What this trial studies
This clinical trial aims to compare the effectiveness of two regional analgesia techniques, Rhomboid Intercostal Block (RIB) and Retrolaminar Block (RLB), for managing postoperative pain in adult patients undergoing thoracoscopic sympathectomy. The study will involve 60 patients who will be randomly assigned to receive either RIB or RLB during their procedure under general anesthesia. The primary focus is to evaluate the impact of these techniques on pain control and overall patient outcomes following surgery.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing thoracoscopic sympathectomy.
How similar studies have gone: While the specific techniques of RIB and RLB are relatively novel, similar regional analgesia approaches have shown promise in managing postoperative pain in other surgical contexts.
