Characteristics associated with effectiveness in postoperative delirium research: a systematic review of randomised controlled trials with meta-regression and meta-analysis. Br J Anaesth 2024:S0007-0912(24)00349-0. [PMID: 38969535 DOI: 10.1016/j.bja.2024.05.033] [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: 09/15/2023] [Revised: 05/28/2024] [Accepted: 05/30/2024] [Indexed: 07/07/2024] Open
Abstract
BACKGROUND Postoperative delirium remains prevalent despite extensive research through randomised trials aimed at reducing its incidence. Understanding trial characteristics associated with interventions' effectiveness facilitates data interpretation. METHODS Trial characteristics were extracted from eligible trials identified through two systematic literature searches. Multivariable meta-regression was used to investigate trial characteristics associated with effectiveness estimated using odds ratios. Meta-analysis was used to investigate pooled effectiveness. RESULTS We identified 201 eligible trials. Compared with China, trials from the USA/Canada (ratio of odds ratio, 1.89; 95% confidence interval, 1.45-2.45) and Europe/Australia/New Zealand (1.67; 1.29-2.18) had an 89% and 67% higher odds ratio, respectively, suggesting reduced effectiveness. The effectiveness was enhanced when the incidence of postoperative delirium increased (0.85; 0.79-0.92, per 10% increase). Trials with concerns related to deviations from intended interventions reported increased effectiveness compared with those at low risk (0.69; 0.53-0.90). Compared with usual care, certain interventions appeared to have reduced the incidence of postoperative delirium in low-risk trials with low-to-moderate certainty of evidence. However, these findings should be considered inconclusive because of challenges in grouping heterogeneous interventions, the limited number of eligible trials, the prevalence of small-scale studies, and potential publication bias. CONCLUSIONS The effectiveness of postoperative delirium trials varied based on the region of trial origin, the incidence of delirium, and the risk of bias. The limitations caution against drawing definitive conclusions from different bodies of evidence. These findings highlight the imperative need to improve the quality of research on a global scale.

Abstract
Objective To investigate the effects of intraoperative intravenous administration of dexmedetomidine (DEX) on the recovery quality of donors undergoing pure laparoscopic donor hepatectomy. Methods A total of 56 liver donors who were going to undergo scheduled pure laparoscopic donor hepatectomy were enrolled and randomly assigned to two groups, a DEX group ( n=28) and a control group ( n=28). Donors in the DEX group received DEX infusion at a dose of 1 μg/kg over 15 minutes through a continuous pump, which was followed by DEX at 0.4 μg/(kg·h) until the disconnection of the portal branch. Donors in the control group were given an equal volume of 0.9% normal saline at the same infusion rate and over the same period of time as those of the dex infusion in the DEX group. The primary outcome was the incidence of emergence agitation (EA). The Aono's Four-point Scale (AFPS) score was used to assess EA. The secondary observation indicators included intraoperative anesthesia and surgery conditions, spontaneous respiration recovery time, recovery time, extubation time, scores for the Ramsay Sedation Scale, the incidence of chills, numeric rating scale (NRS) score for pain, and blood pressure and heart rate after extubation. Results The incidence of EA was 10.7% and 39.3% in the DEX group and the control group, respectively, and the incidence of EA was significantly lower in the DEX group than that in the control group ( P=0.014). The APFS scores after extubation in the DEX group were lower than those in the control group (1 [1, 1] vs. 2 [1, 3], P=0.005). Compared to the control group, the dosages of intraoperative propofol and remifentanil were significantly reduced in the DEX group ( P<0.05). During the recovery period, the number of donors requiring additional boluses of analgesia, the blood pressure, and the heart rate were all lower in the DEX group than those in the control group ( P<0.05). No significant differences between the two groups were observed in the spontaneous respiration recovery time, recovery time, extubation time, the incidence of chills, NRS score, scores for the Ramsay Sedation Scale, and the length-of-stay in postanesthesia care unit (PACU) ( P>0.05). Conclusion DEX can reduce the incidence of EA after pure laparoscopic donor hepatectomy and improve the quality of recovery without prolonging postoperative recovery time or extubation time.

Wang D, Liu Z, Zhang W, Zu G, Tao H, Bi C. Intravenous infusion of dexmedetomidine during the surgery to prevent postoperative delirium and postoperative cognitive dysfunction undergoing non-cardiac surgery: a meta-analysis of randomized controlled trials. Eur J Med Res 2024; 29:239. [PMID: 38637853 PMCID: PMC11025279 DOI: 10.1186/s40001-024-01838-z] [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: 03/18/2023] [Accepted: 04/10/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Dexmedetomidine plays a pivotal role in mitigating postoperative delirium and cognitive dysfunction while enhancing the overall quality of life among surgical patients. Nevertheless, the influence of dexmedetomidine on such complications in various anaesthesia techniques remains inadequately explored. As such, in the present study, a meta-analysis was conducted to comprehensively evaluate its effects on postoperative delirium and cognitive dysfunction. METHODS A number of databases were searched for randomised controlled trials comparing intravenous dexmedetomidine to other interventions in preventing postoperative delirium and cognitive dysfunction in non-cardiac and non-neurosurgical patients. These databases included PubMed, Embase, and Cochrane Library. Statistical analysis and graphing were performed using Review Manager, STATA, the second version of the Cochrane risk-of-bias tool for randomised controlled trials, and GRADE profiler. MAIN RESULTS This meta-analysis comprised a total of 24 randomised controlled trials, including 20 trials assessing postoperative delirium and 6 trials assessing postoperative cognitive dysfunction. Across these 24 studies, a statistically significant positive association was observed between intravenous administration of dexmedetomidine and a reduced incidence of postoperative delirium (RR: 0.55; 95% CI 0.47 to 0.64, p < 0.00001, I2 = 2%) and postoperative cognitive dysfunction (RR: 0.60; 95% CI 0.38 to 0.96, p = 0.03, I2 = 60%). Subgroup analysis did not reveal a significant difference in the incidence of postoperative delirium between the general anaesthesia and non-general anaesthesia groups, but a significant difference was observed in the incidence of postoperative cognitive dysfunction. Nonetheless, when the data were pooled, it was evident that the utilisation of dexmedetomidine was associated with an increased incidence of hypotension (RR: 1.42; 95% CI 1.08 to 1.86, p = 0.01, I2 = 0%) and bradycardia (RR: 1.66; 95% CI 1.23 to 2.26, p = 0.001, I2 = 0%) compared with other interventions. However, there was no significantly higher occurrence of hypertension in the DEX groups (RR = 1.35, 95% CI 0.81-2.24, p = 0.25, I2 = 0%). CONCLUSION Compared with other interventions, intravenous dexmedetomidine infusion during non-cardiac and non-neurosurgical procedures may significantly reduce the risk of postoperative delirium and cognitive dysfunction. The results of subgroup analysis reveal a consistent preventive effect on postoperative delirium in both general and non-general anaesthesia groups. Meanwhile, continuous infusion during general anaesthesia was more effective in reducing the risk of cognitive dysfunction. Despite such findings, hypotension and bradycardia were more frequent in patients who received dexmedetomidine during surgery.

Abstract
Cancer is a leading cause of death worldwide. With the increasingly aging population, the number of emerging cancer cases is expected to increase markedly in the foreseeable future. Surgical resection with adjuvant therapy is the best available option for the potential cure of many solid tumors; thus, approximately 80% of patients with cancer undergo at least one surgical procedure during their disease. Agents used in general anesthesia can modulate cytokine release, transcription factors, and/or oncogenes. This can affect host immunity and the capability of cancer cells to survive and migrate, not only during surgery but for up to several weeks after surgery. However, it remains unknown whether exposure to anesthetic agents affects cancer recurrence or metastasis. This review explores the current literature to explain whether and how the choice of anesthetic and perioperative medication affect cancer surgery outcomes.

Abstract
Dexmedetomidine (DEX) is a highly selective α2-adrenoceptor agonist that is widely used in intensive and anesthetic care for its sedative and anxiolytic properties. DEX has the capacity to alleviate inflammatory pain while limiting immunosuppressive glucocorticoid stress during major surgery, thus harboring therapeutic benefits for oncological procedures. Recently, the molecular mechanisms of DEX-mediated anticancer effects have been partially deciphered. Together with additional preclinical data, these mechanistic insights support the hypothesis that DEX-induced therapeutic benefits are mediated via the stimulation of adaptive anti-tumor immune responses. Similarly, published clinical trials including ancillary studies described an immunostimulatory role of DEX during the perioperative period of cancer surgery. The impact of DEX on long-term patient survival remains elusive. Nevertheless, DEX-mediated immunostimulation offers an interesting therapeutic option for onco-anesthesia. Our present review comprehensively summarizes data from preclinical and clinical studies as well as from ongoing trials with a distinct focus on the role of DEX in overcoming (tumor microenvironment (TME)-imposed) cancer therapy resistance. The objective of this update is to guide clinicians in their choice toward immunostimulatory onco-anesthetic agents that have the capacity to improve disease outcome.

