A study on efficacy of brachial plexus block through axillary approach with regards to onset time and duration of blockade by using lignocaine chloride: A case control clinical study

Abstract

Brachial plexus block via the axillary approach is good alternative in patients with limited arm mobility. The purpose of our study was to observe the block characteristics for the axillary approach for brachial plexus block in patients undergoing forearm and hand surgeries. After obtaining institutional approval and written informed consent, 50 patients of American Society of Anaesthesiologists grade I or II scheduled for forearm and hand surgeries were included in the study. Brachial plexus block was performed via the axillary approach. Sensory block in the distribution of individual nerves supplying the arm, motor block and duration of sensory block were recorded. Successful block was achieved in 90% of the patients in axillary approach. The axillary approach because of its easily identifiable landmarks, a comfortable patient position during the block procedure and the ability to block a larger spectrum of nerves should thus be considered as an effective alternative to the other approach.
