Randomized Controlled Trial Clinical Trial
Preoperative combined with intraoperative skin-surface warming avoids hypothermia caused by general anesthesia and surgery.
To evaluate the effects of intraoperative skin-surface warming with and without 1 hour of preoperative warming, in preventing intraoperative hypothermia, and postoperative hypothermia, and shivering, and in offering good conditions to early tracheal extubation. ⋯ One hour of preoperative warning combined with intraoperative skin-surface warming, not simply intraoperative warming alone, avoided hypothermia caused by general anesthesia during the first two hours of surgery. Both methods prevented postoperative hypothermia and shivering and offered good conditions for early tracheal extubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative epidural anesthesia and postoperative analgesia with levobupivacaine for major orthopedic surgery: a double-blind, randomized comparison of racemic bupivacaine and ropivacaine.
To compare the onset time and duration of epidural anesthesia, and the quality of postoperative analgesia produced by levobupivacaine, racemic bupivacaine, and ropivacaine. ⋯ Levobupivacaine 0.5% produces an epidural block of similar onset, quality, and duration as the one produced by the same volume of 0.5% bupivacaine, with a motor block deeper than that produced by 0.5% ropivacaine. When prolonging the block for the first 12 hours after surgery with a patient-controlled epidural infusion, 0.125% levobupivacaine provides adequate pain relief after major orthopedic surgery, with similar recovery of motor function as compared with 0.125% bupivacaine and 0.2% ropivacaine.

Randomized Controlled Trial Comparative Study Clinical Trial
Hemodynamic and catecholamine response to tracheal intubation: direct laryngoscopy compared with fiberoptic intubation.
To compare the stress response following tracheal intubation using direct laryngoscopy to that using fiberoptic bronchoscopy technique. ⋯ The use of either direct laryngoscopy or fiberoptic bronchoscopy produces a comparable stress response to tracheal intubation. Catecholamine levels do not correlate with the hemodynamic changes.

Randomized Controlled Trial Comparative Study Clinical Trial
Sevoflurane requirements during coloproctologic surgery: difference between two different epidural regimens.
To examine the influence of epidural morphine on the end-tidal sevoflurane concentration titrated to maintain bispectral index (BIS) values between 40 and 50. ⋯ Adding morphine to the bupivacaine epidural solution did not reduce sevoflurane requirements but did provide high-quality postoperative analgesia, mainly just after tracheal extubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Risk of recurarization during retransfusion of autologous blood withdrawn after injection of muscle relaxants: a comparison of rocuronium and mivacurium.
In the context of acute normovolemic hemodilution (ANH) recurarization, defined as significant decrease of train-of-four ratio (TOFR) during retransfusion of autologous blood withdrawn after induction of anesthesia, has been described for vecuronium and atracurium. The present study for the first time examined this risk for rocuronium and mivacurium. ⋯ Recurarization during retransfusion may occur with both neuromuscular blocking drugs, mivacurium and rocuronium, when these drugs were injected before the removal of the autologous blood.
