Abstract
Objective
The objective was to identify factors associated with thrombocytopenia and to assess to what extent thrombocytopenia increases bleeding complications in liver transplant patients.
Design
Retrospective study.
Setting
Surgical intensive care unit in a university hospital.
Patients
One hundred and sixty-one patients admitted to the intensive care unit after liver transplantation.
Intervention
None.
Measurements and results
Incidence of thrombocytopenia was defined as a platelet count of <50×109/l for at least 3 consecutive days, associated events for thrombocytopenia or bleeding were identified by a Cox proportional hazard analysis, and blood product consumption was studied. Thrombocytopenia occurred in 104 patients (65%) with a mortality rate of 18% compared with 2% in nonthrombocytopenic patients (p=0.002). Independent associated events for thrombocytopenia were need of dialysis (hazard ratio [HR], 2.30; 95% confidence interval (95% CI), 1.10–4.80) and value of preoperative platelet count (HR, 1.06; 95% CI, 1.01–1.12 by 104 platelet decrease). The unique associated event identified for significant bleeding was sepsis (HR, 34.80; 95% CI, 1.47–153.40). Severe thrombocytopenia led to an excess of blood product consumption (red blood cells and platelets units) during ICU stay.
Conclusion
Thrombocytopenia of <50×109/l for 3 days is frequent after liver transplantation and as such is not an important contributor to bleeding. However, thrombocytopenia does reflect the severity of the postoperative course.
