Correlation Between Amniotic Fluid Index and Estimated Fetal Weight in Third Trimester of Pregnancy

This study was conducted to find out the correlation between amniotic fluid index (AFI) & estimated fetal weight (EFW) in third trimester of pregnancy. This cross sectional study was carried out on 105 women with normal singleton pregnancies at third trimester. The pregnant women were subdivided into three groups. The AFI & EFW were evaluated according to gestational age groups & fetal sex. Significant positive correlations were found between estimated fetal weight and amniotic fluid index in female fetuses of all three groups. In male fetuses, there was a significant positive correlation between AFI & EFW in group III (38 to 40 weeks), but insignificant correlation in other two groups. No study was conducted previously in Bangladesh to see the relationship between AFI & EFW. This study shows that amniotic fluid volume can be evaluated more precisely during third trimester of pregnancy by taking estimated fetal weight into consideration in third trimester of pregnancy.

ABSTRACT Objective To ascertain that acrania can lead to anencephaly Materials and methods We commenced a cross-sectional study for a period of 41 months from 2013 to 2017. During routine ultrasound examination, we observed multiple cases of acrania in second trimester and third trimester. We followed 26 cases who failed to terminate their pregnancies and visited for reexamination. Changes in the brain matter, amniotic fluid volume, and echogenicity of the acrania fetuses were recorded and compared with the previous examination. Development of anencephaly was correlated with maternal age and advancement of gestational age. All the patients were examined transabdominally according to the American Institute of Ultrasound in Medicine (AIUM) guidelines for obstetrical ultrasound. Data were collected from the previous report and recent examination, by evaluating data with the help of IBM Statistical Package for the Social Sciences (SPSS) version 24 package, and the results were summarized. Results Pregnant women with diagnosed acrania fetus visited second time with a lapse of more than 4 weeks and were enrolled with mean age 25.73 ± 8.80. We observed 4 (15.4%) acrania patients developed into anencephaly. Development of anencephaly was observed to be correlated with the advancement of gestational age. It was observed that acrania is more common in below 20 and above 30 age groups. Haziness of amniotic fluid is also observed to be related with acrania. Conclusion Anencephaly could be caused by multiple factors but acrania can lead to anencephaly with continuous exposure of brain matter and meninges to mechanical trauma and chemical activities of the amniotic fluid. Clinical significance To test the hypothesis of acrania to anencephaly and make a roadmap for upcoming researches on association of acrania with physical, environmental, and genetical factors.

Record Section

Introductions: Sonographic assessment of four quadrant measurement of amniotic fluid index (AFI) is an integral part of antenatal evaluation of pregnancies, especially in the third trimester. Decreased (oligohydramnios, AFI 0-9.9 cm) or increased (polyhydramnios >25 cm) increases the risk of intrauterine growth retardation, birth asphyxia and induction or operative interference. The aim of this study was to analyse abnormal liquor volume and mode of delivery. Methods: This retrospective cross-sectional study analysed the cases of abnormal liquor volume in term pregnancies during 2013-2016 at Patan Hospital. Patient's files were traced from medical record section. We analysed the abnormal liquor volume based on amniotic fluid index (AFI) and the mode of deliveries. Results: Among 15,272 term pregnancies scanned, 130 had abnormal AFI, 128 oligohydramnios and 2 polyhydramnios. Out of 128 oligohydramnios, 40 (30.8%) were severe, 54 (41.5%) moderate and 34 (26.2%) mild. Two cases had polyhydramnios. The emergency lower uterine segment caesarean sections (emLSCS) were performed in 99 (76.1%) oligohydramnios. Conclusions: This study suggests that oligohydramnios measured by AFI at term pregnancy required more emLSCS.

Estimated Fetal Weight

Introduction: Fetal weight (FW) estimation in late pregnancy is an important guide in obstetric care. Amniotic fluid protects the fetus against traumatic and infective insults. There possibly exists a relationship between FW and amniotic fluid index (AFI) that can be estimated by ultrasonography. Materials and Methods: Two hundred and fifty-eight low-risk pregnancies were prospectively studied by means of ultrasound over a 12-month period. FW was estimated using a combination of fetal parameters; bi-parietal diameter, fetal trunk cross sectional area, and femur length. AFI was assessed using the 4-quadrant method. Spearman's correlation was used to test possible relationship between amniotic fluid indices and estimated FW pairs. The level of statistical significance was set at P ≤ 0.05. Results: The mean AF1 and estimated fetal weight (EFW) pairs were as follows: at 27-29 weeks the values were 172.1 mm and 1,250.2 g; at 30-32 weeks AF1 and EFW values were 170.3 mm and 1,648.0 g; at 33-35 weeks values were 162.3 mm and 2,273.5 g; at 36-38 weeks values were 144.09 mm and 2,906.1 g; at 39-40 weeks AF1 and EFW values were 125.0 mm and 3,222.6 g. Overall, there was no statistically significant relationship between AFI and EFW (P > 0.05; r = 0.241). Conclusion: While FW calculations and amniotic index showed variations in value in late pregnancy, there does not appear to be a linear relationship between ultrasound estimate of FW and amniotic index. The implication of this is that fetal size need not be taken into cognizance when alterations in amniotic fluid values are noted.

AbstractThe increased risk of caesarean section after induced labour is well documented. Rate of induction of labour has doubled in the past decade from 10 to 20%. Low Amniotic Fluid Index (AFI) as an isolated finding leads to increased obstetrical interventions but without any improvement in outcome.Objectives: To determine the frequency of caesarean section due to failed induction in pregnancies at term with borderline AFI.Patients and Methods: This cross-sectional study was conducted at Department of Obstetrics and Gynaecology, Unit-III, SIMS/Services Hospital, Lahore. The duration of study was one year from January, 2015 to December, 2015. A total of 150 patients were included in this study. AFI was measured by recent obstetric ultrasound. All patients with borderline AFI (5 – 8 cm) were included in the study. They were induced by glandin E2 gel. If induction of patients failed with two doses of glandin E2 gel, given vaginally 6 hours apart, patients were considered for cesarean section. The outcome measure was rate of caesarean section due to failed induction. All data were analyzed by SPSS version 20.Results: Mean age of the patients was 30.34 ± 6.68 years. Mean gestational age was noted 38.34 ± 1.05 weeks. Out of 150 patients, 103 (68.7%) were para 1 – 3 and 47 patients (31.3%) were para 4 – 6. Caesarean section due to failed induction with borderline AFI was performed in 27 patients (18.0%). Stratification with regard to age, gestational age and parity was carried out and was found significant only for gestational age being > 39 weeks.Conclusion: It is concluded that failed induction of labour at term in women with borderline AFI is not associated with increased risk of caesarean delivery.
