[Carbon monoxide poisoning from a natural gas burner].

The use of natural gas as a heating source in private homes in Denmark is increasing. Previous case reports describe carbon monoxide poisoning as a result of poor maintenance. Another case is reported here. The family experienced episodes of carbon monoxide intoxication. The woman was six weeks pregnant. Inspection of the gas burner revealed an air inlet blocked by rust debris. Following counselling, the woman elected to have an abortion. Review of the current literature indicates that severe, short-term exposure to carbon monoxide during pregnancy may result in foetal death or serious toxic effects. The current Danish legislation does not specify regular maintenance checks, which are needed to safeguard against future accidents.
