discomfort. Results Approximately 51.33% of the children complained of at least one of the following types of postoperative discomfort: postoperative nausea and vomiting (PONV) (23.00%), headache (4.33%), dizziness (20.33%) and emergence agitation (EA) (5.33%). Multivariate analysis indicated that history of motion sickness (P<0.001, odds ratio [OR]=3.72), and surgery in the dominant eye (P=0.010, OR=2.00) were independent predictors of postoperative discomfort; age was an independent predictor of EA (P<0.001, OR=0.36); prism diopter≥40 was an independent predictor of headache (P=0.005, OR=5.53); age (P=0.020, OR=1.12) and history of motion sickness (P=0.001, OR=2.80) were independent predictors of dizziness; history of motion sickness (P=0.001, OR=2.63) and surgery of inferior oblique anterior transposition (IOAT) (P=0.004, OR=3.10) were independent predictors of PONV. Conclusion The most frequent postoperative symptoms in children after undergoing strabismus surgery under general anesthesia are PONV, dizziness, EA, and headache. Younger age, larger angle of strabismus, history of motion sickness, surgery on the dominant eye, and surgery of IOAT may be additional risk factors for postoperative discomfort.

Abstract
Objectives Studies have shown that there are differences in clinical evaluation parameters and difficult intubation rates among different ethnic populations. In our study, we aimed to evaluate the efficacy of upper airway clinical and ultrasonographic measurement methods in Turkish population. Methods Our study is a single-center, prospective, observational study conducted with 402 patients. All patients underwent clinical airway measurements which are routinely used in pre-anesthetic evaluation. In addition, ultrasonographic anterior neck soft tissue thickness measurements of each patient were made and recorded. Results Among the clinical measurements, we found the neck circumference/thyromental distance (TMD) ratio to be significant with a cut-off value of 5.5 and a sensitivity of 92.9% and a specificity of 88.3%, while among the ultrasonographic anterior neck measurements, we found the skin-epiglottic distance to be the most sensitive measurement. We found that there was a positive relationship between the neck circumference/TMD ratio and skin-epiglottis. Conclusions In our study, we found that routine measurement methods used in airway examination alone are not sufficient, and measurements that take into account the body proportions of the patients, such as the neck circumference/TMD ratio and the ultrasonographic evaluations are more useful in predicting difficult intubation.

Abstract
A Gravida 2 Para 1 Live 1 in her late 20s and of South Asian ethnicity with previous lower segment caesarean section (LSCS) was hospitalised for confinement at 37 weeks for chronic hypertension with superimposed pre-eclampsia.The patient was diagnosed with type III Takayasu's arteritis following a previous uncomplicated pregnancy. A year after her first childbirth, she presented with headache, recurrent scleritis, hypertension, bilateral absent lower limb pulses and right femoral bruit. CT angiogram revealed concentric thickening of the aorta and complete occlusion of the infrarenal aorta, with a saccular aneurysm 18 mm in diameter in the distal thoracic aorta at the T10 level. She was started on immunosuppressants and antihypertensives. During the current pregnancy, she received multidisciplinary care and underwent an elective LSCS with intrauterine contraceptive device (IUCD) placement at term under spinal anaesthesia. Postoperatively, nitroglycerine infusion followed by oral labetalol was administered for hypertension. She was discharged on day 10 with regular follow-up.

Abstract
BACKGROUND Dysfunction of ventriculoperitoneal (VP) shunts can lead to decreased levels of consciousness. We report a case of delayed emergence from anesthesia due to the malfunction of a VP shunt during neurosurgery in the prone position. CASE PRESENTATION A 75-year-old male with a history of VP shunt for a fourth ventricle obstruction underwent cerebral vascular anastomosis in the prone position. His preoperative level of consciousness was clear. The surgery under general anesthesia was completed without any particular issues. After discontinuation of anesthesia, the patient did not awaken for over an hour. Postoperative CT revealed exacerbated hydrocephalus, likely from VP shunt occlusion. After pumping the reservoir of the VP shunt, the patient regained consciousness. He was extubated and discharged from ICU on the second postoperative day with no neurological issues. CONCLUSION For surgical patients with a VP shunt, anesthesia management must consider the risk of shunt malfunction due to patient positioning.

Abstract
BACKGROUND Mechanical ventilation is a core intervention in critical care, but may also lead to negative consequences. Therefore, ventilator weaning is crucial for patient recovery. Numerous weaning interventions have been investigated, but an overview of interventions to evaluate different foci on weaning research is still missing. AIM To provide an overview of interventions associated with ventilator weaning. STUDY DESIGN We conducted a scoping review. A systematic search of the Medline, CINAHL and Cochrane Library databases was carried out in May 2023. Interventions from studies or reviews that aimed to extubate or decannulate mechanically ventilated patients in intensive care units were included. Studies concerning children, outpatients or non-invasive ventilation were excluded. Screening and data extraction were conducted independently by three reviewers. Identified interventions were thematically analysed and clustered. RESULTS Of the 7175 records identified, 193 studies were included. A total of six clusters were formed: entitled enteral nutrition (three studies), tracheostomy (17 studies), physical treatment (13 studies), ventilation modes and settings (47 studies), intervention bundles (42 studies), and pharmacological interventions including analgesic agents (8 studies), sedative agents (53 studies) and other agents (15 studies). CONCLUSIONS Ventilator weaning is widely researched with a special focus on ventilation modes and pharmacological agents. Some aspects remain poorly researched or unaddressed (e.g. nutrition, delirium treatment, sleep promotion). RELEVANCE TO CLINICAL PRACTICE This review compiles studies on ventilator weaning interventions in thematic clusters, highlighting the need for multidisciplinary care and consideration of various interventions. Future research should combine different interventions and investigate their interconnection.

