Usually NOT eligible if any of the following apply:

• Exclusion Criteria:
• Emergency surgery;
• Age \< 18 years;
• Planned laparoscopic hepatic resection;
• Planned laparotomy incision other than (right) subcostal, midline, or extended midline;
• Patients with obvious non-resectable disease prior to signing informed consent;
• Liver transplant recipient or previous hepatic resection or living-donor hepatectomy surgery;
• Major surgery (open abdominal and/or thoracic) under general anesthesia ≤ 30 d preoperatively;
• Contraindications to neuraxial (spinal or epidural) anesthesia: (a) anticipated difficult intubation; (b) coagulation or hemostatic abnormalities within 30 d of surgery (defined as thrombocytopenia \[platelet count \< 100 × 10⁹ L-¹\]; INR \> 1.4; or activated partial thromboplastin time \[aPTT\] \> 40 s); (c) bleeding diathesis; (d) ongoing use (≤ 7 d before surgery) or planned perioperative use of antiplatelet agents (apart from acetylsalicylic acid 81 mg) or anticoagulants (excluding deep-vein thrombosis prophylaxis); (e) recent (≤ 30 d preoperatively) systemic infection or current (≤ 48 h) fever (≥ 38.4 °C), or evidence of infection (including superficial cutaneous infection in the thoracic and/or lumbar regions); (f) history of neurologic disorder affecting the spinal cord or the hemithorax or below; or impaired bladder/bowel function; (g) acute or subacute (≤ 90 d preoperatively) intracranial hemorrhage; or (h) technical contraindications to epidural placement: (i) local skin or soft tissue infection at proposed site for thoracic epidural insertion; (ii) previous cervicothoracic, thoracic, or thoracolumbar spinal surgery; (iii) history of spinal tumor, fracture or infection; or (iv) recent (≤ 14 d preoperatively) epidural corticosteroid injection;
• Significant cardiac arrhythmias (including pacemaker-dependence) or clinically significant cardiovascular disease (New York Heart Association \[NYHA\] functional classification III-IV);
• Volume overload (hyperhydration), particularly in cases of pulmonary edema or acute decompensated congestive heart failure (CHF);
• Acute kidney injury (AKI) and/or chronic kidney disease (CKD) based on the 2012 Kidney Disease Improving Global Outcomes (KDIGO) AKI (excluding the oliguria criterion) and CKD guideline definitions: AKI: increase in serum creatinine (SCr) (≥ 26.5 μmol·L-¹ within 48 h or ≥ 1.5× baseline within 7 d); CKD: abnormalities of kidney structure or function, present for \> 3 mo, defined as either of the following present for \> 3 mo: (1) ≥ 1 marker(s) of kidney damage: (a) albuminuria (24-h albumin-creatinine ratio \[ACR\] ≥ 30 mg·g-¹ \[≥ 3 mg·mmol-¹\]), (b) urine sediment abnormalities, (c) electrolyte and other abnormalities due to tubular disorders, (d) abnormalities detected by histology, (e) structural abnormalities detected by imaging, (f) history of kidney transplantation; and/or decreased glomerular filtration rate (GFR \< 60 mL-¹·min-¹·1.73 m-², estimated using the 2009 CKD-EPI creatinine equation \[eGFR\_creat\]);
