Randomized Controlled TrialDesflurane consumption with automated vapor control systems in two different anaesthesia machines. A randomized controlled study.
In general anaesthesia practice a fresh gas flow (FGF) of ≥0.5 L/min is usually applied. Automated gas delivery devices are developed to reduce volatile anaesthetic consumption by limiting gas flow. This study aimed to compare desflurane consumption between automated gas control devices compared to conventional low flow anaesthesia in the Flow-I and Aisys anaesthesia machines, and to compare desflurane consumption between the two automated gas delivery devices. We hypothesised that desflurane consumption would be lower with automated gas delivery compared to conventional low flow anaesthesia, and that desflurane consumption could differ between the different gas delivery devices. ⋯ Under clinical conditions, we found a reduction in desflurane consumption when using automated gas delivery devices compared to conventional low flow anaesthesia. Both devices were reliable in use.

Randomized Controlled TrialMidazolam versus dexamethasone-ondansetron in preventing postoperative nausea-vomiting in patients undergoing laparoscopic surgeries.
Midazolam reduces post-operative nausea and vomiting (PONV) when compared to a placebo or when used as an adjuvant to other antiemetics. The present study was designed to compare midazolam with a combination of dexamethasone-ondansetron in preventing PONV. ⋯ Midazolam does not result in significantly different frequency of PONV than a combination of dexamethasone-ondansetron.