[PMID: 39153174 DOI: 10.1007/s12264-024-01265-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 03/15/2024] [Indexed: 08/19/2024] Open
Abstract
The primary intravenous anesthetics employed in clinical practice encompass dexmedetomidine (Dex), propofol, ketamine, etomidate, midazolam, and remimazolam. Apart from their established sedative, analgesic, and anxiolytic properties, an increasing body of research has uncovered neuroprotective effects of intravenous anesthetics in various animal and cellular models, as well as in clinical studies. However, there also exists conflicting evidence pointing to the potential neurotoxic effects of these intravenous anesthetics. The role of intravenous anesthetics for neuro on both sides of protection or toxicity has been rarely summarized. Considering the mentioned above, this work aims to offer a comprehensive understanding of the underlying mechanisms involved both in the central nerve system (CNS) and the peripheral nerve system (PNS) and provide valuable insights into the potential safety and risk associated with the clinical use of intravenous anesthetics.

[PMID: 39152950 DOI: 10.1016/j.jopan.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 04/10/2024] [Accepted: 04/10/2024] [Indexed: 08/19/2024]
Abstract
PURPOSE Postoperative pain is a common consequence of surgery. Pre-emptive analgesia involves the initiation of analgesics prior to surgical incision. This has been proposed as a simple method to help reduce postoperative pain, which may be more effective in higher-risk populations such as cervical spine surgery. A previous meta-analysis has demonstrated that pre-emptive acetaminophen may be effective in reducing postoperative pain although the certainty of evidence was limited. This present paper is an updated meta-analysis comparing pre-emptive acetaminophen versus postincision acetaminophen in adult patients undergoing surgery. DESIGN Systematic review and meta-analysis with the inclusion of an unpublished randomized, placebo-controlled, double-blind trial. METHODS An updated meta-analysis was conducted which searched electronic databases to identify randomized controlled trials with the same interventions. FINDINGS We included 845 participants and 12 studies in the updated meta-analysis. The meta-analysis (including our trial) found reduced 24-hour morphine consumption in the pre-emptive group (mean difference -2.42 mg; 95% confidence interval -4.26 to -0.59 mg), as well as reduced postoperative vomiting (risk ratio 0.56; 95% confidence interval 0.36 to 0.88). There was no difference between pre-emptive acetaminophen and control groups for time to analgesic request, pain scores at 6 and 24 hours or pruritis. For all outcomes assessed, there was very low certainty of evidence. CONCLUSIONS This meta-analysis found pre-emptive acetaminophen reduced 24-hour opioid consumption and postoperative vomiting.

Abstract
PURPOSE Intraoperative hypoglycemia is presumed to be rare, but generalizable multicentre incidence and risk factor data for adult patients are lacking. We used a multicentre registry to characterize adults with intraoperative hypoglycemia and hypothesized that intraoperative insulin administration would be associated with hypoglycemia. METHODS We conducted a cross-sectional retrospective multicentre cohort study. We searched the Multicenter Perioperative Outcomes Group registry to identify adult patients with intraoperative hypoglycemia (glucose < 3.3 mmol·L-1 [< 60 mg·dL-1]) from 1 January 2015 to 31 December 2019. We evaluated characteristics of patients with intraoperative glucose measurements and with intraoperative hypoglycemia. RESULTS Of 516,045 patients with intraoperative glucose measurements, 3,900 (0.76%) had intraoperative hypoglycemia. Diabetes mellitus and chronic kidney disease were more common in the cohort with intraoperative hypoglycemia. The odds of intraoperative hypoglycemia were higher for the youngest age category (18-30 yr) compared with the odds for every age category above 40 yr (odds ratio [OR], 1.57-3.18; P < 0.001), and were higher for underweight or normal weight patients compared with patients with obesity (OR, 1.48-2.53; P < 0.001). Parenteral nutrition was associated with lower odds of hypoglycemia (OR, 0.23; 95% confidence interval [CI], 0.11 to 0.47; P < 0.001). Intraoperative insulin use was not associated with hypoglycemia (OR, 0.996; 95% CI, 0.91 to 1.09; P = 0.93). CONCLUSION In this large cross-sectional retrospective multicentre cohort study, intraoperative hypoglycemia was a rare event. Intraoperative insulin use was not associated with hypoglycemia.

