Continuous Infraclavicular Blocks: Neurostimulation Versus Ultrasound

London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's210 enrolled

Overview

The purpose of this study is to determine whether ultrasound guidance or nerve stimulation is the best option for placing continuous peripheral nerve block catheters for upper limb surgery.

In a multidisciplinary, observer blinded, prospective, single center, randomized study, success rate of US guided versus neurostimulation guided catheter placement for continuous infraclavicular block in patients scheduled for upper limb surgery will be studied. Block effectiveness, time taken, discharge from recovery, postoperative pain and disability and patient acceptance will be studied in 210 patients.
