Technique. It's a standard way of checking on your baby's health. normal range of amniotic fluid index or AFI is 8 to 18 centimetre . Modified from Moore TR, Cayle JE: The amniotic fluid index in normal human pregnancy. The deepest (maximal) vertical pocket (DVP) depth is considered a reliable method for assessing amniotic fluid volume on ultrasound 1,2.It is performed by assessing a pocket of a maximal depth of amniotic fluid which is free of an umbilical cord and fetal parts.. Some researchers feel one good … This is a threatened miscarriage. Doctors can measure the amount of fluid through a few different methods, most commonly through amniotic fluid index (AFI) evaluation or deep pocket measurements. An AFI<5-6 is considered as oligohydramnios. Reference Ranges of Amniotic Fluid Index in Late Third Trimester of Pregnancy: What … Amniotic fluid index (AFI) is a quantitative estimate of amniotic fluid and an indicator of fetal well-being. The "load" of pregnancy isn't just the baby. The membrane is also commonly referred to as the "bag of waters." Am J Perinatol 1996;13:231-234. Dizon-Townson D, Kennedy KA, Dildy GA et.al. Pregnancy outcomes of a borderline versus normal AFI suggest an increased risk of meconium‐stained fluid, intrauterine growth restriction, cesarean delivery for a nonreassuring fetal heart rate, low Apgar scores, and neonatal intensive care unit admission with borderline fluid. Generally speaking, an AFI between 8-18 is considered normal. It develops as a fluid-filled extracelomic cavity identified near the time of implantation even before the embryo is recognized ().Its functions include nutritive, protective, and diagnostic functions (1 –3).In some abnormal cases, the AF volume may be more or less than expected. The sum of the four quadrants, in millimeters or centimeters, is amniotic fluid index. Very low values are associated with intrauterine growth restriction and renal anomalies of fetus, whereas high values may indicate fetal GI anomalies, maternal diabetes mellitus, and so forth. Generally speaking, an AFI between 8-18 is considered normal. J Obstet Gynaecol Res … The fht is good. Usually, the normal value of amniotic fluid index varies from 50 mm to 250 mm (or 5 cm ... a small tube can be placed in the bladder to allow the fluid to flow into the amniotic sac. The index is determined by performing ultrasound examination of the uterus. The normal amount of amniotic fluid index is between 8 to 18 centimeters. It can serve as an indicator of fetal well-being. It is part of the fetal biophysical profile.. An AFI of less than 5 to 6 centimeters leads to a condition called oligohydramnios, which means that amniotic … There's considerable weight and volume contributed by the placenta and the amniotic fluid. There are a few ways to estimate amniotic fluid volume.

Moore and Cayle subsequently assessed the amniotic fluid index in 791 normal pregnancies between 16 and 42 weeks. Though there are several ways to assess quantity of amniotic fluid ranging from clinical palpation to measurement of single deepest vertical pocket , amniotic fluid index (AFI) by four-quadrant technique as described by Phelan et al.
