Amniotic fluid

amniotic

[am″ne-ot´ik] pertaining to the amnion.amniotic band syndrome a condition characterized by isolated or multiple constriction defects of the fingers, toes, limbs, and less frequently the skull, face, or viscera. It results from a tear of unknown etiology in the amnion, which allows amniotic fluid and fetal parts to escape from the amnion into the chorion. When the amnion and chorion are separated, strands from either the maternal amnion or the fetal chorion may entangle fetal parts. As the fetus grows the strands become more constrictive, causing defects.amniotic fluid the albuminous fluid contained in the amniotic sac; called also liquor amnii and, informally, waters. The fetus floats in this fluid, which serves as a cushion against injury from sudden blows or movements and helps maintain a constant body temperature for the fetus. Normally the fluid is clear and slightly alkaline; discoloration or excessive cloudiness may indicate fetal distress or disease, as in erythroblastosis fetalis in which fluid is usually greenish yellow. The amount varies from 500 to 1500 ml.
An excessive amount of amniotic fluid (more than 2000 ml) is called hydramnios; the amount may be as much as several gallons. The cause of this condition is unknown but it frequently accompanies multiple pregnancy or some congenital defect of the fetus, especially hydrocephalus and meningocele.
An abnormally small amount of amniotic fluid is referred to as oligohydramnios; there may be less than 100 ml of fluid present. The cause is unknown. The condition may produce pressure deformities of the fetus, such as clubfoot or torticollis. Adhesions may result from direct contact of the fetus with the amnion.
Removal of a sample of amniotic fluid from the pregnant uterus is called amniocentesis.

amniotic fluid

The fluid that surrounds the foetus in the amniotic sac, which cushions it from injury and plays a central role in foetal development; osmolality, sodium, creatinine and urea content of AF and maternal serum are virtually identical.

Volume
± 800 mL at birth; specific gravity ±1.008; pH, 7.2.
Amniotic fluid analysis
Detect:
• Isoimmunisation of RBCs—Bilirubin levels;
• Genetic defects—Karyotype foetal cells.

Determine foetal maturity—Creatinine, lecithin/sphingomyelin ratio, surfactant.

am·ni·on·ic flu·id

, amniotic fluid (am'nē-on'ik flū'id, am'nē-ot'ik) A liquid within the amnionic sac that surrounds embryo, and later, the fetus and protects it from mechanical injury.
Synonym(s): liquor amnii.

amniotic fluid

A liquid produced by one of the membranes which surround the fetus throughout pregnancy and by fetal urination, in which the fetus floats. The volume of amniotic fluid at full term is usually about 1 litre.

Amniotic fluid

The liquid that surrounds the baby within the amniotic sac. Because it is composed mostly of fetal urine, a low amount of fluid can indicate inadequate placental blood flow to the fetus.Mentioned in: Alpha-Fetoprotein Test, Antepartum Testing, Erythroblastosis Fetalis, Ichthyosis, Obstetrical Emergencies, Premature Rupture of Membranes, Prenatal Surgery, Respiratory Distress Syndrome, Triple Screen

Patient discussion about Amniotic fluid

Q. Is wine or beer safer to drink than liquor? My new girl friend requests me to quit liquor. Is wine or beer safer to drink than liquor?A. Wine or beer is not safer to drink than liquor. Liquor is liquor. A twelve - ounce beer has the same amount of alcohol as a five - ounce glass of wine, or 1.5 - ounce shot of liquor. It is the amount of ethanol consumed that affects a person most, not the type of alcoholic drink.

Q. Is holding liquor a sign of a drinking problem? How can I have a drinking problem if I can hold my liquor? Is holding liquor a sign of a drinking problem?A. "being able to hold your liquor" is actually the liver gathering forces...let's imagine that our liver is a factory that disables alcohol as a poison. and i have a 100 workers over there. if i'll drink great amount of alcohol my workers will be busy and most of the alcohol will run along in my body. but after a few times i'll hire more workers. then less alcohol will run along my body and i'll disable it fast. same thing in your body.

Q. I drink liquor a lot maybe 4x a week and I love drinking but after a couple days my veins star to hurt...Y? It runs in the familly alcohol and bud but I wish I could go a whole year withought poppin bottles.. what will be perscibed to a alki?A. FROM ALL THAT DRINKING
