A rare cause of perinatal asphyxia: maternal carbon monoxide poisoning.

Carbon monoxide (CO) intoxication has serious adverse effects to the mother and fetus and a result of intrauterine hypoxia, it leads to fetal death or severe neurological sequelae. In this article, a preterm infant who was acutely exposed to CO at the 33rd weeks of gestation before delivery was presented. The baby was delivered by emergent cesarean section at the 34th weeks of gestation due to findings of fetal distress and he had severe hypoxic ischemic encephalopathy leading to death. Results and treatment modalities of CO poisoning during pregnancy were reviewed.
