Abstract
PURPOSE We aimed to describe the current literature concerning propofol misuse in medical professionals, specifically relating to the individual demographics of those misusing propofol and the outcomes of propofol misuse. METHODS We conducted a retrospective scoping review of the literature using a modified PRISMA approach. We used MEDLINE, EMBASE, and PsycINFO databases to identify relevant studies based on search terms. Studies describing individual medical professionals misusing propofol were included. RESULTS Twenty-four articles describing 88 individual cases of propofol misuse were included for data charting and analysis. Anesthesiologists and certified registered nurse anesthetists were most commonly identified. Death was a common method of identification of misuse, while rehabilitation and death were common final outcomes associated with propofol misuse. CONCLUSIONS Despite knowledge of the pharmacokinetic and pharmacodynamic properties of propofol by those misusing this medication, death was a common outcome reported in the literature. Data related to long-term outcomes including re-entry to clinical practice or success of rehabilitation were limited.

Abstract
Context: Palliative sedation therapy (PST) can address suffering at the end of life (EOL) in children with cancer; yet, little is known about PST in this population. Objectives: We sought to describe the characteristics of pediatric oncology patients requiring PST at the EOL. Methods: A retrospective review was completed for pediatric oncology patients who required PST at a United States academic institution over 10 years, including demographics, disease characteristics, EOL characteristics, and medications for PST and symptom management. Results: PST was utilized in 3% of patients at the EOL. Of 24 study participants receiving PST, 83% (n = 20), 12.5% (n = 3), and 4.2% (n = 1) received dexmedetomidine, propofol, or both, respectively. The most frequent diagnosis for patients receiving PST was acute myelogenous leukemia (20.8%, n = 5). All patients were followed up by the palliative care team, and two-thirds (66.6%, n = 16) were also followed up by the pain management service; 79% (n = 19) were enrolled in hospice, and 98.5% (n = 23) had a Physician Orders for Scope of Treatment in place. Pain was the most common refractory symptom leading to PST initiation (33.3%, n = 8), followed by neuroagitation and dyspnea. PST was initiated a median of 2.5 days before death. A third of deaths occurred in the intensive care unit (33.3%, n = 8). Conclusions: PST was rare in this study; dexmedetomidine was used as first-line treatment for PST in patients at the EOL with refractory symptoms. Its place in PST protocols in pediatric oncology should be validated with prospective studies. Our study suggests the potential value of collaboration between palliative care and pain specialists in the context of PST.

Abstract
OBJECTIVE The authors aimed to compare the anti-inflammatory and antioxidant effects of propofol and sevoflurane in children with cyanotic congenital heart disease (CCHD) undergoing cardiac surgery with cardiopulmonary bypass. DESIGN Prospective, randomized, double-blind study. SETTING Single center, university hospital. PARTICIPANTS Children ages 1-10 years with CCHD undergoing elective cardiac surgery with cardiopulmonary bypass. INTERVENTIONS Children were randomized to receive general anesthesia with either sevoflurane (group S) or propofol (group P). Systemic inflammatory response syndrome (SIRS) occurrence was assessed at the end of the surgery and at the sixth, 12th, and 24th postoperative hours. Blood samples were obtained at 4 times: after anesthesia induction (T0), after release of the aortic cross-clamp (T1), at the end of the surgery (T2), and at the postoperative 24th hour (T3). The serum levels of interleukin 6 and tumor necrosis factor alpha, and the total antioxidant status (TAS) and total oxidant status, were analyzed. RESULTS SIRS was more common in group S than in group P at all times (p = 0.020, p = 0.036, p = 0.004, p = 0.008). There were no significant differences between the groups in the mean tumor necrosis factor alpha and interleukin 6 levels at any time. The TAS level at T2 was higher in group P than group S (p = 0.036). The serum TAS level increased at T2 compared with T0 in group P, but it decreased in group S (p = 0.041). CONCLUSION The results showed that propofol provided a greater antioxidant effect and reduced SIRS postoperatively more than sevoflurane in children with CCHD undergoing cardiac surgery.

Abstract
INTRODUCTION Status epilepticus is defined as the situation resulting from the failure of the mechanisms responsible for terminating an epileptic seizure. In 2015, an operational concept was adopted internationally in which two times are identified: a first time, at which treatment must begin (five minutes for convulsive status, 10-15 minutes for focal and non-convulsive status); and a second time, after which there is considered to be a high risk of subsequent sequelae (30 minutes in the case of the convulsive). It occurs in 3-42/100,000 children per year, who are refractory or super-refractory in 10-40% of cases. DEVELOPMENT This article will review the different therapeutic options for status, from early treatment at home to the different first-line (benzodiazepines), second-line (phenobarbital, valproic acid, phenytoin, levetiracetam and lacosamide) or third-line treatments, which include both pharmacological (anaesthetics, propofol, ketamine, lidocaine, topiramate, brivaracetam or perampanel) and non-pharmacological (ketogenic diet, immunomodulatory treatments or epilepsy surgery) therapies. CONCLUSIONS Early identification and treatment of a prolonged crisis are essential to prevent progression to status. Although with fewer sequelae than in adults, status epilepticus in children represents a cause of mortality of up to 3-5%, while 25% of them will develop subsequent epilepsy, as well as a considerable percentage of neurological sequelae.

