Abstract

Background: There is increasing use of rFVIIa (eptagog alpha, Novoseven) in injured patients with critical bleeding. The role of rFVIIa is not defined in this group of patients. Registries provide an opportunity to review the patients, reported response and adverse events for rFVIIa. Aim: To determine the pattern of use, reported response and adverse events in patients receiving rFVIIa following injury using the Australian and New Zealand Haemostasis Registry (ANZHR). Methods: The ANZHR (commenced May 2005) collects data from 53 hospitals on all patients receiving rFVIIa in those hospitals. Results: Of 695 cases in the registry, 108 patients from 19 hospitals were submitted with a primary trauma diagnosis. Most (88) patients received one 90 μg/kg dose of rFVIIa. There was a significant reduction in the use of all blood products following rFVIIa (p < 0.001) and rFVIIa was thought to have decreased or stopped bleeding in 59% of cases. There was wide variation in the timing of rFVIIa use. There were two adverse events that were considered possibly linked and a total of three thromboembolic events. Following multivariate analysis, pH provided the best model of response to rFVIIa. Patients with a pH < 7.05 were significantly less likely to respond (OR = 0.3, 95% CI = 0.0-0.3). Only two patients would fit the criteria for the present prospective study of rFVIIA in trauma patients. Conclusion: The best approach to managing critical bleeding in trauma patients is not agreed. The role of rFVIIa will only be clarified if there is a standardised approach to fluid management and transfusion of blood products. The registry allows tracking of current practice, outcomes and adverse events and will complement present phase 2 and 3 trials.
