|The objective of the work was to evaluate quantitatively hydrogen cyanide (HCN) and carbon monoxide (CO) determinations in the blood of 35 fatal cases who were convicts in a state prison. Deaths were caused by inhalation of combustion gases produced during the burning of polyurethane mattresses.
Carbon monoxide results were expressed as the percentage of carboxihemoglobin over total hemoglobin, showing values between 4 and 18% with an average of 9% for n = 35. Hydrogen cyanide showed values between 2.0 and 7.2 mg per liter of blood with and average of 3.5 mg/l for n = 35. Other components with toxicogenic relevance such as ethanol, methanol, aldehydes and other volatile compounds gave negative results for the 35 cases. Consumer drugs and psychotropics were negative, as well.
