RhD阴性孕妇临床备血用血情况分析

Analysis on RBC Preparation and Transfusion of RhD Negative Pregnant Women

目的分析产科RhD阴性孕妇住院期间备血及用血情况,评价产科RhD阴性血液管理的安全性和有效性。方法选取产科住院期间的24938例孕妇作为研究对象,通过“采供血机构信息管理系统”软件,对申请以及输注红细胞的病例进行收集。结果24938例产科住院备血者中RhD阴性备血者2098例,RhD阴性孕妇备血者占产科备血者的8.41%(2098/24938)。产科用血率4.70%(1171/24938),RhD阴性孕妇用血率3.29%(69/2098),平均输注红细胞3.06U(211U/69,只进不舍)。阴性去甘油红细胞解冻率1.86%(39/2098),解冻去甘油红细胞报废率逐年下降。结论库存阴性悬浮红细胞每天各型保持2U或者O型4U即可满足产科临床的常规需求。产科RhD阴性血液管理安全、有效,保障了稀有血液的合理利用。

Objective To analyze the blood preparation and transfusion of Rh D negative obstetric pregnant women during hospitalization and evaluate the safety and the effectiveness of the blood management in Rh D obstetric negative pregnant women. Methods 24 938 cases pregnant women during the period of obstetric hospitalization were selected as the research objects. The data of blood preparation and transfusion were collected through the software of"Information Management System for Blood Collection and Blood Supply Institutions". Results Of the 24 938 cases of inpatient obstetric blood preparation,2 098 were Rh D-negative. Rh D negative maternal blood preparers account for 8. 41 %( 2 098/24 938) of all obstetric blood preparers. The rate of obstetric blood use was 4. 70%( 1 171/24 938) and that of Rh D negative pregnant women was 3. 29%( 69/2 098),average infusion of red blood cells 3. 06 U( 211/69,only in). Negative deglycerol erythrocytes defreeze 1. 86 %( 39/2 098). The scrap rate of thawed negative deglycerin red blood cells decreased year by year. Conclusion The routine clinic requirements of obstetrics can be met by keeping 2 U of each ABO blood type of Rh D negative suspended red blood cells or keeping 4 U of O type every day. Blood management in Rh D negative pregnant women is reasonable,safe and effective,which updates the modern transfusion concept of clinicians and ensures the rational transfusion of rare blood.
