目的探讨大学生不足量采血的原因及预防措施。方法 A组各高校大学生参加无偿献血者;B组为同期大连市街头献血屋的无偿献血者。记录两组不足量采血的人数。同时记录大学生献血者初次与再次献血发生不足量的人数。结果 A组中不足量采血率为3.27‰,B组中不足量采血率为1.71‰,经统计学分析,差异有统计学意义(P<0.05)。大学生献血组初次献血不足量人数占3.91‰,再次献血不足量人数占1.57‰,经统计学分析,差异有统计学意义(P<0.05)。结论大学生不足量采血率明显高于街头献血屋的无偿献血者,两者有显著性差异。尤其是初次参加献血的大学生发生不足量采血的人数明显增加,初次与再次献血不足量人数有显著性差异。作者通过分析大学生不足量采血率高的原因,采取相应的预防措施,减少不足量献血的发生,既保护了无偿献血者,又降低了因采血量不足而造成的血液报废,保证血液质量。
Objective To explore the causes and preventive measures of undergraduate insufficient blood sampling. Methods A group of college students to participate in voluntary blood donors; B group for the same period in Dalian blood donation street blood donors. Record the number of insufficient blood draws in both groups. At the same time, record the number of undergraduate student blood donors in the first and second blood donation. Results In group A, the insufficient blood sampling rate was 3.27 ‰, and the insufficient blood sampling rate in group B was 1.71 ‰. The difference was statistically significant (P <0.05). The first donation of blood donation in college students accounted for 3.91 ‰, again less than the amount of blood donation accounted for 1.57 ‰, the statistical analysis, the difference was statistically significant (P <0.05). Conclusions The insufficient blood collection rate of undergraduates is significantly higher than that of blood donors in street blood donors. There is a significant difference between the two. In particular, the number of undergraduate students who participated in blood donation for the first time increased significantly, and there was a significant difference between the initial number and the number of insufficient blood donation again. By analyzing the causes of high blood loss of under-qualified college students, the author takes corresponding preventive measures to reduce the occurrence of insufficient blood donation, which not only protects the blood donors but also reduces the blood waste due to insufficient blood volume to ensure the blood quality.
