[The effect of high temperature on the levels of selected endogenous compounds].

The authors present their research on the levels of carboxyhemoglobin, hydrogen cyanide and ethyl alcohol in the blood of 23 fatalities found in the extreme conditions (methane explosion, fire, high temperature) associated with a mining disaster. Determinations of the presence of carboxyhemoglobin, hydrogen cyanide, and ethyl alcohol were performed as soon as the blood samples were collected from the deceased. The concentration of ethyl alcohol ranged from 0.2 per thousand to 1.3 per thousand in 18 cases. Blood HbCO levels tested within the range of 11% to 83% in 17 cases. In six cases, HbCO tested negative, and the injuries found at autopsy indicated these individuals to have been killed at the moment of the explosion. Blood cyanide content tested negative in all the examined cases. The extreme conditions of the mining disaster, especially high temperature, to which the bodies were exposed, did not have any effect either on endogenous cyanide or carboxyhemoglobin, causing, however, a significant increase in the level of ethyl alcohol in the blood.
