Case ReportsUltrasound-aided unilateral epidural block for single lower-extremity pain.
We report an ultrasound-aided unilateral epidural block, employed in two patients, to provide better analgesia and motor function for lower-extremity pain. The patient in case 1 was a 72-year-old woman who suffered pain arising from Herpes zoster rash on the left leg (the second lumbar nerve area). A left-dominant continuous unilateral epidural block was performed to reduce her pain. ⋯ His left knee pain was clearly reduced, with partial paralysis, but motor function in his right leg was completely normal during the continuous epidural block with 4 ml h(-1) of 0.2% ropivacaine. Ultrasound imaging around the epidural space facilitated effective unilateral epidural block for single lower-extremity pain in both patients. This technique could decrease possible side effects and improve patient satisfaction during continuous nerve block by maintaining motor function and sensation in the nondependent side.

Randomized Controlled Trial Comparative StudyA comparison of intra-articular magnesium and/or morphine with bupivacaine for postoperative analgesia after arthroscopic knee surgery.
Both magnesium and morphine provide enhanced patient analgesia after arthroscopic knee surgery when administered separately via the intra-articular route. Magnesium sulfate amplifies the analgesic effect of morphine. This study was designed to compare the analgesic effects of intra-articular magnesium and morphine, with bupivacaine, when used separately and in combination. ⋯ Intra-articular administration of magnesium sulfate or morphine, with bupivacaine, had comparable analgesic effects in the doses used. Their combination provided more effective postoperative analgesia than either drug alone.

Randomized Controlled TrialPriming with rocuronium or vecuronium prevents remifentanil-mediated muscle rigidity and difficult ventilation.
The aim of this study was to test our hypothesis that priming with rocuronium would prevent muscle rigidity and difficult ventilation due to remifentanil administration. ⋯ The present study showed that priming with rocuronium or vecuronium reduced the incidence of difficult ventilation by avoiding the muscle rigidity caused by remifentanil.

Randomized Controlled TrialPostoperative analgesic effect of preoperative intravenous flurbiprofen in arthroscopic rotator cuff repair.
This study was carried out to evaluate the postoperative analgesic effects of preoperative intravenous flurbiprofen in patients undergoing arthroscopic rotator cuff repair under general anesthesia. ⋯ These results show that preoperative intravenous flurbiprofen facilitates the analgesic effect in the early postoperative period after arthroscopic rotator cuff repair.
