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 ...
AFI is the score (expressed in centimetres) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus. To determine the AFI, doctors may use a four-quadrant technique, [ 2 ] when the deepest, unobstructed, vertical length of each pocket of fluid is measured in each quadrant and then added up to the others, [ 3 ] or the ...
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]
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 ...
It is typically diagnosed by ultrasound when the amniotic fluid index (AFI) measures less than 5 cm or when the single deepest pocket (SDP) of amniotic fluid measures less than 2 cm. [1] Amniotic fluid is necessary to allow for normal fetal movement, lung development, and cushioning from uterine compression. [2]
Positive fern test with amniotic fluid as seen under the microscope. The fern test is a medical laboratory test used in obstetrics and gynecology.The name refers to the detection of a characteristic "fern like" pattern of vaginal secretions when a specimen is allowed to dry on a glass slide and is viewed under a low-power microscope.
The presence of these biophysical variables implies absence of significant central nervous system hypoxemia/acidemia at the time of testing. By comparison, a compromised fetus typically exhibits loss of accelerations of the fetal heart rate (FHR), decreased body movement and breathing, hypotonia, and, less acutely, decreased amniotic fluid volume.
A federal investigation found that doctors at both hospitals told Farmer that her fetus would not survive, that her amniotic fluid had emptied and that she was at risk for serious infection or ...
