AIM 1: Determine the safety profile of direct peritoneal resuscitation on liver transplant recipients at risk of return to the operating room and ICU admission. Hypothesis: Liver transplant recipients that receive DPR will have comparable complication rates to historic controls of liver transplant recipients with similar demographics. AIM 2: Identify if direct peritoneal resuscitation demonstrates a trend towards a reduced rate of return to the operating room compared to historic controls. Hypothesis: DPR will demonstrate a trend of a reduce rate of return to the operating room of liver transplant patients after index operation compared to historic controls. AIM 3: Identify if direct peritoneal resuscitation reduces the rate of early allograft dysfunction and other organ failure following liver transplantation with interval improvement in post-operative fibrinolysis activity. Hypothesis: DPR will reduce the rate of EAD of liver transplant patients compared to historic controls and is associated with increased fibrinolysis in the post-operative period.

This study is being conducted to assess the safety of Direct Peritoneal Resuscitation (DPR) in high-risk liver transplant patients. The investigators want to also identify if this method of recovery after large surgery has the same benefits in liver transplant patients as have been appreciated in other surgical patients. An elevated body mass index (BMI) increases the risk of 1) needing intensive care unit (ICU) admission after surgery, 2) slow function of the new liver [technically termed Early Allograft Dysfunction (EAD)] and 3) need for more than one operation. The study team also aims to identify if DPR can reduce these risks and not cause other unexpected complications following surgery. DPR involves the infusion of a solution into the abdomen and has been shown to reduce edema and improve blood flow in organs. The solution used in this study is a commercially available peritoneal dialysate, a dextrose containing solution that is infused into the abdominal cavity and is routinely used in patients with end-stage renal disease requiring dialysis.
