BACKGROUND The aim of the study was to evaluate the effect of lornoxicam (L) on sensory and motor block onset time, tourniquet pain, and postoperative analgesia, when added to lidocaine in intravenous regional anaesthesia (IVRA). METHODS Forty-five patients undergoing hand surgery were randomly and blindly divided into three groups as to receive either i.v. saline and IVRA with lidocaine 0.5%...

BACKGROUND Electrical stimulation of peripheral nerves produces acute analgesic effects. This randomized, sham-controlled, crossover study was designed to evaluate the effect of differing durations of electrical stimulation on the analgesic response to percutaneous electrical nerve stimulation in 75 consenting patients with low back pain. METHODS All patients received electrical stimulation f...

BACKGROUND Cyclooxygenase 2 inhibition has proven analgesic efficacy in a variety of surgical procedures. We postulated that perioperative cyclooxygenase 2 inhibition significantly reduces postoperative morphine requirements after major thoracic surgery and investigated the site of this potential analgesic effect. METHODS Ninety-two patients participated in this single-center, double-blind, r...

Three studies demonstrated that postsuppressional rebound (PSR) may be both reduced and enhanced by manipulating people's attributions about why they experience difficulty during suppression. Telling participants that suppression failures indicate a high motivation to use the suppressed construct produced more PSR than telling them that suppression failures indicate a low motivation to use the ...

We randomised 50 patients with extracapsular fractures of the femoral neck to receive either a bupivacaine femoral nerve block or systemic analgesia alone. A femoral nerve block was found to be an easy and effective procedure which significantly reduced perioperative analgesic requirements and postoperative morbidity.

Previous studies have suggested that ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, provides a pre-emptive analgesic effect and pre-emptive analgesia improves postoperative pain management. The aim of this study was to determine the effict of pre-incisional vs. post-incisional intravenous low dose of racemic ketamine in postoperative pain in children undergoing inguinal hernia re...
