Clinical Trial Study Protocol: A Prospective Blinded, Randomized, Controlled Clinical Trial Protocol to Assess the Efficacy of Ultrasound-Guided Transversus Abdominis Plane Block on Postoperative Analgesia and Recovery Quality in Laparoscopic Donor Hepatectomy.

Abstract

Liver transplantation is considered an effective treatment for end-stage liver disease. Laparoscopic donor hepatectomy (LDH) has become a new standard procedure. And it is important to minimize the pain of the donor. Good postoperative analgesia can reduce the occurrence of postoperative complications and promote the early recovery of the donor. Ultrasound-guided transversus abdominis plane (TAP) block can provide effective analgesia for liver donors and reduce postoperative opioid consumption. This study aims to use ultrasound-guided TAP block for LDH to improve postoperative analgesia for donors while reducing opioid consumption and improving patient rehabilitation quality. This study is a prospective blinded, randomized, controlled clinical trial with a concealed allocation of patients (living liver donors) scheduled to receive laparoscopic partial hepatectomy 1:1 to receive local infiltration anesthesia or TAP block. This study will recruit a total of 80 patients. The primary outcome is the dosage of opioids within 24hours after surgery. This trial has been approved by the Institutional Review Board of Beijing Friendship Hospital of China Capital University. This trial study protocol was approved on 8 May 2023. The trial will start recruiting patients after being registered on the Chinese Clinical Trial Registry. ChiCTR2300071694.
