简要总结
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.
详细描述
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

结局指标
主要结局
visual analogue score
时间窗: 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
次要结局
- Patient satisfaction(24 hours postoperatively)
