Spinal Anesthesia for Enhanced Recovery After Liver Surgery
This project proposes to compare epidural versus spinal anesthesia in patients having liver resection surgery. The investigators hypothesize that spinal anesthesia will result in improved blood pressure control postoperatively and reduce the amount of intravenous fluids required after surgery. Spinal anesthesia is expected to provide the same pain control benefits as epidurals, with faster recovery of function. Spinal anesthesia may be a simple and effective way to improve and enhance the recovery in the increasing number of patients requiring liver resection.
• Male or female, Adults aged ≥ 18 years (there will be no upper age restriction);
• American Society of Anesthesiologists Physical Status classification (ASA-PS) of I to III;
• Undergoing subcostal or midline laparotomy for elective liver resection surgery under general anesthesia; if the planned procedure is a combined operation (i.e., concomitant extrahepatic surgery) , the associated procedure should not add more than one hour to the surgical time of the primary hepatic resection procedure alone;

• Provision of signed and dated informed consent form
• Body mass index (BMI) between 17 and 40 kg·m-², inclusive;
• Negative result on serum pregnancy test at Screening and negative urine pregnancy test at Baseline (for women of childbearing potential, defined as those who have not undergone a hysterectomy or been postmenopausal for at least 12 consecutive months); and not currently breastfeeding, or planning to do so within 7 d following surgery;
• Stated willingness and ability to comply with all study and/or follow-up evaluations and communicate clearly with the Investigator and staff; and
