Abstract

This study assessed risk factors for blood transfusion after Cesarean section in patients with partial placenta previa. We retrospectively reviewed the medical records of 149 patients who underwent Cesarean sections for partial placenta previa between January 2010 and October 2021. Clinical characteristics were compared between the two groups: the blood transfusion group (n=22), defined as patients who received a blood transfusion during surgery or within 24 hours after surgery, and the non-blood transfusion group (n=127), which included other patients. Multivariable logistic regression analysis identified two risk factors independently associated with blood transfusion: antenatal hemorrhage (adjusted odds ratio [aOR], 16.283; 95% confidence interval [CI], 4.405-60.190; P<0.001) and preoperative hemoglobin (g/dL) (aOR, 0.427; 95% CI, 0.246-0.739; P=0.002). Thus, patients who are at risk for these two factors should be carefully managed with sufficient preparation for blood transfusion and anesthetic management.
