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.

Conditions

Shoulder Surgery

Keywords

Anterior Suprascapular Nerve Block; Suprascapular Nerve Block

Outcome Measures

Primary Outcomes (1)

• visual analogue score

  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

  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

Secondary Outcomes (1)

• Patient satisfaction

  24 hours postoperatively

Study Arms (2)

interscalene block group

EXPERIMENTAL

patients received an ultrasound guided interscalene approach of brachial plexus plane block

Procedure: interscalene block group

suprascapular nerve block group

EXPERIMENTAL

patients received ultrasound guided suprascapular nerve block.

Procedure: Suprascapular nerve block group

Interventions

interscalene block group PROCEDURE

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.

Also known as: Group ISB

interscalene block group

Suprascapular nerve block group PROCEDURE

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.

Also known as: group SSNB
