Brief summary

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

Interventions

PROCEDUREsubomohyoid 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

PROCEDUREInterscalene 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.
