Randomized Controlled TrialEmulsion of flurbiprofen axetil reduces propofol injection pain due to a decrease in free propofol concentration.
Flurbiprofen axetil emulsion (FA), a prodrug of nonsteroidal anti-inflammatory drugs (NSAIDs) that is widely used for perioperative pain relief in Japan, has been effective for reducing propofol injection pain, but the mechanism is unclear. The purpose of this study was to test the hypothesis that the reduction of propofol injection pain by FA may be attributed to a decrease in free propofol concentration. ⋯ The findings suggest that the reduction of propofol injection pain by FA may be explained, at least in part, by a reduction in the free propofol concentration.

Randomized Controlled Trial Comparative StudyLornoxicam and ondansetron for the prevention of intrathecal fentanyl-induced pruritus.
In this randomized, double-blind study, we aimed to compare the effectiveness of lornoxicam and ondansetron for the prevention of intrathecal fentanyl-induced pruritus in patients undergoing cesarean section. ⋯ We observed that the administration of 8 mg IV lornoxicam failed to prevent intrathecal fentanyl-induced pruritus in parturients. Also, our data confirmed that ondansetron is likely to attenuate intrathecal fentanyl-induced pruritus.

Cerebral injury following cardiac surgery continues to be a significant source of morbidity and mortality after cardiac surgery. A spectrum of injuries ranging from subtle neurocognitive dysfunction to fatal strokes are caused by a complex series of multifactorial mechanisms. Protecting the brain from these injuries has focused on intervening on each of the various etiologic factors. Although numerous studies have focused on a pharmacologic solution, more success has been found with nonpharmacologic strategies, including optimal temperature management and reducing emboli generation.

Randomized Controlled TrialEpidural ropivacaine infusion for the treatment of pain following axillary muscle-sparing thoracotomy: a dose-evaluation study.
We aimed to investigate the optimal dose of continuous epidural ropivacaine for effective analgesia with minimal side effects after axillary muscle-sparing thoracotomy. ⋯ Our results showed that epidural analgesia using ropivacaine, at 12 mg x h(-1), provided the best analgesia with few side effects.

Randomized Controlled Trial Comparative StudyThe analgesic efficacy of two different approaches to the lumbar plexus for patient-controlled analgesia after total knee replacement.
This study assessed the efficacy of a patient-controlled regional analgesia technique for either psoas compartment block or femoral nerve block after total knee replacement in 68 patients who were randomly divided into these two groups. All patients received 40 ml of 0.25% bupivacaine via femoral or psoas catheters before general anesthesia, and then, as patient-controlled regional analgesia, 10-ml boluses of 0.125% bupivacaine, with a lockout time of 60 min over 48 h. ⋯ All measured parameters were comparable in the two groups. Both techniques achieved a good quality of analgesia and satisfaction without any major side effect.
