Abstract
Background Isolated oligohydramnios, without any known fetal/maternal abnormality, may be associated with insufficient oral intake (such as water, glucose, and rehydration therapy). Therefore, the present study was conducted to assess the improvement following maternal hydration. Method A total of 50 cases of isolated oligohydramnios (other high-risk pregnancy conditions not present) were included in the study (25 in each group). Patients were encouraged for an additional 2 liters of oral rehydration solution intake daily along with regular diet. The fluid intake was unsupervised in the home group and supervised in the hospital group. Serial amniotic fluid index (AFI) measurements and fetal monitoring were performed. Birth weight and APGAR scores were recorded, and data were analyzed. Results The two groups were comparable in terms of demographics and baseline laboratory findings. AFI significantly improved in the hospital group compared to the home group (p-value: <0.001). Birth weight, placental weight, and APGAR scores were also significantly better in the hospital group than in the home group. Conclusion Maternal oral hydration therapy improves the amniotic fluid volume and subsequently improves the perinatal outcome. Due to poor compliance with home-based treatment, institution of supervised hydration therapy is recommended.

Abstract
Aim This article determines the association and diagnostic effectiveness of abnormal Doppler and abnormal amniotic fluid volume (AFV) in the third trimester of pregnancy with preterm births. Methods The third trimester screening protocol of the Samrakshan program of the Indian Radiological and Imaging Association utilizes trimester-specific fetal Doppler studies and ultrasound assessments, estimation of the risk for preterm preeclampsia (PE), assessment of the fetal environment, growth, and structure, and staging of fetal growth restriction. A multivariate logistic regression model was used to explore associations of abnormal Doppler and AFV with preterm birth. The diagnostic effectiveness of Doppler and amniotic fluid measurements for preterm births was assessed. Results One hundred and sixty-one (25.6%) of the 630 women had a preterm birth before 37 gestational weeks. Eighty (21.1%) of the 379 women with normal AFV and normal fetal Doppler studies in the third trimester had a preterm birth. The proportion of preterm birth declined from 35.14% in 2019 to 19.53% in 2022 (chi-square test p = 0.009). Preterm birth was associated with preterm PE (adjusted odds ratio: 3.66, 95% confidence interval: 1.42, 9.44) in a multivariate logistic regression model. Both abnormal fetal Doppler and AFV did not have a good discriminatory ability for preterm births. Conclusion Integration of fetal Doppler studies helped reduce the preterm birth rate by providing an objective measure of fetal well-being, contrary to a common belief that the use of color Doppler in the third trimester may result in iatrogenic increased preterm birth. Preterm births are associated with preterm PE and early identification of high-risk women and early initiation of low-dose aspirin may have an added benefit on preterm birth rates.

Abstract
Amniotic fluid volumes are tightly regulated, and amniotic fluid derangement can indicate maternal complications or fetal abnormalities. Ultrasound estimate of amniotic fluid provides a tool to evaluate the maternal-fetal-placental interface in real-time. Oligohydramnios and polyhydramnios are associated with adverse maternal and neonatal outcomes. Oligohydramnios is associated with adverse maternal and neonatal outcomes including cesarean delivery, operative vaginal delivery, induction of labor, postpartum hemorrhage, small for gestational age neonate, intrauterine demise, neonatal death, NICU admission, and APGAR less than 7 at. 5 minutes of life Polyhydramnios is associated with adverse outcomes including cesarean delivery, induction of labor, placental abruption, shoulder dystocia, cord prolapse, postpartum hemorrhage, intrauterine fetal demise, NICU admission, neonatal death, APGAR less than 7 at 5 minutes of life, large for gestational age neonate, and respiratory distress syndrome. Therefore, Amniotic fluid should be evaluated when maternal or fetal well-being is in question.

Abstract
BACKGROUND AND AIM The evidence on isolated oligohydramnios (IO) patients and their postnatal outcomes are inconsistent. Recent research has clarified the connection between that IO and negative outcomes in the postnatal period. Our goal was to analyze the correlation between Doppler measurements and postnatal outcomes in oligohydramnios patients, with a focus on the cerebroplacental ratio (CPR). METHODOLOGY A cohort study was conducted in the Radiology Department of Khan Research Laboratories (KRL) Hospital from October 2021 to July 2022. One hundred women were chosen as the sample size. For this study, we used the Raosoft sample size calculator with a 95% confidence interval and a 5% margin of error. Both the middle cerebral artery and the umbilical artery were imaged using ultrasound, and the systolic-to-diastolic ratio and peak systolic velocity are recorded. Pulsatility index (PI) and resistive index (RI) were also calculated. If the amniotic fluid index (AFI) is less than 5 cm, the condition is known as oligohydramnios. The newborn's APGAR score was taken immediately after birth as well as after 5 minutes. RESULTS We have determined that, on average, mothers are 35.45 weeks/248.15 days pregnant. When compared to the reference standard, CPR diagnostic features showed a sensitivity of 92% and a specificity of 77.27. Overall diagnostic accuracy is predicted to be 93.0%, with a 93.50% positive prognosis and a 73.91% negative prognosis. The effect size for the change in APGAR scores before and after the test was -2.38 1.03, with a 95% confidence interval of -2.58 to -2.17 and a significance level of 0.00. CONCLUSION This study concludes that CPR is an effective screening tool and that it can be used to predict postnatal outcomes in patients with oligohydramnios. Clinical prediction rules were found to be a more effective screening tool, with a sensitivity of 92%, a specificity of 77.27%, and a diagnostic accuracy of 92.3%.

