Effect of the alveolar recruitment maneuver during laparoscopic colorectal surgery on postoperative pulmonary complications: A randomized controlled trial.

Intraoperative lung-protective ventilation, including low tidal volume and positive end-expiratory pressure, reduces postoperative pulmonary complications. However, the effect and specific alveolar recruitment maneuver method are controversial. We investigated whether the intraoperative intermittent recruitment maneuver further reduced postoperative pulmonary complications while using a lung-protective ventilation strategy.

Relationship between muscle mass ratio and rocuronium dose required for maintaining deep neuromuscular blockade: A prospective observational study.

Background: Deep neuromuscular blockade (NMB) has benefits in various surgical procedures, however, precise quantitative neuromuscular monitoring is crucial for its proper maintenance and recovery. Neuromuscular blocking agent dosage relies on actual body weight (ABW), but this varies among individuals. Therefore, this study hypothesizes that there is a correlation between the rocuronium requirement for deep NMB and muscle mass ratio measured by bioelectric impedance analysis.

Methods: This prospective observational study included 38 patients undergoing hysteroscopic surgery.

Immediate retrograde amnesia induced by midazolam: a prospective, nonrandomized cohort study.

Background: Midazolam, a short-acting benzodiazepine, has sedative, anxiolytic, amnestic, and anticonvulsant effect. Given its advantages of rapid onset, short duration, and low toxicity, midazolam is optimal for any procedural sedation. Midazolam is known to cause anterograde amnesia; however, the possibility of retrograde amnesia has also been raised.

Effects of depth of neuromuscular blockade on the BIS-guided propofol requirement: A randomized controlled trial.

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.

Immediate retrograde amnesia induced by midazolam: A prospective, non-randomised cohort study.

Background: Midazolam, a short-acting benzodiazepine, has sedative, anxiolytic, amnestic and anticonvulsant effects. Given its advantages of rapid onset, short duration and low toxicity, midazolam is optimal for any procedural sedation. Midazolam is known to cause anterograde amnesia; however, the possibility of retrograde amnesia has also been raised.

Effects of magnesium on the dose of rocuronium for deep neuromuscular blockade: A randomised controlled trial.

Background: Magnesium is known to enhance the effect of rocuronium, but the extent is not quantified.

Design: A randomised controlled study.

Effects of Sugammadex on Post-Operative Pulmonary Complications in Laparoscopic Gastrectomy: A Retrospective Cohort Study.

The use of sugammadex can reduce post-operative residual neuromuscular blockade, which is known to increase the risk of post-operative respiratory events. However, its effect on post-operative pulmonary complications is not obvious. This study was performed to evaluate the effects of sugammadex on post-operative pulmonary complications in patients undergoing laparoscopic gastrectomy between 2013 and 2017.

Effects of deep neuromuscular blockade on the stress response during laparoscopic gastrectomy Randomized controlled trials.

Maintaining deep neuromuscular block during surgery improves surgical space conditions. However, its effects on patient outcomes have not been well documented. We examined whether maintaining deep neuromuscular blockade during surgery could decrease the stress response compared to moderate neuromuscular blockade.

Retrospective analysis of 30-day unplanned readmission after major abdominal surgery with reversal by sugammadex or neostigmine.

Background: Sugammadex is associated with fewer postoperative complications, but its impact on 30-day unplanned readmission is unclear.

Methods: This was a single-centre retrospective observational study of patients after major abdominal surgery between 2010 and 2017, where rocuronium was the only neuromuscular blocker used. The primary endpoint was the difference in incidence of 30-day unplanned readmission between reversal with sugammadex or neostigmine.
