Comparison of Supraclavicular Brachial Plexus Block Guided by PNS, USG and Combined Method

This randomized comparative study evaluated supraclavicular brachial plexus block using three techniques in patients undergoing elbow and below-elbow surgeries. A total of 75 patients were included and allocated into three groups: Group A received a peripheral nerve stimulator (PNS)-guided block, Group B received an ultrasound-guided (USG) block, and Group C received a combined USG and PNS-guided block. The three techniques were compared with respect to ease of administration, success rate and quality of block, including duration of analgesia.

Inclusion Criteria: 1. Patients scheduled for elective elbow and below-elbow surgeries under supraclavicular brachial plexus block at Pravara Rural Hospital, Loni. 2\. Patients of either sex. 3. Patients aged between 20-60 years. 4. Patients with informed written consent. 5. ASA I and II. \- Exclusion Criteria: 1. Infection at the site of block. 2. Neuropathy (diabetic neuropathy). 3. Allergy to local anaesthetics. 4. Neurological deficits. 5. Uncontrolled diabetes mellitus. 6. Old pulmonary pathology. -
