What is clinical smoke poisoning

In this 13-year study, 51 patients were admitted with the primary diagnosis of "smoke poisoning" "carbon monoxide (CO) poisoning" or "respiratory burns." Forty patients (78%) had diagnosis of smoke poisoning with minor or no skin burns. The study indicated that clinical diagnosis of CO poisoning cannot be made reliably without carboxyhemoglobin (COHg) determination and that smoke poisoning patients often had CO poisoning. Seventeen of 19 smoke poisoning patients (89%) had CO poisoning above COHb levels of 15% saturation. Carbon monoxide was successfully removed from the blood by improving alveolar ventilation and oxygen concentration. However, there were 2 smoke poisoning deaths as the result of gaseous chemical injury. There was a correlation coefficient of 0.87 between initial COHg levels and patients' hospital days primarily determined by patients' pulmonary complications. Since CO is non-irritating, COHb levels may be used as an additional indicator of suspected pulmonary injury by noxious combustion gases. Language: en
