[Excessive blood loss after abdominal hysterectomy -- use of recombinant factor VIIa].

MEDICAL HISTORY

A 38-yr-old woman suffered from excessive blood loss after elective removal of the uterus because of a leiomyoma. The surgical attempt to stop the bleeding failed. The laboratory evaluation before surgery showed normal coagulation parameters (aPTT 23.4 sec, TPZ > 100 %, platelet count 267 000/microl).

DEVELOPMENT

Despite treatment with the plasminogen activator inhibitor Tranexamic Acid (2 x 500 mg) and 10 units of concentrated platelets as well as 31 units of fresh frozen plasma and 31 units of red blood cell concentrates the bleeding continued. Reaching an cumulative blood loss of 15 000 ml the patient developed ventricular fibrillation necessitating cardiac resuscitation including defibrillation and application of epinephrine 7 mg. At this point systolic blood pressure decreased from 90 to 70 mm Hg, the core temperature was 31,9 degrees C. After successful resuscitation (systolic blood-pressure 90 mm Hg after 15 min) the bleeding started again with a blood loss of 2000 ml requiring 3 units of fresh frozen plasma and 3 red cell concentrates Use of recombinant activated Factor VII (r.FVIIa): 6 mg (300 KiU) r.FVIIa have been applied (92 microg/kgKG [4.6 KiE/kg]). Within 10 minutes the bleeding stopped. More transfusions were not necessary. The patient left the intensive care unit 8 days after the operation without neurological deficit.

CONCLUSION

The use of recombinant Factor VIIa may stop excessive haemorrhage, even if the cause is unknown.
