简要总结
The aim of our study was to compare the effects of interscalene block alone and the combination of interscalene block and superficial cervical block on cerebral oxygenation, carotid artery diameter, intraoperative hemodynamics, laboratory parameters, clinical course and postoperative pain in patients undergoing shoulder surgery.
详细描述
This study aimed to compare the effects of interscalene block alone and interscalene block combined with superficial cervical plexus block on cerebral oxygenation, carotid artery diameter, intraoperative hemodynamics, and postoperative pain in patients undergoing shoulder surgery.
Peripheral nerve blocks, particularly interscalene block, are commonly used in shoulder surgery due to their superior analgesic efficacy. Cerebral oxygenation was assessed using near-infrared spectroscopy (NIRS), a non-invasive method that reflects regional tissue oxygenation. The effects of both block techniques on bilateral cerebral oxygenation and carotid artery diameter were evaluated using NIRS and ultrasonography, respectively

结局指标
主要结局
The effect of regional anesthesia on cerebral oxygenation
时间窗: Before block; T1 After block; T2: 5. minute, T3: 10. minute, T4: 15 minute, T5: 20 minute / In the beach chair position; T6: 1. minute, T7: 10. minute, T8: 30. minute, T9: 60. minute, T10: surgical end, Postoperative supine; T11: 5. minute
We plan to investigate the effect of interscalene block or a combination of interscalene and superficial cervical block on oxygenation of both hemispheres of the brain using a NIRS probe.
次要结局
- The effect of regional anesthesia on carotid artery diameter(Before block; T1 After block; T2: 5. minute, T3: 10. minute, T4: 15 minute, T5: 20 minute / In the beach chair position; T6: 1. minute, T7: 10. minute, T8: 30. minute, T9: 60. minute, T10: surgical end, Postoperative supine; T11: 5. minute)
- The effect of the two-block method on the duration of first postoperative analgesia requirement and opioid consumption(From the end of surgery until the first request for postoperative analgesia and the amount of opioid comsumption, assessed up to 24 hours postoperatively)
