Intrauterine hypoxia

Definition

Intrauterine hypoxia occurs when the fetus is deprived of an adequate supply of oxygen. This may occur with prolapse or occlusion of the umbilical cord, placental infarction and maternal smoking. This can lead to damage of the central nervous system and neonatal encephalopathy, which increases the risk of mortality.
