Randomized Controlled Trial Comparative Study Clinical TrialComparison of sevoflurane-nitrous oxide and target-controlled propofol with fentanyl anesthesia for hysteroscopy.
A randomized prospective study was performed on the anesthetic induction, maintenance, and recovery characteristics of sevoflurane-nitrous oxide, compared to that of target- controlled propofol and fentanyl anesthesia, for forty day-case hysteroscopic surgery. The patients in the sevoflurane group (n = 20) received sevoflurane-nitrous oxide for both induction (8%) and maintenance (1 - 2%) of anesthesia, while the patients in the propofol group (n = 20) received target-controlled propofol (4 micro g/ml, 3-6 micro g/ml as occasion demanded) with fentanyl (1 micro g/kg). In both groups, the airway was maintained by a facemask with the patient breathing spontaneously during the surgery. ⋯ The postanesthetic Aldrete's recovery scores of the patients immediately after surgery were higher in the sevoflurane group. Propofol was associated with more drowsiness, with sevoflurane being associated with more nausea, in the recovery period; however, neither delayed the time to discharge (103.7 +/- 28.1 vs. 99.0 +/- 36.2 min). In conclusion, sevoflurane-nitrous oxide appears to be superior for day-case hysteroscopic surgery, than target-controlled propofol with fentanyl, with regards to the speed of recovery from anesthesia and the return to hemodynamic stability.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of priming with pancuronium or rocuronium on intubation with rocuronium in children.
Rocuronium is a non-depolarizing neuromuscular blocking agent which has a rapid onset and intermediate duration of action. The goal of this study was to compare the neuromuscular blocking actions of rocuronium with and without a priming dose of pancuronium or rocuronium in children. Thirty patients were randomly allocated into 3 groups. ⋯ The onset time and duration of block did not differ significantly between groups. However, the time to recovery in group II (24.5 +/- 9.9 min) was significantly prolonged compared to that in group I (12.7 +/- 3.1 min) or group III (12.7 +/- 3.9 min). We concluded that the use of rocuronium with a preceding dose of either pancuronium or rocuronium provided no advantage for intubation in children.
