This study was undertaken to elucidate the usefulness and problems of autologous blooddonation for the patients with low-lying placenta. Seventy-eight women with low-lying placentawho gave birth in our institution were retrospectively analyzed. Autologous blood donation wasperformed in 58 patients (74%). The median volume of donated blood was 300 mL. Patients withor without autologous blood donation showed no significant difference in the distance betweenthe edge of the placenta and the internal os of the uterus. Median blood loss due to intrapartumhemorrhage was 1183 mL. All 7 patients with blood loss of more than 2000 mL had donatedautologous blood. The donated blood was transfused in 9 of the 58 patients (16%) who underwentautologous blood donation. No patients underwent allogenic blood transfusion. Althoughautologous blood donation was expected to be useful for avoiding allogenic blood transfusion inthese patients with low-lying placenta, the high discard rate suggests the need for a strategy toselect those patients at high risk for blood loss requiring transfusion.
