Abstract :

A prospective randomized double blind study was undertaken to compare sensory and motor blockade with single injection method and double injection method of axillary plexus with 20 ml of 1.5% Lignocaine for elective surgeries of forearm & hand. METHODS Sixty patients of ASA class I of age 18–60yrs posted for elective surgeries of forearm and hand were randomly divided into two groups. Group S (single injection method) and Group D (double injection method). Each group consisting of 30 patients to receive 20 ml of 1.5% Lignocaine in single injection method and 20ml of 1.5% Lignocaine in double injection method. . Statistical analysis:the data was analysed using two tailed tests for differences between means of two samples(Z test) and in needed situation using x2 test.significant level for rejecting null hypothesis was taken p<0.05 RESULTS There was faster onset of sensory and motor block in patients of Group D compared to patients of Group S. In group D 96% of Patients had effective sensory neural blockade compared to 86.6% in patients of Group S. . In Group S only 4 (13.3%) patients needed supplementation and 86.6% of block was effective. In Group D all patients had complete blockade and needed no supplementation. The duration of analgesia was prolonged in patients of Group D. Inspite of complete motor block of 46% and 86% in patients of Group S and Group D respectively, surgical procedures were conducted without any issues on to the patients. The duration of motor block was 4 hours in patients of Group D where as 2 hours in patients of Group S.
