How accurate is ultrasound in dating pregnancy

It reflects both mother and fetal status [ 12 ]. Enrolled subjects were recruited and allocated into two groups. The study showed AFI rising from 20 weeks to 28 weeks and thereafter, demonstrated steady but gradual decline as pregnancy advances. Amniotic fluid index is reported to vary not only with gestation [ 12 ] but also with population [ 3 ]. For mothers at 22 weeks:

The importance of the amniotic fluid volume as an indicator of fetal well-being has been extensively documented [ 5 - 11 ]. Keywords Amniotic fluid index; Pregnancy; Obstetric care ; Ultrasound scan Introduction Ultrasound assessment of amniotic fluid has significant implication in obstetric care and it has become an integral and important component of pregnancy assessment [ 1 , 2 ]. The participants ranged from those that were Para zero to Six. Materials and Methods This was a comparative longitudinal prospective assessment of amniotic fluid index in healthy pregnant women with singleton pregnancies. Included were all pregnant women who had given consent and with; singleton cephalic presenting pregnancy, reliable dating of gestational age regular menstrual cycle , certain first day of the last normal menstrual period and no form of contraception in the last 6 months of conception , confirmed last menstrual period by ultrasound scan done before 20 weeks of gestation and dating in agreement to within 7 days. The technical bulletin on obstetric ultrasonography from The American College of Obstetrician and Gynecology states that amniotic fluid index is a more accurate and reproducible method of determining abnormalities in amniotic fluid volume than are other techniques [ 26 ]. However, as AFI values may be affected by the difference of race and environment, caution is exercised when previously established AFI values are applied to pregnant women with different racial and environmental backgrounds [ 1 ]. Table 1 describes the descriptive data for AFI. Amniotic fluid index is reported to vary not only with gestation [ 12 ] but also with population [ 3 ]. It also minimized loss to follow up and maximized the observations. It reflects both mother and fetal status [ 12 ]. The other group was examined at 22, 26, 30, 34, 38 and 41 weeks 3 days. June 22, ; Published date: Subjects who did not meet above inclusion criteria or decline consent to participate were excluded. The data were normally distributed at each gestation. The maintenance of appropriate amniotic fluid volume for gestational age remains an important and integral component for fetal well-being determination [ 13 ].

J Women's Health Care 6: This was for the purpose of obtaining a reading every two weeks even though patients were being seen every 4 weeks. It can be either a subjective assessment visualization without ultrasonic measurements , a semi quantitative estimation using the single deepest pocket otherwise equivalent to maximum vertical pocket depth, amniotic fluid index [ 14 , 20 , 21 ] 2 diameter pocket [ 22 ] or 3 dimensional measurements [ 23 ]. The study showed AFI rising from 20 weeks to 28 weeks and thereafter, demonstrated steady but gradual decline as pregnancy advances. The results were stratified by week of gestation. It is therefore necessary that the normal values of the amniotic fluid across the gestational age be established [ 1 ].
