| 摘 要： | 对 4年间 6家医院所有门急诊有关敌敌畏、甲胺磷、乐果三种有机磷农药中毒病例进行了调查分析。运用气相色谱法对其血液中的浓度进行测定。采用 Bliss法,计算其死亡率和昏迷率的加权直线回归方程,并获得其经救治后血液半数致死浓度 LC50、半数致昏迷浓度 CC50。综合文献和临床实践,认为及时的救治对中毒病例的治疗转归有较大影响,其自然的血液半数致死浓度应在经救治的半数致死浓度 LC50和半数致昏述浓度之间。综合半数致死浓度和半数致昏迷浓度,计算其自然的半数致死浓度 LCe50值。

| Abstract: | Total cases of organophosphorous (dichlorvos, methamidophos, dimethoate) poisoning outpatients from six hospitals during four years were collected consecutively for lethal blood concentration study. Blood samples were detected with gas chromatography. The probabilities of death, coma were analyzed with Bliss method and their linear regressive equations of probit were obtained respectively, their 50% lethal concentrations (LC50) and 50% coma concentrations(CC50) were calculated by the formulas above. As the death rate was influenced by therapy, its natural death probability has been discussed and estimated their natural LC50 were between the LC50 and CC50 themselves. Combined LC50 and CC50, their natural LC50 were calculated. |