Abstract
Background Emergence agitation (EA) is one of the most common complications in clinical general anesthesia during recovery in adults. Remifentanil and propofol can reduce the incidence of EA, but with no randomized controlled trial to evaluate their effectiveness for treating EA. This study aims to compare the effectiveness of remifentanil and propofol for treating EA following general anesthesia. Patients and methods Among 152 randomized patients with a mean of 49.5 years, and 99 (65.1%) of them being male, 149 were divided into two groups for subsequent analysis. The remifentanil group (Group R, n = 74) received a 0.5μg kg-1 remifentanil infusion followed by a 0.05μg kg-1 min-1 infusion until 15 minutes, after the onset of agitation. The propofol group (Group P, n = 75) received a 1mg kg-1 propofol infusion once agitation occurred. Emergence agitation was assessed using the Riker Sedation Agitation Score, with a score of ≥5 defining emergence agitation. During the post-anesthesia care unit (PACU), the recurrence of emergence agitation, time to extubation, and discharge from PACU were evaluated. Results The incidence of reoccurring emergence agitation was lower in Group R (29.7%) compared with Group P (49.3%), with an odds ratio of 0.44 (95% CI 0.22-0.85; P=0.014). The time to extubation was shorter in Group R (mean 12min, range 8-15 min) compared with Group P (mean 17min, range 13-21 min) (P<0.001), as was the time discharge from the PACU (mean 30.5 min, range 25-40 min) vs Group P (mean 37.5 min, range 31-50 min) (P=0.001). Conclusion Treatment of emergence agitation in adults with remifentanil infusion is more effective than propofol, with a shorter time to extubation and discharge from PACU.

Abstract
Postoperative delirium (POD) remains a common, dangerous and resource-consuming adverse event but is often preventable. The whole peri-operative team can play a key role in its management. This update to the 2017 ESAIC Guideline on the prevention of POD is evidence-based and consensus-based and considers the literature between 01 April 2015, and 28 February 2022. The search terms of the broad literature search were identical to those used in the first version of the guideline published in 2017. POD was defined in accordance with the DSM-5 criteria. POD had to be measured with a validated POD screening tool, at least once per day for at least 3 days starting in the recovery room or postanaesthesia care unit on the day of surgery or, at latest, on postoperative day 1. Recent literature confirmed the pathogenic role of surgery-induced inflammation, and this concept reinforces the positive role of multicomponent strategies aimed to reduce the surgical stress response. Although some putative precipitating risk factors are not modifiable (length of surgery, surgical site), others (such as depth of anaesthesia, appropriate analgesia and haemodynamic stability) are under the control of the anaesthesiologists. Multicomponent preoperative, intra-operative and postoperative preventive measures showed potential to reduce the incidence and duration of POD, confirming the pivotal role of a comprehensive and team-based approach to improve patients' clinical and functional status.

Abstract
OBJECTIVE Review dexmedetomidine use in critically ill patients for niche indications including sleep, delirium, alcohol withdrawal, sepsis, and immunomodulation. DATA SOURCES Literature was sought using PubMed (February 2012-November 2022). Search terms included dexmedetomidine AND (hypnotics OR sedatives OR sleep OR delirium OR immunomodulation OR sepsis OR alcohol withdrawal). STUDY SELECTION AND DATA EXTRACTION Relevant studies conducted in humans ≥18 years published in English were included. Exclusion criteria included systematic reviews, meta-analyses, and studies evaluating oral dexmedetomidine or other alpha-2 agonists. DATA SYNTHESIS A total of 231 articles were retrieved. After removal of duplicates, title and abstract screening, and application of inclusion criteria, 35 articles were included. Across the clinical conditions included in this review, varying clinical outcomes were seen. Dexmedetomidine may improve morbidity outcomes in delirium, sleep, and alcohol withdrawal syndrome. Due to limited human studies and poor quality of evidence, no conclusions can be drawn regarding the role of dexmedetomidine in immunomodulation or sepsis. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE This review presents data for potential niche roles of dexmedetomidine aside from sedation in critically ill patients. This may serve as a guide for sedation selection in critically ill patients who may also benefit from the pleiotropic effects of dexmedetomidine due to a clinical condition discussed in this review. CONCLUSION While further studies are needed, dexmedetomidine may provide benefit in other indications in critically ill patients including delirium, sleep, and alcohol withdrawal. Given the poor quality of evidence of dexmedetomidine use in immunomodulation and sepsis, no conclusions can be drawn.

[PMID: 36702780 DOI: 10.1111/aas.14208] [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: 09/13/2022] [Revised: 01/18/2023] [Accepted: 01/20/2023] [Indexed: 01/28/2023]
Abstract
OBJECTIVES To assess any benefit or harm, we conducted a systematic review of randomised clinical trials (RCTs) allocating adults to dexmedetomidine versus placebo/no intervention for the prevention of delirium in intensive care or post-operative care units. DATA SOURCES We searched Medline, Embase, CENTRAL and other databases. The last search was 9 April 2022. DATA EXTRACTION Literature screening, data extraction and risk of bias volume 2 assessments were performed independently and in duplicate. Primary outcomes were occurrences of serious adverse events (SAEs), delirium and all-cause mortality. We used meta-analysis, Trial Sequential Analysis, and GRADE (Grading Recommendations Assessment, Development and Evaluation). DATA SYNTHESIS Eighty-one RCTs (15,745 patients) provided data for our primary outcomes. Results from trials at low risk of bias showed that dexmedetomidine may reduce the occurrence of the most frequently reported SAEs (relative risk [RR] 0.69; 95% CI 0.43-1.09), cumulated SAEs (RR 0.70; 95% CI 0.52-0.95) and the occurrence of delirium (RR 0.62; 95% CI 0.43-0.89). The certainty of evidence was very low for delirium. Mortality was very low in trials at low risk of bias (0.4% in the dexmedetomidine groups and 1.0% in the control groups) and meta-analysis did not provide conclusive evidence that dexmedetomidine may result in lower or higher all-cause mortality (RR 0.47; 95% CI 0.18-1.21). There was a lack of information from trial results at low risk of bias for all primary outcomes. CONCLUSIONS Trial results at low risk of bias showed that dexmedetomidine might reduce occurrences of SAEs and delirium, while no conclusive evidence was found for effects on all-cause mortality. The certainty of evidence ranged from very low for occurrence of delirium to low for the remaining outcomes.

Abstract
Dexmedetomidine might reduce delirium after cardiac surgery. We allocated 326 participants to an infusion of dexmedetomidine at a rate of 0.6 μg kg-1 for 10 min and then at 0.4 μg.kg-1 .h-1 until the end of surgery; 326 control participants received comparable volumes of saline. We detected delirium in 98/652 (15%) participants during the first seven postoperative days: 47/326 after dexmedetomidine vs. 51/326 after placebo, p = 0.62, adjusted relative risk (95%CI) 0.86 (0.56-1.33), p = 0.51. Postoperative renal impairment (Kidney Disease Improving Global Outcomes stages 1, 2 and 3) was detected in 46, 9 and 2 participants after dexmedetomidine and 25, 7 and 4 control participants, p = 0.040. Intra-operative dexmedetomidine infusion did not reduce the incidence of delirium after cardiac valve surgery but might impair renal function.

Abstract
BACKGROUND Delirium is common, especially after neurosurgery. Dexmedetomidine might reduce delirium by improving postoperative analgesia and sleep quality. We tested the primary hypothesis that dexmedetomidine administration during intracerebral tumour resection reduces the incidence of postoperative delirium. METHODS This randomised, double-blind, placebo-controlled trial was conducted in two tertiary-care hospitals in Beijing. We randomised 260 qualifying patients to either dexmedetomidine (n=130) or placebo (n=130). Subjects assigned to dexmedetomidine were given a loading dose of 0.6 μg kg-1 followed by continuous infusion at 0.4 μg kg-1 h-1 until dural closure; subjects in the placebo group were given comparable volumes of normal saline. The primary outcome was the incidence of delirium, which was assessed with the Confusion Assessment Method twice daily during the initial 5 postoperative days. RESULTS The average (standard deviation) age of participating patients was 45 (12) yr, duration of surgery was 4.2 (1.5) h, and patients assigned to dexmedetomidine were given an average of 126 (45) μg of dexmedetomidine. There was less delirium during the initial 5 postoperative days in patients assigned to dexmedetomidine (22%, 28 of 130 patients) than in those given placebo (46%, 60 of 130 patients) with a risk ratio of 0.51 (95% confidence interval: 0.36-0.74, P<0.001). Postoperative pain scores with movement, and recovery and sleep quality were improved by dexmedetomidine (P<0.001). The incidence of safety outcomes was similar in each group. CONCLUSIONS Prophylactic intraoperative dexmedetomidine infusion reduced by half the incidence of delirium during the initial 5 postoperative days in patients recovering from elective brain tumour resection.

