  High-Risk Pregnancy - Amniotic Fluid Problems / Hydramnios /Oligohydramnios   (Site not responding. Last check: 2007-11-02)
This watery fluid is inside a casing called the amniotic membrane (or sac) and fluid surrounds the fetus throughout pregnancy.
When the amniotic sac ruptures, large amounts of fluid leaving the uterus may increase the risk of placental abruption (early detachment of the placenta) or umbilical cord prolapse (when the cord falls down through the cervical opening) where it may be compressed.
Amniotic fluid is important in the development of fetal organs, especially the lungs.

 Amniotic Fluid | Pregnancy Weekly
Amniotic fluid is a colorless liquid made of water, fetal skin cells, and fetal waste, and is contained within the amniotic sac or "bag of waters" that surrounds your baby.
An excessive amount of amniotic fluid is called polyhydramnios, and is often associated with a multiple pregnancy (twins or triplets), congenital anomalies, or gestational diabetes.
An abnormally small amount of amniotic fluid is known as oligohydramnios, and may the result of a postdate pregnancy, ruptured membranes, placental dysfunction, or fetal abnormalities.

 MedlinePlus Medical Encyclopedia: Amniotic fluid
Amniotic fluid is a clear, slightly yellowish liquid that surrounds the unborn baby (fetus) during pregnancy.
During pregnancy the amniotic fluid increases in volume as the fetus grows.
Amniotic fluid volume is greatest at approximately 34 weeks of gestation, when it averages 800 ml.

 Amniotic Fluid
AFP is present in amniotic fluid which is composed primarily of fetal urine.
Amniotic fluid AFP (AFAFP) may be elevated in open fetal body wall defects, most commonly open neural tube defects (NTD) and open ventral wall defects, due to transudation from exposed fetal vessels and tissue.
Amniotic fluid is examined for the presence of acetylcholinesterase and pseudocholinesterase by using slab gel electrophoresis.

 Amniotic Fluid   (Site not responding. Last check: 2007-11-02)
By the beginning of the second trimester there are 50 cc of fluid in the amniotic sac, and this fluid isn't much different from the baby's plasma, indicating an origin from secretions through the umbilical cord, membrane coverings of the placenta, and even the baby's skin.
The turnover of fluid is fairly rapid, with a build up from urine and a reabsorption from fetal swallowing being important dynamics in the amniotic fluid picture from hour to hour.
When there's little fluid, like in congenital abnormality of the bladder or missing kidneys, the trachea and other respiratory structures don't mature, indicating that the pressure and nature of the fluid bathing these structures is important in their growth.

Too much or too little amniotic fluid is associated with abnormalities in development and pregnancy complications.
Generally, either too much fluid is being produced or there is a problem with the fluid being taken up, or both.
Too much amniotic fluid can cause the mother's uterus to become overdistended and may lead to preterm labor or premature rupture of membranes (the amniotic sac).

 Amniotic Fluid Leakage
Amniotic Fluid is a protective liquid which fills in the sac surrounding the fetus.

On the other hand, many pregnant women do not react to initial amniotic fluid leakage, as they are sure the wetness they sense is from urine incontinence or vaginal discharge, and endanger themselves and their child to be born.
