Randomized Controlled Trial Comparative StudyA randomized comparison of long-axis and short-axis imaging for in-plane ultrasound-guided popliteal-sciatic perineural catheter insertion.
Ultrasound-guided long-axis in-plane sciatic perineural catheter insertion has been described but not validated. For the popliteal-sciatic nerve, we hypothesized that a long-axis in-plane technique, placing the catheter parallel and posterior to the nerve, results in faster onset of sensory anesthesia compared to a short-axis in-plane technique. ⋯ Long-axis in-plane popliteal-sciatic perineural catheter insertion requires more time to perform compared to a short-axis in-plane technique without demonstrating any advantages.

Randomized Controlled TrialIntravenous dezocine pretreatment reduces the incidence and intensity of myoclonus induced by etomidate.
To evaluate the suppressive effect of intravenous dezocine on the incidence and severity of myoclonic movements induced by etomidate, a total of 80 patients, American Society of Anesthesiologists physical status I-II, were randomized into two equally sized groups (n = 40). These two groups were assigned to give either intravenous dezocine 0.1 mg/kg or a matching placebo (equal volume of 0.9% saline) 30 s before administration of etomidate. ⋯ Pretreatment with dezocine significantly reduced both the incidence and intensity of myoclonus. These results demonstrate that intravenous dezocine 0.1 mg/kg 30 s prior to induction was effective in suppressing myoclonic movements in our patients.

Randomized Controlled Trial Comparative StudyComparison of cognitive, ambulatory, and psychomotor recovery profiles after day care anesthesia with propofol and sevoflurane.
We compared the recovery profile of propofol and sevoflurane when used for maintenance of anesthesia in elective day care operative procedures. ⋯ Recovery from sevoflurane anesthesia, especially with regard to cognitive functions, may be slightly faster than from propofol, but the difference is not sufficiently significant to affect the time to "home-readiness" in patients undergoing day care surgery.

Randomized Controlled Trial Comparative StudyPretreatment with remifentanil, fentanyl, or lidocaine to prevent withdrawal after rocuronium using venous occlusion technique in children and adolescents: a prospective randomized placebo-controlled double-blind study.
Pain caused by intravenous injection of the muscle relaxant rocuronium bromide is common in children and adolescents. The cause of this unwanted effect is still unclear, and different pretreatment drugs have been administered in attempts to alleviate this side effect, with varying degrees of success. ⋯ Using a venous occlusion technique for 60 s, lidocaine was found to be most effective in preventing the withdrawal effect caused by rocuronium injection in children and adolescents. Lidocaine was superior to remifentanil which, in turn, was more effective than fentanyl.

Randomized Controlled TrialEffect of pre-warmed intravenous fluids on perioperative hypothermia and shivering after ambulatory surgery under monitored anesthesia care.
The aim of this study was to evaluate the effects of pre-warmed (approximately 41 °C) intravenous fluids (IV) on perioperative hypothermia and postoperative shivering in female patients undergoing short, ambulatory urological surgery under monitored anesthesia care (MAC). ⋯ Infusion of pre-warmed IV fluid improved the postoperative recovery profile by decreasing hypothermia and shivering in female patients undergoing short, ambulatory urological surgery under MAC.
