A Comparative Evaluation of Three Techniques of Supraclavicular Brachial Plexus Block

Abstract :

Background:Brachial plexus block(BPB) is an excellent alternative to GA for upper limb surgery. US guided peripheral nerve blocks are rapidly gaining popularity by offering safety and accuracy.

Methods: The study included 105 patients who were randomly allocated into three groups of 35 patients each: GROUP CP(Conventional paresthesia technique), GROUP NS (Nerve stimulator guided) and GROUP US (Ultrasound guided). Results were statistically analyzed using one way anova test, chi–square test and Fisher exact test.

Results: Overall success rate was higher in GROUP US as compared to other two groups. BET was more inGROUP US. GROUP US had shorter onset time for sensory & motor blockade with prolonged duration of blockade. Conversion to GA either due to inadequate or failure of block was highest in GROUP CP. Patients overall satisfaction in GROUP US was significantly high compared to other two groups.

Conclusion: US guided supraclavicular BPB is a better nerve block technique as compared to other two techniques in terms of offering a safe block and optimal needle positioning.
