Randomized Controlled Trial Comparative Study Clinical Trial
Epidural block for obstetrics: comparison of bolus injection of local anesthetic with gravity flow technique.
To test the hypothesis that slow administration of local anesthetic into the epidural space by gravity flow reduces the incidence of signs and symptoms of unintended injection. ⋯ Gravity flow administration of local anesthetic-opioid solution during epidural block for obstetrics was associated with fewer signs of systemic drug absorption and cardiovascular perturbations than was the traditional bolus injection. This study supports the current opinion that slow administration of local anesthetic during epidural block contributes to fewer adverse events.

Randomized Controlled Trial Clinical Trial
Spontaneous movements associated with rocuronium injection: the effects of prior administration of fentanyl.
To determine if prior injection of fentanyl decreases the incidence of spontaneous movements during rocuronium administration. ⋯ Prior injection of fentanyl significantly decreases the incidence of spontaneous movements associated with rocuronium administration.

Randomized Controlled Trial Clinical Trial
Combined popliteal and posterior cutaneous nerve of the thigh blocks for short saphenous vein stripping in outpatients: an alternative to spinal anesthesia.
To compare a combination of peripheral nerve blocks with spinal anesthesia in ambulatory patients undergoing short saphenous vein stripping. ⋯ The combination of popliteal and posterior cutaneous nerve of the thigh blocks provided adequate anesthesia and a faster recovery profile with a similar subjective acceptance of both anesthetic techniques in ambulatory patients undergoing short saphenous vein stripping in the prone position.

Randomized Controlled Trial Clinical Trial
A randomized, double-blind, placebo controlled comparison of droperidol, ondansetron, and metoclopramide for the prevention of vomiting following outpatient strabismus surgery in children.
To compare the efficacy of ondansetron, droperidol, or metoclopramide with placebo in preventing postoperative vomiting following strabismus surgery. ⋯ While both ondansetron and droperidol are more effective than metoclopramide when compared with placebo in decreasing the incidence of predischarge vomiting, none of these drugs was more effective than placebo in decreasing the incidence of postdischarge vomiting. Recovery from anesthesia was not significantly different among the groups as assessed by time to awakening, initial Steward score, and time to discharge.

Randomized Controlled Trial Clinical Trial
Total-body oxygen consumption after isoflurane anesthesia: effects of mild hypothermia and combined epidural-general anesthesia.
To determine the effects of epidural anesthesia and avoidance of intraoperative heat loss on the increase in total-body oxygen consumption in the immediate postoperative period after major intraabdominal surgery. ⋯ Total-body VO2 was increased in the immediate postoperative period. After general anesthesia, the magnitude of the increase in VO2 was significantly less in normothermic patients than in hypothermic patients. After combined epidural-general anesthesia, VO2 was increased in normothermic and in hypothermic patients.
