What is the management of oligohydramnios?

In singleton pregnancies where oligohydramnios is present without maternal and fetal complications, evidence exists that either oral or intravenous maternal hydration (1500-2500 mL/day) is associated with a 20-30% improvement in AFI and a reduction in cesarean delivery.

How do you treat low amniotic fluid during pregnancy?

A doctor may treat low levels of amniotic fluid with a process called amnioinfusion. For this treatment, the doctor will introduce a saline solution via the cervix into the amniotic sac to increase fluid levels.

What is the treatment for low amniotic fluid oligohydramnios?

Answer From Yvonne Butler Tobah, M.D. Low amniotic fluid (oligohydramnios) is a condition in which the amniotic fluid measures lower than expected for a baby’s gestational age. No treatment has been proved effective long term.

When do you deliver patient with oligohydramnios?

Oligohydramnios at 34-36 weeks: observe or deliver.

What is oligohydramnios antepartum?

What is oligohydramnios? In this condition, there is too little amniotic fluid around your baby during pregnancy. This occurs in only about 4% of pregnancies. Your baby needs amniotic fluid to grow. This watery fluid is inside the amniotic sac (membrane).

Can dehydration cause oligohydramnios?

These results indicate that maternal dehydration may have marked effects on maternal-fetal-amniotic fluid dynamics, possibly contributing to the development of oligohydramnios.

Does bed rest help with low amniotic fluid?

But some doctors will still prescribe it in the case of low amniotic fluid. Resting in bed or on the couch (except to go to the bathroom or shower) may help improve blood flow to the placenta, which in turn helps increase amniotic fluid.

Can a baby survive in low amniotic fluid?

These babies require intensive breathing support and sometimes do not survive due to poor lung development. Babies who develop low amniotic fluid after 23 to 24 weeks, however, usually have adequate lung tissue, even if the fluid levels become very low in later pregnancy.

What are the signs and symptoms of oligohydramnios?

Signs and symptoms of oligohydramnios

  • Leaking of the amniotic fluid.
  • Low amniotic fluid on an ultrasound.
  • Measurements of size smaller than what is normal for gestational age.
  • Low maternal weight gain.
  • Prelabor Rupture of membranes.
  • Abdominal discomfort.
  • Sudden drop in fetal heart rate.

What conditions are associated with oligohydramnios?

Oligohydramnios is also associated with meconium staining of the amniotic fluid, fetal heart conduction abnormalities, umbilical cord compression, poor tolerance of labor, lower Apgar scores, and fetal acidosis.

What are complications of oligohydramnios?

Complications of oligohydramnios include the following:

  • Fetal death.
  • Intrauterine growth restriction.
  • Limb contractures (if oligohydramnios begins early in the pregnancy)
  • Delayed or incomplete lung maturation (if oligohydramnios begins early in the pregnancy)

When to start antenatal surveillance for oligohydramnios?

Management decisions are more challenging in cases with oligohydramnios as the only abnormality in antenatal surveillance. Most experts agree that the best course of action with a finding of isolated and uncomplicated oligohydramnios is expectant management if gestational age is <36 0/7 weeks and delivery if gestational age is >36 completed weeks.

What are the causes of oligohydramnios in pregnancy?

Oligohydramnios is associated with many conditions/complications of pregnancy, and the differential breaks down into the following categories: maternal, fetal, placental, and idiopathic. [4] Maternal causes: Oligohydramnios has correlations with any medical or obstetric condition leading to uteroplacental insufficiency (8% of all gestations).

When do you get a diagnosis of oligohydramnios?

Fetal genitourinary abnormalities can, therefore, result in a diagnosis of oligohydramnios after 16 to 20 weeks gestation. Examples include bladder outlet obstruction, dysplastic kidneys, and renal agenesis.

What should the modified biophysical profile be for antepartum?

An amniotic fluid index of more than 5 cm is thought to be an adequate volume of amniotic fluid. The modified biophysical profile is considered normal if the nonstress test is reactive and the amniotic fluid index is greater than 5 cm and abnormal if the nonstress test is nonreactive or the amniotic fluid index is 5 cm or less.