Abstract
OBJECTIVE In this study, we evaluated the efficacy and safety of 1 μg/kg dexmedetomidine as an adjuvant treatment to ropivacaine in children undergoing upper limb surgeries under ultrasound-guided axillary brachial plexus blocks and general anesthesia. METHODS We enrolled 90 children (aged 1-8 years; ASA I-II) undergoing closed reduction and internal fixation for upper extremity fractures at the Xiamen Children's Hospital and randomly assigned them to one of two groups: L (injection with 0.25% ropivacaine) or D (injection with 0.25% ropivacaine containing 1 μg/kg dexmedetomidine) using the random number table method. The main outcome indicators recorded were the facial expression, leg activity, position, crying, and Face, Legs, Activity, Cry, and Consolability (FLACC) scale scores of children after surgery and the duration of block and analgesia maintenance. The secondary outcome indicators were vital sign data at the time of ultrasound probe placement (T1), at the time of block completion (T2), prior to the beginning of surgery (T3), 5 min after the beginning of surgery (T4), and at the end of surgery (T5), as well as the time of postoperative recovery, the number of cases of remedial analgesia, and complications. RESULTS There was no statistical difference between the two groups in terms of general data, block completion time, postoperative recovery time, and complications (P > 0.05). Compared to the L group, the D group had significantly lower FLACC scores at 6 h after surgery, as well as significantly lower systolic blood pressure, diastolic blood pressure, and heart rate values at T4 and T5, and significantly longer duration of postoperative analgesia maintenance (all P < 0.05). CONCLUSION Dexmedetomidine (1 μg/kg) as a local anesthetic adjuvant to ropivacaine can alleviate pain at 6 h postoperatively, prolong analgesia maintenance, and reduce intraoperative blood pressure and heart rate in pediatric patients undergoing closed reduction and internal fixation for upper extremity fractures, with no obvious complications or delayed recovery.

Abstract
Laparoscopic cholecystectomy can be associated with significant postoperative pain that is difficult to treat. We aimed to evaluate the available literature and develop updated recommendations for optimal pain management after laparoscopic cholecystectomy. A systematic review was performed using the procedure-specific postoperative pain management (PROSPECT) methodology. Randomised controlled trials and systematic reviews published in the English language from August 2017 to December 2022 assessing postoperative pain after laparoscopic cholecystectomy using analgesic, anaesthetic or surgical interventions were identified from MEDLINE, Embase and Cochrane Databases. From 589 full text articles, 157 randomised controlled trials and 31 systematic reviews met the inclusion criteria. Paracetamol combined with NSAIDs or cyclo-oxygenase-2 inhibitors should be given either pre-operatively or intra-operatively, unless contraindicated. In addition, intra-operative intravenous (i.v.) dexamethasone, port-site wound infiltration or intraperitoneal local anaesthetic instillation are recommended, with opioids used for rescue analgesia. As a second-line regional technique, the erector spinae plane block or transversus abdominis plane block may be reserved for patients with a heightened risk of postoperative pain. Three-port laparoscopy, a low-pressure pneumoperitoneum, umbilical port extraction, active aspiration of the pneumoperitoneum and saline irrigation are recommended technical aspects of the operative procedure. The following interventions are not recommended due to limited or no evidence on improved pain scores: single port or mini-port techniques, routine drainage, low flow insufflation, natural orifice transluminal endoscopic surgery (NOTES), infra-umbilical incision, i.v. clonidine, nefopam and regional techniques such as quadratus lumborum block or rectus sheath block. Several interventions provided better pain scores but are not recommended due to risk of side effects: spinal or epidural anaesthesia, gabapentinoids, i.v. lidocaine, i.v. ketamine and i.v. dexmedetomidine.

Abstract
BACKGROUND Studies have proposed that the routine use of sugammadex could provide perioperative time savings and a reduction in the incidence of postoperative nausea and vomiting. The purpose of this study was to test the effectiveness of sugammadex on perioperative times and on the incidences of adverse events when compared with the active control, neostigmine, for minimally invasive gastric sleeve surgery. METHODS Following institutional review board approval, patient characteristics, type of primary neuromuscular blocking reversal agents, operating room discharge times, post-anaesthesia care unit recovery times, and incidences of and treatment for postoperative nausea and vomiting and orotracheal reintubation were the measures of interest. Superiority testing determined the between-group means differences of the reversal agents on the two perioperative time periods of interest. RESULTS Superiority testing demonstrated no improvement of the two perioperative times with sugammadex. There was no clinical difference in the incidence of postoperative nausea and vomiting or in the number of antiemetic doses received in the post-anaesthesia care unit between the two groups. Finally, the two orotracheal reintubations in the post-anaesthesia care unit were in the sugammadex administered group. CONCLUSION These results with sugammadex provide no perioperative time savings or reduce the incidence and treatment for postoperative nausea and vomiting in the post-anaesthesia care unit when compared with neostigmine.

