title: Autologous blood donation with placenta previa: is it feasible?
abstract: Autologous blood donation has been recommended for patients with placenta previa. We hypothesized that premature delivery, preexisting anemia, and bleeding would limit its utilization. We reviewed the charts of all patients admitted with placenta previa between July 1, 1989, and April 30, 1992. To be eligible for autologous donation we assumed that the patient would need to be asymptomatic with a hematocrit 34% or higher at 32 weeks' gestation. Eighty-eight patients were admitted with placenta previa, 12 (14%) of whom were eligible for autologous donation. Two eligible patients required transfusion at delivery and four delivered prior to 34 weeks. Few patients with placenta previa are eligible for autologous donation and although two would have used their autologous units, twice as many may have been compromised by recent autologous donation. We conclude that autologous donation is not feasible in a majority of patients with placenta previa and is of limited usefulness in its management.
