Iron preparations are the most frequent cause of pediatric ingestion fatalities. The purpose of this study was to quantify the impression of an increase in iron deaths in young children and to postulate on the reasons. Using the data provided by the American Association of Poison Control Centers, overall annual mortality rate from iron preparations and among children < 6 y was calculated and changes in incidence were recorded. Between 1983 and 1991, there was a 2 to 3-fold increase in the numbers of reported ingestions of iron preparations by toddlers. In the general population the annual mortality rate/100 exposures to iron preparations increased from 0.05 during 1983-1990 to 0.116 in 1991 (p < 0.01). A similar trend was noted in children < 6 y with a rate of 0.004 in 1983-1990 compared with 0.12 in 1991 (p < 0.01). Hence, the increase in mortality was beyond what would be predicted from the increased number of ingestions noted. It is likely that increased awareness of pregnancy-induced anemia results in abundant use of iron pills. These pills have the appearance of candies, which should be changed immediately by legislation. During this period, the volume of iron preparations prescribed increased only marginally (16%), suggesting that over-the-counter use of iron pills increased substantially. In addition to warning labels and child-resistant packaging, an aggressive educational plan directed at the general population and physicians should be instituted immediately.
铁制剂是儿童摄入中毒致死的最常见原因。本研究的目的是量化幼儿铁中毒死亡人数增加的情况,并推测其原因。利用美国中毒控制中心协会提供的数据,计算了铁制剂的总体年死亡率以及6岁以下儿童的年死亡率,并记录了发病率的变化。1983年至1991年期间,学步儿童铁制剂摄入报告数量增加了2至3倍。在普通人群中,每100次铁制剂暴露的年死亡率从1983年至1990年的0.05上升至1991年的0.116(p<0.01)。6岁以下儿童也出现了类似趋势,1983年至1990年的死亡率为0.004,而1991年为0.12(p<0.01)。因此,死亡率的增加超出了因摄入数量增加所预期的范围。很可能是对妊娠性贫血认识的提高导致铁剂的大量使用。这些药丸外观像糖果,应立即通过立法予以改变。在此期间,处方铁制剂的用量仅略有增加(16%),这表明铁剂的非处方使用大幅增加。除了警示标签和儿童安全包装外,应立即针对普通人群和医生制定积极的教育计划。
