How many liters of amniotic fluid is normal?
How many liters of amniotic fluid is normal?
While in the womb, the baby floats in the amniotic fluid. The amount of amniotic fluid is greatest at about 34 weeks (gestation) into the pregnancy, when it averages 800 mL. About 600 mL of amniotic fluid surrounds the baby at full term (40 weeks gestation).
What percent of amniotic fluid is normal?
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.
How much amniotic fluid is produced daily?
By term, a fetus produces on average from 500 to 700 ml/day with a slight decline in hourly fetal urine production after 40 weeks’ gestation. Amniotic fluid is eliminated by at least three mechanisms. The primary source of elimination is through fetal swallowing, which has been observed as early as 16 weeks.
What AFI is polyhydramnios?
An alternative way of measuring amniotic fluid is measuring the largest pocket in four specific parts of your uterus. The sum of these measurements is the amniotic fluid index (AFI). An AFI of 25 centimeters or more indicates polyhydramnios.
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.
Can polyhydramnios affect baby?
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)
