Randomized, controlled trial comparing respiratory and analgesic effects of interscalene block, anterior suprascapular, and posterior suprascapular nerve block for arthroscopic shoulder surgeries.
Abstract
Interscalene brachial plexus block (ISB) provides excellent analgesia for arthroscopic shoulder surgeries but is associated with adverse effects including hemidiaphragmatic paresis from phrenic nerve blockade. The primary aim is to compare the respiratory effects, forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1), of suprascapular nerve block (SSB) with ISB.