The Effectiveness of Dexmedetomidine as a Prophylactic Treatment for Emergence Delirium Among Combat Veterans With High Anxiety: A Randomized Placebo-Controlled Trial. Mil Med 2023; 188:e286-e294. [PMID: 34057183 DOI: 10.1093/milmed/usab212] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Revised: 04/23/2021] [Accepted: 05/25/2021] [Indexed: 01/11/2023] Open
Abstract
INTRODUCTION Emergence delirium (ED) is characterized by agitation, confusion, and violent physical and verbal behavior associated with awakening from general anesthesia. Combat exposure among U.S. military veterans has been identified as a risk factor for ED. Preoperative baseline anxiety was shown to be a predictor of ED, and combat veterans are known to be at high risk for anxiety as well as depression and PTSD. Dexmedetomidine is an alpha-2 receptor agonist proven to mitigate ED in several patient populations. Perioperative use of dexmedetomidine demonstrated promising benefits in pediatric ED but has not been evaluated in combat veterans. MATERIALS AND METHODS This study was a multi-site, prospective, randomized controlled investigation of 369 patients with a history of military combat exposure who were scheduled for elective surgery with a general anesthetic as the primary means of anesthesia. The trial was funded by the Tri-Service Nursing Research Program Grant HU0001-14-TS05 (N14-PO3) and approved by the Institutional Review Boards at the Naval Medical Center San Diego, Womack Army Medical Center, Walter Reed National Military Medical Center, and the Uniformed Services University of the Health Sciences, Bethesda, MD. All subjects were administered the State-Trait Anxiety Inventory (STAI) to evaluate baseline anxiety. Those enrolled subjects with a low anxiety level (STAI < 39) (n = 215) were placed in the observational arm of the study. Those with a high anxiety level (STAI ≥ 39) were placed in the experimental arm (n = 153) and were further randomized to treatment with intraoperative dexmedetomidine infusion (1 μg/kg bolus at induction, followed by a 0.6 μg/kg/h infusion continued until emergence) (n = 75) or a placebo intraoperative infusion (n = 75). Following the delivery of the prescribed anesthetic, all subjects were observed for signs of ED using the Pediatric Anesthesia Emergence Delirium (PAED) Scale. The patient and data recorder remained blinded to the randomization results. RESULTS The central tendencies of demographics and clinical characteristics are reported. PAED among those randomized to dexmedetomidine (median 7, interquartile interval (IQI) 5.2-9.2) tended to be less (P < .0001) than that of those randomized to control (median 12, IQI 10-13). Dexmedetomidine was found to be the most important predictor of PAED (35% relative importance), followed by Patient Health Questionnaire (14%), STAI-Trait (9%), and PTSD Checklist-Military Version (8%); the overall rankings are featured. Randomization to receipt of dexmedetomidine was associated with a 3.7-unit reduction (95% CI 2.5-4.9) in PAED (P < .001) in a linear model controlling for several variables, and the directionality of the effect persisted upon regularization in a penalized linear model. CONCLUSIONS Dexmedetomidine was effective at reducing PAED among combat veterans who were experiencing symptoms of pre-operative anxiety (i.e., STAI-State ≥39). Although psychological morbidity is not unique to the military population, combat veterans carry some of the highest rates of anxiety, PTSD and depression compared to the general population. Dexmedetomidine can be safety employed by anesthesia providers to reduce symptoms of ED in the perioperative period. The double-blind randomized, controlled study design strengthens our analyses; however, this study did not control for the type of surgical procedure or the duration of anesthetic. Furthermore, we only enrolled patients with combat exposure experiencing symptoms of anxiety and did not investigate the role of dexmedetomidine in combat veterans with less anxiety. Further study of the relationship between psychological comorbidities, ED, and dexmedetomidine is warranted.

Abstract
Postoperative cognitive dysfunction (POCD) is a common neurological system disorder in surgical patients. The choice of anesthetic can potentially reduce POCD. The authors performed this network meta-analysis to compare different anesthetic drugs in reducing the incidence of POCD for elderly people undergoing noncardiac surgery. We searched MEDLINE, EMBASE, the Cochrane Library, and the Web of Science for randomized controlled trials comparing the different anesthetic drugs for noncardiac surgery in elderly from inception until July, 2022. The protocol was registered on the PROSPERO database (CRD#42020183014). A total of 34 trials involving 4314 patients undergoing noncardiac surgery in elderly were included. The incidence of POCD for each anesthetic drug was placebo (27.7%), dexmedetomidine (12.9%), ketamine (15.2%), propofol (16.8%), fentanyl (23.9%), midazolam (11.3%), sufentanil (6.3%), sevoflurane (24.0%), and desflurane (28.3%). Pairwise and network meta-analysis showed dexmedetomidine was significantly reducing the incidence of POCD when compared with placebo. Network meta-analysis also suggested dexmedetomidine was significantly reducing the incidence of POCD when compared with sevoflurane. Sufentanil and dexmedetomidine ranked the first and second in reducing the incidence of POCD with the surface under the cumulative ranking curve value of 87.4 and 81.5%. Sufentanil and dexmedetomidine had the greatest possibility to reduce the incidence of POCD for elderly people undergoing noncardiac surgery.

Abstract
Background The incidence of postoperative delirium (POD) is high in elderly patients with one-lung ventilation, which is mostly related to the impairment of cerebral oxygen supply/demand balance during operation. (Surgical) stress can cause changes to normal physiological function and increase oxygen supply to the brain. When cerebral oxygen supply/demand is unbalanced, other organs may have already suffered from hypoperfusion or even hypoxic damages leading to increased release of inflammatory factors. Regional saturation of cerebral oxygenation (rScO2) monitoring can noninvasively monitor the variation of regional cerebral oxygen supply/demand balance in real time, and it has a good correlation with the occurrence of POD. S-100β is one of the markers commonly used to predict and diagnose POD, and lactate is one of the important indicators for the quality of tissue perfusion. The study explores whether the goal-directed therapy based on rScO2 monitoring can reduce perioperative inflammatory factor levels and POD incidence in elderly patients with one-lung ventilation and improve tissue perfusion. Methods The study is registered on Chinese Clinical Trial Registry (ChiCTR2100054888). A total of 159 patients scheduled for thoracoscopic lobectomy under general anesthesia were divided into the control group (n = 81) and the goal-directed therapy group (GDT group, n = 78). On the basis of the conventional management in the control group, the GDT group applied goal-directed rScO2 monitoring to maintain rScO2 at ±20% baseline level during one-lung ventilation. The levels of interleukin-1β, interleukin-6, tumor necrosis factor-α, and lactate; the intensity of postoperative pain; and the incidence of POD before anesthesia (T1), at the end of operation (T2), on day 1 after operation (T3), on day 3 after operation (T4), and on day 7 after operation or before discharge (T5) were compared respectively between the two groups. Results The incidence of POD at T3 and the awakening time in the GDT group were lower than those in the control group (P < 0.05). During T2 to T4, the levels of inflammatory factors and lactate concentration in the control group were higher than those in the GDT group (P < 0.05). During T3 to T4, the levels of C-reactive protein and lactate in the control group were higher than those in the GDT group (P < 0.05). During T2 to T3, the levels of S-100β in the control group were higher than those in the GDT group (P < 0.05). The levels of inflammatory factors and lactate concentration in both groups during T2 to T4 were higher than those at T1 and T5 (P < 0.05), and there was no statistical difference at T1 versus T5 (P > 0.05). There was no significant difference in postoperative pain intensity, the incidence of agitation during awakening, and postoperative hospital stays between the two groups. Conclusion Goal-directed therapy based on rScO2 monitoring can reduce perioperative inflammatory factor levels, postoperative delirium incidence, and postoperative awakening time and improve tissue perfusion in elderly patients with one-lung ventilation.

