ObjectiveTo analyze the incidence of bacterial lung infection after orthotopic liver transplantation and its risk factors.
MethodsNinety-six patients with end-stage liver disease who underwent liver transplantation from Jan. 2010 to Jun. 2012 in our hospital were retrospectively analyzed. The relationship of preoperative, intraoperative, and postoperative variables with early postoperative bacterial lung infection was explored by multivariate non-conditional logistic regression.
ResultsTwenty-nine cases of 96 cases after liver transplantation occurred early bacterial lung infection, and the infection rate was 30.21%(29/96), in which G-aerobic bacteria infection accounted for 65.52%(19/29), and G+ aerobic bacteria accounted for 34.48%(10/29). Preoperative model for end-stage liver disease score(OR=2.165, P=0.001), intraoperative blood transfusion(OR=1.952, P=0.003), average of plasma creatinine during 3 days after operation(OR=1.913, P=0.001), liquid negative balance time during 3 days after operation(OR=0.916, P=0.023), and postoperative hospital stay(OR=1.923, P=0.003) were all associated with early postoperative bacterial lung infection.
ConclusionsRetrograde reperfusion in orthotopic liver transplantation patients are susceptible to bacterial lung infections. Improving basic status before operation, controlling volume of intraoperative blood transfusion, the volume of transfusion, and postoperative hospital stay, and improving renal function can reduce incidence of early postoperative bacterial lung infection.
