目的:回顾性分析采血不足量的原因,以减少不足量血液报废率,提高血液质量。方法:对南京市2014-01-05月采集的19 921名献血者中产生的184例不足量血液进行不足量血液构成比、采血过程异常原因以及采集点和采集人员的统计分析。结果:我中心献血不足量比例为0.92%,与标准采集量200 ml相比,标准采集量300ml、400ml产生的不足量率显著增加,差异有统计学意义(P<0.05)。采血过程异常的主要原因是流血不畅,与晕针和其他原因导致的异常相比,差异有统计学意义(P<0.05)。各采集点不足量血液发生率存在一定差异,采集人数较多的场所中以中央采集点不足量采集发生率较低(P<0.05)。结论:为减少献血不良反应的发生,采血人员要积极采取预防措施。
OBJECTIVE: To retrospectively analyze the causes of insufficient blood sampling to reduce the insufficient blood reject rate and improve the blood quality. Methods: A total of 184 blood deficits in 19 921 blood donors collected in Nanjing from January to May in 2014 were analyzed retrospectively. The results showed that the blood composition ratio, the cause of abnormal blood sampling, and the statistical analysis of the collection points and collectors were insufficient. Results: The proportion of insufficient blood donation in our center was 0.92%. Compared with the standard collection quantity of 200 ml, the standard collection quantity of 300ml and 400ml increased significantly, the difference was statistically significant (P <0.05). The main reason for abnormal blood sampling was poor blood flow, and the difference was statistically significant (P <0.05) compared with those caused by fainting and other causes. There was a certain difference in the incidence of blood deficiency at each collection point, and the incidence of insufficient collection at the central collection point was lower in those with larger collection points (P <0.05). Conclusion: In order to reduce the incidence of adverse reactions, blood donors should take active preventive measures.
