What Happens If AFI Is High?

Is Polyhydramnios considered high risk?

Polyhydramnios is the term used to describe an excess accumulation of amniotic fluid.

This clinical condition is associated with a high risk of poor pregnancy outcomes 1, 2, 3.

The reported prevalence of polyhydramnios ranges from 0.2 to 1.6 % of all pregnancies 4, 5, 6, 7..

What is a good AFI level?

An AFI between 8-18 is considered normal. Median AFI level is approximately 14 from week 20 to week 35, when the amniotic fluid begins to reduce in preparation for birth. An AFI < 5-6 is considered as oligohydramnios. The exact number can vary by gestational age.

Is Polyhydramnios a reason to induce?

“It is recommended to induce at 38 weeks with a diagnosis of polyhydramnios,” Dr. Trainor said. “The excess fluid around the baby allows the baby to move around more, which creates a greater chance of malpresentation breech position and the baby getting wound up in the umbilical cord.”

Can you have a healthy baby with Polyhydramnios?

Most women with polyhydramnios will not have any significant problems during their pregnancy and will have a healthy baby. But there is a slightly increased risk of pregnancy and birth complications, such as: giving birth prematurely (before 37 weeks)

Should I be worried about Polyhydramnios?

Don’t worry. Most cases of polyhydramnios are mild and generally not dangerous. They’re due to a gradual buildup of amniotic fluid in the second half of pregnancy.

What is the normal AFI at 30 weeks?

From a median of 10.3 cm (range, 8.7-13.7, 5th-95th percentile) at 15 weeks’ gestation, the amniotic fluid index rose progressively to a maximum median of 14.0 cm (range, 4.0-18.6) at 30 weeks. The index then gradually declined to a median of 9.1 cm (range, 4.8-14.2) by 40 weeks’ gestation.

How much amniotic fluid is too much?

As a rule of thumb, polyhydramnios is usually diagnosed with an AFI over 24 or a big pocket of fluid on the ultrasound of over 8 cm. Polyhydramnios is estimated to occur in only about 1 to 2 percent of pregnancies.

How can I decrease amniotic fluid?

Treatment may include:Drainage of excess amniotic fluid. Your health care provider may use amniocentesis to drain excess amniotic fluid from your uterus. … Medication. Your health care provider may prescribe the oral medication indomethacin (Indocin) to help reduce fetal urine production and amniotic fluid volume.

Does Polyhydramnios mean big baby?

A larger than expected fundal height could be a sign of fetal macrosomia. Excessive amniotic fluid (polyhydramnios). Having too much amniotic fluid — the fluid that surrounds and protects a baby during pregnancy — might be a sign that your baby is larger than average.

Can Polyhydramnios cause stillbirth?

As a worst case scenario, too much amniotic fluid is associated with an increased risk of stillbirth. In pregnancies involving normal amniotic fluid levels, 2 out of 1,000 babies are stillborn. With polyhydramnios, it’s 4 out of 1,000 – but that still means that 996 of those 1000 are born alive.

What are the risks of Polyhydramnios?

With polyhydramnios, risk of the following complications is increased:Preterm contractions and possibly preterm labor.Premature rupture of membranes, sometimes followed by abruptio placentae.Fetal malposition.Maternal respiratory compromise.Umbilical cord prolapse.Uterine atony.Postpartum hemorrhage.More items…

How common is Polyhydramnios?

Polyhydramnios occurs in about 1 to 2 percent of pregnancies. Most cases of polyhydramnios are mild and result from a gradual buildup of amniotic fluid during the second half of pregnancy. Severe polyhydramnios may cause shortness of breath, preterm labor, or other signs and symptoms.

What is normal AFI at 34weeks?

From 34 weeks through to labor, the fluid decreases to about 400 ml. Doctors use a scale called the amniotic fluid index (AFI) to check healthy levels of amniotic fluid. AFI measurements are in centimeters (cm). A typical AFI score is 5–25 cm.
