Amniotic fluid index is the summation of the vertical diameter of the largest pocket in each of the four quadrants as proposed by Phelan and Rutherford.

. The linea nigra is used to divide the uterus into right and left halvesThe umbilicus serves as the dividing point for the upper and lower halves. Doctors commonly measure the depth of the fluid in four quadrants in the uterus and add them up.

Decreased fetal urine output can have a number of causes which fall into two general categories. The amniotic fluid index is measured by dividing the uterus into four imaginary quadrants Figure 1. This method of measuring amniotic fluid is referred to as the amniotic fluid index AFI. Amniotic Fluid Index AFI An ultrasound procedure used to asses the amount of amniotic fluid.

The amniotic fluid index AFI is an estimate of the amniotic fluid volume in a pregnant uterus. Amniotic fluid index measurements during pregnancy. 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. The amniotic fluid index is used in patients who are at least 24 weeks pregnant with a singleton gestation.

It estimates the amount of amniotic fluid in the fetal sac to make sure there isnt too much a condition called polyhydramnios or too little a condition called oligohydramnios. The amniotic fluid index AFI is the estimated range of possible volume of fluid in the amniotic sac. Typically the AFI calculation is determined as part of routine ultrasound examinations somewhere around the 20th week of pregnancy or a little later. The amniotic fluid index AFI is a test often performed weekly toward the end of pregnancy in women with high blood pressure diabetes or other medical problems.

Biophysical profile helps in evaluation of the fetal well-being. They include amniotic fluid index AFI and deep pocket measurements. Another 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 1213Both methods are qualitative measures of the AF and may be a poor reflection of the actual amniotic fluid volume 14. How the Test Is Done Your doctor or a lab technician will estimate your amniotic fluid.

It is a separate measurement from the biophysical profile. While previous reports have outlined this technique and correlated the results with pregnancy outcome none have reviewed the. Amniotic fluid protects the fetus from temperature extremes and from being bumped or hurt as the mother moves around.

Hemoglobin levels in pregnancy calculator.

It is part of the fetal biophysical profile. Count worksheets maker 1-10 Crown-heel length CHL calculator. SDP stands for Single Deepest Pocket and it is the measurement in centimeters of the deepest pocket in just one quadrant. AFI is the score expressed in cm given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus.

Nuchal translucency NT chart. The amniotic fluid index AFI is a measurement and scale of the amount of amniotic fluid present in the womb while a woman is pregnant. Amniotic fluid index AFI is a quantitative estimate of amniotic fluid and an indicator of fetal well-being. Amniotic Fluid Index AFI is the sum total measurement in centimeters of the deepest pocket of amniotic fluid in each of the four quadrants of the uterus.

The amniotic fluid index is a standardized way to assess the sufficiency of amniotic fluid quantity in pregnancy. Healthcare workers including the nurse practitioner who follow pregnant patients must be aware of the amniotic fluid index. SDP is also referred to by other names such as deepest vertical pocket DVP deepest pool maximum. Singleton Amniotic Fluid Index.

29 rows The amniotic fluid index or AFI is used to estimate the well-being of. Abnormal value of AFI may result into fetal and maternal disorders. Amniotic fluid volume assessment has become an important part of antepartum fetal surveillance. Enhancing Healthcare Team Outcomes.

Interest in fluid levels might occur earlier if the measurement is likely. The amniotic fluid index is a standardized way to assess the sufficiency of amniotic fluid quantity in pregnancy. A normal amniotic fluid index is 5 cm to 25 cm using the standard assessment method. If fluid levels add up to more than 25 centimeters she has polyhydramnios.

If the amniotic fluid depth measures less than 5 centimeters the pregnant woman has oligohydramnios or polyhydramnios. The amniotic fluid index AFI or four-quadrant technique has been suggested for this purpose. Prenatal ultrasound can predict pregnancy outcome. The amniotic fluid index is used in patients who are at least 24 weeks pregnant with a singleton gestation.

Amniotic fluid index is a way of measuring the amount of liquid that is around a baby fetus in the uterus during pregnancyIt is usually done as part of the biophysical profile BPP which is a series of tests that measure the health of the baby during pregnancy. Well get into the specifics in a minute but be aware that this number is usually VERY important in pregnancy. Color Doppler US does not improve the diagnostic accuracy of US estimates of AFV.