Abstract
Delirium is defined by the DSM-5 as a fluctuating course of disturbance in attention, cognition, and awareness that develops over a short period without any pre-existing neurocognitive disorder. As people age, there is an increased risk of complications that may occur following a surgical procedure and one such acute complication is delirium. Studies are emerging to reduce the incidence of postoperative delirium, and one such preventive measures implemented in recent years include the administration of dexmedetomidine, a high selectivity α-2 adrenoceptor agonist. This study aims to review the efficacy of Dexmedetomidine in the prevention of postoperative delirium in randomized controlled trials in patients older than 18 years of age. The literature was explored in three online databases, namely, PubMed, Science Direct, and Scopus. Appropriate keywords and MesH terms were employed to scrutinize relevant articles that demonstrated the effects of dexmedetomidine in the prevention of postoperative delirium. The data was restricted to randomized controlled trials and clinical trials published from 2017 to 2021 in human patients older than >18 years of age undergoing non-cardiac-related procedures. The randomized clinical trials were critically assessed with the Cochrane risk of bias tool. We proceeded to screen 428 records with the assessment of the PRISMA chart and filtered out 420 papers to obtain a total of eight studies where we identified data such as sample size, types of surgeries in which the patients were involved, the delirium assessment tool, the plan of the administration of dexmedetomidine and the outcomes evaluated in each study. The Confusion Assessment Method (CAM) was the prevailing assessment tool used with the sole purpose to evaluate the incidence of postoperative delirium as the primary outcome, and assessment of inflammatory cytokines, sleep quality, and pain scales were considered as secondary outcomes. The dosage of dexmedetomidine varied among studies, and it displayed varying impacts on postoperative delirium and the secondary outcomes as well. Limitations include varying ages and ethnicities of the population. It was concluded that dexmedetomidine prevents the development of postoperative delirium in elderly patients undergoing non-cardiac surgical interventions by modulating important predisposing factors such as neuroinflammation, pain, and sleep quality. No funding was made for this study.

Abstract
Introduction The efficacy of dexmedetomidine supplementation for thoracoscopic surgery remains controversial. We conduct a systematic review and meta-analysis to explore the impact of dexmedetomidine for thoracoscopic surgery. Methods We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2020 for randomized controlled trials (RCTs) assessing the effect of dexmedetomidine supplementation on thoracoscopic surgery. This meta-analysis is performed using the random-effect model. Results Six RCTs involving 510 patients are included in the meta-analysis. Overall, compared with control group for thoracoscopic surgery, dexmedetomidine supplementation results in significantly reduced pain scores (SMD = − 1.50; 95% CI = − 2.63–− 0.37; P = 0.009), anesthetic consumption (SMD = − 3.91; 95% CI = − 6.76–− 1.05; P = 0.007), mean heart rate (SMD = − 0.41; 95% CI = − 0.65–− 0.18; P = 0.0007), and the risk ratio (RR) of ICU stay (RR = 0.39; 95% CI = 0.19–0.80; P = 0.01), but showed no obvious effect on mean blood pressure (SMD = − 0.07; 95% CI = − 0.45–0.31; P = 0.72) or hospital stay (SMD = − 0.61; 95% CI = − 1.30–0.08; P = 0.08). Conclusions Dexmedetomidine supplementation can substantially improve the analgesic efficacy for thoracoscopic surgery.

Abstract
OBJECTIVE To clarify the effect of an intraoperative low-dose dexmedetomidine infusion on emergence agitation following general anaesthesia in elderly patients. METHODS Eighty elderly patients (> 64-years-old) following elective general anaesthesia for radical cancer surgeries were randomly allocated into two groups (n = 40 each): the dexmedetomidine group (Group D) and the normal saline group (Group C). Anaesthesia was maintained with continuous intravenous infusion of dexmedetomidine at - 0.2 µg kg-1 h-1 in Group D, and an equal volume of normal saline (0.5 ml kg-1 h-1) was given in Group C. All patients were observed for 30 min in the post-anaesthesia care unit (PACU), AFPS and NRS were recorded every 2 min, and the total doses of nalbuphine and fentanyl were calculated in the PACU. MAP and HR were recorded at the time of 10 min (T1), 20 min (T2), 30 min (T3) after dexmedetomidine or saline pumping, and before extubation (T4), immediately after extubation (T5), and 5 min after extubation (T6). We also documented some durations, including anaesthesia duration (D1), surgery duration (D2), duration from the end of surgery to extubation (D3), and emergence agitation duration (D4). RESULTS The MAP in Group C was significantly higher than that in Group D (P < 0.05), and there were no significant changes between the two groups in HR and MAP within each time point and D1, D2, D3, and D4. The incidence of agitation, NRS score and total dose of nalbuphine and fentanyl were all lower in Group D than in Group C (P < 0.05). CONCLUSION An intraoperative low-dose dexmedetomidine continuous infusion can reduce emergence agitation following general anaesthesia in elderly patients (> 64-years-old), remain stable in terms of haemodynamics, and not lead to delays in anaesthesia recovery time and extubation time.

Abstract
BACKGROUND Current evidence on the effect of dexmedetomidine in early postoperative recovery is limited. We conducted a systematic review to evaluate the effect of dexmedetomidine on the length of stay (LOS) and recovery profile in postanesthesia care unit (PACU) patients. METHODS The study protocol is registered on International Prospective Register of Systematic Reviews (PROSPERO; CRD42021240559). No specific funding or support was received. We conducted searches in MEDLINE, Embase, PubMed, and Cochrane Library to March 31, 2021 for peer-reviewed randomized controlled studies comparing adult patients who received intravenous dexmedetomidine and placebo undergoing noncardiac, nonneurosurgical procedures under general anesthesia. All studies reporting statistics relating to the duration of stay in the recovery ward or PACU, the primary outcome, were included. We performed individual random-effect meta-analysis on the primary and secondary outcomes (time to extubation, emergence agitation, cough, pain, postoperative nausea and vomiting, shivering, residual sedation, bradycardia, and hypotension) using Stata version 17.0. Evidence was synthesized as mean difference (MD) and risk ratio (RR) for continuous and dichotomous variables, respectively. The quality of evidence was assessed using the revised Cochrane risk-of-bias tool for randomized trials (RoB 2) tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS Thirty-three studies including 2676 patients were eligible for analysis. All studies had low risk or some concerns of overall bias and provided low-to-high certainty evidence for all studied outcomes. Dexmedetomidine was not associated with a significantly increased PACU LOS (MD, 0.69 minute; 95% confidence interval [CI], -1.42 to 2.81 minutes). It was associated with a statistically but not clinically significant prolonged time to extubation (MD, 1 minute; 95% CI, 0.32-1.68 minutes). Dexmedetomidine was associated with significantly reduced incidence of emergence agitation (RR, 0.38; 95% CI, 0.29-0.52), cough (RR, 0.69; 95% CI, 0.61-0.79), pain (RR, 0.50; 95% CI, 0.32-0.80), postoperative nausea and vomiting (RR, 0.54; 95% CI, 0.33-0.86), and shivering (RR, 0.24; 95% CI, 0.12-0.49) in PACU. There was an increased incidence of hypotension (RR, 5.39; 95% CI, 1.12-5.89) but not residual sedation (RR, 1.23; 95% CI, 0.20-7.56) or bradycardia (RR, 5.13; 95% CI, 0.96-27.47) in the dexmedetomidine group. CONCLUSIONS The use of dexmedetomidine did not increase the duration of PACU LOS but was associated with reduced emergence agitation, cough, pain, postoperative nausea and vomiting, and shivering in PACU. There was an increased incidence of hypotension but not residual sedation or bradycardia in PACU.

Role of Dexmedetomidine in Early POCD in Patients Undergoing Thoracic Surgery. BIOMED RESEARCH INTERNATIONAL 2021; 2021:8652028. [PMID: 34859103 PMCID: PMC8632391 DOI: 10.1155/2021/8652028] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 11/01/2021] [Indexed: 02/05/2023]
Abstract
Objective To evaluate whether a low-dose perioperative infusion of Dex reduces early POCD. Design This study was a double-blind, randomized, placebo-controlled trial that randomly assigned patients to Dex or saline placebo infused during surgery and patient-controlled intravenous analgesia (PCIA) infusion. Patients were assessed for postoperative cognitive decline. Interventions. Dex was infused at a loading dose of 0.5 μg/kg intravenously (15 min after entering the operation room) followed by a continuous infusion at a rate of 0.5 μg/kg/h until one-lung ventilation or artificial pneumothorax ended. Patients in the Dex group received regular PCIA pump with additional dose of Dex (200 μg). Results In total, 126 patients were randomized, and 102 patients were involved in the result analysis. The incidence of POCD was 36.54% (19/52) in the Dex group and 32.00% (16/50) in the normal saline (NS) group, with no statistic difference. No significant difference was observed between the two groups in terms of Telephone Interview for Cognitive Status-Modified (TICS-m) scores at different times. However, the TICS-m score at 7 days after surgery was significantly lower than that at 30 days in 102 patients (32.93 ± 0.42 vs. 33.92 ± 0.47, P = 0.03). The visual analogue scale scores in the Dex group were significantly lower than those in the NS group 1 day postoperation at rest and activity (2.00 [1.00-3.00] vs. 3.00 [2.00-4.00], P < 0.01; 4.00 [3.00-5.00] vs. 5.00 [4.00-6.00], P < 0.05, respectively). Patients receiving Dex or NS had no statistical difference in activities of daily living (ADLs) scores at 7 and 30 days after surgery, but the ADL score at 30 days after surgery showed a significant reduction compared with that at 7 days (P < 0.01). Patients in the Dex group had a shorter hospital length of stay (15.26 ± 3.77 vs. 17.69 ± 5.09, P = 0.02) and less expenses (52458.71 ± 10649.30 vs. 57269.03 ± 9269.98, P = 0.04) than those in the NS group. Conclusions Low-dose Dex in the perioperative period did not reduce the incidence of early POCD in thoracic surgery. However, it relieved postoperative pain, decreased the hospitalization expenses, and shortened the length of stay.

