The mysterious environment surrounding the fetus for much of his or her life is now being explored with increasing fervor. Assessment of amniotic fluid in the early portion of pregnancy is now possible for fetal karyotype determination. This may permit early diagnosis of abnormal fetuses, increasing the options for patients. As pregnancy progresses, high-resolution ultrasound assessment of amniotic fluid volume is integral to the management of pregnancies at risk for oligohydramnios. Such pregnancies include those who are postdate and those with suspected intrauterine growth retardation. Additional evaluation and ultrasonography are recommended for evaluation of the fetus in this clinical situation. With either hydramnios or oligohydramnios, careful ultrasound assessment of the fetus is essential to rule out significant congenital malformations. Finally, the use of ultrasound-directed amniocentesis in later pregnancy permits an assessment of fetal lung maturity and of the fetus at risk for Rhesus immunization. Attention to detail should increase chances of a successful pregnancy outcome while decreasing neonatal morbidity and mortality.
