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.