Abstract
BACKGROUND By inhibiting neuroinflammation dexmedetomidine may be neuroprotective in patients undergoing cranial surgery, but it reduces cardiac output and cerebral blood flow. OBJECTIVE To investigate whether intra-operative dexmedetomidine combined with goal-directed haemodynamic therapy (GDHT) has neuroprotective effects in cranial surgery. DESIGN A double-blind, single-institution, randomised controlled trial. SETTING A single university hospital, from April 2017 to April 2020. PATIENTS A total of 160 adults undergoing elective cranial surgery. INTERVENTION Infusion of dexmedetomidine (0.5 μg kg-1 h-1) or saline combined with GDHT to optimise stroke volume during surgery. MAIN OUTCOME MEASURES The proportion who developed postoperative neurological complications was compared. Postoperative disability was assessed using the Barthel Index at time points between admission and discharge, and also the 30-day modified Rankin Scale (mRS). Postoperative delirium was assessed. The concentration of a peri-operative serum neuroinflammatory mediator, high-mobility group box 1 protein (HMGB1), was compared. RESULTS Fewer patients in the dexmedetomidine group developed new postoperative neurological complications (26.3% vs. 43.8%; P = 0.031), but the number of patients developing severe neurological complications was comparable between the two groups (11.3% vs. 20.0%; P = 0.191). In the dexmedetomidine group the Barthel Index reduction [0 (-10 to 0)] was less than that in the control group [-5 (-15 to 0)]; P = 0.023, and there was a more favourable 30-day mRS (P = 0.013) with more patients without postoperative delirium (84.6% vs. 64.2%; P = 0.012). Furthermore, dexmedetomidine induced a significant reduction in peri-operative serum HMGB1 level from the baseline (222.5 ± 408.3 pg ml-1) to the first postoperative day (152.2 ± 280.0 pg ml-1) P = 0.0033. There was no significant change in the control group. The dexmedetomidine group had a lower cardiac index than did the control group (3.0 ± 0.8 vs. 3.4 ± 1.8 l min-1 m-2; P = 0.0482) without lactate accumulation. CONCLUSIONS Dexmedetomidine infusion combined with GDHT may mitigate neuroinflammation without undesirable haemodynamic effects during cranial surgery and therefore be neuroprotective.

Abstract
BACKGROUND Emergence agitation (EA) after general anesthesia is a common complication in the post-anesthesia care unit (PACU). Once EA occurs, there are still no guidelines established for the treatment in adults. Propofol is excessively used in managing agitated patients in the PACU, but it lacks analgesia and can result in apnea. Intraoperative infusion of dexmedetomidine has been proven to have a preventive effect on EA, but the treatment effect of dexmedetomidine on EA remains unknown. This study aims to compare the effects between dexmedetomidine and propofol on relieving EA in adult patients after general anesthesia in the PACU. METHODS In this randomized, superiority, controlled clinical study, a total of 120 adult patients aged 18-65 years of both genders, with American Society of Anesthesiologists (ASA) classification I or II developing EA in the PACU after general anesthesia, will be enrolled. Patients will be randomized at a 1:1 ratio into two groups, receiving either a single dose of dexmedetomidine (0.7μg/kg) or propofol (0.5 mg/kg). The primary outcome is the proportion of patients having a recurrent EA within 15 min after intervention in the PACU. DISCUSSION Previous studies have focused on premedication for preventing EA, while therapeutics for reliving EA have rarely been reported. To our knowledge, this study is the first randomized, superiority, controlled trial to compare a bolus of dexmedetomidine with the current routine care for this indication.

Abstract
Background: Emergence agitation (EA) in adult patients under general anesthesia leads to increased postoperative complications and heavy medical burden. Unfortunately, its pathogenesis has not been clarified until now. The purpose of the present study was to explore the relationship between preoperative serum metabolites and EA. Methods: We used an untargeted metabolic analysis method to investigate the different metabolomes in the serum of EA patients and non-EA patients undergoing elective surgical procedures after the induction of general anesthesia. A Richmond Agitation-Sedation Scale score ≥ +2 was diagnosed as EA during postoperative emergence. Non-EA patients were matched with EA patients according to general characteristics. Preoperative serum samples of the two groups were collected to investigate the association between serum metabolites and EA development. Results: The serum samples of 16 EA patients with 34 matched non-EA patients were obtained for metabolic analysis. After screening and alignment with databases, 31 altered metabolites were detected between the two groups. These metabolites were mainly involved in the metabolism of lipids, purines, and amino acids. Analyses of receiver-operating characteristic curves showed that the preoperative alterations of choline, cytidine, glycerophosphocholine, L-phenylalanine, oleamide, and inosine may be associated with adult EA. Conclusion: Multiple metabolic abnormalities (including those for lipids, purines, and amino acids) and other pathological processes (e.g., neurotransmitter imbalance and oxidative stress) may contribute to EA. Several altered metabolites in serum before surgery may have predictive value for EA diagnosis. This study might afford new metabolic clues for the understanding of EA pathogenesis.

Abstract
OBJECTIVE To describe pharmacological and non-pharmacological practices for delirium, carried out by psychiatry residents and psychiatrists in Colombia. METHODS An anonymous survey was conducted based on the consensus of experts of the Liaison Psychiatry Committee of the Asociación Colombiana de Psiquiatría [Colombian Psychiatric Association] and on the literature review. It was sent by email to the association members. RESULTS 101 clinicians participated. Non-pharmacological preventive measures such as psychoeducation, correction of sensory problems or sleep hygiene are performed by 70% or more. Only about 1 in 10 participants are part of an institutional multi-component prevention programme. The preventive prescription of drugs was less than 20%. Regarding non-pharmacological treatment, more than 75% recommend correction of sensory difficulties, control of stimuli and reorientation. None of the participants indicated that the care at their centres is organised to enhance non-pharmacological treatment. 17.8% do not use medication in the treatment of delirium. Those who use it prefer haloperidol or quetiapine, particularly in hyperactive or mixed motor subtypes. CONCLUSIONS The practices of the respondents coincide with those of other experts around the world. In general, non-pharmacological actions are individual initiatives, which demonstrates the need in Colombian health institutions to commit to addressing delirium, in particular when its prevalence and consequences are indicators of quality of care.

Abstract
One-lung ventilation (OLV), a common ventilation technique, is associated with perioperative lung injury, tightly connected with inflammatory responses. Dexmedetomidine has shown positive anti-inflammatory effects in lung tissues in pre-clinical models. This study investigated the efficacy of dexmedetomidine for suppressing inflammatory responses in patients requiring OLV. We searched PubMed, MEDLINE, Embase, Scopus, Ovid, and Cochrane Library for randomized controlled trials focusing on dexmedetomidine's anti-inflammatory effects on patients requiring OLV without any limitation on the year of publication or languages. 20 clinical trials were assessed with 870 patients in the dexmedetomidine group and 844 in the control group. Our meta-analysis investigated the anti-inflammatory property of dexmedetomidine perioperatively [T1 (30-min OLV), T2 (90-min OLV), T3 (end of surgery) and T4 (postoperative day 1)], demonstrating that dexmedetomidine's intraoperative administration resulted in a significant reduction in serum concentration of interleukin-6, tumor necrosis factor-α and other inflammatory cytokines perioperatively. By calculating specific I2 index, significant heterogeneity was observed on all occasions, with I2 index ranging from 95% to 99%. For IL-6 changes, sensitivity analysis showed that the exclusion of a single study led to a significant decrease of heterogeneity (96%-0%; p < 0.00001). Besides, pulmonary oxygenation was ameliorated in the dexmedetomidine group comparing with the control group. In conclusion, perioperative administration of dexmedetomidine can attenuate OLV induced inflammation, ameliorate pulmonary oxygenation, and may be conducive to a decreased occurrence of postoperative complications and better prognosis. However, the results should be prudently interpreted due to the evidence of heterogeneity and the limited number of studies.

