title: Autologous blood storage in obstetrics.
abstract: Autologous transfusion, storage of one's own blood for subsequent infusion if needed, is safe and effective in a variety of scheduled operative procedures. Obstetric involvement in such programs is very limited, however. Thirty pregnant women with placenta previa or other potential complications underwent 55 phlebotomies in an autologous transfusion program. Phlebotomies were performed at an average gestational age of 32.4 weeks (range 13-40). Changes in mean diastolic blood pressure and pulse were minimal. Electronic fetal monitoring tracings were normal during the 34 procedures in which it was used. The frequency of mild donor reactions (4%) was consistent with that in nonpregnant donors. After entry into this program, 15 patients received a total of 29 U of packed red blood cells (23 autologous; six homologous). Homologous transfusion was avoided in 86.7% of patients receiving blood. Selected pregnant women can participate safely in autologous blood collection programs, minimizing the need, and therefore the risks, of homologous transfusion.
