Randomized Controlled Trial
Effect of oral gabapentin on postoperative epidural analgesia.
Gabapentin has been used successfully as a non-opioid analgesic adjuvant for postoperative pain management. We hypothesized that gabapentin might be a useful adjuvant for postoperative analgesia provided with patient-controlled epidural analgesia (PCEA). ⋯ Oral gabapentin (1.2 g day(-1)) as an adjunct to epidural analgesia decreased pain and analgesic consumption. Despite an increased incidence of dizziness it also increased patient satisfaction.

Randomized Controlled Trial
Effects of three different dose regimens of magnesium on propofol requirements, haemodynamic variables and postoperative pain relief in gynaecological surgery.
In this double-blind, randomized, placebo-controlled study we compared the effects of three different dose regimens of magnesium on intraoperative propofol and atracurium requirements, and postoperative morphine consumption in patients undergoing gynaecological surgery. ⋯ Magnesium 40 mg kg(-1) bolus followed by 10 mg kg(-1) h(-1) infusion leads to significant reductions in intraoperative propofol, atracurium and postoperative morphine consumption. Increasing magnesium dosage did not offer any advantages, but induced haemodynamic consequences.

Randomized Controlled Trial Comparative Study
Bougie-guided insertion of the ProSeal laryngeal mask airway has higher first attempt success rate than the digital technique in children.
We tested the hypothesis that bougie-guided insertion of the ProSeal laryngeal mask airway (ProSeal LMA) has higher success rate than the digital technique in children. ⋯ We conclude that bougie-guided insertion of the ProSeal LMA has a higher first attempt success rate than the digital technique in children.

Randomized Controlled Trial
Changes in the effect of propofol in response to altered plasma protein binding during normothermic cardiopulmonary bypass.
During normothermic cardiopulmonary bypass (CPB), the effect on propofol pharmacokinetics of changes in its binding to plasma proteins is consistent with the predictions of the well-stirred model of hepatic elimination for nonrestrictively cleared drug. However, whether changes in binding lead to clinically significant changes in the drug effect remains unclear. The purpose of this study was to assess changes in the drug effect of propofol in response to altered plasma binding using quantitative EEG measurements. ⋯ The anaesthetic effect of propofol significantly increased during CPB without any alteration in the total drug concentration. The enhanced efficacy may be caused by a reduction in plasma binding of the drug.
