Abstract:Objective This paper discusses the factors that affect the rate of the autologous blood re-transfusion in obstetrics department, and provides references for the indications of the preoperative autologous blood donation and the amount of autologous blood for preoperative autologous blood donation.Methods The clinical data of 161 pregnant women who received preoperative autologous blood donation in our hospital from May 2015 to December 2018 were collected, and the related factors affecting the rate of preoperative autologous blood donation were analyzed by Logistic regression analysis and Logistic regression analysis.Results The total rate of the autologous blood re-transfusion was 60.9%. Univariate analysis results showed that the pregnancy with rare blood,central placenta previa,placenta attaching the scar and suspected placenta accreta(pelvic MRI or pelvic color ultrasonography suggested that placental implantation might be possible) were related factors to the rate of the autologous blood re-transfusion(P<0.01).Multivariate Logistic regression analysis showed that the combination of central placenta previa and suspected placental implantation were independent factors to the rate of the autologous blood re-transfusion(P<0.05).Conclusion Central placenta previa and suspected placenta accreta are independent factors to the rate of the autologous blood re-transfusion.Increasing the prestored blood volume of such pregnant women and reducing the prestored blood volume of pregnant women with only rare blood types can reduce the waste of prestored blood and improve the clinical benefits of the preoperative autologous blood donation.
