Endosulfan, an organochlorine insecticide widely used in agriculture, is rapidly absorbed following ingestion, inhalation, or skin exposure. Poisonings rarely result in morbidity and mortality. Symptoms occur rapidly following exposure with CNS toxicity. Endosulfan has been banned in many countries; however, it is still used in the United States.
A 2.5-year-old ingested an unknown amount of endosulfan from a 20-ounce soft drink bottle. He immediately developed generalized tonic-clonic seizure activity and became unresponsive. He was transferred to the local hospital and to a tertiary children's hospital where the seizures were refractory to treatment despite treatment with multiple anticonvulsants. He became hypotensive requiring vasopressors. On day 3, an MRI showed cerebral edema, and a nuclear medicine flow scan failed to show blood flow to the brain and he was pronounced dead.
This is the first published pediatric death in the United States because of endosulfan. Central nervous system stimulation is frequently the presenting symptom with or without other organ dysfunction. Status epilepticus causes the highest morbidity and mortality, therefore prompt administration of anticonvulsant drugs is important although not always effective. The child is our case demonstrated the most severe features of endosulfan exposure.
In summary, prevention of a potentially toxic exposure is critical. The presence of this substance in a soft drink bottle contributed to the toxic exposure in this child, thus emphasizing the need for poison prevention education. The severe toxicity to those exposed raises the question of the need of this compound on the U.S. market.
硫丹是一种广泛用于农业的有机氯杀虫剂,经口摄入、吸入或皮肤接触后可迅速被吸收。中毒很少导致发病和死亡。接触后会迅速出现中枢神经系统毒性症状。硫丹在许多国家已被禁用;然而,它在美国仍在使用。
一名2.5岁儿童从一个20盎司的软饮料瓶中摄入了未知量的硫丹。他立即出现全身性强直阵挛性癫痫发作并失去意识。他被转至当地医院,后又转至一家三级儿童医院,尽管使用了多种抗惊厥药物治疗,但癫痫发作仍难以控制。他出现低血压,需要使用血管升压药。第3天,磁共振成像显示脑水肿,核医学血流扫描未显示脑部有血流,随后他被宣告死亡。
这是美国首例因硫丹导致儿童死亡的公开报道病例。中枢神经系统刺激常常是主要症状,可伴有或不伴有其他器官功能障碍。癫痫持续状态导致的发病率和死亡率最高,因此尽管抗惊厥药物并非总是有效,但及时给药很重要。我们病例中的这名儿童展现了硫丹暴露的最严重特征。
总之,预防潜在的有毒暴露至关重要。软饮料瓶中存在这种物质导致了该儿童的有毒暴露,从而凸显了预防中毒教育的必要性。该化合物对接触者的严重毒性引发了其在美国市场是否有必要存在的问题。