Abstract
BACKGROUND Postoperative delirium (POD) not only increases the medical burden but also adversely affects patient prognosis. Although some cases of delirium can be avoided by early intervention, there is no clear evidence indicating whether any of these measures can effectively prevent POD in specific patient groups. OBJECTIVE The aim of this meta-analysis was to compare the efficacy and safety of the existing preventive measures for managing POD. METHODS The PubMed, OVID (Embase and MEDLINE), Web of Science, and the Cochrane Library databases were searched for articles published before January 2020. The relevant randomized controlled trials (RCTs) were selected based on the inclusion and exclusion criteria. Data extraction and methodological quality assessment were performed according to a predesigned data extraction form and scoring system, respectively. The interventions were compared on the basis of the primary outcome like incidence of POD, and secondary outcomes like duration of delirium and the length of intensive care unit and hospital stay. RESULTS Sixty-three RCTs were included in the study, covering interventions like surgery, anesthesia, analgesics, intraoperative blood glucose control, cholinesterase inhibitors, anticonvulsant drugs, antipsychotic drugs, sleep rhythmic regulation, and multi-modal nursing. The occurrence of POD was low in 4 trials that monitored the depth of anesthesia with bispectral index during the operation (P < .0001). Two studies showed that supplementary analgesia was useful for delirium prevention (P = .002). Seventeen studies showed that perioperative sedation with α2-adrenergic receptor agonists prevented POD (P = .0006). Six studies showed that both typical and atypical antipsychotic drugs can reduce the incidence of POD (P = .002). Multimodal nursing during the perioperative period effectively reduced POD in 6 studies (P < .00001). Furthermore, these preventive measures can reduce the duration of delirium, as well as the total and postoperative length of hospitalized stay for non-cardiac surgery patients. For patients undergoing cardiac surgery, effective prevention can only reduce the length of intensive care unit stay. CONCLUSION Measures including intraoperative monitoring of bispectral index, supplemental analgesia, α2-adrenergic receptor agonists, antipsychotic drugs, and multimodal care are helpful to prevent POD effectively. However, larger, high-quality RCTs are needed to verify these findings and develop more interventions and drugs for preventing postoperative delirium.

Abstract
Many pharmacologic agents were investigated for the effect to prevent delirium. We aimed to comprehensively compare the effect of the pharmacological interventions to prevent postoperative delirium. A Bayesian network meta-analysis of randomized trials was performed using random effects model. PubMed, the Cochrane Central Register of Controlled Trials, and Embase were searched on 20 January 2021. Randomized trials comparing the effect of a drug to prevent postoperative delirium with another drug or placebo in adult patients undergoing any kind of surgery were included. Primary outcome was the postoperative incidence of delirium. Eighty-six trials with 26,992 participants were included. Dexmedetomidine, haloperidol, and atypical antipsychotics significantly decreased the incidence of delirium than placebo [dexmedetomidine: odds ratio 0.51, 95% credible interval (CrI) 0.40-0.66, moderate quality of evidence (QOE); haloperidol: odds ratio 0.59, 95% CrI 0.37-0.95, moderate QOE; atypical antipsychotics: odds ratio 0.27, 95% CrI 0.14-0.51, moderate QOE]. Dexmedetomidine and atypical antipsychotics had the highest-ranking probabilities to be the best. However, significant heterogeneity regarding diagnostic time window as well as small study effects precludes firm conclusion.

Abstract
Delirium occurs commonly following major non-cardiac and cardiac surgery and is associated with: postoperative mortality; postoperative neurocognitive dysfunction; increased length of hospital stay; and major postoperative complications and morbidity. The aim of this study was to investigate the effect of peri-operative administration of dexmedetomidine on the incidence of postoperative delirium in non-cardiac and cardiac surgical patients. In this randomised, double-blind placebo-controlled trial we included 63 patients aged ≥ 60 years undergoing major open abdominal surgery or coronary artery bypass graft surgery with cardiopulmonary bypass. The primary outcome was the incidence of postoperative delirium, as screened for with the Confusion Assessment Method. Delirium assessment was performed twice daily until postoperative day 5, at the time of discharge from hospital or until postoperative day 14. We found that dexmedetomidine was associated with a reduced incidence of postoperative delirium within the first 5 postoperative days, 43.8% vs. 17.9%, p = 0.038. Severity of delirium, screened with the Intensive Care Delirium Screening Checklist, was comparable in both groups, with a mean maximum score of 1.54 vs. 1.68, p = 0.767. No patients in the dexmedetomidine group died while five (15.6%) patients in the placebo group died, p = 0.029. For patients aged ≥ 60 years undergoing major cardiac or non-cardiac surgery, we conclude that the peri-operative administration of dexmedetomidine is associated with a lower incidence of postoperative delirium.

J Clin Anesth 2021; 73:110308. [PMID: 33930679 DOI: 10.1016/j.jclinane.2021.110308] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 04/06/2021] [Accepted: 04/07/2021] [Indexed: 12/22/2022]
Abstract
STUDY OBJECTIVE To evaluate the efficacy of perioperative dexmedetomidine (DEX) administration for preventing delirium in adults after non-cardiac surgery. DESIGN Systematic review and meta-analysis of randomized controlled trials (RCTs). INTERVENTIONS Perioperative administration of DEX to prevent delirium in adults following non-cardiac surgery. MEASUREMENTS The incidence of postoperative delirium (POD). METHODS The databases of PubMed, Embase and Cochrane Central Register were searched from inception to Mar 4, 2021 for all available RCTs that assessed DEX for POD in adults after non-cardiac surgery. Risk ratio (RR) with a 95% confidence interval (CI) was calculated for dichotomous data. Standardized mean difference (SMD) was calculated for continuous data. Risk of bias was assessed using the second version of the Cochrane risk-of-bias tool for RCTs (RoB 2.0), and the level of certainty for main outcomes were assessed by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. MAIN RESULTS Thirteen studies, including the meta-analysis with a total of 4015 patients (DEX group: 2050 patients; placebo group: 1965 patients), showed that DEX significantly reduced the incidence of POD in adults after non-cardiac surgery compared with control group (RR: 0.60; 95%CI: 0.46 to 0.77, P = 0.0001, I2 = 55%, GRADE = moderate). Meanwhile, there was a statistical difference by the subgroup analysis between the mean age ≥ 65 years group and the mean age<65 years group. There were no statistical differences in length of hospital stay following surgery (SMD: -0.36; 95%CI: -0.80 to 0.07, P = 0.1, I2 = 97%, GRADE = low) and all-cause mortality rate (RR:0.57; 95%CI: 0.25 to 1.28, P < 0.17, I2 = 0%, GRADE = moderate) compared with placebo group. However, Meta-analysis showed that DEX administration significantly resulted in intraoperative bradycardia when compared with placebo group (RR: 1.39; 95%CI: 1.14 to 1.69, P = 0.0009, I2 = 0%, GRADE = high), and as well as intraoperative hypotension (RR: 1.25; 95%CI: 1.11 to 1.42, P = 0.0004, I2 = 0%, GRADE = high). CONCLUSION This systematic review and meta-analysis suggests that perioperative administration of DEX could significantly reduce the incidence of POD in patients elder than 65 years following non-cardiac surgery. However, there was no definite evidence that perioperative DEX could reduce the incidence of POD in patients younger than 65 years of age after non-cardiac surgery. In addition, perioperative DEX administration was associated with an elevated risk of bradycardia and hypotension.

Dexmedetomidine for prevention of postoperative delirium in older adults undergoing oesophagectomy with total intravenous anaesthesia: A double-blind, randomised clinical trial. Eur J Anaesthesiol 2021; 38:S9-S17.