Abstract
BACKGROUND Spinal anesthesia (SA) is a conventional method for proper nerve block in abdominopelvic and lower extremity surgeries. Compared to general anesthesia, SA has reduced perioperative complications significantly. The hyperbaric type of bupivacaine hydrochloride (HB) induces spinal anesthesia more efficiently with a lower incidence of life-threatening adverse reactions like Perioperative hemodynamic changes and respiratory depression. More investigations are needed to define the best dosage that provides adequate anesthesia while reducing adverse effects for each surgical procedure. METHODS This double-blinded randomized clinical trial compared the consequences of the (12.5mg,15mg,20mg) dosages of HB-bupivacaine in elective lower limb orthopedic surgery. Using block randomization, we allocated 60 participants to three (n = 20) study groups. Utilizing the same protocol of anesthesia induction, outcome variables assumed and measured as the incidence of the adverse effects (Hypotension, Anxiety, Bradycardia, Nausea and Vomiting(N/V), Hypoventilation, and Decreased o2 saturation), and the requirement for intervention to control the unwanted reaction. Addressing that, outcome variables were measured 10 times perioperatively. One-way ANOVA test, the chi2 test, or repeated measures ANOVA test with the Bonferroni adjustment were utilized as appropriate. RESULTS We found that the incidence of hypotension (P-value:0.02) and the N/V (P-value < 0.001) are associated with the HB-bupivacaine dosage. Contrary, our findings indicate that the incidence of apnea, bradycardia, and hypoventilation did not exhibit a significant dose-dependent pattern between the groups. Repeated measures analysis revealed significant intergroup differences for Herat rate, systolic, diastolic, and mean arterial pressure (group*time Pvalue < 0.001). The observed differences were more prominent 10-30 min after injection of HB-bupivacaine. The regression model claimed that gender (P-value:0.002) and drug dosage (P-value:0.03) significantly predict the incidence of adverse effects. CONCLUSION Our results, suggest that the administration of the 12.5mg HB-bupivacaine provides adequate anesthesia while minimizing the risk of adverse events for lower limb orthopedic surgeries lasting up to 180 min.

Analgesic efficacy and safety of erector spinae plane block in pediatric patients undergoing elective surgery: A systematic review and Meta-analysis of randomized controlled trials. J Clin Anesth 2024; 98:111575. [PMID: 39128258 DOI: 10.1016/j.jclinane.2024.111575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 07/07/2024] [Accepted: 08/04/2024] [Indexed: 08/13/2024]
Abstract
STUDY OBJECTIVE Ultrasound-guided erector spinae plane block (ESPB) is commonly used for perioperative analgesia in adults; however, its analgesic efficacy and safety in pediatric patients remain uncertain. This review aimed to determine whether ultrasound-guided ESPB can improve analgesic efficacy and safety in pediatric surgery. DESIGN Meta-analysis of randomized controlled trials. SETTING Perioperative setting. PATIENTS Pediatric patients undergoing elective surgery under general anesthesia. INTERVENTIONS We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, KoreaMed, Web of Science, Scopus, and ClinicalTrials.gov databases for eligible published randomized controlled studies (RCTs) comparing ESPB with controls (no block or other block) in pediatric patients undergoing elective surgery under general anesthesia. MEASUREMENTS The primary outcome was cumulative opioid consumption after surgery. Other outcomes included intraoperative opioid consumption, time to first request for rescue analgesia, number of patients requiring rescue analgesics, and pain scores after surgery. The safety outcomes were the incidences of bradycardia, hypotension, and postoperative vomiting. MAIN RESULTS The analysis included 17 RCTs comprising 919 participants: 461 in the ESPB group, 269 in the no-block group (no block/sham block), and 189 in the other block group. Compared with the control group (no block and other blocks), ESPB significantly reduced the cumulative opioid consumption (intravenous morphine milligram equivalents) after surgery (standardized mean difference = -1.51; 95% confidence interval, -2.39 to -0.64; P = 0.0002; I2 = 92.9%) and intraoperative opioid consumption, and lowered average pain scores up to 24 h after surgery. ESPB extended the time to the first request for rescue analgesia and decreased the number of patients requiring rescue analgesics. Furthermore, ESPB lowered the pain score at most time points for 24 h after surgery, improved parental satisfaction, and reduced the incidence of postoperative vomiting compared with that in no block/sham block. CONCLUSIONS ESPB provides effective and safe perioperative analgesia in pediatric patients undergoing elective surgery under general anesthesia.

Abstract
BACKGROUND This study compares the effect of positive end-expiratory pressure (PEEP) on postoperative pulmonary complications (PPCs) in patients with obesity undergoing laparoscopic bariatric surgery (LBS) under general anesthesia with mechanical ventilation. METHODS A comprehensive search was conducted in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China National Knowledge Internet, Wanfang database, and Google Scholar for studies published up to July 29, 2023, without time or language restrictions. The search terms included "PEEP," "laparoscopic," and "bariatric surgery." Randomized controlled trials comparing different levels of PEEP or PEEP with zero-PEEP (ZEEP) in patients with obesity undergoing LBS were included. The primary outcome was a composite of PPCs, and the secondary outcomes were intraoperative oxygenation, respiratory compliance, and mean arterial pressure (MAP). A fixed-effect or random-effect model was selected for meta-analysis based on the heterogeneity of the included studies. RESULTS Thirteen randomized controlled trials with a total of 708 participants were included for analysis. No statistically significant difference in PPCs was found between the PEEP and ZEEP groups (risk ratio = 0.27, 95% CI: 0.05-1.60; p = 0.15). However, high PEEP ≥ 10 cm H2O significantly decreased PPCs compared with low PEEP < 10 cm H2O (risk ratio = 0.20, 95% CI: 0.05-0.89; p = 0.03). The included studies showed no significant heterogeneity (I2 = 20% & 0%). Compared with ZEEP, PEEP significantly increased intraoperative oxygenation and respiratory compliance (WMD = 74.97 mm Hg, 95% CI: 41.74-108.21; p < 0.001 & WMD = 9.40 ml cm H2O- 1, 95% CI: 0.65-18.16; p = 0.04). High PEEP significantly improved intraoperative oxygenation and respiratory compliance during pneumoperitoneum compared with low PEEP (WMD = 66.81 mm Hg, 95% CI: 25.85-107.78; p = 0.001 & WMD = 8.03 ml cm H2O- 1, 95% CI: 4.70-11.36; p < 0.001). Importantly, PEEP did not impair hemodynamic status in LBS. CONCLUSIONS In patients with obesity undergoing LBS, high PEEP ≥ 10 cm H2O could decrease PPCs compared with low PEEP < 10 cm H2O, while there was a similar incidence of PPCs between PEEP (8-10 cm H2O) and the ZEEP group. The application of PEEP in ventilation strategies increased intraoperative oxygenation and respiratory compliance without affecting intraoperative MAP. A PEEP of at least 10 cm H2O is recommended to reduce PPCs in patients with obesity undergoing LBS. REGISTRATION NUMBER CRD42023391178 in PROSPERO.

