Introduction: Some groups have reported early extubation post-liver transplantation in patients with previously defined criteria, in an attempt to shorten the ICU stay and decrease costs. We review our experience with trends in mechanical ventilation and resource utilization.
Methods: We retrospectively reviewed the length of mechanical ventilation, ICU stay, hospital stay, transfusions, and costs of liver transplants performed since the program's inception in 1993 and 2002 including 82 OLT in 71 patients. We also report our experience with immediate postoperative extubation, which we have done from October to December of 2002. We compare different periods: the early days (1993 to 1997), namely, fewer than 10 OLT per year, with the subsequent years assessed individually.
Results: There has been a progressive decrease over time in the length of mechanical ventilation, ICU stay, hospital stay, and costs. Since the program's inception actuarial adult patient 1- and 5-year survival rates were 88.7% and 78%, respectively. The 1-year survival rate increased to 97% during the period of 2000 to 2002 (n = 30). From October to the present, we extubated four of seven adult patients who met criteria with none of them requiring reintubation.
Conclusions: We demonstrate improved results, decreased length of mechanical ventilation, ICU, and hospital stay, and costs. The immediate postoperative extubation may be feasible for patients who meet previously defined criteria.
