Summary

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.

Conditions

  • Regional Anaesthesia
  • Transversus Abdominis Plane Block (TAP Block)
  • Pain, Postoperative

Interventions

PROCEDURE

Transversus Abdominis Plane Block, TAPB

The procedure was performed by anesthesiologists with extensive expertise in nerve blockade techniques. For upper abdominal surgical incisions, a subcostal approach transversus abdominis plane block (TAPB) was implemented under ultrasound guidance to identify the transversus abdominis plane. A total of 20 mL of 0.33% ropivacaine hydrochloride injection (Naropin®) was incrementally administered, followed by contralateral application using identical techniques, with ultrasonographic confirmation of fusiform drug distribution within the transversus abdominis plane to achieve upper abdominal incision analgesia. For lower abdominal incisions, a lateral approach was employed, with the same dosage of local anesthetic injected at the target site and bilateral blocks performed after confirming fluid dispersion patterns under real-time ultrasound visualization.