Abstract
OBJECTIVE This retrospective study aimed to compare rates of perioperative mortality and morbidity, especially pulmonary complication, between endovascular aneurysm repair (EVAR) performed under general anesthesia (GA) and under fascia iliaca block (FIB). METHODS Patients diagnosed with infrarenal abdominal aortic aneurysm (AAA) who were treated with EVAR were included. Retrospective review of electronic medical records was performed. Patient characteristics, operative details, and postoperative results including mortality and morbidity within 30 days were collected. Statistical analysis to compare postoperative outcomes between EVAR under FIB and EVAR under GA was performed. A univariate analysis was conducted to identify factors associated with increased 30-day mortality. RESULTS This study included 119 patients, 75 in the FIB group and 44 in the GA group. Most patients were male, with 62 (82.5%) in the FIB group and 31 (70.2%) in the GA group, and most patients were hypertensive, with 57 (76%) in the FIB group and 36 (81.8%) in the GA group. Smoking and coronary artery disease (CAD) was more prevalent in the FIB group, p < .05. Thirty-day mortality was not significantly different between the FIB group and the GA group (1 (1.3%) vs 2 (4.5%), p = .554). Pulmonary complication was lower in the FIB group than in the GA group (1.3% vs 11.4%, p = .026). ICU stay was shorter in the FIB group than in the GA group (0.2 vs 4.5 days, p = .012). Univariate analysis showed that chronic obstructive pulmonary disease (COPD) was associated with higher 30-day mortality. CONCLUSIONS Endovascular aneurysm repair under FIB was feasible. Compared to GA, this approach resulted in lower postoperative pulmonary complications and shorter ICU stay.

Abstract
BACKGROUND Ketamine has recently attracted considerable attention for its rapid effects on patients with major depressive disorder, including treatment-resistant depression (TRD). Despite ketamine's promising results in treating depression, a significant number of patients do not respond to the treatment, and predicting who will benefit remains a challenge. Although its antidepressant effects are known to be linked to its action as an antagonist of the N-methyl-D-aspartate (NMDA) receptor, the precise mechanisms that determine why some patients respond and others do not are still unclear. OBJECTIVE This study aims to understand the computational mechanisms underlying changes in the auditory mismatch negativity (MMN) response following treatment with intravenous ketamine. Moreover, we aim to link the computational mechanisms to their underlying neural causes and use the parameters of the neurocomputational model to make individual treatment predictions. METHODS This is a prospective study of 30 patients with TRD who are undergoing intravenous ketamine therapy. Prior to 3 out of 4 ketamine infusions, EEG will be recorded while patients complete the auditory MMN task. Depression, suicidality, and anxiety will be assessed throughout the study and a week after the last ketamine infusion. To translate the effects of ketamine on the MMN to computational mechanisms, we will model changes in the auditory MMN using the hierarchical Gaussian filter, a hierarchical Bayesian model. Furthermore, we will employ a conductance-based neural mass model of the electrophysiological data to link these computational mechanisms to their neural causes. CONCLUSION The findings of this study may improve understanding of the mechanisms underlying response and resistance to ketamine treatment in patients with TRD. The parameters obtained from fitting computational models to EEG recordings may facilitate single-patient treatment predictions, which could provide clinically useful prognostic information.

[PMID: 39127927 DOI: 10.1016/j.jopan.2024.03.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 03/19/2024] [Accepted: 03/28/2024] [Indexed: 08/12/2024]
Abstract
PURPOSE Postoperative sore throat (POST) is a major complaint after day-case surgery. The objectives of this study were to investigate the risk factors for POST and develop a stratified nursing model for POST after day-case surgery. DESIGN This case-control study was conducted at Department of Anesthesiology of 1st Affiliated Hospital of Wenzhou Medical University in Wenzhou, Zhejiang, China. METHODS Anesthesia records and postanesthesia care files of adult patients undergoing day-case surgery with general anesthesia were reviewed. The primary outcome was the incidence of POST at 24 hours after day-case surgery or before discharge within 24 hours. Multivariate logistics regression was used to identify risk factors for POST. A nomogram was created to predict the probability of POST after day-case surgery. FINDINGS A total of 9,312 records were retrieved from June 1, 2021 to April 30, 2022, including 8,499 files in the training group and 813 files in the validation group. One thousand five hundred and twenty-five cases in the training group experienced POST. The independent risk factors for POST included: thyroid surgery (odds ratios [OR] = 22.42, 95% confidence intervals [CI]: 18.45 to 27.25), shorter thyromental distance (OR = 1.18, 95% CI: 1.06 to 1.30), smaller neck circumference (OR = 1.09, 95% CI: 1.06 to 1.11), duration of anesthesia (OR = 1.13, 95% CI: 1.04 to 1.22), female (OR = 1.66, 95% CI: 1.41 to 1.96), age (OR = 0.99, 95% CI: 0.99 to 1.00) and the presence of bloody sputum (OR = 8.33, 95% CI: 6.53 to 10.63). A nomogram that involved five factors was established to predict the probability of POST after day-case surgery. The area under the receiver operating characteristic curve in the training and validation groups was 0.77 and 0.81, respectively. The calibration curve demonstrated good consistency between the actual POST and the predicted probability. CONCLUSIONS The following variables are independently associated with POST: thyroid surgery, age approaching to 40 years old, female, shorter thyromental distance and smaller neck circumference, longer duration of anesthesia, and the presence of bloody sputum. A novel stratified nursing model is feasible for predicting the probability of POST.

