Abstract


Background and objectives: The aim of the study is to compare the efficacy and execution time of supraclavicular block of brachial plexus using ultrasound guidance and nerve stimulation compared with a supraclavicular block that used anatomical landmarks and nerve stimulation

Methods: A prospective randomized study conducted on 40 ASA I andII patients undergoing upper limb surgeries undersupraclavicular brachial plexus block. The study was started after receiving institutional ethical committee approval and informed written consent. They were randomly divided into two groups.

US- 20ml of  0.5% bupivacaine+20 ml of 2% lignocaine with 1 in 2,00,000 epinephrine.

NS-20ml of  0.5% bupivacaine+ 20 ml of 2% lignocaine with 1 in 2,00,000 epinephrine

Results: Demographic parameters were comparable in both groups. Onset of sensory and motor blockade in US group were shorter than in NS group and the difference was statistically significant . The number of needle attempts was lesser in group US (Mean1.2) compared to the group NS (Mean2.2).

Conclusions: Ultrasound with nerve stimulation allowed statistical and clinically significant decrease in procedure time, quicker onset and provided better success rate than a nerve stimulator guided method alone.
