A case of recurarization in the recovery room is reported. Accumulation of atracurium in the intravenous line led to recurarization after flushing the line in the recovery room. A respiratory arrest with severe desaturation and bradycardia occurred. Circumstances leading to this event and the mechanisms enabling a neuromuscular blockade to occur, following the administration of a small dose of relaxant, are discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Prophylactic therapy with combined granisetron and dexamethasone for the prevention of post-operative vomiting in children.
This study was undertaken to compare the efficacy and safety of granisetron, a 5-hydroxytryptamine type 3 receptor antagonist, and dexamethasone and each drug alone for the prevention of post-operative vomiting by children, with no history of motion sickness and/or previous post-operative vomiting, undergoing general inhalational anaesthesia for surgery (inguinal hernia and phimosis). In a randomized, double-blind manner, 150 children, ASA physical status 1, aged 4-10 years, were assigned to receive granisetron 40 mg kg-1, dexamethasone 150 mg kg-1, or granisetron 40 mg kg-1 plus dexamethasone 150 mg kg-1 intravenously immediately after inhalation induction of anaesthesia (n = 50 of each). ⋯ No clinically serious adverse events were observed in any of the groups. In conclusion, prophylactic therapy with combined granisetron and dexamethasone was more effective than was each anti-emetic alone for the prevention of vomiting after paediatric surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of ondansetron and tropisetron combined with droperidol for the prevention of emesis in women with a history of post-operative nausea and vomiting.
The anti-emetic efficacy of prophylactic ondansetron and tropisetron in combination with a low dose of droperidol in patients with high probability for post-operative nausea and vomiting undergoing gynaecological laparoscopy was compared. Patients were randomly allocated in a double-blind manner to receive either ondansetron 8 mg (n = 45) or tropisetron 5 mg (n = 43) at the end of surgery. A standardized general anaesthetic technique was used, including droperidol 0.75 mg. ⋯ The onset time for rescue medication was significantly sooner after tropisetron than ondansetron (3 h 18 min vs. 6 h 25 min; P = 0.007). There were no statistically significant differences in efficacy between prophylactic ondansetron and tropisetron combined with droperidol in a high-risk population. However, ondansetron appeared to be more effective in preventing post-operative nausea and vomiting in the early hours after surgery compared with tropisetron.

The effects of bolus and infusion doses of propofol on histopathological changes in the rat pancreas are reported. After obtaining Hospital Ethics Committee approval, 75 female Wistar rats were assigned to three study groups. Groups I (n = 30) and II (n = 30) received 10 mg kg-1 intravenous bolus of propofol; with propofol administered to group II at an infusion rate of 10 mg kg-1 h-1 for 30 min immediately after the bolus doses. ⋯ The pancreatic tissues of group I were normal. The incidence of acute pancreatitis in each of the groups was not significant. It is therefore suggested that, further controlled studies are needed to investigate the relation between pancreatitis and the use of propofol.
