Randomized Controlled Trial Clinical Trial
Effect of parecoxib, a novel intravenous cyclooxygenase type-2 inhibitor, on the postoperative opioid requirement and quality of pain control.
The analgesic efficacy and side effect profile of intravenous parecoxib, a novel cyclooxygenase type-2 (COX-2) inhibitor, was assessed in a double-blinded, placebo-controlled study involving patients undergoing major gynecologic surgical procedures. ⋯ Intravenous parecoxib (20 or 40 mg) was effective in decreasing the PCA opioid requirement after lower abdominal surgical procedures. However, it failed to improve pain management or reduce opioid-related side effects in the early postoperative period.

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 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
The epidural "top-up": predictors of increase of sensory blockade.
Extension of sensory blockade after an epidural top-up in combined spinal epidural (CSE) anesthesia is partly attributed to compression of the dural sac by the injected volume. This study investigated whether a volume effect plays a significant role when administering an epidural top-up after an initial epidural loading dose and assessed the predictive value of different factors with respect to the increase in sensory blockade. ⋯ When using epidural ropivacaine, the extension of sensory blockade after administering an epidural top-up is caused by a local anesthetic effect and not by a volume effect. Under the conditions of this study, predictors of the increase in sensory blockade are the presence of ropivacaine in the top-up injectate, the number of segments blocked at the time of epidural top-up, and gender.

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.
