[Risk factors of perinatal blood transfusion].
OBJECTIVE
To investigate the risk factors associated with perinatal packed red blood cell transfusion.


METHODS
We performed univariable analysis and unconditional multivarible logistic regression analysis to identify risk factors associated with perinatal packed red blood cell transfusion in 19 456 obstetrical inpatients.


RESULTS
The transfusion rate was 1.49% (289/19,456). Prenatal hematocrit (HCT) less than 25% (OR 45.3, 95% CI 27.4-74.9), placenta previa (OR 16.8, 95% CI 11.6-24.3), prenatal HCT 25%-30% (OR 11.4, 95% CI 6.7-19.7), ethnic minority (OR 4.8, 95% CI 1.6-14.0), placenta abruption (OR 4.5, 95% CI 1.7-11.5), multiple gestation (OR 2.8, 95% CI 1.6-4.9) and preeclampsia (OR 2.6, 95% CI 1.5-4.4) were risk factors associated with perinatal packed red blood cell transfusion.


CONCLUSIONS
Although the overall perinatal transfusion rate is low, severe prenatal anemia (HCT 25%) and placenta previa can increase the risk of transfusion markedly. It is crucial for obstetricians to provide appropriate perinatal care for those patients.
