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。
Objective To study the similarities and differences between liquefied petroleum gas and gas poisoning identification. Methods Experimental mice, SD rats and rabbits were exposed to liquefied petroleum gas (LPG) and coal gas respectively for measurement of blood carboxyhemoglobin saturation (HbCO%) and propane after poisoning. Results The degree of saturation of carboxyhemoglobin reached 49.95% in gas poisoning rabbits, and the HbCO% in mice and rats died of gas poisoning was more than 60%. Propane was detected in the blood of rabbits, mice and rats who died of liquefied petroleum gas poisoning , While in vivo HbCO% and normal rabbits, mice and rats in vivo HbCO% no significant difference. Conclusion Gas poisoning can be identified by measuring the HbCO% in the body. After the liquefied petroleum gas is poisoned, there is no obvious increase of HbCO% in the body, which can be identified by measuring propane in the blood.