Abstract
BACKGROUND Delirium is a commonly seen complication of cardiac surgery. Dexmedetomidine, by its anti-inflammatory properties and other effects, can attenuate postoperative delirium. AIMS The aim of this work was to study the incidence of delirium after coronary artery bypass graft surgery, and to compare the effects of dexmedetomidine and propofol on the incidence of postoperative delirium in coronary artery bypass graft surgery patients. MATERIALS AND METHODS A prospective, observational study was conducted on 180 consecutive patients undergoing off-pump or on-pump coronary artery bypass graft surgery. The patients were administered either intravenous dexmedetomidine (n = 90) or propofol (n = 90) after hemostasis was achieved, till they were ready for weaning from the ventilator. The Confusion Assessment Method was used to assess the incidence of postoperative delirium. MEASUREMENTS AND MAIN RESULTS A total of 25 (13.8%) patients developed delirium after coronary artery bypass graft surgery. Sedation with dexmedetomidine was associated with a significantly reduced incidence of postoperative delirium (8.9% v 18.9% propofol, P = 0.049). Subgroup analyses showed reduced incidence of postoperative delirium in off-pump patients compared to on-pump coronary artery bypass graft patients (3.3% vs. 20%, P = 0.009 dexmedetomidine group and 11.6% vs. 33.3%, P = 0.047 propofol group respectively). The mean age of the patients who had delirium was significantly more (64.9 ± 8.1 years vs. 52.5 ± 5.8 years, P = 0.046) compared to those who did not have delirium. CONCLUSION Administration of dexmedetomidine-based sedation resulted in the reduced incidence of postoperative delirium compared to propofol-based sedation in patients after coronary artery bypass graft surgery.

Abstract
BACKGROUND AND OBJECTIVES Status epilepticus that continues after the initial benzodiazepine and a second anticonvulsant medication is known as refractory status epilepticus (RSE). Management is highly variable because adequately powered clinical trials are missing. We aimed to determine whether propofol and midazolam were equally effective in controlling RSE in the intensive care unit, focusing on management in resource-limited settings. METHODS Patients with RSE treated with midazolam or propofol between January 2015 and December 2018 were retrospectively identified among 9 centers across 4 continents from upper-middle-income economies in Latin America and high-income economies in North America, Europe, and Asia. Demographics, Status Epilepticus Severity Score, etiology, treatment details, and discharge modified Rankin Scale (mRS) were collected. The primary outcome measure was good functional outcome defined as a mRS score of 0-2 at hospital discharge. RESULTS Three hundred eighty-seven episodes of RSE (386 patients) were included, with 162 (42%) from upper-middle-income and 225 (58%) from high-income economies. Three hundred six (79%) had acute and 79 (21%) remote etiologies. Initial RSE management included midazolam in 266 (69%) and propofol in 121 episodes (31%). Seventy episodes (26%) that were initially treated with midazolam and 42 (35%) with propofol required the addition of a second anesthetic to treat RSE. Baseline characteristics and outcomes of patients treated with midazolam or propofol were similar. Breakthrough (odds ratio [OR] 1.6, 95% CI 1.3-2.0) and withdrawal seizures (OR 2.0, 95% CI 1.7-2.5) were associated with an increased number of days requiring continuous intravenous anticonvulsant medications (cIV-ACMs). Prolonged EEG monitoring was associated with fewer days of cIV-ACMs (1-24 hours OR 0.5, 95% CI 0.2-0.9, and >24 hours OR 0.7, 95% CI 0.5-1.0; reference EEG <1 hour). This association was seen in both, high-income and upper-middle-income economies, but was particularly prominent in high-income countries. One hundred ten patients (28%) were dead, and 80 (21%) had good functional outcomes at hospital discharge. DISCUSSION Outcomes of patients with RSE managed in the intensive care unit with propofol or midazolam infusions are comparable. Prolonged EEG monitoring may allow physicians to decrease the duration of anesthetic infusions safely, but this will depend on the implementation of RSE management protocols. Goal-directed management approaches including EEG targets may hold promise for patients with RSE. CLASSIFICATION OF EVIDENCE This study provides Class III data that propofol and midazolam are equivalently efficacious for RSE.

Abstract
Most patients suffering from neoplastic diseases will at some point during their illness be approached surgically. Surgery itself may be unfortunately responsible for tumor proliferation and metastatic spread. With the perioperative period increasingly becoming a focus of research in anesthesia, anesthesiologists have looked at the chance to influence cancer progression based on their choice of anesthesia regimen and strategy. Many anesthetic agents have been investigated for their potential impact on the course of cancer disease. There is an abundance of retrospective studies and very few prospective ones that tackled this issue. The aim of this article is to review the current state of the evidence on general anesthesia involving volatile and intravenous agents as substrates, focusing on halogenated inhalational agents and propofol, to guide clinical decision making in assessments of the best practice for perioperative management of cancer surgery.

