Activated recombinant factor VII for refractory bleeding during extracorporeal membrane oxygenation.

ABSTRACT

OBJECTIVE: To determine the frequency of adverse events with the use of activated recombinant factor VII during extracorporeal membrane oxygenation support and to quantify the effect on bleeding parameters. DESIGN: Retrospective case series from January 1999 to August 2006. SETTING: Pediatric intensive care unit at a tertiary academic children's hospital. PATIENTS Seventeen patients received a total of 26 doses of activated recombinant factor VII while supported on extracorporeal membrane oxygenation or within 3 hrs of initiation of extracorporeal membrane oxygenation support from February 2003 to August 2006, and 23 historical controls from January 1999 to December 2002 with bleeding complications reported to the Extracorporeal Life Support Organization database while supported on extracorporeal membrane oxygenation before the use of activated recombinant factor VII. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: No significant difference in the rate of thromboembolic complications, extracorporeal membrane oxygenation circuit failures, or mortality was found between the patients and historical controls. No trend toward increased survival was found, and a significant number of circuit complications was seen in both groups. In patients treated with activated recombinant factor VII, a significant reduction in chest tube output and blood product transfusion rates was seen within 5 hrs of activated recombinant factor VII administration. CONCLUSION: Activated recombinant factor VII administration during extracorporeal membrane oxygenation support was associated with a decrease in bleeding severity (indicated by chest tube output and blood product transfusion rates) and was not associated with an increased rate of thromboembolic complications.
