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.
自体输血，即储存自身血液以备后续需要时输注，在各种预定的手术操作中是安全有效的。然而，产科参与此类项目的情况非常有限。30名患有前置胎盘或其他潜在并发症的孕妇在一个自体输血项目中接受了55次静脉采血。静脉采血的平均孕周为32.4周（范围13 - 40周）。平均舒张压和脉搏的变化很小。在使用电子胎儿监护的34例操作中，监护结果正常。轻度供血者反应的发生率（4%）与非孕妇供血者一致。进入该项目后，15名患者共接受了29单位的浓缩红细胞（23单位自体血；6单位异体血）。86.7%接受输血的患者避免了异体输血。选定的孕妇可以安全地参与自体采血项目，从而将异体输血的需求及风险降至最低。