Abstract
BACKGROUND Dexmedetomidine is known to be a sedative. Recent studies suggest that administration of dexmedetomidine can prevent postoperative delirium (POD) which has been confirmed as a common complication after major surgery. However, its effects in patients undergoing oesophagectomy are scarce. OBJECTIVE To investigate the efficacy and safety of dexmedetomidine in reducing POD in elderly patients after transthoracic oesophagectomy with total intravenous anaesthesia (TIVA). DESIGN A randomised, double-blind, placebo-controlled trial. SETTING Single-centre, tertiary care hospital, November 2016 to September 2018. PATIENTS Eligible patients (n = 177) undergoing transthoracic oesophagectomy were randomly assigned to receive total intravenous anaesthesia (TIVA, n = 87) or dexmedetomidine with TIVA (DEX-TIVA, n = 90). INTERVENTIONS Patients receiving DEX-TIVA received a loading dose of dexmedetomidine (0.4 μg kg-1), over 15 min, followed by a continuous infusion at a rate of 0.1 μg kg-1 h-1 until 1 h before the end of surgery. Patients receiving TIVA received physiological saline with a similar infusion rate protocol. OUTCOME MEASURES The primary outcome was the incidence of POD. The secondary endpoints were the incidence of emergence agitation, serum interleukin-6 (IL-6) levels and haemodynamic profile. RESULTS All randomised patients were included with planned intention-to-treat analyses for POD. Delirium occurred in 15 (16.7%) of 90 cases given dexmedetomidine, and in 32 (36.8%) of 87 cases given saline (P = 0.0036). The DEX-TIVA group showed less frequent emergence agitation than the TIVA group (22.1 vs. 48.0%, P = 0.0058). The incremental change in surgery-induced IL-6 levels was greater in the TIVA group than DEX-TIVA group (P < 0.0001). CONCLUSION Adding peri-operative dexmedetomidine to a total intravenous anaesthetic safely reduces POD and emergence agitation in elderly patients undergoing open transthoracic oesophagectomy. These benefits were associated with a postoperative reduction in circulating levels of the pro-inflammatory cytokine IL-6 and stabilisation of the haemodynamic profile.

Abstract
OBJECTIVE To explore the immunomodulatory mechanism and optimal dose of dexmedetomidine (DEX) for preventing postoperative cognitive dysfunction (POCD) in elderly patients undergoing spinal surgery. OBJECTIVE A total of 120 elderly patients undergoing elective spinal surgery with general anesthesia were randomized into 4 groups to receive a loading dose of 0.3 μg/kg DEX for 10 min before anesthesia induction followed by maintenance doses of 0.2, 0.5, and 0.8 μg · kg-1·h-1 (low-, medium-, and high-dose DEX groups, respectively) or an equal volume of normal saline (control group). DEX and saline was discontinued 40 min before the end of the surgery. Before induction (D0) and on day 1 (D1), day 3 (D2) and day 7 (D3) after the operation, the cognitive function of the patients was assessed using the MMSE scale and their serum levels of β-amyloid (Aβ), TNF-α, IL-1β and IL-6 were measured. The occurrence of adverse effects including bradycardia and hypotension and the recovery time of the patients were recorded. OBJECTIVE Compared with those on D0, serum levels of Aβ, IL-1β, IL-6, and TNF-α on D1 were markedly increased in all the groups (P < 0.05); the levels of Aβ decreased to the baseline level on D3 in medium- and high-dose DEX groups (P > 0.05) but remained high in the other two groups. On D2, TNF-α, L-1β and IL-6 recovered their baseline levels in medium- and high-dose DEX groups (P > 0.05) but remained elevated in the other two groups. The incidences of POCD in medium- and high-dose DEX groups were comparable but significantly lower than that in the control group (P < 0.05). The incidences of hypotension and bradycardia were the highest in high-dose DEX group (P < 0.01), which also had longer recovery time than the other 3 groups (P < 0.05). OBJECTIVE With a loading dose of 0.3 μg/kg followed by a maintenance doses of 0.5 μg · kg-1·h-1, DEX can effectively reduce the incidence of POCD in elderly patients undergoing spinal surgery by inhibiting the production of Aβ and pro-inflammatory cytokines.

Abstract
Emergence agitation (EA) is a self-limited state of psychomotor excitement during awakening from general anesthesia. EA is confined to the emergence period as consciousness is restored, which sharply distinguishes it from other postoperative delirium states. Sporadic episodes of EA may become violent with the potential for harm to both patients and caregivers, but the long-term consequences of such events are not fully understood. Current literature on EA in adults is limited to small-scale studies with inconsistent nomenclature, variable time periods that define emergence, a host of different surgical populations, and conflicting diagnostic criteria. Therefore, true incidence rates and risk factors are unknown. In adult noncardiac surgery, the incidence of EA is approximately 19%. Limited data suggest that young adults undergoing otolaryngology operations with volatile anesthetic maintenance may be at the highest risk for EA. Currently suggested EA mechanisms are theoretical but might reflect underblunted sympathetic activation in response to various internal (eg, flashbacks or anxiety) or external (eg, surgical pain) stimuli as consciousness returns. Supplemental dexmedetomidine and ketamine may be utilized for EA prevention. Compared to the civilian population, military veterans may be more vulnerable to EA due to high rates of posttraumatic stress disorder (PTSD) manifesting as violent flashbacks; however, confirmatory data are limited. Nonetheless, expert military medical providers suggest that use of patient-centered rapport tactics, PTSD trigger identification and avoidance, and grounding measures may alleviate hyperactive emergence phenomena. Future research is needed to better characterize EA in veterans and validate prophylactic measures to optimize care for these patients. This narrative review provides readers with an important framework to distinguish EA from delirium. Furthermore, we summarize current knowledge of EA risk factors, mechanisms, and adult management strategies and specifically revisit them in the context of veteran perioperative health. The anesthesiology care team is ideally positioned to further explore EA and develop effective prevention and treatment protocols.

Abstract
Background The catheter-related bladder discomfort (CRBD) of male patients is a common clinical problem, albeit lacking effective solutions. The present study aimed to investigate whether intravesical dexmedetomidine instillation alleviates the postoperative urinary discomfort in male patients with catheter under general anesthesia. Methods This single-blinded, prospective, randomized study included a total of 167 male patients American Society of Anesthesiologists (ASA) physical status I-II scheduled for surgery under general anesthesia were allocated to two groups: 84 in the dexmedetomidine group and 83 in the control group. Dexmedetomidine group patients received intravesical instillation of the drug 0.5 μg/kg and normal saline 20 mL, while the control group received intravesical instillation of 20 mL normal saline. The catheter was clamped for 30 min after intravesical instillation for all patients. CRBD scores and urethra pain numerical rating scale (NRS) scores were measured at admittance to post-anesthesia care unit (PACU) (T0), intravesical instillation (T1), 30 min (T2), 60 min (T3), 2 h (T4) after intravesical instillation, discharged from PACU (T5), and 6 h (T6) and 24 h (T7) after the operation. Patient satisfaction at discharge from PACU and 24 h post-operation were compared between the two groups. Results CRBD scores and urethra pain NRS scores after 30 min of intravesical dexmedetomidine instillation to 24 h post-operation were significantly lower than the control group (p < 0.001), and patient satisfaction was higher at discharge from PACU and 24 h post-operation (p < 0.001). No differences were detected in Steward score out of PACU (p = 0.213) and from the time of the end of operation to fully awake (p = 0.417). Conclusion Intravesical dexmedetomidine instillation reduces postoperative urinary discomfort and urethra pain and improves satisfaction in male patients under general anesthesia.

Effect of Intraoperative Dexmedetomidine Dose on Postoperative First Night Sleep Quality in Elderly Surgery Patients: A Retrospective Study With Propensity Score-Matched Analysis. Front Med (Lausanne) 2020; 7:528. [PMID: 33117823 PMCID: PMC7574233 DOI: 10.3389/fmed.2020.00528] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Accepted: 07/27/2020] [Indexed: 02/05/2023] Open
Abstract
Background: Postoperative sleep disorder is common in elderly surgery patients, and it often worsens their recovery after surgery. This study aimed to explore the effect of intraoperative dexmedetomidine dose on postoperative sleep quality. Methods: Based on information regarding dexmedetomidine use during surgery from an electronic medical record system, 4,349 elderly surgery patients were divided into three groups: 1,374 without intraoperative use of dexmedetomidine (Non-DEX), 917 with dexmedetomidine 0.1–0.2 μg/kg/h (Low-DEX), and 2,058 with dexmedetomidine >0.2 μg/kg/h (High-DEX). The numerical rating scale (NRS) for sleep disturbance during the first night after surgery was recorded, and the incidence of NRS ≥ 6 was considered the primary outcome. Results: NRS (P < 0.001) and incidence of severe sleep disturbance (P < 0.001) were lower in patients receiving intraoperative dexmedetomidine than in those without the intraoperative use of dexmedetomidine. Patients in the Low-DEX group had the lowest incidence, followed by those in the High-DEX and Non-DEX groups (6.7% vs. 13.7% vs. 19.5%). After propensity score matching, 906 pairs of elderly surgery patients were included in the Low-DEX and High-DEX groups, and the Low-DEX group had lower NRS (2.7 ± 2.1 vs. 3.1 ± 2.4, P < 0.001) than the High-DEX group. The incidence of severe sleep disturbance was lower in the Low-DEX group than in the High-DEX group (6.6% vs. 12.8%) with an odds rate of 0.48 (95% confidence interval, 0.35 to 0.67). Conclusions: For elderly patients, intraoperative dexmedetomidine use can significantly improve the quality of the first night sleep after surgery. Low-dose (0.1–0.2 μg/kg/h) dexmedetomidine can have an improvement effect on sleep quality, and it is recommended to improve the quality of postoperative sleep.

