In group R, all patients received flumazenil postoperatively...

BACKGROUND: Remimazolam is a novel benzodiazepine with fast onset and short half-life. We compared the effects of remimazolam and propofol on recovery profiles for general anesthesia in patients undergoing laparoscopic cholecystectomy. METHODS: We randomly assigned 108 patients to either a remimazolam (n=54) or propofol (n=54) group. Remimazolam and propofol were used for induction and maintanance of anesthesia. Following anesthesia, we recorded the time until an Aldrete score of 9 was achieved...

PURPOSE: Fentanyl is approved for use in many countries as an analgesic for patients requiring mechanical ventilation. However, it redistributes and accumulates easily in the plasma because of its long half-life. Remifentanil is a short context-sensitive half-life analgesic with a lower risk of redistribution and accumulation. MATERIALS AND METHODS: We conducted a multicenter, randomized, double-blind, non-inferiority trial. Critically ill patients requiring mechanical ventilation were randomly allocated to receive an infusion of either remifentanil or fentanyl for up to 72 h...