Abstract
The surgical stress responses, surgeries, and anesthetics used during surgeries have effects on post-surgery complications and metastasis. Volatile and/or intravenous anesthetics are generally used for cancer curative surgeries. Therefore, appropriate selection of anesthetics should be considered for better clinical outcomes. The objectives of the study were to compare postoperative complications, the overall survival, and recurrence-free survival of patients who had received volatile anesthesia against those of patients who had received propofol-based total intravenous anesthesia for digestive tract cancer curative surgeries. Patients had received propofol-based total intravenous anesthesia (PA cohort, n = 120) or volatile anesthesia (VA cohort, n = 185) for elective digestive tract cancer curative surgeries. Patients with age > 50 years (P = .0399), body mass index ≥ 25 kg/m2 (P = .0423), cancer stage III (P = .0041), and cancer stage IV (P = .0189) were operated through volatile anesthesia. Females (P = .0346), disable patients (P = .0479), patients with Charlson Comorbidity Index 2 (P = .0449), patients with cancer stage 0 or I (P = .0141), and patients with cancer stage II (P = .0289) were operated through propofol-based total intravenous anesthesia. Postoperative complication(s) between patients of both cohorts were statistically same (P = .9217). After 3-years of the follow-up period, a total of 81 (44%) patients from the VA cohort and 63 (52%) patients from the PA cohort survived irrespective of any kind of disease(s) (P = .9918). Also, a total of 53 (29%) patients from the VA cohort and 42 (35%) patients from the PA cohort survived without progression of cancer (P = .9981) after 3-years. Age > 50 years (P = 0.0491), Charlson Comorbidity Index ≥ 3 (P = 0.0481), and cancer stage > II (P = .0412) were independent parameters for death of patients suffering from digestive tract cancer due to any reason(s) during 3-years of the follow-up period after surgeries. The selection of anesthetic agents for cancer curative surgeries does not affect survival during 3-years of follow-up and postoperative complication(s) of patients suffering from digestive tract cancer (Level of Evidence: III; Technical Efficacy Stage: 4).

Abstract
INTRODUCTION Kidney biopsy is a procedure of choice for the diagnosis of many kidney diseases. In children it is performed with the use of sedatives. The aim of this study was to compare the combination of propofol/fentanyl with midazolam/ketamine for sedation in pediatric patients undergoing kidney biopsy. METHODS In this double-blinded clinical trial, seventeen children, candidate of kidney biopsy were included and randomized into two groups. One group received Midazolam/Ketamine with doses of 30 to 50 μg/kg and 0.25 to 1 mg/kg, and the other group were sedated with propofol/fentanyl combination in doses of 0.5 to 1 mg/kg and 0.5 to 1 mg/kg, respectively. Administration time, medication doses, total procedure time, need for analgesic use after the procedure, and patient relaxation, with no agitation during and after the biopsy were recorded. RESULTS Nine patients received midazolam/ketamine and eight received propofol/fentanyl. None of them experienced vomiting or itching after sedation. There were no meaningful differences in qualitative variables of the need for pain relief between two groups. Regarding the distribution of pain at the time of sedation, and 1, 3, 6, and 24 hours after sedation, there was no significant statistical difference between the two groups. There was also no significant statistical difference between the two groups, regarding patients' relaxation during, and 1, 3, 6, and 24 hours after biopsy. CONCLUSION There was no statistically significant difference between the degree of sedation and the analgesic effect of the two regimens in the two groups. DOI: 10.52547/ijkd.6982.

Abstract
Background and Objectives: Different types of anesthetics affect thermoregulatory mechanisms, such as the redistribution of body temperature, loss of skin heat, or inhibition of thermoregulatory vasoconstriction. Therefore, we compared remimazolam with propofol in terms of core body temperature in patients undergoing robotic-assisted and laparoscopic radical prostatectomy. Materials and methods: Ninety patients were randomly assigned to either the propofol−remifentanil (PR) group or the remimazolam−remifentanil (RR) group. The PR group (n = 45) received effect-site concentrations of 6.0 μg/mL of propofol and 4 ng/mL of remifentanil, followed by 0.9 mg/kg of 1% rocuronium and maintenance with effect-site concentrations of 2−4 μg/mL of propofol and 3 ng/mL of remifentanil. The RR group (n = 45) received remimazolam 6 mg/kg/h by continuous intravenous infusion and the effect-site concentration of 4 ng/mL of remifentanil, followed by 0.9 mg/kg of 1% rocuronium, remimazolam 1−3 mg/kg/h, and remifentanil 3 ng/mL. The primary outcome was core body temperature, and secondary outcomes included vasoconstriction threshold (°C) and time to onset of vasoconstriction (min). Results: The core body temperature in the RR group was significantly higher at 60, 80, 100, 120, 140, 160, and 180 min after induction than in the PR group (p < 0.01). The vasoconstriction threshold was significantly higher in the RR group (35.2 ± 0.4) than in the PR group (34.8 ± 0.3) (p < 0.01). The time to onset of vasoconstriction was significantly less in the RR group (150.5 ± 10.2) than in the PR group (158.5 ± 8.4) (p < 0.01). However, the incidence of intraoperative hypothermia was not significant between two groups. Conclusions: Remimazolam appears to reduce vasoconstriction threshold less than and had a faster onset of vasoconstriction, resulting in superior thermoregulatory control.

