Carbon monoxide intoxication: a review of 14 patients

In 14 cases of carbon monoxide poisoning, medical records were available for retrospective review in which blood samples for carboxyhemoglobin (COHgb) were obtained. Twelve victims (86%) were overcome while at work. Correlation of the clinical picture and COHgb saturation was not always possible although hypertension was not uncommon initially. On follow-up only three patients were mildly hypertensive. Skin or mucous membrane color changes were difficult to detect. Three cases are presented to illustrate factors in the diagnosis and possible sequelae.
