Randomized Controlled Trial Clinical Trial
Continuous infraclavicular brachial plexus block for postoperative pain control at home: a randomized, double-blinded, placebo-controlled study.
This randomized, double-blinded, placebo-controlled study investigated the efficacy of patient-controlled regional analgesia using an infraclavicular brachial plexus perineural catheter and a portable infusion pump for outpatients undergoing moderately painful, upper extremity orthopedic surgery. ⋯ After moderately painful orthopedic surgery of the upper extremity, ropivacaine infusion using a portable, mechanical pump and an infraclavicular brachial plexus perineural catheter at home decreased pain, sleep disturbances, narcotic use and related side effects, and improved overall satisfaction.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of electrophysiologic effects of propofol and isoflurane-based anesthetics in children undergoing radiofrequency catheter ablation for supraventricular tachycardia.
Radiofrequency catheter ablation (RFCA), which is typically performed with general anesthesia in children, is an interventional therapy for tachyarrhythmia. Although the electrophysiologic (EP) effects of isoflurane- and propofol-based anesthetics have been shown to be similar, a retrospective analysis reported significantly longer RFCA procedural duration with the use of isoflurane. It remains unclear whether the ability to successfully perform RFCA differs between these drugs. ⋯ Isoflurane- and propofol-based anesthesia were equally suitable in children and adolescents undergoing RFCA.

Randomized Controlled Trial Clinical Trial
Dexamethasone in combination with dolasetron for prophylaxis in the ambulatory setting: effect on outcome after laparoscopic cholecystectomy.
Postoperative nausea and vomiting after laparoscopic cholecystectomy remains a common problem despite routine antiemetic prophylaxis. Therefore, the authors investigated the effect of administering 4 mg intravenous dexamethasone as an adjunct to a 5-HT3 antagonist (12.5 mg intravenous dolasetron) with respect to patient outcome. ⋯ The authors conclude that the adjunctive use of 4 mg intravenous dexamethasone shortened the time to achieve discharge criteria and improved the quality of recovery and patient satisfaction scores after laparoscopic cholecystectomy procedures in outpatients receiving prophylaxis with 12.5 mg intravenous dolasetron.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled regional analgesia (PCRA) at home: controlled comparison between bupivacaine and ropivacaine brachial plexus analgesia.
The aim of this randomized, double-blinded study was to compare the analgesic efficacy of bupivacaine versus ropivacaine brachial plexus analgesia after ambulatory hand surgery. An additional aim was to study the feasibility and safety of patient-controlled regional analgesia (PCRA) outside the hospital. ⋯ This double-blinded study has demonstrated the feasibility of self-administration of local anesthetic to manage postoperative pain outside the hospital. Ropivacaine and bupivacaine provided effective analgesia, and patient satisfaction with PCRA was high. Patient selection, follow-up telephone call, and 24-h access to anesthesiology services are prerequisites for PCRA at home.

Randomized Controlled Trial Clinical Trial
Dexamethasone prolongs local analgesia after subcutaneous infiltration of bupivacaine microcapsules in human volunteers.
The addition of small amounts of dexamethasone to extended-release formulations of bupivacaine in microcapsules has been found to prolong local analgesia in experimental studies, but no clinical data are available. ⋯ Addition of small amounts of dexamethasone to bupivacaine incorporated in microcapsules prolonged local analgesia compared with microcapsules with plain bupivacaine after subcutaneous administration in humans.