Abstract
Background Delirium is an acute status of brain dysfunction that commonly occurs in patients who have undergone cardiac surgery, and increases morbidity and mortality. It is associated with risk factors, such as older age, use of narcotics, cardiopulmonary bypass, and hypothermia. Dexmedetomidine infusion might exert a neuroprotective effect. However, the effect of perioperative administration of dexmedetomidine on the incidence of postoperative delirium (POD) in patients undergoing cardiac or non-cardiac surgery is yet controversial. The present study aimed to reveal the effect of intraoperative dexmedetomidine administration on the incidence of delirium in adult patients following cardiac surgery. Methods This single-center, randomized, double-blinded, and placebo-controlled trial consisted of 652 patients randomly divided into two groups: dexmedetomidine and placebo. 0.6 μg/kg dexmedetomidine will be infused 10 min after central vein catheterization, followed by a continuous infusion at a speed of 0.4 μg/kg/h until the end of surgery in the dexmedetomidine group, while normal saline will be administered at the same rate in the placebo group. The primary outcome is the incidence of POD during the first 7 days post-surgery. The secondary outcomes include duration of mechanical ventilation after surgery, duration of stay in the intensive care unit and the hospital after surgery, incidence of hypotension during or after dexmedetomidine infusion, acute kidney injury and sudden arrhythmia during the hospital stay postoperatively, and all-cause mortality in 30 and 90 days after surgery, respectively. Discussion This study was approved by the Ethics Committee of the Chinese Academy of Medical Sciences Fuwai Hospital on 6 March 2019 (2019-1180). The results will be disseminated at academic conferences and submitted to peer-reviewed publications. Either positive or negative results will provide guidance for clinical practice. Trial registration The Chinese Clinical Trial Registry (http://www.chictr.org.cn) ChiCTR1900022583. Registered on 17 April 2019.

Survey of psychiatrists and psychiatry residents in Colombia about their preventive and therapeutic practices in delirium. REVISTA COLOMBIANA DE PSIQUIATRIA (ENGLISH ED.) 2020; 50:S0034-7450(20)30031-7. [PMID: 33735057 DOI: 10.1016/j.rcp.2020.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 01/02/2020] [Accepted: 02/20/2020] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To describe pharmacological and non-pharmacological practices for delirium, carried out by psychiatry residents and psychiatrists in Colombia. METHODS An anonymous survey was conducted based on the consensus of experts of the Liaison Psychiatry Committee of the Asociación Colombiana de Psiquiatría [Colombian Psychiatric Association] and on the literature review. It was sent by email to the association members. RESULTS 101 clinicians participated. Non-pharmacological preventive measures such as psychoeducation, correction of sensory problems or sleep hygiene are performed by 70% or more. Only about 1 in 10 participants are part of an institutional multi-component prevention programme. The preventive prescription of drugs was less than 20%. Regarding non-pharmacological treatment, more than 75% recommend correction of sensory difficulties, control of stimuli and reorientation. None of the participants indicated that the care at their centres is organised to enhance non-pharmacological treatment. 17.8% do not use medication in the treatment of delirium. Those who use it prefer haloperidol or quetiapine, particularly in hyperactive or mixed motor subtypes. CONCLUSIONS The practices of the respondents coincide with those of other experts around the world. In general, non-pharmacological actions are individual initiatives, which demonstrates the need in Colombian health institutions to commit to addressing delirium, in particular when its prevalence and consequences are indicators of quality of care.

Abstract
PURPOSE OF REVIEW Effective acute pain management has evolved considerably in recent years and is a primary area of focus in attempts to defend against the opioid epidemic. Persistent postsurgical pain (PPP) has an incidence of up to 30-50% and has negative outcome of quality of life and negative burden on individuals, family, and society. The 2016 American Society of Anesthesiologists (ASA) guidelines states that enhanced recovery after surgery (ERAS) forms an integral part of Perioperative Surgical Home (PSH) and is now recommended to use a multimodal opioid-sparing approach for management of postoperative pain. As such, dexmedetomidine is now being used as part of ERAS protocols along with regional nerve blocks and other medications, to create a satisfactory postoperative outcome with reduced opioid consumption in the Post anesthesia care unit (PACU). RECENT FINDINGS Dexmedetomidine, a selective alpha2 agonist, possesses analgesic effects and has a different mechanism of action when compared with opioids. When dexmedetomidine is initiated at the end of a procedure, it has a better hemodynamic stability and pain response than ropivacaine. Dexmedetomidine can be used as an adjuvant in epidurals with local anesthetic sparing effects. Its use during nerve blocks results in reduced postoperative pain. Also, local infiltration of IV dexmedetomidine is associated with earlier discharge from PACU. Perioperative use of dexmedetomidine has significantly improved postoperative outcomes when used as part of ERAS protocols. An in-depth review of the use of dexmedetomidine in ERAS protocols is presented for clinical anesthesiologists.

Abstract
INTRODUCTION Postoperative delirium is a common complication after major surgical procedures and affects outcomes and long-term survival. We identified factors associated with postoperative delirium in patients undergoing esophagectomy. METHODS Retrospective cohort analysis of 378 patients undergoing esophagectomy. We examined the association between postoperative delirium (DSM-V) criteria with respect to baseline variables and postoperative complications. RESULTS Postoperative delirium was diagnosed in 64 (16.93%) patients and associated with increasing age (P < .05), chronic obstructive pulmonary disease (P = .07), pneumonia (P = .01), transfusion intraoperatively or within 72 hours of surgery (P < .001), and sepsis (P = .001). Unplanned intubation and increased length of stay (median, 14 days) were significant in patients with delirium (P = .001 and P < .001, respectively). In a secondary analysis, surgical technique and operative approach were associated with delirium. Modified McKeown (three-hole) esophagectomy was twice more likely to develop delirium compared with Ivor Lewis (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.03-4.23). The strongest association was found between delirium and open techniques (thoracotomy and laparotomy) as compared with minimally invasive techniques (thoracoscopy and laparoscopy) (OR, 2.66; 95% CI, 1.22-5.76). Survival was similar between both groups. CONCLUSIONS Postoperative delirium is common and associated with complications following esophagectomy. Identification of predisposing factors such as age and pre-existing pulmonary diseases and proper selection of surgical treatment may reduce delirium and improve surgical outcomes.

Abstract
OBJECTIVES Emergence agitation is a negative behavior commonly recorded after pediatric tonsillectomy. We investigated the efficacy of preoperative premedication with oral transmucosal buccal dexmedetomidine on the incidence and severity of emergence agitation in preschool children undergoing tonsillectomy under sevoflurane anesthesia. METHODS Ninety patients aged (3-6 years), ASA I-II were enrolled into three groups (n = 30) to receive oral transmucosal dexmedetomidine 0.5 μg.kg-1 (Group DEX I), 1 μg.kg-1 (Group DEX II) or saline placebo (Group C). Our primary endpoint was the Watcha agitation score at emergence in PACU. Secondary outcomes were preoperative sedation score, intraoperative hemodynamics, postoperative Objective Pain Scale (OPS) and adverse effects. RESULTS The patients' demographics, preoperative sedation scores and extubation time showed no difference between groups. Significant differences between groups in incidence and frequency distribution of each grade of Watcha score were evident at 5 minutes (p = 0.007), 10 minutes (p = 0.034), 30 minutes (p = 0.022), 45 minutes (p = 0.034) and 60 minutes (p = 0.026), postoperatively with significant differences between DEX I and II groups. DEX groups showed lower OPS scores at 5 minutes (p = 0.011), 10 minutes (p = 0.037) and 30 minutes (p = 0.044) after arrival at PACU, with no difference between DEX I and II groups. Patients in DEX II group exhibited lower intraoperative mean heart rate at 15 minutes (p = 0.020), and lower mean arterial pressure at 30 minutes, (p = 0.040), 45 minutes (p = 0.002) and 60 minutes (p = 0.006) with no significant differences between groups in other time points. CONCLUSION This study demonstrates the clinical advantage and the simple technique of oral transmucosal DEX premedication for emergence agitation in preschool children undergoing tonsillectomy under sevoflurane anesthesia compared with saline placebo.
