Amniotic Fluid Characteristics
Fluid around baby: Amniotic fluid is the fluid that surrounds and protects the baby. The baby makes the amniotic fluid. How much fluid you drink, how well the placenta works and how the baby is doing all affect how much fluid there is. Too much fluid can be concerning as can too little fluid. ...Read more
Lung Development: Amniotic fluid initially is filtered from the mother's blood and passes through the pregnancy's membranes to create a nourishing cushion during the first few weeks of development. Later, it is a byproduct (urine) of the baby's circulation which is taken into the lungs during the baby's practice breaths. The fluid pressure then induces growth and opening of the lung's branches. ...Read more
Amniotic fluid: Fluid levels change throughout pregnancy. When someone has low fluid we call it oligohydramnios. This is where the total amniotic fluid index is less than 5.0 cmtotal or. The largest verticle measured pocket of fluid is less than 2.0 cm. Levels between 5-10 cm is low normal & can be due to multiple causes including dehydration. Discuss these findings with your md. ...Read more
Diabetes?: Most of the time we don't know what causes polyhydramnios. It is associated with maternal diabetes and can result from trouble with the fetal kidneys or swallowing ability. In and of itself, it isn't harmful, though it can result in cord prolapse if the water breaks through an open cervix. Ask your doctor. ...Read more
Roughly 800 cc: 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). Having said that, amniotic fluid is exchanged between mother and her fetus several times a day. ...Read more
Rest and hydration: There is not a great definitive way to increase amniotic fluid when it is low. Often times complete rest and hydration are recommended. If the pregnancy is close enough to the due date, delivery is recommended because low fluid is often a sign that the placenta is not working well. ...Read more
Amniosintesis: Amniosintesis refers to the removal of a sample of amniotic fluid for analysis. ...Read more
Yes: Amniotic acid is present in amniotic fluid. It is commercially known as allantoin and as such is widely used in various skin products as a moisturizer/softener. It certainly seems to have that effect on newborn skin! ...Read more
ONTD.: Open neural tube defects are the most reliably and commonly diagnosed structural fetal defects from amniotic fluid sampling (increased acetylcholinesterase, Alpha fetao-protein or afp). Others: omphalocele, gastroschisis (all increased afp), chromosomal anomalies, torch infections. ...Read more
What do you suggest if I was considered very healthy and had plenty of amniotic fluid. Anyone know if this is all normal?
Normal: Nothing you said sounds abnormal. Best wishes! ...Read more
Circulation issues: The amniotic fluid 'circulates' inside the uterus after it is manufactured including the baby swallowing some of it. If there are genetic problems with the fetus or problems in 'manufacturing' both can cause low levels. ...Read more
Low amniotic fluid noted on u/s at 7+4w. Is it related to schs or placenta insufficiency? What can I do to increase the amount of fluid in sac?
No intervention: There are no interventions to correct this problem at this gestational age. ...Read more