Abstract
BACKGROUND Percutaneous nephrolithotomy (PCNL) is the first-line and guideline-recommended treatment for large renal calculi. Multimodal analgesia (MMA) comprising a combination of different analgesics is an increasingly popular method for pain control as it has been shown to reduce postoperative pain and reduce opioid use and the risk of opioid misuse, with a shorter recovery time in various procedures and patient populations. OBJECTIVE In this study, we tested the hypothesis that MMA with propofol and sevoflurane (PS) can decrease pain intensity during surgery and used IoC2 as a real-time index of the analgesic effect of sevoflurane. STUDY DESIGN Prospective, single-center, double-blind, randomized controlled clinical trial. SETTING Xuanwu Hospital of Capital Medical University. METHODS Patients scheduled for elective percutaneous nephrolithotomy from January 2020 to July 2020 were randomized into 2 groups, standard multimodal analgesia (propofol + sevoflurane group) and control (propofol [P] group). The PS group received propofol 2.5 mg/kg/h along with 1% sevoflurane after induction for 30 minutes during the main anesthetic procedure, and the P group received propofol 5 mg/kg/h by intravenous infusion during the operation. Index of consciousness 2 (IoC2), namely nociception index, intraoperative hemodynamic fluctuation, bispectral index (BIS), electromyography, postanesthesia care unit (PACU) length of stay, visual analog scale (VAS) score, and Aldrete and Steward scores were recorded. RESULTS A total of 153 patients undergoing PCNL were enrolled. The demographic and clinical characteristics were similar between the 2 groups. IoC2 was reduced in the PS group compared to the P group at T10, T11, T12, T13, T14, and T15 time points, indicating that analgesia was more effective in the former. The BIS of the PS group did not differ significantly from that of the P group except at T12, T13, T14, and T15. PACU length of stay was shorter in the PS group than in the P group (mean [SD]: 54.35 [16.61] vs 47.39 [13.15], P = 0.04). VAS pain scores did not differ significantly between the 2 groups. CONCLUSION MMA with propofol and sevoflurane provided better analgesia than propofol alone and may be an effective method to reduce stress and the intraoperative nociceptive stimulus response in patients undergoing PCNL, thereby promoting rapid postoperative recovery.

Abstract
In order to explore the effects of propofol anesthesia system based on block chain on brain tissue and brain function protection, 88 patients undergoing craniocerebral trauma surgery are selected for prospective study. The anesthetic dose of propofol during operation in the control group is determined according to general information and personal situation. The team uses blockchain to process the patient's clinical data and general information to calculate the optimal dose of propofol. The changes of hemodynamic indexes of patients in the two groups are compared, including dural incision (T1), 1 h after craniotomy (T2), end of surgery (T3), and 6 h after surgery (T4). The changes of neuron-specific enolase (NSE) and central neuron-specific protein (S100β) at T1, T2, T3, and T4 in 2 groups are observed and recorded. The changes of malondialdehyde (MDA) at T1, T2, T3, and T4 are compared between the two groups. Based on the analysis of clinical data and general information of patients on blockchain, the optimal intraoperative anesthetic dose of propofol for patients can effectively protect the brain function of patients, and the intraoperative anesthesia state is relatively stable, and the changes and improvements of intraoperative indicators are good.

OBJECTIVES The aim of this study was to evaluate the efficacy of perioperative dexmedetomidine (DEX) combined with lidocaine intravenous infusion on relieving postoperative pain and improving recovery for patients undergoing thyroidectomy. MATERIALS AND METHODS A total of 138 patients undergoing thyroidectomy with general anesthesia were randomly divided into 4 groups: lidocaine (1.5 mg/kg bolus followed by 2 mg/kg/h infusion) in the group L, DEX (0.5 µg/kg) in the group D, lidocaine (same as the group L) with DEX (0.5 µg/kg) in the group L+D, and placebo as normal saline in the group C. All drugs were infused until the end of the surgery. The visual analog scale (VAS) scores of patients at 1, 4, 8, 12, and 24 hours following surgery, opioid requirement, propofol consumption, incidence of postoperative nausea and vomiting, awaking time, hemodynamic variables, and any adverse effects were assessed. RESULTS Compared with the group C, the VAS scores in the group L+D were significantly lower until 8 hours after surgery (P<0.05), while the VAS scores were significantly decreased just until 4 hours in the group L and 1 hour in the group D after surgery (P<0.05). There was no significant difference in opioid consumption between 4 groups. Propofol consumption in the group L+D was significantly lower than other groups (P<0.05). Compared with the group C, the incidence of postoperative nausea and vomiting in the group L+D was lower (P<0.05), and awaking time in the group L+D and the group L was shorter (P<0.05). CONCLUSION DEX combined with lidocaine infusion can effectively attenuate the postoperative pain without any serious adverse events, which may improve postoperative recovery in patients undergoing thyroidectomy.

OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:6298786. [PMID: 35087616 PMCID: PMC8789416 DOI: 10.1155/2022/6298786] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Accepted: 12/24/2021] [Indexed: 01/15/2023]
Abstract
BACKGROUND Hypoxia may induce mitochondrial abnormality, which is associated with a variety of clinical phenotypes in the central nervous system. Propofol is an anesthetic agent with neuroprotective property. We examined whether and how propofol protected hypoxia-induced mitochondrial abnormality in neurons. METHODS Primary rat hippocampal neurons were exposed to propofol followed by hypoxia treatment. Neuron viability, mitochondrial morphology, mitochondrial permeability transition pore (mPTP) opening, mitochondrial membrane potential (MMP), and adenosine triphosphate (ATP) production were measured. Mechanisms including reactive oxygen species (ROS), extracellular regulated protein kinase (ERK), protein kinase A (PKA), HIF-1α, Drp1, Fis1, Mfn1, Mfn2, and Opa1 were investigated. RESULTS Hypoxia increased intracellular ROS production and induced mPTP opening, while reducing ATP production, MMP values, and neuron viability. Hypoxia impaired mitochondrial dynamic balance by increasing mitochondrial fragmentation. Further, hypoxia induced the translocation of HIF-1α and increased the expression of Drp1, while having no effect on Fis1 expression. In addition, hypoxia induced the phosphorylation of ERK and Drp1ser616, while reducing the phosphorylation of PKA and Drp1ser637. Importantly, we demonstrated all these effects were attenuated by pretreatment of neurons with 50 μM propofol, antioxidant α-tocopherol, and ROS scavenger ebselen. Besides, hypoxia, propofol, α-tocopherol, or ebselen had no effect on the expression of Mfn1, Mfn2, and Opa1. CONCLUSIONS In rat hippocampal neurons, hypoxia induced oxidative stress, caused mitochondrial dynamic imbalance and malfunction, and reduced neuron viability. Propofol protected mitochondrial abnormality and neuron viability via antioxidant property, and the molecular mechanisms involved HIF-1α-mediated Drp1 expression and ERK/PKA-mediated Drp1 phosphorylation.

Abstract
Purpose Patients undergo dilatation and evacuation for abortion or miscarriage. However, bleeding is sometimes problematic. Despite reports on the association between volatile anesthetics and increased bleeding during the procedure, firm evidence is lacking. Therefore, we conducted a systematic review and meta-analysis to compare the effects of volatile anesthetics and propofol on the amount of bleeding in patients undergoing dilatation and evacuation. Methods We conducted a systematic search of four databases, namely PubMed, Embase, Cochrane Central Register of Controlled Trials databases, and Web of Science (Clarivate Analytics), from their respective inception to April 2021. Moreover, we searched two trial registration sites. The inclusion criterion was randomized controlled trials of patients who underwent dilatation and evacuation under general anesthesia using volatile anesthetics or propofol. The primary outcome was the amount of perioperative bleeding. The mean difference of the bleeding was combined using a random-effects model. The I2 statistic was used to assess heterogeneity. We assessed risk of bias with Cochrane domains. We controlled type I and II errors due to sparse data and repetitive testing with Trial Sequential Analysis. We assessed the quality of evidence with GRADE. Results Five studies were included in the systematic review. The amount of bleeding was compared in four studies and was higher in the volatile anesthetic group, with a mean difference of 164.7 ml (95% confidence interval, 43.6 to 285.7; p = 0.04). Heterogeneity was considerable, with an I2 value of 97%. Two studies evaluated the incidence of significant bleeding, which was significantly higher in the volatile anesthetic group (RR, 2.42; 95% confidence interval, 1.04–5.63; p = 0.04). Conclusion Choosing propofol over volatile anesthetics during dilatation and evacuation might reduce bleeding and the incidence of excessive bleeding. However, the quality of the evidence was very low. This necessitates further trials with a low risk of bias. Trial registration PROSPERO (CRD42019120873).

Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy and safety of sevoflurane-remifentanil (SR) vs propofol-remifentanil (PR) as inhalation anesthesia or total intravenous anesthesia in patients undergoing craniotomy, respectively. METHODS Electronic databases included PubMed, ScienceDirect, Embase, Cochrane library, CNKI, and Wanfang data were searched using suitable search items. Randomized clinical controlled trials comparing the combination of SR and PR as anesthetics for neurosurgery were included. The outcomes included wake-up time, spontaneous respiration time, extubation time, and safety. RESULTS Seventeen studies were included in this meta-analysis. There were no statistically significant differences in wake-up time (P = .25, standardized mean difference (SMD) = 0.29, 95% CI -0.20 to 0.77), extubation time (P = .1, SMD = 0.52, 95% CI -0.11 to 1.14) and spontaneous respiration time (P = .58, SMD = 0.43, 95% CI -1.07 to 1.93) when patients with SF and PF for anesthesia maintenance. Moreover, the changes of hemodynamic parameters are similar between the 2 groups. During anesthesia maintenance, SF could significantly increase the incidence of hypotension and brain edema than PF (P = .02, SMD = 1.68, 95% CI 1.07 to 2.62; P < .0001, SMD = 3.37, 95% CI 1.86 to 6.12), PF markedly promoted the incidence of hypertension (P = .001, SMD = 0.55, 95% CI 0.39 to 0.79). The postoperative adverse reactions were similar between the 2 groups (P > .05), but the incidence of postoperative nausea and vomiting proved to be higher in SF group (P < .0001, SMD = 2.12, 95% CI 1.47 to 3.07). CONCLUSIONS SR and PR as anesthetics in patients underwent craniotomy had similar effects, but PR was superior to SR in terms of safety of intraoperation and postoperation.

Abstract
BACKGROUND Remimazolam, a benzodiazepine ultra-short-acting sedative, has been used in general anesthesia since August 2020. It is used in awake surgeries that require awakening the patient in the middle of the surgery because of its rapid awakening effect as well as antagonistic interactions. If remimazolam has associated anterograde amnesia similar to benzodiazepines, it will have a positive effect on preventing psychological trauma. However, to our knowledge, the effect of remimazolam on anterograde amnesia has not been previously examined. METHODS/DESIGN The aim of this exploratory, open, propofol-controlled, single-center, randomized clinical trial is to examine the effect of remimazolam on postoperative memory retention and delayed regeneration. Seventy patients undergoing breast surgery will be included in the study. The patients will be randomly assigned to receive propofol or remimazolam as sedatives during surgery. The primary endpoint is the number of posters patients remember 24 hours after surgery (among 4 posters shown after awakening from anesthesia) as an assessment of anterograde amnesia. Secondary endpoints are retrograde amnesia, dose of analgesic given from the time the patient returns to the ward until 24 hours after surgery, immediate postoperative pain numerical rating scale scores, and pain numerical rating scale scores 24 hours after leaving the operating room. Recruitment will take place between October 2021 and March 2022 to achieve the target sample size. DISCUSSION To our knowledge, this is the first trial designed to examine the effects of remimazolam on postoperative memory retention and delayed regeneration in patients undergoing breast surgery. TRIAL REGISTRATION This clinical trial was registered at the University Hospital Medical Information Network (UMIN) Center on September 28, 2021 (UMIN-CTR: UMIN000045593).

Effects of inhalation and propofol anaesthesia on postoperative cognitive dysfunction in elderly noncardiac surgical patients: A systematic review and meta-analysis. Medicine (Baltimore) 2021; 100:e27668. [PMID: 34713863 PMCID: PMC8556046 DOI: 10.1097/md.0000000000027668] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Accepted: 10/12/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Postoperative cognitive dysfunction (POCD) is a very common event in elderly noncardiac surgical patients. The effects of inhalational anaesthetics and propofol on the incidence of POCD and postoperative cognitive status at different time points after surgery are currently unclear. METHODS We searched the Embase, Medline, Cochrane Library, and Web of Science databases for randomized controlled trials (RCTs), in which inhalation anaesthesia and propofol anaesthesia were compared. The incidence of POCD or postoperative cognitive status was assessed in elderly patients undergoing noncardiac surgery. RESULTS Fifteen RCTs with 1854 patients were included in this meta-analysis. The incidence of POCD on postoperative Days 2-6 after propofol anaesthesia was markedly lower than that after inhalation anaesthesia (risk ratio (RR): 0.37, 95% confidence interval (CI): 0.15-0.88, P = .025), and Mini-Mental State Examination (MMSE) scores after propofol anaesthesia were substantially higher than those after inhalation anaesthesia (standard mean difference (SMD): 0.59, 95% CI: 0.07-1.11, P = .026). The levels of interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were much lower after propofol anaesthesia than after inhalation anaesthesia (SMD: -2.027, 95% CI: -3.748- -0.307, P = .021; SMD: -0.68, 95% CI: -0.93- -0.43, P < .001). CONCLUSIONS The moderate evidence from this meta-analysis shows that, in elderly noncardiac surgical patients, propofol anaesthesia is superior to inhalation anaesthesia for attenuating of early POCD incidence, and low-level evidence shows that cognitive status is higher and systemic inflammation is less severe after propofol anaesthesia in the early days after surgery. LIMITATIONS The sample size was not sufficiently large for systemic inflammation, and the tools to identify POCD were not uniform in the included studies.

