Objective: To characterize ultrasound images of placenta and amniotic fluid in cases of singleton pregnancies beyond term predictions, and also explore the relationship between placenta, amniotic fluid and labor transfer status, postpartum child status. Image properties of prenatal placenta and amniotic fluid are immediately examined with ultrasound in 267 cases of postterm pregnancy beyond prediction at Obstetric Department, Hue Central Hospital. Results: In postterm pregnancy, placenta thickness decreases gradually according to gestational age. Oligohydramnios is 30.3%. There is a correlation between amniotic fluid index and birth method with r = 0.41. Sensitivity is 89.15%. Specificity is 48.55%. There is also a correlation between amniotic fluid echogenicity and method of birth: r = 0.478. Sensitivity is 97.67%. Specificity is 42.75%. Amniotic fluid index and baby Clifford's syndrome are also relevant, with r=0.466. Sensitivity is 83.78%. Specificity is 78.26%. Conclusions: Ultrasound scanning of amniotic fluid properties should be noted in the case of postterm pregnancy.

Background: Oligohydramnios refers to amniotic fluid volume that is less than expected for gestational age. We aimed to assess the perinatal outcomes in pregnancies with oligohydramnios.Methods: The prospective study was conducted in the Department of Obstetrics and Gynecology, Pravara Medical College, Loni in which 200 consecutive singleton pregnancies delivered vaginally, with intact membranes were included. Amniotic fluid index was determined using the Phelan’s technique at the time of admission and women were diagnosed with oligohydramnios if AFI was five or less, which formed the first group and the rest of mother formed the second group. Perinatal outcomes were noted in the proforma as well.Results: Of the 200 mothers included in the study, 38 had AFI ≤ 5. Baseline characteristics was similar in both the groups. Most common antenatal risk factors studies were pregnancy induced hypertension (29% vs 12%; p value <0.05), intrauterine growth restriction (34% vs 10%; p value <0.001) and severe anemia (21% vs 9%; p value <0.05). Proportion of pregnancies needing induction of labor and birth weight less than 2.5 kgs were significantly higher among mothers with oligohydramnios.Conclusions: Authors observed that induction of labor and low birth weight were significantly associated with oligohydramnios. Prospective randomized trials are needed to establish whether early induction of labor in the presence of a oligohydramnios improves perinatal outcome.

Background: Amniotic fluid provides necessary fluid and growth factors for normal development of fetal lungs, cushions the umbilical cord from compression and protects the fetus. This study aims to compare the perinatal outcome between pregnancy with borderline and normal Amniotic Fluid Index that provide greatest chance for appropriate safe delivery with least maternal fetal and neonatal risk.Methods: A total of 94 singleton full term pregnant women were included in the study-at Kathmandu Model Hospital from February to August 2020. Forty Seven women each with Amniotic Fluid Index 5-8 cm was taken as borderline oligohydramnios group and Amniotic Fluid Index 8.1-24 cm was taken as normal group. Ultrasonography was taken as the medium for measuring Amniotic Fluid Index.Results: The rate of intra-partum fetal distress, meconium-stained amniotic fluid, low birth weight and neonatal intensive care unit admission were not statistically significant between the two groups while rate of cesarean section was noted to be 76.6% in exposed groups as compared to 44.7% among women with non-exposed normal group [RR=1.71; 95%CI: 1.2-2.44 p=0.006]. Conclusions: We concluded that in cases of borderline oligohydramnios there was higher risk of operative delivery.Keywords: Adverse perinatal outcome; amniotic fluid; borderline oligohydramnios; meconium-stained amniotic fluid

Objective. Hourly fetal urine production rate (HFUPR) was studied in relation to both gestational age and the onset of spontaneous labor in normal term human pregnancies. Methods. Serial volume measurements were obtained from longitudinal ultrasound images of the fetal bladder at 1–5-minute intervals, and HFUPR was subsequently calculated. A total of 178 adequate bladder-filling cycles were recorded in 112 women, and the amniotic fluid index (AFI) was assessed. Results. HFUPR did not change significantly between 37 and 42 weeks' gestation. However, HFUPR decreased during the last 14 days prior to the onset of spontaneous labor (). No significant correlation was found between HFUPR and AFI, neither when measured at the same time nor when HFUPR and AFI were measured at various intervals in time. Conclusion. HFUPR falls before and in relation to the time of onset of labor rather than in relation to gestational age.

<b><i>Objective:</i></b> The aim of the article was to investigate the changes in intra-amniotic pressure following transabdominal amnioinfusion during pregnancy. <b><i>Design:</i></b> This retrospective study included 19 pregnant women who underwent transabdominal amnioinfusion during pregnancy to relieve umbilical cord compression and improve the intrauterine environment or to increase the accuracy of ultrasonography. <b><i>Materials and Methods:</i></b> We measured and analyzed the changes in intra-amniotic pressure, single deepest pocket, and the amniotic fluid index before and after amnioinfusion. We also determined the incidence of maternal or fetal adverse events, such as preterm premature rupture of membranes, preterm delivery, fetal death within 48 h, placental abruption, infection, hemorrhage, and peripheral organ injury. <b><i>Results:</i></b> A total of 41 amnioinfusion procedures were performed for 19 patients. The median gestational age during the procedure was 24.3 weeks. The median volume of the injected amniotic fluid was 250 mL. The median single deepest pocket and amniotic fluid index after amnioinfusion were significantly higher than those before amnioinfusion (4.0 cm vs. 2.65 cm; <i>p</i> &#x3c; 0.001 and 13.4 cm vs. 6.0 cm; <i>p</i> &#x3c; 0.001). However, the median (range) intra-amniotic pressure after amnioinfusion was not significantly different compared to that before amnioinfusion (11 mm Hg vs. 11 mm Hg; <i>p</i> = 0.134). Maternal or fetal adverse events were not observed following amnioinfusion. <b><i>Conclusion:</i></b> Intra-amniotic pressure remained unchanged following amnioinfusion. The complications associated with increased intra-amniotic pressure are not likely to develop if the amniotic fluid index and/or single deepest pocket remains within the normal range after amnioinfusion. Studies of groups with and without complications are warranted to clarify the relationship between the intra-amniotic pressure and incidence of complications.

Background: The purpose was to determine whether AFI<5 cm after preterm premature rupture of the membranes (PPROM) is associated with an increased risk of maternal and perinatal morbidity.Methods: We performed a prospective case control study of 161 singleton pregnancies complicated by preterm prelabour rupture of the membranes (PPROM) in whom AFI was assessed. Patients were categorized in two groups on the basis of amniotic fluid index- AFI<5 cm or AFI ≥ 5 cm. Categorical data were tested for significance with the χ2 and Fisher exact tests. All 2-sided p values < 0.05 were considered significant.Results: Both groups were similar with respect to selected demographics, gestational age atrupture of the membranes, gestational age at the delivery, birth weight. Both groups were similar with respect to maternal chorio-amnionitis, abruption, mode of delivery, early onset neonatal sepsis and NICU stay. Patients with AFI<5 cm demonstrated greater frequency of C/S delivery for non-reassuring fetal tests.Conclusions: There is no significant difference between obstetric outcome in AFI<5 and AFI> 5 after PPROM between 24- and 37-weeks’ gestation.
