COMPARISON OF ULTRASOUND GUIDED TECHNIQUE WITH CONVENTIONAL LANDMARK TECHNIQUE FOR SUPRACLAVICULAR BRACHIAL PLEXUS NERVE BLOCK IN PATIENTS UNDERGOING UPPER LIMB SURGERIES
Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 7
Abstract
Background: supraclavicular block offers dense anaesthesia of the brachial plexus of surgical procedures at or distal to the elbow. Landmark technique has been traditionally used. But blind technique often requires multiple trial and error needle attempts, resulting in long procedure time, procedure related pain, discomfort and lethal complications. Ultrasound is a new technique with short procedure time, less pain, discomfort and complications. Objectives: The main objectives of the study was to compare both the techniques in terms of time taken for the procedure, onset and duration of sensory and motor blockade, effectiveness of the block. Methods: We included 60 ASA I or ASA II patients, aged from 17 to 60 years who underwent elective upper limb surgeries under supraclavicular block. Patients were divided into two groups. In one group (Group C n=30) conventional subclavian perivascular technique was used while in other group (Group US n=30), supraclavicular nerve block was performed under ultrasound guidance. Block was performed with 15 ml of 0.5% bupivacaine and 15 ml of 2% lignocaine with adrenaline 1:2,00,000 in both the groups. Results: when compared with conventional technique, the onset of sensory and motor blockade is found to be earlier, the duration of sensory and motor blockade is found to be prolonged, analgesic requirement is reduced and overall effectiveness was better with ultrasound guided supraclavicular block. Time taken for the block performed by ultrasound was little longer than the conventional subclavian perivascular technique. Conclusion: Ultrasound guided supraclavicular block has a rapid onset of both sensory and motor blockade, prolonged duration of blockade, reduced analgesic requirements with increased success rate and fewer complications.
