Randomized Controlled Trial Clinical Trial
Effect of epidural morphine on sedation requirements during regional anesthesia.
To examine the effect of using analgesic doses of epidural morphine on midazolam requirements for conscious sedation during regional anesthesia. ⋯ An analgesic dose of epidural morphine, after a latent period of 3 hours, may decrease the dose of midazolam required for sedation using regional anesthesia.

Randomized Controlled Trial Clinical Trial
Respiratory effects of sevoflurane used in combination with nitrous oxide and surgical stimulation.
To evaluate the respiratory effects of sevoflurane anesthesia with and without nitrous oxide (N2O) during surgical stimulation. ⋯ Sevoflurane administered at an appropriate anesthetic depth maintained spontaneous respiration at acceptable levels during surgical stimulation, especially when combined with N2O.

Randomized Controlled Trial Clinical Trial
Effects of alkalinization of lidocaine on the pain of skin infiltration and intravenous catheterization.
To test the hypothesis that alkalinization of lidocaine decreases the pain of skin infiltration in surgical patients. ⋯ Pain resulting from skin infiltration of lidocaine solutions can be diminished by adding NaHCO3. However, catheter size is more important than the presence or absence of NaHCO3 in determining the pain of i.v. catheterization.

Randomized Controlled Trial Comparative Study Clinical Trial
Recovery following outpatient anesthesia: use of enflurane versus propofol.
To compare the intraoperative conditions and postoperative recovery of patients following the use of either propofol-nitrous oxide (N2O) or enflurane-N2O for maintenance of outpatient anesthesia. ⋯ Induction of anesthesia with propofol is associated with a more rapid emergence from anesthesia than induction with thiopental. Maintenance of anesthesia with enflurane did not prolong recovery compared with maintenance with propofol, but enflurane was associated with increased frequency of postoperative nausea and vomiting.
