![]() ![]() Low amniotic fluid glucose concentration Was considered < 15 mg/dl. Results: The diagnosis of clinical chorioamnionitis was made in 25 (15/60) of women entered into the study. The normal range for amniotic fluid volumes varies with gestational age. Subjects were studied prospectively for the development of positive amniotic fluid cultures and the development of clinical chorioamnionitis. Amniotic pressure was raised in all those with a deepest pool of greater than 15 cm, and was normal in all with a deepest pool less than 15 cm. ![]() ![]() An amniotic fluid index was then obtained for each gestational sac. The dividing membrane between twin fetuses was identified. Study design: Four hundred eighty-eight patients with normal diamniotic twins were examined between 14 and 40 weeks gestation. normal AFI values range from 5 to 25 cm Objective: We sought to investigate the amniotic fluid index for individual gestational sacs of twin pregnancies.the sum of all the four quadrant measurements is the AFI.measurement of the four pockets is in centimeters.the deepest pocket devoid of an umbilical cord and fetal parts is measured in the vertical dimension.Amniotic fluid helps promote pulmonary and urinary tract development and also acts as a cushion to protect the fetus from injury. AFI > 8.1-24 was regarded as normal AFI > 24 was considered as polyhydramnios. This clear, yellowish fluid is normally contained within the amniotic sac. Normally, the level of amniotic fluid is at its highest around 36 of pregnancy, measuring around 1 quart. Background and purpose of study: Amniotic fluid volume varies according. Both methods are qualitative measures of the AF and may be a poor reflection of the actual amniotic fluid volume 14. the uterus is divided into four imaginary quadrants with the linea nigra and a mediolateral line running through the umbilicus acting as the vertical and the horizontal axes respectively Amniotic Fluid has multiple roles during pregnancy. A nother method for assessing the AF, called the Amniotic Fluid Index (AFI), uses the sum of the deepest vertical pocket of fluid found in each quadrant of the uterus the normal range for the AFI is 5 to 25 cm 12,13.The amniotic fluid index (AFI) is an estimate of the amniotic fluid volume in a pregnant uterus. It is part of the fetal biophysical profile. ![]()
