Analgesic Efficacy of Intertransverse Process Block Versus Erector Spinae Plane Block

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Intertransverse Process Block (ITP) and the Erector Spinae Plane (ESP) block in patients undergoing Robotic Colorectal Surgery. The primary outcome is the Visual Analog Scale (VAS) score within the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block-related and systemic side effects (hematoma, pneumothorax, local anesthetic systemic complications, vascular puncture, and infection), patient and surgeon satisfaction assessed using a Likert scale, and quality of recovery assessed using the QoR-15 questionnaire, and incedence of postoperative nausea and vomiting.
