【摘要】：目的查明江西省某小学一起聚集性呕吐事件原因。方法病例定义:2013年9月13日至18日,在某小学学生中,出现呕吐、头痛、头晕、恶心、腹痛症状之一者。病例搜索采用各班级班主任分别询问的方式开展。原因探查采用回顾性队列研究,选择发病班级集中的三年级一班的所有学生为研究对象,回顾调查学生铁树果进食史及剂量。结果共搜索到病例18例,全部为学生,病例分布在2个班级,发病班级罹患率为19%(18/97),病例集中在4 h内发病,临床症状主要为呕吐(78%)、头晕(67%)、恶心(50%)、腹痛(44%)。61%(11/18)的病例乳酸脱氢酶升高,检测值中位数为286 U/L(范围:263~369 U/L);22%(4/18)的病例出现凝血4项异常;17%(3/18)的病例出现白细胞升高,检测值中位数为12×109/L,范围:(11~13)×109/L。食用铁树果是发病的主要危险因素(RR=+∞,Fisher确切概率P=0.00008)。结论本次聚集性呕吐事件为食用铁树果导致的中毒事件。

Methods case definition: from September 13 to 18, 2013, one of the symptoms of vomiting, headache, dizziness, nausea and abdominal pain appeared in a primary school student. Case search was carried out in the form of inquiry by each class head teacher. A retrospective cohort study was used to investigate the history and dose of iron tree fruit intake. Results A total of 18 cases were found, all of them were students. The incidence of Ldehydrogenase was 19% (18 / 97) in two classes. The clinical symptoms were vomiting (78%), dizziness (67%), nausea (50%), abdominal pain (44%) and abdominal pain (1.61%). The incidence rate of lactate dehydrogenase in the class was 19% (18 / 97). The main clinical symptoms were vomiting (78%), dizziness (67%), nausea (50%), abdominal pain (44%) and abdominal pain (1.61%). The median detection value was 286 UP / L, 22% (4 / 18) and 17% (3 / 18) with leukocytosis. The median value was 12 脳 10 9 / L, and the range was (1113) 脳 109%. Eating iron fruit was the main risk factor (RR = 鈭，
