Case Reports
Complete separation of the tube from the mask during removal of a disposable laryngeal mask airway.
To describe a complication of the disposable laryngeal mask airway (LMA). ⋯ Although the use of the LMA is associated with rare and minimal complications, each airway should be carefully inspected before its use for loss of integrity resulting from sterilization or for defects in manufacturing.

Randomized Controlled Trial Clinical Trial
Dexamethasone 8 mg in combination with ondansetron 4 mg appears to be the optimal dose for the prevention of nausea and vomiting after laparoscopic cholecystectomy.
The combination of antiemetic drugs could be a solution to prevent severe postoperative nausea and vomiting (PONV). The aim of this randomized double blind, dose-ranging study was to determine the minimum single effective dose of dexamethasone combined with ondansetron for the prevention of PONV in patients undergoing laparoscopic cholecystectomy. ⋯ Our results suggest that 8 mg is the minimum dose of dexamethasone that, combined with ondansetron 4 mg will effectively prevent PONV in patients undergoing laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study Clinical Trial
Sevoflurane and isoflurane, but not propofol, decrease mivacurium requirements over time.
Volatile anesthetic agents potentiate neuromuscular blockade, but the magnitude of potentiation appears to be time dependent. The time course of this interaction was studied by measuring mivacurium infusion rates during sevoflurane, isoflurane and propofol anesthesia. ⋯ Sevoflurane and isoflurane do not prolong the effect of a bolus dose of mivacurium, but potentiation increases with time from 30-105 min of exposure. This interaction is greater with sevoflurane than isoflurane.
