About

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.

Full 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
