Liver Transplantation, Surgical Site Infection
Conditions
Brief summary
This study will be to prospectively determine differences in Surgical Site Infection (SSI) if a prolonged course of post-operative antibiotics are used following liver transplantation.
Detailed description
This study will be to prospectively determine differences in SSI if a prolonged course of post-operative antibiotics are used following liver transplantation. All adult patients, admitted to the University of Virginia (UVA) Medical Center for first-time liver transplantation will be randomized to the standard of care of peri-operative antibiotics or extended course of three total days. Patients will be evaluated primarily for the presence of post-operative surgical site infections but also for fever, elevated white blood counts, secondary infections (urinary tract, pneumonia, and blood stream), length of hospital stay, graft loss, and mortality for 30 days after liver transplant.
Interventions
peri-operative antibiotic regimen only
extended three-day course of antibiotics
orthotopic liver transplantation

Eligibility
Inclusion criteria
* All patients ≥ 18 years of age. * Eligible for liver transplantation by UVA standard protocol. * First-time transplantation. * No active infections - requiring antibiotics - excluding antifungals.
Exclusion criteria
* All patients \< 18 years of age. * Previous liver transplantation. * Active infections - requiring antibiotics. * Allergy to all standard peri-operative antibiotics (piperacillin/tazobactam or UVA standard alternatives for Penicillin allergic patients: ciprofloxacin and vancomycin).

|---|---|
| Standard Peri-operative Antibiotic Regimen The standard of care at the University of Virginia Medical Center for liver transplantation patients is a 3.375 gram dose of piperacillin / tazobactam (Zosyn®) at the time of induction of anesthesia, though this dose may be adjusted for renal insufficiency. This dose is repeated during the operation every six hours.
standard: peri-operative antibiotic regimen only
steroids: 500mg methylprednisolone intravenously
liver transplant: orthotopic liver transplantation | 52 |
| Extended Three-day Course of Antibiotics For those patients randomized to the study group, antibiotics will be started as per the usual intra-operative dosing regimen, then continued to provide coverage for 72 hours.
This is typically provided as additional doses of 3.375 grams of piperacillin / tazobactam (Zosyn®) every 8 hours for 3 total days (giving a total of 72 hours of antibiotic coverage), though this may be altered based on kidney function.
extended: extended three-day course of antibiotics
steroids: 500mg methylprednisolone intravenously
liver transplant: orthotopic liver transplantation | 50 |
| Total | 102 |
