液化石油气与煤气中毒检验的异同

目的 研究液化石油气与煤气中毒鉴定的异同。方法 将实验小白鼠、SD大鼠及家兔分别经液化石油气和煤气染毒,测定中毒后血中碳氧血红蛋白饱和度(HbCO%)及丙烷。结果 煤气中毒家兔体内碳氧血红蛋白饱和度达及49.95%;煤气中毒死亡小白鼠及大鼠体内HbCO%大于60%;液化石油气中毒死亡的家兔、小白鼠及大鼠血中检出丙烷,而体内HbCO%与正常的家兔、小白鼠及大鼠体内HbCO%无明显差异。结论 煤气中毒可通过测定其体内HbCO%进行鉴定;液化石油气中毒后体内HbCO%未见明显升高,可通过测定血中丙烷进行鉴定。

Difference between Identification for Liquefied Petroleum Gas Poisoning and for Coal Gas Poisoning

Objective To study the difference betweenidentification for liquefied petroleum gas (LPG) poisoning andfor coal gas poisoning. Methods The percent carboxyhemo-globin saturation(HbCO%) and propane in blood of miceand rabbits were determined respectively after they were poi-soned by LPG and coal gas. Results The HbCO% in thepoisoned rabbits by coal gas was 49.95%, and the HbCO% inthe poisoned death mice > 60%; The propane was qualitativein the poisoned rabbits and mice by LPG, and the HbCO%was the same in the natural rabbits and mice. ConclusionCoal gas poisoning can be identified by determining theHbCO%, and LPG poisoning can be identified by determiningthe propane.
