Randomized Controlled Trial Comparative Study Clinical Trial
Delayed postoperative gastric emptying following intrathecal morphine and intrathecal bupivacaine.
A decrease in the rate of gastric emptying can delay resumption of enteral feeding, alter bioavailability of orally administered drugs, and result in larger residual gastric volumes, increasing the risk of nausea and vomiting. We compared the effects of 1) intrathecal bupivacaine (17.5 mg) and 2) the combination of intrathecal morphine (0.6 mg) and intrathecal bupivacaine (17.5 mg) on the rate of gastric emptying in patients undergoing elective hip arthroplasty. ⋯ The combination of intrathecal morphine (0.6 mg) and intrathecal bupivacaine (17.5 mg) delays gastric emptying postoperatively.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the flexible and standard laryngeal mask airways.
To determine mucosal pressures, ease of insertion, mask position and oropharyngeal leak pressures for the flexible (FLMA) and standard laryngeal mask airway (LMA). ⋯ We conclude that the LMA and FLMA perform similarly in terms of ease of insertion and mask position, but OLP and mucosal pressures are slightly higher for the LMA. Pharyngeal mucosal pressures for both devices are lower than those considered safe for the tracheal mucosa. The overall clinical performance between the two devices is similar.

Comparative Study
Cost-effectiveness of prophylactic dolasetron or droperidol vs rescue therapy in the prevention of PONV in ambulatory gynecologic surgery.
To assess the cost-effectiveness of prophylactic therapy (1.25 mg droperidol or 50 mg dolasetron i.v.) vs no prophylaxis (rescue therapy) for the prevention of post-operative nausea and vomiting (PONV) from a Canadian hospital perspective. ⋯ Dolasetron and droperidol given intraoperatively were more cost-effective than no prophylaxis for PONV in patients undergoing ambulatory gynecologic surgery. The difference between the two agents was small and favoured droperidol. The model was robust to plausible changes through sensitivity analyses.

To present a case of rhabdomyolysis which developed in a child with a known history of Duchenne's muscular dystrophy, following an anesthetic which included sevoflurane. ⋯ Sevoflurane anesthesia has not been shown previously to be associated with the development of acute rhabdomyolysis in a child with a history of Duchenne's muscular dystrophy. As with halothane and isoflurane, the continued use of sevoflurane in the presence of Duchenne's muscular dystrophy should be questioned.