Abstract
Sepsis is a critical global health concern linked to high mortality rates, often due to acute lung injury (ALI)/acute respiratory distress syndrome (ARDS). While the gut-lung axis involvement in ALI is recognized, direct migration of gut immune cells to the lung remains unclear. Our study reveals sepsis-induced migration of γδ T17 cells from the small intestine to the lung, triggering an IL-17A-dominated inflammatory response in mice. Wnt signaling activation in alveolar macrophages drives CCL1 upregulation, facilitating γδ T17 cell migration. CD44+ Ly6C- IL-7Rhigh CD8low cells are the primary migratory subtype exacerbating ALI. Esketamine attenuates ALI by inhibiting pulmonary Wnt/β-catenin signaling-mediated migration. This work underscores the pivotal role of direct gut-to-lung memory γδ T17 cell migration in septic ALI and clarifies the importance of localized IL-17A elevation in the lung.

World J Clin Cases 2024; 12:4947-4955. [DOI: 10.12998/wjcc.v12.i22.4947] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 05/22/2024] [Accepted: 06/05/2024] [Indexed: 06/30/2024] Open
Abstract
BACKGROUND Preschoolers become anxious when they are about to undergo anesthesia and surgery, warranting the development of more appropriate and effective interventions.
AIM To explore the effect of static cartoons combined with dynamic virtual environments on preoperative anxiety and anesthesia induction compliance in preschool-aged children undergoing surgery.
METHODS One hundred and sixteen preschool-aged children were selected and assigned to the drug (n = 37), intervention (n = 40), and control (n = 39) groups. All the children received routine preoperative checkups and nursing before being transferred to the preoperative preparation room on the day of the operation. The drug group received 0.5 mg/kg midazolam and the intervention group treatment consisting of static cartoons combined with dynamic virtual environments. The control group received no intervention. The modified Yale Preoperative Anxiety Scale was used to evaluate the children’s anxiety level on the day before surgery (T0), before leaving the preoperative preparation room (T1), when entering the operating room (T2), and at anesthesia induction (T3). Compliance during anesthesia induction (T3) was evaluated using the Induction Compliance Checklist (ICC). Changes in mean arterial pressure (MAP), heart rate (HR), and respiratory rate (RR) were also recorded at each time point.
RESULTS The anxiety scores of the three groups increased variously at T1 and T2. At T3, both the drug and intervention groups had similar anxiety scores, both of which were lower than those in the control group. At T1 and T2, MAP, HR, and RR of the three groups increased. The drug and control groups had significantly higher MAP and RR than the intervention group at T2. At T3, the MAP, HR, and RR of the drug group decreased and were significantly lower than those in the control group but were comparable to those in the intervention group. Both the drug and intervention groups had similar ICC scores and duration of anesthesia induction (T3), both of which were higher than those of the control group.
CONCLUSION Combining static cartoons with dynamic virtual environments as effective as medication, specifically midazolam, in reducing preoperative anxiety and fear in preschool-aged children. This approach also improve their compliance during anesthesia induction and helped maintain their stable vital signs.

Abstract
INTRODUCTION Ultrasound-guided quadratus lumborum blocks are commonly used for postoperative analgesia during caesarean section. Ultrasound-guided quadratus lumborum blocks can be performed through four approaches, including lateral, posterior, anterior, and intramuscular quadratus lumborum blocks. This systematic review and meta-analysis aims to determine the optimal approach to ultrasound-guided quadratus lumborum blocks for postoperative analgesia in elective caesarean section. METHODS AND ANALYSIS The PubMed, EMBASE, Cochrane Library and Web of Science databases will be systematically searched from their inception to 30 July 2024. Randomised controlled trials that compared the analgesic effects of different ultrasound-guided quadratus lumborum block approaches in elective caesarean section will be included. Only publications in English will be eligible for inclusion. The total postoperative analgesic consumption over 24 hours will be the primary outcome. The time to first analgesic request, postoperative pain scores at rest and during movement, and incidence of adverse effects will be secondary outcomes. RevMan V.5.4 will be used for the statistical analysis. Network meta-analysis will be used for indirect comparisons between different approaches across studies. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to assess the quality of evidence for each outcome. ETHICS AND DISSEMINATION Ethical approval was not required. The results of this study will be submitted to peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42024503694.

