About

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

72 participants in 2 patient groups

subomohyoid suprascapular nerve

Experimental group

Description:

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.

Treatment:

Procedure: subomohyoid plane block

Interscalene brachial plexus

Active Comparator group

Description:

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

Treatment:

Procedure: Interscalene brachial plexus block
