This might be the reason for their finding of rapid fall of AFI from 34 to 35 weeks, plateauing between 37 and 39 weeks and once again slow fall at 40 weeks. Khadilkar et al. Mean change in AFI (cm) values at different intervals. We used difference in mean values of one week to the next week to evaluate the decreasing trend of amniotic fluid from 34 to 40 weeks of gestation (Table 2). A. Baschat, R. M. Viscardi, B.

Uterus was arbitrarily divided into four quadrants using linea nigra as a vertical line and a transverse line passing through umbilicus, as described by Phelan et al. Adequate fluid volume is detected by ultrasound, and the normal volume is indicated when the AFI (amniotic fluid index) is between 8 to 18 cm. At values less than 5, there is higher incidence of perinatal morbidity and mortality and many a time immediate delivery is the only way out [12, 13]. What does poly hydromonios 32 weeks and AFI of 26 suggest? The percentile curves of AFI obtained from the present study may be used to detect abnormalities of amniotic fluid for our population. Percentile curves (5th, 50th, and 95th centiles) were constructed for comparison with other studies. Amniotic fluid index (AFI) is one of the major and deciding components of fetal biophysical profile and by itself it can predict pregnancy outcome.

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. Amniotic fluid index was obtained by adding these four measurements. Women with gestational or overt diabetes mellitus, hypertensive disorders of the pregnancy, prelabour rupture of membranes, and congenital anomalies in the foetus and those who delivered before 40 completed weeks were excluded from the study. The women were medium built, the average height was of 152 to 156 cms, and prepregnancy weight was between 45 and 50 kg. Effect size is a simple measure for quantifying the difference between two groups or the same group over time, on a common scale. The AFI values differed throughout the gestation and there was a gradual decline in the values as pregnancy advanced. An AFI < 5-6 is considered as oligohydramnios. Materials and Methods. Table 4 compares our finding with that of other authors [16, 22–25]. Hence it is very important to scan the patient to note such a trend periodically during antenatal visits. Statistical analysis was done using SPSS software (Version 16, Chicago, IL). @desiexpat amniotic fluid is referee to as liquor by many.. Appreciable changes occurred in AFI values as gestation advanced by two weeks. However, a drastic reduction in its quantity may indicate underlying placental insufficiency, which has definite implications on growing fetus. Premium Questions. Background. hydromonios 32 weeks..liquor is increased with an AFI 26cms. Of the 50 patients who were recruited for the study and were between the age of 22 to 28 years, more than half (32 patients, 64%) were primigravidae and 18 (36%) were multigravidae. AFI values from 34 to 40 weeks; mean, standard deviation, and percentile values (all in centimeters). from Iran. The authors have no conflict of interests to declare. The ultimate goal of antepartum surveillance program is to improve perinatal outcome and to decrease intrauterine fetal demise besides prevention of maternal morbidity and mortality [1, 2]. Khadilkar et al. It can be seen that many cells have the values less than 1, but still the difference may be calculated statistically significant if ordinary statistical tests such as paired test were applied and hence we have used Cohen’s test which very well detects the magnitude of change.
