Evaluación del riesgo de fenómenos trombóticos tras el uso de factor vii activado

Abstract

IntroductionThe objective of this study was to analyze the incidence of thrombotic complications related to recombinant human factor viia (rFVIIa) therapy for severe postoperative bleeding in cardiac surgery. Material and methodsA retrospective matched case-control study was conducted over two years, including 72 children admitted to intensive care unit and treated with rFVIIa because of a severe bleeding during or after cardiac surgery. A control group of 63 patients was chosen, who were statistically comparable in sex, weight, diagnosis, surgical risk according RASCH-1 score, and surgical characteristics, was chosen. ResultsThere were no significant differences between cases and controls either in the rate of thrombosis (20% vs 28%, P=.540), or in the mortality rate (16% vs 9.5%, P=.208). ConclusionsIn our study, the rFVIIa therapy was shown to be useful in controlling severe operative bleeding in pediatric cardiac surgery, but does not seem to increase the risk of thrombotic complications or mortality rate in the postoperative pe riod.
