一、气燃气中毒的原因与发病机理1.天燃气的成分与中毒特点:天燃气中的主要成份为烷、烯、炔类及硫化氢等物.由于所含的成分不同而中毒所引起的临床表现也不同。如硫化氢引起中毒的特点是对眼及上呼吸道粘膜的刺激症状为主,而炔类如乙炔有特殊的气味,在高浓度时有麻醉作用,但在急性中毒中偶见。烯类中毒在高浓度可起麻醉作用,但呼吸影响较小。烷类中,丙烷与丁烷在天燃气中含量基微,主要为甲烷
First, the causes of gas poisoning and pathogenesis 1. Natural gas composition and poisoning characteristics: Natural gas in the main components of alkanes, alkenes, alkynes and hydrogen sulfide and other substances due to the different components of the poisoning caused Clinical manifestations are also different. Such as hydrogen sulfide poisoning is characterized by irritation of the upper respiratory tract and mucous membrane symptoms, while alkynes such as acetylene have a special smell, anesthesia at high concentrations, but occasionally acute poisoning. Alzheimer’s poisoning can occur at high concentrations but with less respiratory effects. Alkanes, propane and butane content in natural gas base micro, mainly methane
