Ultrasound Guided Suprascapular Nerve Block Versus ISB Block in Arthroscopic Shoulder Surgery

Not Applicable

Completed

• Conditions: Shoulder Surgery
• Interventions: Procedure: interscalene block group; Procedure: Suprascapular nerve block group

• Registration Number: NCT06396455
• Lead Sponsor: Benha University

Brief Summary

Diaphragmatic dysfunction can be detected as a decrease in forced vital capacity (FVC) and forced expiratory volume at 1 s (FEV1) on spirometry or as lower diaphragmatic excursion (DE) on US, the latter having become the gold standard in thoracic assessment.

Detailed Description

Severe intraoperative and postoperative pain associated with arthroscopic shoulder surgery has high incidence reaching up to 45%; it is often significant enough to interfere with initial recovery and rehabilitation.

Shoulder arthroscopy is becoming more common, representing the second most common Orthopedic surgery after knee arthroscopy . Interscalene brachial plexus block (ISB) is the gold standard analgesic technique for shoulder surgeries with success rates of 87% to 100%, but it also blocks the phrenic nerve (C3-C5).

Suprascapular nerve block via the anterior approach (SSB-A) is performed distally at the trunk/division level of the brachial plexus, thereby potentially sparing the phrenic nerve and minimising many adverse effects of ISB

Arm && Interventions

Group	Intervention	Description
interscalene block group	interscalene block group	patients received an ultrasound guided interscalene approach of brachial plexus plane block
suprascapular nerve block group	Suprascapular nerve block group	patients received ultrasound guided suprascapular nerve block.

Primary Outcome Measures

Name	Time	Method
visual analogue score	Postoperative pain was assessed using VAS at Postoperative care unit, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, and 24hours after block administration postoperatively	The visual analogue score (VAS) was used (0 indicating no pain and 10 indicating worst unbearable pain) at rest and upon flexion for assessment of pain intensity upon arrival to the PACU

Secondary Outcome Measures

Name	Time	Method
Patient satisfaction	24 hours postoperatively	Patient satisfaction was evaluated using 5-point Likert scale) (1=extremely dissatisfied; 5=extremely satisfied)
