Association of Preoperative Plateletcrit and Other Inflammatory Indices with Postoperative Pain Severity and Opioid Consumption in Morbidly Obese Patients Receiving Transversus Abdominis Plane Block: A Retrospective Observational Study

Background

Bariatric surgery induces a systemic inflammatory response to surgical stress that may influence postoperative pain and analgesic requirements, and CBC-derived inflammatory indices can reflect preoperative and postoperative immunometabolic dynamics related to this response. This retrospective observational search evaluated whether inflammatory indices derived from routine complete blood counts are associated with postoperative pain and opioid consumption after ultrasound-guided transversus abdominis plane (TAP) block in patients with morbid obesity.
