Summary
The aim of this study is to evaluate the effectiveness of low versus high volumes of local anesthetic in ultrasound-guided combined supraclavicular block (SCB) and interscalene block (ISB) for upper limb surgery. This randomized, controlled trial will assess the analgesic effectiveness of low-volume local anesthetic in these blocks. We hypothesize that a low volume will provide similar analgesic effects to a high volume, with fewer complications. The study will involve 40 adult ASA I and ASA II patients undergoing upper limb surgery, divided into two groups: Group A (low volume) and Group B (high volume). The primary outcome will compare intraoperative and postoperative analgesic effects of different volumes. The secondary outcome will evaluate complications related to local anesthetics (toxicity) and injection techniques (e.g., phrenic nerve palsy, pneumothorax, hematoma).
