Review Meta Analysis Comparative Study
Postoperative delirium under general anaesthesia by remimazolam versus propofol: A systematic review and meta-analysis of randomised controlled trials.
Remimazolam, an ultra-short-acting benzodiazepine, has similar clinical effects to propofol for sedation in general anaesthesia. However, it remains uncertain whether remimazolam could increase postoperative delirium (POD) compared with propofol. ⋯ Perioperative remimazolam administration did not increase POD and reduced the risk of intraoperative hypotension compared to propofol. Further large-scale RCTs are warranted to explore the association of remimazolam and POD. Systematic review protocol: PROSPERO CRD42024544122.

There have been important updates in the guidelines for the management of agitation in emergency room settings, including psychiatric emergency services. This manuscript provides a synthesis of current recommendations, combined with a detailed breakdown of the neurobiology of agitation, linking these neuroscientific dimensions with the pharmacological profiles of the drugs recommended by practice guidelines (as well as the profiles of other important agents). Since Project BETA (Best Practices in Evaluation and Treatment of Agitation) guidelines were published in 2012 (by the American Association for Emergency Psychiatry), there have been several developments in the standard of care, including an increase in use of ketamine and droperidol. Recommended treatment strategies for clinicians will be presented, including consideration of how to address specific causes of agitation.

ReviewRemimazolam in Cardiac Anesthesia: Analysis of Recent Data.
Interest in remimazolam has surged in recent years, thanks to its advantageous pharmacologic profile. This ultra-short-acting benzodiazepine is noted for its rapid onset and termination of action, organ-independent elimination, availability of a reversal agent, and excellent hemodynamic stability. Although the use of remimazolam has been explored in various anesthesia settings and procedures, data on its application in cardiovascular anesthesia and catheterization laboratory procedures remain limited. ⋯ The analysis shows that remimazolam offers anesthesia without significant hemodynamic instability and a reduced need for vasopressors, with an incidence of perioperative adverse events comparable to that of other agents. These findings are relevant for both the induction and maintenance of general anesthesia in catheterization laboratory procedures and general anesthesia in elective cardiac surgery. Although further research is needed to fully understand remimazolam's role in cardiovascular anesthesia, its favorable hemodynamic and safety profile suggests that it is a promising option for cardiac anesthesiologists in both the catheterization laboratory and the operating room.

Meta AnalysisHypnotics on Obstructive Sleep Apnea Severity and Endotypes: A Systematic Review and Meta-Analysis.
Rationale: Low arousal threshold and poor muscle responsiveness are common determinants of obstructive sleep apnea (OSA). Hypnotics were hypothesized as an alternative OSA treatment via raising the arousal threshold and possibly genioglossus responsiveness. Objectives: To examine the effect of common hypnotics on arousal threshold, OSA severity, and genioglossus responsiveness. ⋯ However, people with very low arousal threshold or those who exhibited a 0-25% arousal threshold increase from placebo experienced the greatest, yet still modest, post-treatment AHI reductions (∼10%). Hypnotics did not affect genioglossus responsiveness (high QoE). Conclusions: Further research testing or clinical use of hypnotics as OSA alternative treatments should be discouraged, unless in the presence of comorbid insomnia or as part of combination therapy in individuals with very low arousal threshold.

Meta Analysis
Effect of remimazolam on intra-operative hypotension: Systematic review and meta-analysis of randomised controlled trials.
Hypotension is common during anaesthesia. Increasing number of studies have reported that remimazolam may be associated with lower incidence of intra-operative hypotension compared with other anaesthetics. However, the results remain controversial. ⋯ Moderate-quality evidence shows that remimazolam administration to patients undergoing general anaesthesia or procedural sedation decreases the incidence of intra-operative hypotension and bradycardia.
