Randomized Controlled Trial Multicenter Study Comparative Study
Incidence and duration of residual paralysis at the end of surgery after multiple administrations of cisatracurium and rocuronium.
After repeated rocuronium administration there is wide inter-patient variability in the time to recover muscle function.

Randomized Controlled Trial
The effect of positive end expiratory pressure on the respiratory profile during one-lung ventilation for thoracotomy.
Summary In this randomised controlled trial we examined the effects of four different levels of positive end expiratory pressure (PEEP at 0, 5, 8 or 10 cmH(2)O), added to the dependent lung, on respiratory profile and oxygenation during one lung ventilation. Forty-six patients were recruited to receive one of the randomised PEEP levels during one lung ventilation. ⋯ However, the physiological deadspace to tidal volume ventilation ratio was significantly lower in the 8 cmH(2)O PEEP group compared with the other levels of PEEP (p < 0.0001). We concluded that the use of PEEP (< or =10 cmH(2)O) during one lung ventilation does not clinically improve lung compliance, intra-operative or postoperative oxygenation despite a statistically significant reduction in the physiological deadspace to tidal volume ratio.

Randomized Controlled Trial Comparative Study
Midazolam vs ondansetron for preventing postoperative nausea and vomiting: a randomised controlled trial.
We compared the prophylactic anti-emetic efficacy of midazolam and ondansetron in 90 patients scheduled for minor gynaecological (hysteroscopy) or urological (ureteroscopy) procedures planned to last 1-2 h under sevoflurane anaesthesia with spontaneous ventilation of the lungs via a laryngeal mask airway. Midazolam 2 mg or ondansetron 4 mg were administered intravenously 30 min before the end of surgery. ⋯ There were no significant differences in average sedation scores or pain scores. Treatment using ondansetron for anti-emetic prophylaxis did not provide a superior benefit compared to midazolam in the present study.

We describe the use of a questionnaire to define the difficulties in providing anaesthesia in Uganda. The results show that 23% of anaesthetists have the facilities to deliver safe anaesthesia to an adult, 13% to deliver safe anaesthesia to a child and 6% to deliver safe anaesthesia for a Caesarean section. ⋯ Solutions require improvements in local management, finance and logistics, and action to ensure that the importance of anaesthesia within acute sector healthcare is fully recognised. Major investment in terms of personnel and equipment is required to modernise and improve the safety of anaesthesia for patients in Uganda.

Nitrous oxide pollution is common in paediatric anaesthetic practice. A questionnaire was sent to all UK members of the Association of Paediatric Anaesthetists requesting details of three areas of their paediatric practice relating to nitrous oxide: attitudes to its use; current usage; and availability of alternatives. Replies were received from 296 (68%) consultants. ⋯ One hundred and fifty-eight (54%) considered theatre pollution a problem in paediatric anaesthesia. One hundred and sixty-nine (57%) reported that in normal circumstances potential deleterious effects on patients influenced their use of nitrous oxide, whilst only 70 (24%) felt potential effects on staff influenced usage. Fifty-five (18%) felt there should be some restriction in the availability of nitrous oxide.
