Abstract: 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.

Key words: liquefied petroleum gas, coal gas, HbCO, propane

摘要： 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。
