Official title
Ultrasound-guided Rhomboid Intercostal Block Versus Retrolaminar Block for Postoperative Analgesia After Thoracoscopic Sympathectomy: A Randomized Clinical Trial
Overview
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.
Interventions
- Procedure Rhomboid Intercostal Block (RIB)
Intraoperative Ipsilateral Ultrasound-guided RIB - Procedure Retrolaminar Block (RLB)
Intraoperative Ipsilateral Ultrasound-guided RLB
Primary outcome measures
- Mean and Standard deviation of time to the first request of postoperative rescue analgesic (minutes) (mean±SD) [Time frame: 24 hours after the end of surgery]
Secondary outcome measures (2)
- Mean and Standard deviation of Numeric Pain Rating Scale (NPRS) score (mean±SD) [Time frame: 24 hours after the end of surgery]
- Mean and Standard deviation of the total dose of the rescue analgesic consumed (milligrams) (mean±SD) [Time frame: 24 hours after the end of surgery]
