				        	Objective To determine the risk factors for autologous blood withdrawal-reinfusion in cesarean section. Methods Parturients who underwent cesarean section and autologous blood withdrawal from August 2012 to June 2015 in our hospital were selected. The preoperative, intraoperative and postop-erative data of the parturients were collected retrospectively from electronic medical records. The parturients were divided into reinfusion group and non-reinfusion group according to whether the parturients received au-tologous blood reinfusion. Logistic regression analysis was used to stratify the risk factors for autologous blood withdrawal-reinfusion in cesarean section. Results A total of 1604 parturients who received autolo-gous blood reinfusion were included in the study, with 757 cases in reinfusion group and 847 cases in non-reinfusion group. Placenta increta∕percreta, placenta previa with previous uterine surgery and complete pla-centa previa were the risk factors for autologous blood withdrawal-reinfusion in cesarean section (P<0. 05). The predictive model was exp( w) ÷ [1 + exp( w)],w = 1. 447 × placenta increta∕percreta ( corrected OR value)+0. 945×complete placenta previa (corrected OR value)+1. 361×placenta previa with previous uter-ine surgery (corrected OR value). The sensitivity and specificity of this model in predicting blood reinfusion were 56% and 79%, respectively, the positive predictive value was 71%, and the negative predictive val-ue was 67%. Conclusion Placenta increta∕percreta, placenta previa with previous uterine surgery and complete placenta previa are high risk factors for autologous blood withdrawal-reinfusion in cesarean section, and routine preparation for autologous blood withdrawal-reinfusion is recommended.
