Randomized Controlled Trial Clinical Trial
Supplemental oxygen does not reduce postoperative nausea and vomiting after thyroidectomy.
Supplemental intra-operative oxygen 80% halves the incidence of nausea and vomiting after open and laparoscopic abdominal surgery, perhaps by ameliorating intestinal ischaemia associated with abdominal surgery. It is unlikely that thyroid surgery compromises intestinal perfusion. We therefore tested the hypothesis that supplemental perioperative oxygen does not reduce the risk of postoperative nausea and vomiting (PONV) after thyroidectomy. ⋯ Supplemental oxygen was ineffective in preventing nausea and vomiting after thyroidectomy, but droperidol reduced the incidence.

Randomized Controlled Trial Multicenter Study Clinical Trial
Randomized prospective study of the analgesic effect of nefopam after orthopaedic surgery.
Balanced postoperative analgesia combines non-narcotic drugs and opioids. We organized a large study to evaluate nefopam analgesia and tolerance in combination with morphine for patient-controlled analgesia (PCA) after orthopaedic surgery. ⋯ In combination with PCA morphine, nefopam gives significant morphine-sparing with lower immediate postoperative pain scores without major side-effects. This analgesic effect seems to be particularly notable for patients with intense preoperative pain.

Randomized Controlled Trial Comparative Study Clinical Trial
Influence of peroperative opioid on postoperative pain after major abdominal surgery: sufentanil TCI versus remifentanil TCI. A randomized, controlled study.
Sufentanil and remifentanil are characterized by two different pharmacokinetic profiles. The aim of this study was to compare the effects of sufentanil and remifentanil administered using target-controlled infusion (TCI) on recovery and postoperative analgesia after major abdominal surgery. ⋯ TCI sufentanil (0.25 ng ml(-1) effect-site concentration at extubation) is more effective than the intraoperative combination of remifentanil TCI infusion with morphine bolus (0.15 mg x kg(-1)) for postoperative pain relief after major abdominal surgery and does not compromise extubation and recovery.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized, controlled, cross-over clinical trial comparing intravenous midazolam sedation with nitrous oxide sedation in children undergoing dental extractions.
The use of benzodiazepines for paediatric dental sedation has received limited attention with regard to research into clinical effectiveness. A study was therefore designed to investigate the use of midazolam, for i.v. sedation in paediatric dental patients. ⋯ I.V. midazolam sedation (0.5 mg x min(-1) to a maximum of 5 mg) appears to be as effective as nitrous oxide sedation in 12-16-yr-old healthy paediatric dental patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of 1% and 2% lidocaine epidural anaesthesia combined with sevoflurane general anaesthesia utilizing a constant bispectral index.
The authors compared the effects of epidural anaesthesia with lidocaine 1% and lidocaine 2% on haemodynamic variables, sevoflurane requirements, and stress hormone responses during surgery under combined epidural/general anaesthesia with bispectral index score (BIS) kept within the range 40-50. ⋯ To maintain BIS of 40-50 during combined epidural/general anaesthesia for lower abdominal surgery, sevoflurane concentrations were lower and less variable with lidocaine 2% than with 1%. In addition, the larger concentration of lidocaine suppressed the stress hormone responses better.