The median effective concentration of epidural ropivacaine with different doses of dexmedetomidine for motor blockade: an up-down sequential allocation study. Front Med (Lausanne) 2024; 11:1413191. [PMID: 39161411 PMCID: PMC11330782 DOI: 10.3389/fmed.2024.1413191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 07/26/2024] [Indexed: 08/21/2024] Open
Abstract
Study objective Recent studies have shown that dexmedetomidine can be safely used in peripheral nerve blocks and spinal anesthesia. Epidural administration of dexmedetomidine produces analgesia and sedation, prolongs motor and sensory block time, extends postoperative analgesia, and reduces the need for rescue analgesia. This investigation seeks to identify the median effective concentration (EC50) of ropivacaine for epidural motor blockade, and assess how incorporating varying doses of dexmedetomidine impacts this EC50 value. Design Prospective, double-blind, up-down sequential allocation study. Setting Operating room, post-anesthesia care unit, and general ward. Interventions One hundred and fifty patients were allocated into five groups in a randomized, double-blinded manner as follows: NR (normal saline combined with ropivacaine) group, RD0.25 (0.25 μg/kg dexmedetomidine combined with ropivacaine) group, RD0.5 (0.5 μg/kg dexmedetomidine combined with ropivacaine) group, RD0.75 (0.75 μg/kg dexmedetomidine combined with ropivacaine) group, RD1.0 (1.0 μg/kg dexmedetomidine combined with ropivacaine) group. The concentration of epidural ropivacaine for the first patient in each group was 0.5%. Following administration, the patients were immediately placed in a supine position for observation, and the lower limb motor block was assessed every 5 min using the modified Bromage score within 30 min after drug administration. According to the sequential method, the concentration of ropivacaine in the next patient was adjusted according to the reaction of the previous patient: effective motor block was defined as the modified Bromage score > 0 within 30 min after epidural administration. If the modified Bromage score of the previous patient was >0 within 30 min after drug administration, the concentration of ropivacaine in the next patient was decreased by 1 gradient. Conversely, if the score did not exceed 0, the concentration of ropivacaine in the next patient was increased by 1 gradient. The up-down sequential allocation method and probit regression were used to calculate the EC50 of epidural ropivacaine. Measurements Adverse events, hemodynamic changes, demographic data and clinical characteristics. Main results The EC50 of epidural ropivacaine required to achieve motor block was 0.677% (95% CI, 0.622-0.743%) in the NR group, 0.624% (95% CI, 0.550-0.728%) in the RD0.25 group, 0.549% (95% CI, 0.456-0.660%) in the RD0.5 group, 0.463% (95% CI, 0.408-0.527%) in the RD0.75 group, and 0.435% (95% CI, 0.390-0.447%) in the RD1.0 group. The EC50 of the NR group and the RD0.25 group were significantly higher than that of the RD0.75 and the RD1.0 groups, and the EC50 of the RD0.5 group was significantly higher than that of the RD1.0 group. Conclusion The EC50 of epidural ropivacaine required to achieve motor block was 0.677% in the NR group, 0.624% in the RD0.25 group, 0.549% in the RD0.5 group, 0.463% in the RD0.75 group, and 0.435% in the RD1.0 group. Dexmedetomidine as an adjuvant for ropivacaine dose-dependently reduce the EC50 of epidural ropivacaine for motor block and shorten the onset time of epidural ropivacaine block. The optimal dose of dexmedetomidine combined with ropivacaine for epidural anesthesia was 0.5 μg/kg.

Abstract
INTRODUCTION Limited non-opioid analgesic options are available for managing postoperative pain after renal transplantation. We aimed to investigate whether the unilateral anterior quadratus lumborum (QL) block would reduce postoperative opioid consumption after living-donor renal transplantation in the context of multimodal analgesia. METHODS Eighty-eight adult patients undergoing living-donor renal transplantation were randomly allocated to receive the unilateral anterior QL block (30 mL of ropivacaine 0.375%) or sham block (normal saline) on the operated side before emergence from anesthesia. All patients received standard multimodal analgesia, including the scheduled administration of acetaminophen and fentanyl via intravenous patient-controlled analgesia. The primary outcome was the total opioid consumption during the first 24 hours after transplantation. The secondary outcomes included pain scores, time to first opioid administration, cutaneous distribution of sensory blockade, motor weakness, nausea/vomiting, quality of recovery scores, time to first ambulation, and length of hospital stay. RESULTS The total opioid consumption in the first 24 hours after transplantation did not differ significantly between the intervention and control groups (median (IQR), 160.5 (78-249.8) vs 187.5 (93-309) oral morphine milligram equivalent; median difference (95% CI), -27 (-78 to 24), p=0.29). No differences were observed in the secondary outcomes. CONCLUSIONS The anterior QL block did not reduce opioid consumption in patients receiving multimodal analgesia after living-donor renal transplantation. Our findings do not support the routine administration of the anterior QL block in this surgical population. TRIAL REGISTRATION NUMBER NCT04908761.

