Randomized Controlled TrialDexamethasone before total laparoscopic hysterectomy: a randomized controlled dose-response study.
A prospective, randomized, double blind, placebo-controlled study was undertaken to evaluate the efficacy of a single preoperative dose of dexamethasone, in different dosages, in providing postoperative analgesia in patients undergoing total laparoscopic hysterectomy (TLH). ⋯ Dexamethasone at a dose of 8 mg given intravenously 2 h before induction, delays patient request for analgesia and reduces total fentanyl consumption and PONV in patients undergoing TLH.

Randomized Controlled Trial Comparative StudyComparison of 0.25% levobupivacaine and 0.25% bupivacaine for posterior approach interscalene brachial plexus block.
This study compares the onset time and quality of posterior approach interscalene brachial plexus block produced by 0.25% levobupivacaine and 0.25% bupivacaine. ⋯ We conclude that 0.25% levobupivacaine and 0.25% bupivacaine have similar motor and sensory block onset times and qualities when used in posterior approach interscalene brachial plexus block, and provide comfortable anesthesia and analgesia for shoulder surgery.

Randomized Controlled TrialKetamine eliminates propofol pain but does not affect hemodynamics during induction with double-lumen tubes.
Propofol injection during induction of anesthesia induces pain. Ketamine has been shown to reduce the injection pain. However, ketamine has unfavorable adverse effects, including increased secretion production and hemodynamic responses, which might induce pulmonary or hemodynamic adverse events, especially in patients undergoing lung surgery who require a double-lumen tube (DLT). The aim of this study was to determine whether ketamine can safely reduce propofol injection pain during induction of anesthesia for lung surgery. ⋯ One milligram per kilogram of ketamine completely eliminated pain associated with propofol injection without affecting hemodynamics during induction of anesthesia and oxygenation during OLV.
