摘要

目的 统计分析乌鲁木齐地区RhD阴性红细胞血液供应情况，为建立Rh阴性血合理、有效的库存运行模式提供参考，节约稀有血液资源。方法 收集乌鲁木齐市血液中心2017-2021年临床供应红细胞制品和RhD阴性红细胞数据，统计分析乌鲁木齐地区RhD阴性血液用量特点。结果 本中心RhD阴性红细胞供应呈递增趋式，以新鲜红细胞为主，RhD阴性血液血型分布与总体存在明显差异，日常库存单位数A：B：O：AB建议：6：6：8：2。结论 2017-2021年乌鲁木齐地区RhD阴性血临床用量增加，比例高于RhD人群分布比例，通过建立动态库存，达到为临床供应新鲜悬浮红细胞为主、冰冻红细胞为辅的目的，保障稀有血液的合理使用。

Abstract

Objective To statistically analyze the supply of RhD negative red blood cells in Urumqi, so as to provide reference for establishing a reasonable and effective inventory operation mode of RhD negative blood and saving rare blood resources.
Methods The data of clinical supply of red blood cell products and RhD negative red blood cells in Urumqi Blood Center from 2017 to 2021 were collected and analyzed statistically.
Results The supply of RhD negative red blood cells in the center showed an increasing trend, mainly fresh red blood cells. The distribution of RhD negative blood groups was significantly different from that of the general population. A: B: O: AB suggested: 6:6:8:2.
Conclusion   The clinical use of RhD negative blood in Urumqi increased from 2017 to 2021, and the proportion was higher than the distribution proportion of RhD population. Through the establishment of dynamic inventory, the purpose of supplying fresh suspended red blood cells as the main, supplemented by frozen red blood cells for clinical use was achieved, and the rational use of rare blood was guaranteed.
