Analgesic Efficacy of Ultrasound-Guided Rhomboid Intercostal Sub Serratus Plane Block Versus Serratus Anterior Plane Block With General Anesthesia in Thoracotomy

What this Trial Is About

This research aims to compare the pain relief effects of two ultrasound-guided nerve block techniques, the rhomboid intercostal sub-serratus plane (RISS) block and the serratus anterior plane block (SAPB), in patients undergoing thoracotomy surgery. Thoracotomy is known for causing severe postoperative pain that affects recovery and breathing. The study focuses on evaluating which of these regional anesthesia methods provides better pain control and reduces opioid use after surgery. Participants will receive either the RISS block or the SAPB under ultrasound guidance during their thoracotomy procedure. The RISS block involves injecting local anesthetic between the rhomboid major muscle and the intercostal muscles, while the SAPB targets the lateral cutaneous branches of the thoracic intercostal nerves near the serratus anterior muscle. Both techniques use bupivacaine as the anesthetic, and the procedures are performed with a high-frequency linear ultrasound probe to ensure accurate placement. Throughout the study, participants will be closely monitored for opioid consumption in the 24 hours after surgery, as well as pain levels at rest and during coughing at multiple time points up to 24 hours postoperatively. Additional measurements include heart rate, blood pressure, oxygen levels, hospital stay length, patient satisfaction, and potential side effects like nausea or local anesthetic toxicity. The total study duration covers surgery and 24 hours of postoperative observation, with detailed data collected to assess the effectiveness and safety of each block method.
