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).
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 embolism, a condition in which amniotic fluid or other fetal debris enters the maternal circulation, is an extremely rare and catastrophic complication of amniocentesis. [1] Amniotic fluid embolism can result in cardiovascular collapse and has a poor maternal prognosis. [43]
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.
Often referred to as the "water" which surrounds an unborn baby, amniotic fluid plays a vital role in fetal development. Often referred to as the "water" which surrounds an unborn baby, amniotic ...
Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. [1] [2] [3] It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. [4] [5] There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios ...
It is characterized by changes in fetal movement, growth, heart rate, and presence of meconium stained fluid. [4] Risk factors for fetal distress/non-reassuring fetal status include anemia, restriction of fetal growth, maternal hypertension or cardiovascular disease, low amniotic fluid or meconium in the amniotic fluid, or a post-term pregnancy.
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.