Abstract
BACKGROUND The specific mechanism of action of each anesthetic drug on the immune system is still incompletely known. It is important to know how the various anesthetics used in minimally invasive surgery (MIS) act on the inflammatory response because the choice of the anesthetic agent can influence the patient's immune system. AIM Evaluation of the effect of anesthetic drugs used for total intravenous anesthesia (Propofol and Midazolam) on the inflammatory response after minimally invasive gynecological surgery. PATIENTS, MATERIALS AND METHODS The inflammatory response in 20 female patients who underwent minimally invasive gynecological surgery under which intravenous anesthesia was performed. Depending on the combination of anesthetics used, we subdivided the study group into two groups, Group 1 consisting of the patients (n=10) who were given for total intravenous anesthesia, the combination with Midazolam+Fentanyl, and Group 2 (n=10) the patients who received the combination of Propofol+Fentanyl, respectively. Surgical interventional procedures included day surgery: diagnostic and operative hysteroscopy, endometrial ablation, surgical treatment of vulvar disorders. Serological profiling of patients was performed by dosing the serum concentration of nucleotide-binding domain (NOD) and leucine-rich repeat protein 3 (NLRP3) inflammasomes, interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), IL-10 before and two hours after the surgical procedure. RESULTS In our study, we found that in both groups of patients (Midazolam+Fentanyl - Group 1, Propofol+Fentanyl - Group 2), NLRP3 and cytokines concentrations in the serum were higher after MIS than those before MIS. CONCLUSIONS It appears that both Midazolam and Fentanyl and Propofol and Fentanyl have an immunomodulatory action due to the anti-inflammatory effect of both anesthetics. Therefore, anesthesiologists must choose an anesthetic method that uses individualized anesthetic agents, depending on the patient's immune status and disease.

Abstract
BACKGROUND Deep neuromuscular blockade is considered beneficial for improving the surgical space condition during laparoscopic surgery. Adequacy of the surgical space condition may affect the anesthetists' decision regarding titration of depth of anesthesia. We investigated whether deep neuromuscular blockade reduces the propofol requirement under bispectral index monitoring compared to moderate neuromuscular blockade. METHODS Adult patients undergoing elective laparoscopic colorectal surgery were randomly allocated to a moderate or deep group. A train-of-four count of 1-2 in the moderate group, and a post-tetanic count of 1-2 in the deep group, were maintained by continuous infusion of rocuronium. The induction and maintenance of anesthesia were achieved by target-controlled infusion of propofol and remifentanil. The dose of propofol was adjusted to maintain the bispectral index in the range of 40-50. The remifentanil dose was titrated to maintain the systolic blood pressure to within 20% of the ward values. RESULTS A total of 82 patients were included in the analyses. The mean±SD dose of propofol was 7.54 ± 1.66 and 7.42 ± 1.01 mg·kg-1·h-1 in the moderate and deep groups, respectively (P = .104). The mean±SD dose of remifentanil was 4.84 ± 1.74 and 4.79 ± 1.77 μg kg-1 h-1 in the moderate and deep groups, respectively (P = .688). In comparison to the moderate group, the deep group showed significantly lower rates of intraoperative patient movement (42.9% vs 22.5%, respectively, P = .050) and additional neuromuscular blocking agent administration (76% vs 53%, respectively, P = .007). Postoperative complications, including pulmonary complications, wound problems and reoperation, were not different between the two groups. CONCLUSION Deep neuromuscular blockade did not reduce the bispectral index-guided propofol requirement compared to moderate neuromuscular blockade during laparoscopic colon surgery, despite reducing movement of the patient and the requirement for a rescue neuromuscular blocking agent.

Abstract
Propofol (Pro) confers protection against renal ischemia/reperfusion (rI/R) injury through incompletely characterized mechanisms. Since Pro has shown net anti-inflammatory properties as part of its beneficial effects, we examined the potential role of Pro in the modulation of macrophage polarization status during both rI/R injury in vivo and exposure of cultured peritoneal macrophages (PMs) to hypoxia/reoxygenation (H/R). Rats were subjected to 45-min r/IR surgery or a sham procedure and administered PBS (vehicle) or Pro during the ischemia stage. Pro administration attenuated rI/R-induced kidney damage and renal TNF-α, IL-6, and CXCL-10 expression. Enhanced macrophage M2 polarization, evidenced by reduced iNOS and increased Arg1 and Mrc1 mRNA levels, was further detected after Pro treatment both in the kidney, after rI/R in vivo, and in H/R-treated PMs. Pro administration also repressed phosphorylated signal transducer and activator of transcription 1 (p-STAT1) and increased p-STAT3, p-STAT6, and peroxisome proliferator-activated receptor-γ (PPARγ) mRNA levels in H/R-exposed PMs. Importantly, siRNA-mediated PPARγ silencing repressed Pro-mediated STAT3 activation in PMs and restored proinflammatory cytokine levels and prevented macrophage M2 marker expression in both rI/R-treated rats and cultured PMs. These findings suggest that Pro confers renoprotection against rI/R by stimulating PPARγ/STAT3-dependent macrophage conversion to the M2 phenotype.

