简要总结
This randomized clinical study aims to compare the effects of two different ultrasound-guided infraclavicular brachial plexus block techniques-costoclavicular and lateral sagittal approaches-in patients undergoing forearm, wrist, or hand surgery.
The primary objective of the study is to evaluate and compare the incidence of hemidiaphragmatic dysfunction associated with these two block techniques. Secondary outcomes include sensory and motor block characteristics, postoperative pain scores, analgesic requirements, and potential block-related complications.
Eligible adult patients scheduled for elective forearm or hand surgery are randomly assigned to receive either a costoclavicular or a lateral sagittal infraclavicular nerve block using bupivacaine under ultrasound guidance. Standard general anesthesia and postoperative analgesia protocols are applied.
The results of this study are expected to provide evidence on the relative safety and efficacy of these two infraclavicular block approaches, particularly regarding diaphragmatic function, and to help guide anesthesiologists in selecting the most appropriate regional anesthesia technique for upper extremity surgery.

结局指标
主要结局
Diaphragmatic excursion
时间窗: Baseline(pre-block) and 30 minutes after block performance.
Diaphragmatic excursion measured by ultrasound during normal and deep breathing to asses the effect of costoclavicular and lateral sagittal infraclavicular block techniques.
次要结局
- Sensory and motor block onset time(Within the first 30 minutes after block performance.)
- Time to first postoperative analgesic requirement(Within the first 24 hours postoperatively.)
