目的分析无偿献血者献血后皮下瘀血的原因。方法统计采血中及采血后出现瘀血的献血者人数,并予以追踪随访。结果献血者献血后皮下瘀血率为1.01%(98/9 673)。其中女性献血者的瘀血率(1.20%)高于男性献血者(0.77%),两者具有统计学差异(2χ=4.29,P<0.05)。结论针眼按压不当、冬装袖口太紧,尤其是女性初次献血者精神紧张、恐惧是导致皮下瘀血的主要原因。需进一步加强告知义务和宣传力度,使其充分了解献血后的正确护理方法。
Objective To analyze the causes of subcutaneous bleeding after blood donation in unpaid blood donors. Methods The number of blood donors who stained blood during and after blood collection was counted and followed up. Results Subcutaneous blood stasis after blood donation was 1.01% (98/96 673). The blood stasis rate (1.20%) in female donors was significantly higher than that in male donors (0.77%) (2χ = 4.29, P <0.05). Conclusions The needle eye is not pressed properly, and the winter cuffs are too tight, especially for the female first-time blood donors. The fear is the main reason leading to subcutaneous bleeding. Need to further strengthen the obligation to inform and advocacy efforts to fully understand the correct method of care after blood donation.
