FETAL ASPHYXIAL STATES /

IUGR AND OLIGOHYDRAMNIOS

The association of chronic fetal compromise and oligohydramnios is well recognized. Two clinical conditions are associated with a high incidence of placental dysfunction leading to dysmaturity:

• Intrauterine growth retardation (IUGR).
• The oligohydramnios appears to be the result of the etiology and rate of progression of the growth failure.
• The fetus with IUGR unrelated to primary placental failure and mild dysmature IUGR are likely to have normal amniotic fluid volume.
• The fetus with severe dysmature IUGR or with decompensation of the usual fetal adaptive methods will always have oligohydramnios.
• Postmaturity syndrome.

Oligohydramnios, which may be severe, is commonly seen in both conditions.
