Abstract:

本研究旨在观察群体性急性可乐定中毒的流行病学特点、临床表现及救治方法,尤其是评价血液灌流(hemoperfusion,HP)治疗急性可乐定中毒的有效性和安全性.通过对北京怀柔4.23急性可乐定中毒事件行流行病学调查,分析所有80例患者的所有流行病学资料,研究病情较重的34例患者的临床表现、治疗方案、预后情况.采用HA230树脂血液灌流器数次HP治疗前后血可乐定、尿可乐定浓度的变化,计算血可乐定浓度下降率,及与常规内科治疗相比HP的排毒效率.观察治疗前患者血压、心率及其他实验室指标如血小板、心肌酶谱、肝酶谱的变化并评价疗效及副作用.研究发现急性可乐定中毒具有隐蔽性强,发病潜伏期短,症状重等特点,HP治疗可显著降低血可乐定水平,短暂升高尿可乐定水平.患者临床症状亦显著改善,血可乐定的下降率为(81±12)%,所有患者经间断HP治疗1~3次后血、尿可乐定水平接近正常.随着患者血可乐定浓度渐趋正常,其临床症状及实验室指标亦能明显改善,短期HP治疗无明显副作用,随访观察半月余,未观察到后遗症.群体性可乐定中毒常常具有危害人群广,症状重,风险大,诊治难度大的特点,重者致人死亡,或者造成社会极大恐慌.研究群体性可乐定中毒有浓厚的军事医学意义,HP是治疗可乐定中毒安全有效的治疗手段.
