The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...
Amniotic fluid is mildly basic (pH 7.1–7.3) compared to normal vaginal secretions which are acidic (pH 4.5–6). [10] Basic fluid, like amniotic fluid, will turn the nitrazine paper from orange to dark blue. [9] Fern test: A sterile cotton swab is used to collect fluid from the vagina and place it on a microscope slide.
An amniotic fluid embolism (AFE) is a life-threatening childbirth emergency in which amniotic fluid enters the blood stream of the mother, triggering a serious reaction which results in cardiorespiratory (heart and lung) collapse and massive bleeding (coagulopathy).

If the lack of amniotic fluid prevents accurate visualization on ultraosund, MRI imaging can be considered. Genetic testing can be useful if fetal anomalies are documented on imaging. An elevated maternal serum alpha fetal protein (MSAFP) can indicate leaking amniotic fluid due to damage to fetal membranes or the placenta. This is associated ...
The rupture is usually at the bottom of the uterus, over the cervix, causing a gush of fluid. This gush may be quite small (such as 50ml), or it can be significantly large (200-300ml) depending upon amount of fluid in the amniotic sac, and to what extent the fetal head is plugging the hole and retaining fluid in the sac.

Leaking or rupture of membranes: Leaking or rupture of membranes may be caused by a gush of fluid or a slow constant trickle of fluid. This is due to a tear in the membrane. Premature rupture of membranes can also result in low amniotic fluid levels. Placental problems: Placental problems may cause low amniotic fluid. If the placenta is not ...
An obstetric labor complication is a difficulty or abnormality that arises during the process of labor or delivery.. The Trust for America's Health reports that as of 2011, about one third of American births have some complications; many are directly related to the mother's health including increasing rates of obesity, type 2 diabetes, and physical inactivity.
