Randomized Controlled Trial
The effect of preoperative suggestions on perioperative dreams and dream recalls after administration of different general anesthetic combinations: a randomized trial in maxillofacial surgery.
A significant proportion of patients experience recallable dreams during anaesthesia, apparently higher with propofol induction & maintenance, and when pre-induction psychological suggestion is used.

Randomized Controlled Trial
Effect of magnesium sulphate on bi-spectral index (BIS) values during general anesthesia in children.
Magnesium was reported to reduce both the anesthetic requirements and the period needed to reach a bi-spectral index value of 60 when used intra-operatively (Br J Anaesth 83:302-20, 1999; Anesth Analg 20:1273-5, 1988; Br J Anaesth 89:594-8, 2002; Anesth Analg 87:206-10, 1998; Br J Anaesth 89:594-8, 2002; Br J Anaesth 94:438-41, 2005) and to minimize the emergence agitation (Anaesthesia 61:1058-63, 2006). Previous studies examined the influence of magnesium on the anesthetic requirements while the bi-spectral Index values were kept within a constant range. We evaluated the effect of intraoperative magnesium on the bi-spectral index values during pediatric anesthesia while we kept other anesthetic variables unchanged. ⋯ Magnesium produced significantly lower BIS values, less time to reach BIS values below 60, lower tidal volume and lower respiratory rate during pediatric general anesthesia.

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.

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.
