Suprascapular Nerve Block Efficacy for Shoulder Surgery

Peripheral nerve blocks are widely used for postsurgical analgesia. Interscalene nerve block provides a total brachial plexus motor and sensitive blockade while the suprascapular nerve block produces only a specific peripheral blockade. The interscalene nerve block is the most frequently used anesthesia technique and requires a longer learning curve. Complications related to this technique may be more severe and frequent in comparison to other regional anesthesia techniques. The suprascapular nerve block yields less adverse effects, discomfort and rebound effect as this technique does not completely block the upper limb motor function.
