自我市开展无偿献血活动以来,陆续有来自各行各业的5000余人到血站献血。有少部分人在献血时出现晕厥现象,症状有不同程度的头晕、眼花、恶心、面色苍白或出冷汗等,甚至发生晕厥。经观察发现,首次献血时发生晕厥的机会较多,且男性发生机率高于女性。晕厥的发生与献血时的采血量无明显关系。通过对85例晕厥者的调查统计,分析其发生原因,综述如下:(见表1)。 Since the city launched unpaid blood donation activities, more than 5,000 people from various walks of life have successively donated blood to blood stations. A small number of people experienced syncope when they donated blood. Symptoms were dizziness, vertigo, nausea, pale or cold sweats, and even fainting. It has been observed that there are more chances of syncope when the first blood donation occurs, and the probability of occurrence of a man is higher than that of a woman. The occurrence of syncope was not significantly related to the amount of blood collected during blood donation. Through the investigation and statistics of 85 cases of syncope, the causes were analyzed and summarized as follows: (See Table 1).
