Randomized Controlled Trial Multicenter Study
Efficacy of high-fidelity simulation debriefing on the performance of practicing anaesthetists in simulated scenarios.
Research into adverse events in hospitalized patients suggests that a significant number are preventable. The purpose of this randomized, controlled study was to determine if simulation-based debriefing improved performance of practicing anaesthetists managing high-fidelity simulation scenarios. ⋯ We found a modest improvement in performance on a DSC in the debriefed group and overall improvement in both control and debriefed groups using a GRS. Whether this improvement translates into clinical practice has yet to be determined.

Analgesic efficacy of ultrasound-guided transversus abdominis plane block in patients undergoing open appendicectomy.
Transversus abdominis plane (TAP) block is a new regional anaesthetic technique that blocks abdominal neural afferents by introducing local anaesthetic into the neuro-fascial plane between the internal oblique and the transversus abdominis muscles. We evaluated its analgesic efficacy in patients undergoing open appendicectomy in a randomized controlled double-blinded clinical trial. ⋯ Ultrasound-guided TAP block holds considerable promise as a part of a balanced postoperative analgesic regimen for patients undergoing open appendicectomy.

Randomized Controlled Trial Comparative Study
Comparison of ramosetron with ondansetron for prevention of postoperative nausea and vomiting in patients undergoing gynaecological surgery.
Ramosetron is a new selective 5-hydroxytryptamine type 3 (5-HT(3)) receptor antagonist that reportedly has more potent antiemetic effects compared with other 5-HT(3) receptor antagonists. The purpose of this study was to evaluate the efficacy of ramosetron for the prevention of postoperative nausea and vomiting (PONV) with that of ondansetron or placebo in high-risk patients undergoing gynaecological surgery. ⋯ Ramosetron 0.3 mg i.v. was as effective as ondansetron 8 mg i.v. in decreasing the incidence of PONV and reducing nausea severity in female patients during the first 24 h after gynaecological surgery.

Magnesium sulphate attenuates arterial pressure increase during laparoscopic cholecystectomy.
Magnesium is well known to inhibit catecholamine release and attenuate vasopressin-stimulated vasoconstriction. We investigated whether i.v. magnesium sulphate attenuates the haemodynamic stress responses to pneumoperitoneum by changing neurohumoral responses during laparoscopic cholecystectomy. ⋯ I.V. magnesium sulphate before pneumoperitoneum attenuates arterial pressure increases during laparoscopic cholecystectomy. This attenuation is apparently related to reductions in the release of catecholamine, vasopressin, or both.

Randomized Controlled Trial Multicenter Study
Cognitive aid for neonatal resuscitation: a prospective single-blinded randomized controlled trial.
Retention of skills and knowledge after neonatal resuscitation courses (NRP) is known to be problematic. The use of cognitive aids is mandatory in industries such as aviation, to avoid dependence on memory when decision-making in critical situations. We aimed to prospectively investigate the effect of a cognitive aid on the performance of simulated neonatal resuscitation. ⋯ Retention of skills after NRP training is poor. The infrequent use of the cognitive aid may be the reason that it did not improve performance. Further research is required to investigate whether cognitive aids can be useful if their use is incorporated into the NRP training.
