Background: Post-reperfusion syndrome (PRS) is an important complication during liver transplantation.
Objective: We studied the occurrence and severity of PRS in patients who underwent orthotopic liver transplantation (OLT) to investigate how PRS was correlated to clinical variables and outcomes.
Methods: We retrospectively recorded intra- and peri-operative data for 184 adult patients who received cadaveric OLT during a 3-year period from 2005 to 2008. Patients were divided into two groups according to the severity of PRS: Group 1 (mild or no PRS) comprised 152 patients; and group 2 (significant PRS) consisted of 32 patients.
Results: There were no significant differences in demographic and pre-operative data between groups. Group 2 had more total blood loss than group 1 (p=0.036), especially after reperfusion (p=0.023). Group 2 required more packed red cell transfusions (p=0.005), more fresh frozen plasma (p=0.003) and more platelets (p=0.043) than group 1. Fibrinolysis was more frequent in group 2 (p=0.004). Hospital stay in group 2 was significantly longer than in group 1 (p=0.034), but the frequencies of other outcomes including infection, retransplantation, dialysis, rejection and extended donor criteria did not differ significantly between groups.
Conclusions: Bleeding, blood transfusion and fibrinolysis occurred more often in the group of severe PRS after reperfusion. Although postoperative complications like rejection, infection and the dialysis rate were not significantly different in the two groups, hospital stay was more prolonged in the group with severe PRS.
