Randomized Controlled TrialNerve stimulation under ultrasound guidance expedites onset of axillary brachial plexus block.
Axillary block is popular technique in upper extremity surgery. Nerve stimulation is used for location of nerves to provide effective blockade. The advent of ultrasound imaging technique in regional anaesthesia has increased the accuracy of needle placement and local anaesthetic deposition around the nerve. The aim of this study is to find out if the nerve stimulation technique with ultrasound guidance has advantages over sole nerve stimulation technique. The outcome measures studied were onset of sensory and motor block, procedure time, number of skin puncture, vascular puncture and paresthesia during nerve stimulation. ⋯ This study showed that the onset of sensory and motor block was faster with ultrasound assistance nerve stimulation. Complications can be decreased with the use of ultrasound in axillary block.
