Rhomboid Intercostal Block Versus Retrolaminar Block for Postoperative Analgesia After Thoracoscopic Sympathectomy

Recruiting now · Not applicable

Conditions studied: Post Operative Pain

In brief

Background: Although thoracoscopic sympathectomy is made via small incisions, it is associated with severe postoperative pain. Both Rhomboid intercostal block (RIB) and Retrolaminar block (RLB) are recent techniques used for pain control after such procedures Objectives: To compare the effectiveness of RIB and RLB in providing postoperative analgesia after thoracoscopic sympathectomy in adult patients and their impact on the patient's outcomes. Patients and Methods: This prospective, randomized (1:1), double-blind clinical trial; will be carried out on 60 patients scheduled for elective thoracoscopic sympathectomy under general anesthesia at our hospital. Patients will be randomly allocated into two equal groups (30 patients each) and will receive: in group A; general anesthesia with intraoperative ipsilateral ultrasound-guided RIB, whereas in group B; general anesthesia with intraoperative ipsilateral ultrasound-guided RLB.
