BACKGROUND AND OBJECTIVES We hypothesized that ultrasound-guided wrist blocks may be faster to perform, and may increase success rate, compared with nerve stimulation-guided wrist blocks. METHODS Sixty patients undergoing ambulatory endoscopic carpal tunnel release were randomly allocated to receive median and ulnar nerve blocks using either sensory-motor(More)
BACKGROUND Efficacy of continuous perineural and patient-controlled ropivacaine infusion at home after orthopedic surgery was compared with patient-controlled intravenous morphine for functional recovery and postoperative analgesia in a multicenter randomized trial. METHODS Eighty-three patients scheduled to undergo acromioplasty or hallux valgus surgery(More)
UNLABELLED A computed tomographic scan was obtained in 35 patients to measure the depth and the relationship of the branches of the lumbar plexus to the posterior superior iliac spine projection and the vertebral column. In addition, we prospectively studied 80 patients scheduled for total hip arthroplasty who received a continuous psoas compartment block(More)
BACKGROUND AND OBJECTIVES This prospective study compared the efficacy and adverse effects after knee surgery of ropivacaine 0.2% administered as patient-controlled femoral analgesia (PCFA), as a continuous femoral infusion (Inf), or as both (PCFA+Inf). METHODS Before general anesthesia, 140 adults scheduled to undergo major knee surgery received a(More)
BACKGROUND AND OBJECTIVES Because the median nerve at the wrist has mainly sensory endings, the aim of this study was to assess the response of the median nerve to nerve stimulation at the wrist and to evaluate the quality of median nerve block. A control group of patients who received blinded injections was analyzed and compared post hoc. METHODS One(More)
BACKGROUND AND OBJECTIVES Stimulating perineural catheters are developed to overcome technical problems of nonstimulating catheters, but their efficacy remains controversial. However, no volume-response study has compared success rates between stimulating and nonstimulating catheters. This study of stimulating versus nonstimulating catheters compares the(More)
OBJECTIVE Describe early discharge of patients treated with continuous perineural analgesia after orthopaedic surgery. METHODS A prospective and descriptive study including 56 patients undergoing multiple orthopaedic procedures, who had received oral and written information and given informed consent. Literature on the topic was reviewed, a preliminary(More)
BACKGROUND AND OBJECTIVES This prospective, randomized, and multicentered study was undertaken to evaluate the success rate of coracoid infraclavicular nerve block performed with a nerve stimulator when either 1 or 3 motor responses were sought. METHODS Eighty patients who presented for elbow, forearm, or wrist surgery were randomly allocated to one of(More)
INTRODUCTION During continuous peripheral nerve blocks, infusion adjustments are essential for postoperative analgesia without side effects. Beside, physicians and nurse visits related to pump's settings and monitoring are time consuming and costly. We hypothesized that a remote control of pump's settings, by telemedicine transmission, adjusted to patients'(More)
