Elderly patients undergoing minimally invasive gastrointestinal tumor surgery face complex postoperative pain management due to age-related physiological decline and surgical particularities, where traditional opioids are prone to adverse effects. Our study investigates the clinical analgesic efficacy of ultrasound-guided transversus abdominis plane block (TAPB) in these patients, focusing on analgesic quality, delirium incidence, opioid consumption, and postoperative recovery indicators. This evaluation aims to assess its clinical value and safety while providing evidence-based insights for optimizing perioperative analgesia protocols.
