Comparison of Rhomboid Intercostal-Subserratus Plane Block and Serratus Posterior Superior Intercostal Plane Block for Postoperative Analgesia and Dermatomal Spread After Modified Radical Mastectomy: A Randomized Double-Blind Trial
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This prospective randomized double-blind controlled trial aims to compare the postoperative analgesic efficacy and dermatomal spread of rhomboid intercostal-subserratus plane (RISS) block and serratus posterior superior intercostal plane (SPSIP) block in patients undergoing modified radical mastectomy. Postoperative pain scores, opioid consumption, rescue analgesic requirements, block-related complications, and quality of recovery outcomes will be evaluated.
