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

Interventions

Type	Name	Description
PROCEDURE	interscalene block group	The ISB group scanning was done by linear ultrasound probe just below the level of the cricoid cartilage medial to the sternocleidomastoid muscle; the skin was disinfected, and the transducer was positioned in the transverse plane to identify the carotid artery. Once the artery was identified, the transducer was moved slightly laterally across the neck to identify the scalene muscles and the brachial plexus that is present between the anterior and middle scalene muscles. 3 ml lidocaine 1% was injected at puncture site The needle was then inserted in-plane toward the brachial plexus, in a lateral-to-medial direction. After a careful aspiration, 20 ml of bupivacaine 0.25% was injected.
PROCEDURE	Suprascapular nerve block group	After cleaning the skin with an antiseptic solution, an ultrasound probe was put in sagittal orientation at the superior medial border of the scapula to identify the pleura and then moved laterally; when it was parallel to the spine of the scapula, the transducer was moved cephalad and the suprascapular fossa was identified, and then the transducer was moved lateral to locate the suprascapular notch. The suprascapular nerve was a round hyperechoic structure beneath the transverse scapular ligament in the scapular notch. 3 ml lidocaine 1% was injected at puncture site then the needle was inserted along the longitudinal axis of the ultrasound beam, and 10 ml of bupivacaine 0.25% was injected.
