How do you classify oligohydramnios?
Oligohydramnios has been defined as an amniotic fluid index (AFI) less than 5 cm, although 8 cm has occasionally been used as a cut-off threshold. Because the AFV depends on the gestational age, oligohydramnios has been defined as an AFI less than the fifth percentile (corresponding to an AFI of < 6.8 cm at term).
What is the most common cause of oligohydramnios?
What is the most common cause of oligohydramnios? Several factors can contribute to low amniotic fluid, such as: Congenital anomalies that affect your baby’s kidneys or urinary tract. Problems with your placenta.
What is the range of oligohydramnios?
A sum of less than 5 cm is considered oligohydramnios, 5 to 8 cm is considered borderline, 8 to 20 cm is considered normal, and greater than 20 to 25 cm is considered polyhydramnios.
How is oligohydramnios defined?
Oligohydramnios refers to amniotic fluid volume (AFV) that is less than the minimum expected for gestational age.
What are the complications of oligohydramnios?
- 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)
- Inability of the fetus to tolerate labor, leading to the need for cesarean delivery.
What is the treatment of oligohydramnios?
Low amniotic fluid, also called oligohydramnios, is a serious condition. It happens when the amount of amniotic fluid is less than expected for a baby’s gestational age. There’s no treatment that can completely correct this condition.
What is the nursing diagnosis oligohydramnios?
The term oligohydramnios literally means “scant amniotic fluid” and is diagnosed when an ultrasound reveals an amniotic fluid index (AFI) of less than 5 cm.
What is the volume of amniotic fluid in oligohydramnios?
A normal amniotic fluid index is 5 cm to 25 cm using the standard assessment method. Less than 5 cm is considered oligohydramnios, and greater than 25 cm is considered polyhydramnios.
What is the cause of low amniotic fluid?
Low levels of amniotic fluid are experienced by 8 percent of pregnant woman, (4 percent labeled as having oligohydramnios) and can be caused by a number of different factors, including: Maternal Health Conditions, including dehydration, diabetes, preeclampsia, hypoxia, and more.
What conditions are associated with oligohydramnios?
Factors that are associated with oligohydramnios include the following:
- Premature rupture of membranes (before labor)
- Intrauterine growth restriction (poor fetal growth)
- Post-term pregnancy.
- Birth defects, especially kidney and urinary tract malformations.
- Twin-to-twin transfusion syndrome.
Is oligohydramnios considered high risk?
Oligohydramnios increases the risk of miscarriage or stillbirth. It can also cause the baby to be born with severe abnormalities, including underdeveloped lungs. This is because amniotic fluid plays an essential role in lung development.
Can oligohydramnios be cured?
While there’s no way to prevent oligohydramnios, it’s important to work with your doctor to manage your medications and any conditions linked to low amniotic fluid, including diabetes and high blood pressure.
Is there any medicine for oligohydramnios?
Conclusions: Maternal 1-deamino-[8-D-arginine] vasopressin and oral water administration can reduce and stabilize plasma osmolality and increase amniotic fluid volume. 1-Deamino-[8-D-arginine] vasopressin therapy has potential for the prevention and treatment of oligohydramnios.
What is moderate oligohydramnios?
Amniotic fluid was measured by the amniotic fluid index, and classified as low when between 5.1 and 7.9 cm, moderate oligohydramnios between 3.1 and 5.0 cm, and severe oligohydramnios when less than or equal to 3.0 cm.
What is normal AFI?
Clinical Significance. A normal amniotic fluid index is 5 cm to 25 cm using the standard assessment method. Less than 5 cm is considered oligohydramnios, and greater than 25 cm is considered polyhydramnios.
Is 7 cm amniotic fluid low?
A normal AFI is 5 to 25 cm. An AFI below 5 cm means low amniotic fluid.
What is Potter’s syndrome?
In Potter syndrome, the primary problem is kidney failure. The kidneys fail to develop properly as the baby is growing in the womb. The kidneys normally produce the amniotic fluid (as urine). Potter phenotype refers to a typical facial appearance that occurs in a newborn when there is no amniotic fluid.
How much amniotic fluid is normal at 37 weeks?
Starting from 34 weeks till 40 weeks, 50 ultrasound measurements were available at each gestational age. The mean (standard deviation) of AFI values (in cms) were 34 W: 14.59 (1.79), 35 W: 14.25 (1.57), 36 W: 13.17 (1.56), 37 W: 12.48 (1.52), 38 W: 12.2 (1.7), and 39 W: 11.37 (1.71).
