Randomized Controlled Trial
Haloperidol dose combined with dexamethasone for PONV prophylaxis in high-risk patients undergoing gynecological laparoscopic surgery: a prospective, randomized, double-blind, dose-response and placebo-controlled study.
Low-dose haloperidol is known to be effective for the prevention of postoperative nausea and vomiting (PONV). However, precise dose-response studies have not been completed, especially in patients at high risk for PONV who require combination therapy. This study sought to identify which dose of haloperidol 1mg or 2mg could be combined with dexamethasone without adverse effects in high-risk patients undergoing gynecological laparoscopic surgery. ⋯ For high-risk PONV patients undergoing gynecological laparoscopic surgery, when used with dexamethasone, 1-mg haloperidol was equally effective as 2 mg in terms of preventing PONV with the less sedative effect.

Randomized Controlled Trial
Appropriate sevoflurane concentration to stabilize autonomic activity during intubation with rocuronium in infants: a randomized controlled trial.
In infants, sevoflurane is commonly used for induction of anesthesia, following which a muscle relaxant is administered to facilitate tracheal intubation. When rocuronium is used as the muscle relaxant, intubation may be performed before reaching an adequate depth of anesthesia because of its rapid onset. The purpose of this study was to investigate the optimal sevoflurane concentration that would minimize the impact of intubation on hemodynamics and autonomic nervous system (ANS) activity in infants. ⋯ Sympathomimetic and parasympatholytic responses to intubation in the E'Sevo-3% group were much greater than those in the E'Sevo-5% group. During tracheal intubation in infants, 4% or 5% sevoflurane is appropriate for prevention of sympathetic hyperactivation and maintenance of ANS balance as compared to 3% sevoflurane, when a muscle relaxant is co-administered.

Randomized Controlled Trial Comparative Study
Effects of propofol versus thiopental on Apgar scores in newborns and peri-operative outcomes of women undergoing emergency cesarean section: a randomized clinical trial.
General and regional anesthesia are the two main techniques used in cesarean section. Regional anesthesia is preferred, but under certain circumstances, such as by patient request and in patients with back deformities, general anesthesia is the only option. Commonly used induction agents include thiopental, ketamine, and propofol, depending on availability and the maternal clinical condition. The objective of this study was to investigate the effects of thiopental and propofol on the neonatal Apgar score and maternal recovery time following emergency cesarean section in order to determine the superior agent for mothers and neonates. ⋯ Apgar scores do not differ significantly whether thiopental or propofol is used for anesthetic induction in women undergoing general anesthesia for an emergency cesarean section.

Meta Analysis
Meta-analysis of the cardioprotective effect of sevoflurane versus propofol during cardiac surgery.
To evaluate the cardioprotective effects of sevoflurane versus propofol anesthesia in patients undergoing cardiac surgery. ⋯ Sevoflurane may exhibit a more favorable cardioprotective effect during cardiac surgery than propofol.

Randomized Controlled Trial
A repeated measures, randomised cross-over trial, comparing the acute exercise response between passive and active sitting in critically ill patients.
Early mobilisation of critically ill patients is safe and beneficial, but the metabolic cost of exercise remains unquantified. This study compared the acute exercise response in critically ill participants during passive and active sitting. ⋯ Sitting on the edge of the bed is a more metabolically demanding activity than a passive chair transfer in critically ill patients.