Abstract
BACKGROUND Intrathecal morphine provides effective analgesia for a range of operations. However, widespread implementation into clinical practice is hampered by concerns for potential side-effects. We undertook a systematic review, meta-analysis, and meta-regression with the primary objective of determining whether a threshold dose for non-pulmonary complications could be defined and whether an association could be established between dose and complication rates when intrathecal morphine is administered for perioperative or obstetric analgesia. METHODS We systematically searched the literature for randomised controlled trials comparing intrathecal morphine vs control in patients undergoing any type of surgery under general or spinal anaesthesia, or women in labour. Primary outcomes were rates of postoperative nausea and vomiting, pruritus, and urinary retention within the first 24 postoperative hours, analysed according to doses (1-100 μg; 101-200 μg; 201-500 μg; >500 μg), type of surgery, and anaesthetic strategy. Trials were excluded if doses were not specified. RESULTS Our analysis included 168 trials with 9917 patients. The rates of postoperative nausea and vomiting, pruritus, and urinary retention were significantly increased in the intrathecal morphine group, with an odds ratio (95% confidence interval) of 1.52 (1.29-1.79), P<0.0001; 6.11 (5.25-7.10), P<0.0001; and 1.73 (1.17-2.56), P=0.005, respectively. Meta-regression could not establish an association between dose and rates of non-pulmonary complications. There was no subgroup difference according to surgery for any outcome. The quality of evidence was low (Grading of Recommendations Assessment, Development, and Evaluation [GRADE] system). CONCLUSIONS Intrathecal morphine significantly increased postoperative nausea and vomiting, pruritus, and urinary retention after surgery or labour in a dose-independent manner.

Abstract
OBJECTIVES While significant evidence supports the benefits of normothermic cardiopulmonary bypass (NCPB) over hypothermic techniques, many institutions in developing countries, including ours, continue to employ hypothermic methods. This study aimed to assess the early postoperative outcomes of normothermic cardiopulmonary bypass (NCPB) for complete surgical repair via the Tetralogy of Fallot (TOF) within our national context. METHODS We conducted this study in the Pediatric Cardiac Intensive Care Unit (PCICU) at the University Children's Hospital. One hundred patients who underwent complete TOF repair were enrolled and categorized into two groups: the normothermic group (n = 50, temperature 35-37 °C) and the moderate hypothermic group (n = 50, temperature 28-32 °C). We evaluated mortality, morbidity, and postoperative complications in the PCICU as outcome measures. RESULTS The demographic characteristics were similar between the two groups. However, the cardiopulmonary bypass (CPB) time and aortic cross-clamp (ACC) time were notably longer in the hypothermic group. The study recorded seven deaths, yielding an overall mortality rate of 7%. No significant differences were observed between the two groups concerning mortality, morbidity, or postoperative complications in the PCICU. CONCLUSIONS Our findings suggest that normothermic procedures, while not demonstrably effective, are safe for pediatric cardiac surgery. Further research is warranted to substantiate and endorse the adoption of this technique.

Abstract
Inhalational anaesthetic agents are routinely used in veterinary anaesthesia practices, yet their consumption contributes significantly to greenhouse gas emissions and environmental impact. We conducted a 55-day observational study at a veterinary teaching hospital in Switzerland, monitoring isoflurane and sevoflurane consumption across small, equine and farm animal clinics and analysed the resulting environmental impact. Results revealed that in total, 9.36 L of isoflurane and 1.27 L of sevoflurane were used to anaesthetise 409 animals across 1,489 h. Consumption rates varied among species, with small and farm animals ranging between 8.7 and 13 mL/h, while equine anaesthesia exhibited a higher rate, 41.2 mL/h. Corresponding to 7.36 tonnes of carbon dioxide equivalent in total environmental emissions or between 2.4 and 31.3 kg of carbon dioxide equivalent per hour. Comparison to human anaesthesia settings showed comparable consumption rates to small animals, suggesting shared environmental implications, albeit on a smaller scale. This research highlights the importance of continued evaluation of veterinary anaesthesia practices to balance patient safety with environmental stewardship; potential mitigation strategies are explored and discussed.

Abstract
Background/Objective: Wound infiltration with local anesthetics emerges as a promising modality for postoperative pain alleviation. However, such strategies in neck surgery have not been a well-established practice. To assess wound infiltration with ropivacaine plus magnesium sulfate for pain relief following thyroid surgery. Methods: This prospective, double-blind, randomized study enrolled 68 patients who underwent thyroid surgery. Concerning the solution used for surgical wound infiltration, the study participants were randomly allocated into three groups: (1) 100 mg of ropivacaine (Group R); (2) 100 mg of ropivacaine plus magnesium sulfate 10 mg/kg (Group RMg); and (3) normal saline which served as a placebo (Group P). Pain perception both at rest and at movement, was measured using the Visual Analogue Scale (VAS) at 30 min, as well as at 1, 2, 4, 6, 12, and 24 h postoperatively. The total consumption of analgesics in morphine equivalents was also recorded. Moreover, adverse effects and patient satisfaction were recorded. Cortisol, TNF-α, and IL-6 levels were measured 30 min before infiltration and 6 h and 24 h postoperatively. Results: Demographics and clinical characteristics were similar between the groups. The VAS scores at rest and during movement were significantly lower in the RMg group compared to the saline or ropivacaine groups. Total analgesic consumption was also significantly lower in the RMg group. No operation-, wound-, or infiltration-related adverse effects were recorded in the study groups. Better overall satisfaction was obtained for the RMg group. Conclusions: Ropivacaine plus magnesium sulfate wound infiltration provided better pain control and the analgesic effect was more significant, contributing to effective postoperative analgesia in patients undergoing thyroid surgery.
