Use of recombinant activated factor VII in intractable bleeding during pediatric neurosurgical procedures.

OBJECTIVE

To report the use of recombinant activated factor VII (NovoSeven; Novo Nordisk A/S, Bagsvaerd, Denmark) in children undergoing major neurosurgical procedures and experiencing massive uncontrolled hemorrhagic shock.

DESIGN

Retrospective review of patients and analysis of clinical and biological effects of an intravenous administration of recombinant activated factor VII.

SETTING

Neurosurgical anesthesia and critical care unit of a pediatric university hospital.

PATIENTS/SUBJECTS: Four children, <12-kg body weight, experiencing life-threatening perioperative hemorrhage required conventional treatment (massive red blood cells, fresh frozen plasma, platelet transfusion, and surgical hemostatic maneuvers) that failed to obtain definite hemostasis.

INTERVENTIONS

Intravenous administration of recombinant activated factor VII (100 microg/kg).

RESULTS

Intravenous administration resulted in a significant decrease in blood loss within minutes (preventing further need of transfusion), normalization of biological hemostasis markers, and improved surgical hemostasis. No side effects of recombinant activated factor VII were noted, and all patients, except one, had a good recovery.

CONCLUSIONS

These four patients support the use of recombinant activated factor VII as a useful adjunct to control massive life-threatening bleeding during pediatric neurosurgical procedures when other means failed. However, the data are still limited in children, and more extensive research is needed to define the indications of recombinant activated factor VII in massive surgical hemorrhage in low-weight children.
