Intravenous patient-controlled fentanyl with and without transversus abdominis plane block in cirrhotic patients post liver resection

Background Coagulation changes can complicate liver resection, particularly in patients with cirrhosis. The aim of this prospective hospital-based comparative study was to compare the postoperative analgesic efficacy of intravenous fentanyl patient-controlled analgesia (IVPCA) with and without transversus abdominis plane (TAP) block.
