Median ulnar nerve selective blockage versus brachial plexus blockage in carpal tunnel release surgery

Abstract

Aim: This study aimed to evaluate the feasibility of median ulnar nerve selective blockage vs. brachial plexus blockage in dayprocedures such as carpal tunnel release surgery. We hypothesized that selective median and ulnar blockage is a feasible classicaxillary approach.Material and Methods: This randomized, controlled, double-blind, single-center study included 60 patients. Patients were randomlyallocated to two groups; namely, the plexus blockage group (control) and selective group. Patients in the plexus blockage group wereadministered with 15 ml of local anesthetic for axillary plexus, and in the selective group, 2.5 ml of local anesthetic was applied underUSG guidance. We evaluated of full sensory and motor block.Results: The onset of motor block time was observed to be longer and recovery time was shorter in the selective group than in theplexus blockage group (P