Abstract
BACKGROUND At present, liver cancer deaths of China account for about half of the global liver cancer deaths. The most common physiological change in anesthesia surgery for liver cancer is liver ischemia-reperfusion injury (LIRI). METHODS The Chinese and English medical databases were searched using a combination of the following search terms: "propofol", "liver cancer", "anesthesia surgery", and "ischemia reperfusion injury" in Chinese or English language, respectively. The articles taking patients received propofol intravenous anesthesia surgery for LIRI in the experimental group and patients received intravenous anesthesia with non-propofol drugs for LIRI in the control group were searched. Rev Man 5.3 software was used for meta-analysis. RESULTS A total of 18 articles were included, and most were considered to have low-risk bias (that is, medium- and high-quality publications). The meta-analysis results indicated that the superoxide dismutase (SOD) levels from the blockage of the hepatic hilum (B-HH) to the 15-minute opening of the hepatic hilum (O-HH) showed a mean deviation (MD) of -0.33 nU/mL and 95% confidential interval (CI) of -1.81 to 1.15 nmol/L (P<0.05). The levels of malondialdehyde (MDA) from B-HH to O-HH showed a MD of 1.80 nmol/L and 95% CI of 1.53 to 2.07 nmol/l (P<0.05). The MD of alanine transaminase (ALT) levels from B-HH to O-HH was 8.24 IU/L with 95% CI 6.43 to 10.06 IU/L (P<0.05). The MD of aspartate transaminase (AST) levels from B-HH to O-HH was -11.73 IU/L with 95% CI -14.04 to -9.43 IU/L (P<0.05). The RevMan5.3 software was used to draw the funnel chart for each indicator from B-HH to OHH. The results revealed that the circles in some articles were concentrated on the midline and were basically symmetrical with the midline, indicating that the research accuracy was high and there was no bias in publication. DISCUSSION This meta-analysis confirmed that propofol exerted a protective effect on LIRI during anesthesia surgery with hepatic hilar blockade.

Abstract
INTRODUCTION Malignant catatonia (MC) is a movement disorder syndrome characterized by immobility, rigidity, and consciousness disorders that develops in association with mental and physical diseases. It is often fatal due to hyperthermia, rhabdomyolysis, and acute kidney injury. Its clinical symptoms are similar to those of another disorder, neuroleptic malignant syndrome (NMS), and it is often difficult to distinguish between the 2 disorders. PATIENT CONCERNS An Asian woman in her 60s with history of schizophrenia. She was admitted to our hospital because of symptoms such as fever, unconsciousness, and muscle rigidity. Blood tests showed kidney injury and high creatinine kinase levels. DIAGNOSES At the time of admission, she had been diagnosed with NMS complicated by pulmonary aspergillosis and was undergoing treatment although there was no improvement. INTERVENTIONS Subsequently, the administration of propofol, a gamma-aminobutyric acid A agonist, markedly improved the symptoms, and the diagnosis was corrected to MC. At the beginning of her hospitalization, she received dantrolene, bromocriptine, amantadine, and L-3,4-dihydroxyphenylalanine as treatment for NMS, but her symptoms did not improve. With propofol, which is used for sedation, her catatonic symptoms improved markedly. Quetiapine administration further improved the symptoms, and it eventually resolved completely. OUTCOMES The patient's MC was in remission. Prolonged intensive care management resulted in a decline in activities of daily living, and she required rehabilitation at another hospital. CONCLUSION This is the first report of MC with suspected involvement of pulmonary aspergillosis. MC differs from NMS, in that it is treated more effectively with gamma-aminobutyric acid A agonists. Although benzodiazepines are the first choice for the diagnosis and treatment of MC, they are ineffective for majority of patients with schizophrenia. However, even in such cases, propofol and quetiapine are effective, and they facilitate diagnosis and treatment.

Abstract
This study attempted to investigate the effect of intravenous anesthesia with dexmedetomidine and propofol combined with seaweed polysaccharides on painless induced abortion. A total of 82 pregnant females were divided into study group and reference group. The subjects in the study group took seaweed polysaccharides orally before surgery and received intravenous anesthesia with dexmedetomidine and propofol, while the subjects in the reference group received intravenous anesthesia with sufentanil combined with propofol. The onset time of anesthesia in the reference group was significantly shorter than that in the study group (P<0.001) and both recovery time and the dosage of propofol in the study group were significantly lower than those in the reference group (P<0.001). The values of MAP and HR at T3 and T4, clinical analgesia effective rate, ramsay sedation scores and incidence of adverse reactions of the subjects in study group was significantly better than those indexes of the subjects in reference group (P<0.05). The intravenous anesthesia with dexmedetomidine and propofol combined with seaweed polysaccharides is a promising strategy for painless induced abortion, which is worthy of application and popularization in clinical practice.
