[A case of acute poisoning with thiamethoxam]

Thiamethoxam belongs to the second generation of neonicotinoid insecticides, and case of acute poisoning with thiamethoxam had never reported in China. This paper reviewed a case of oral poisoning with thiamethoxam pesticides, the patient suffered vomiting, generalized convulsions, confusion, and decreased oxygen saturation. After treated with gastric lavage, ventilator support, and the use of propofol, midazolam, sodium phenobarbital, and sodium valproate, the convulsions could not be controlled. Untill treated with penehyclidine hydrochloride and hemoperfusion combined with hemofiltration, the patient finally recovered and was discharged from the hospital. We suggest that the main treatments for acute severe thiamethoxam poisoning are decontamination and symptomatic support, pentoxifylline hydrochloride and hemoperfusion combined with hemofiltration may improve the patients' prognosis.噻虫嗪属于第二代新烟碱类杀虫剂，其急性中毒病例国内未见报道。本文回顾1例患者口服噻虫嗪中毒后出现呕吐、全身抽搐、神志不清、氧饱和度下降。经洗胃、呼吸机支持，并使用丙泊酚、咪达唑仑、苯巴比妥钠、丙戊酸钠仍无法控制抽搐。后予盐酸戊乙奎醚和血液灌流联合血液滤过治疗，患者最终康复出院。结合已发表的新烟碱类中毒文献，我们建议急性重度噻虫嗪中毒主要的治疗是洗消和对症支持治疗，盐酸戊乙奎醚和血液灌流联合血液滤过治疗可能改善患者预后。.
