Interscalene Block vs Serratus Posterior Superior Intercostal Plane Block
Recruiting now · Not applicable
Conditions studied: Shoulder Pain, Shoulder Disease
In brief
Postoperative pain is important following arthroscopic shoulder surgery. Postoperative effective pain treatment provides early mobilization and a shorter hospital stay. Ultrasound (US)-guided brachial plexus blocks, such as interscalene and supraclavicular block, are usually performed. Interscalen brachial plexus block (ISCB) is one of the most preferred techniques among these. Ultrasound (US) guided serratus posterior superior block (SPSPB) is a new interfacial plane block defined by Tulgar et al in 2023. It is based on injection on the serratus posterior superior muscle at the level of the 2nd or 3rd rib. This block provides analgesia in conditions such as interscapular pain, chronic myofascial pain syndromes, scapulocostal syndrome, and shoulder pain. The SPS muscle is located at the C7-T2 level. It attaches to the lateral edges of the second and fifth ribs. It is innervated by the lower cervical and upper intercostal nerves. With the SPS block, these nerves are blocked, and analgesia is provided. It has been reported that SPSIPB provides effective analgesia after shoulder surgery. The aim of this study is to compare the efficacy of the US-guided SPSIPB and ISCB for postoperative analgesia management after arthroscopic shoulder surgery.
