Sub Omohyoid Suprascapular Nerve Block Versus Interscalene Nerve Block

Sub Omohyoid Suprascapular Nerve Block Versus Interscalene Nerve Block for Postoperative Shoulder Surgery Pain: Randomized Comparative Study.

Shoulder surgery can be very painful surgery after which the use of opioids is often required. The well-known side-effects of opioids (e.g. respiratory depression, somnolence, nausea, vomiting, and pruritus) limit their use in so called 'fast track' surgery and anaesthesia programmes.

the study aimed to compare the effect of sub omohyoid suprascapular nerve block versus interscalene nerve block in preventing postoperative pain and decreasing analgesic consumption in patients scheduled for shoulder surgery

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Interscalene brachial plexus; ultrasound-guided interscalene block involves imaging the C5 and C6 roots at approximately the level of the cricoid cartilage, just distal to where they emerge from behind their respective transverse processes and where they lie in the groove between the anterior and middle scalene muscles	Procedure: Interscalene brachial plexus block; The block needle is usually advanced in plane in a lateral-to-medial direction through the middle scalene muscle to contact the nerve roots and inject local anesthetic around them.
Experimental: subomohyoid suprascapular nerve; superficial probe of ultrasound was placed in the transverse plane to visualize the superior trunk in the short axis. The suprascapular nerve was identified as it branched off from the superior trunk and traced until it coursed beneath the inferior belly of the omohyoid muscle.	Procedure: subomohyoid plane block; The block needle was inserted in line with the probe in a lateral-to-medial orientation toward the suprascapular nerve. Local anesthetic solution was then injected after negative aspiration for blood to achieve circumferential spread around the neurovascular bundle
