摘　　要：目的探讨影响产科预存式自体输血回输率的因素,为施行预存式自体输血的适应症及预存自体血量提供参考。方法收集2015年5月—2018年12月于我院施行预存式自体输血的161例产妇的临床资料,应用χ2和Logistic回归分析方法对影响预存自体血回输率的相关因素进行分析。结果预存自体血的总回输率为60.9%,单因素分析显示合并稀有血型、中央性前置胎盘、胎盘瘢痕部位附着、可疑胎盘植入(盆腔核磁提示胎盘植入可能)是预存自体血回输率的相关影响因素(P<0.01)。多因素Logistic回归分析显示合并中央性前置胎盘、可疑胎盘植入是预存自体血回输率的独立影响因素(P<0.05)。结论中央性前置胎盘和可疑胎盘植入是影响预存式自体输血回输率的独立影响因素,增加此类孕产妇预存血量,减少单纯稀有血型孕产妇的预存血量,可减少血液浪费,提高预存式自体输血的临床效益。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.