Abstract
OBJECTIVE The objective of this article was to evaluate the outcome of transabdominal amnioinfusion in pregnant patients with oligohydramnios. METHOD This is a prospective observational study involving 80 cases of oligohydramnios treated with transabdominal amnioinfusion guided by ultrasound, in the period between 2011 and 2016. The patients were treated in two centers; however, all the procedures were performed by the same operator. RESULTS The mean gestational age at the first treatment was 24 weeks. Some patients received more than one amnioinfusion. The mean interval between the first infusion and delivery was 31 d. Perinatal and neonatal mortalities were 45% and 35%, respectively. There were five cases of chorioamnioitis and in majority of the cases; the final diagnosis was made after amnioinfusion. CONCLUSION The procedure has been proven to be very safe. The result showed a high perinatal mortality which was not surprising, as these pregnancies were complicated by a major fetal malformation. Significantly, this study showed that the diagnosis accuracy of the concomitant congenital fetal malformation was significantly improved. The diagnosis accuracy had a major impact on the management of patients, especially the mode of delivery.

Abstract
BACKGROUND Currently, pregnant women are screened using ultrasound to perform gestational aging, typically at around 12 weeks' gestation, and around the middle of pregnancy. Ultrasound scans thereafter are performed for clinical indications only. OBJECTIVES We sought to assess the case for offering universal late pregnancy ultrasound to all nulliparous women in the UK. The main questions addressed were the diagnostic effectiveness of universal late pregnancy ultrasound to predict adverse outcomes and the cost-effectiveness of either implementing universal ultrasound or conducting further research in this area. DESIGN We performed diagnostic test accuracy reviews of five ultrasonic measurements in late pregnancy. We conducted cost-effectiveness and value-of-information analyses of screening for fetal presentation, screening for small for gestational age fetuses and screening for large for gestational age fetuses. Finally, we conducted a survey and a focus group to determine the willingness of women to participate in a future randomised controlled trial. DATA SOURCES We searched MEDLINE, EMBASE and the Cochrane Library from inception to June 2019. REVIEW METHODS The protocol for the review was designed a priori and registered. Eligible studies were identified using keywords, with no restrictions for language or location. The risk of bias in studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Health economic modelling employed a decision tree analysed via Monte Carlo simulation. Health outcomes were from the fetal perspective and presented as quality-adjusted life-years. Costs were from the perspective of the public sector, defined as NHS England, and the costs of special educational needs. All costs and quality-adjusted life-years were discounted by 3.5% per annum and the reference case time horizon was 20 years. RESULTS Umbilical artery Doppler flow velocimetry, cerebroplacental ratio, severe oligohydramnios and borderline oligohydramnios were all either non-predictive or weakly predictive of the risk of neonatal morbidity (summary positive likelihood ratios between 1 and 2) and were all weakly predictive of the risk of delivering a small for gestational age infant (summary positive likelihood ratios between 2 and 4). Suspicion of fetal macrosomia is strongly predictive of the risk of delivering a large infant, but it is only weakly, albeit statistically significantly, predictive of the risk of shoulder dystocia. Very few studies blinded the result of the ultrasound scan and most studies were rated as being at a high risk of bias as a result of treatment paradox, ascertainment bias or iatrogenic harm. Health economic analysis indicated that universal ultrasound for fetal presentation only may be both clinically and economically justified on the basis of existing evidence. Universal ultrasound including fetal biometry was of borderline cost-effectiveness and was sensitive to assumptions. Value-of-information analysis indicated that the parameter that had the largest impact on decision uncertainty was the net difference in cost between an induced delivery and expectant management. LIMITATIONS The primary literature on the diagnostic effectiveness of ultrasound in late pregnancy is weak. Value-of-information analysis may have underestimated the uncertainty in the literature as it was focused on the internal validity of parameters, which is quantified, whereas the greatest uncertainty may be in the external validity to the research question, which is unquantified. CONCLUSIONS Universal screening for presentation at term may be justified on the basis of current knowledge. The current literature does not support universal ultrasonic screening for fetal growth disorders. FUTURE WORK We describe proof-of-principle randomised controlled trials that could better inform the case for screening using ultrasound in late pregnancy.

Abstract
PURPOSE Intraamniotic infection, categorized into isolated maternal fever, suspected intraamniotic infection (SII), and confirmed intraamniotic infection, is associated with neonatal morbidity. However, there is paucity of data regarding the association between intraamniotic infection duration and neonatal outcomes among term singleton vaginal deliveries. We aimed to study the risk factors for adverse neonatal outcome among vaginal deliveries complicated by SII. METHODS A retrospective observational study conducted at a tertiary medical center. All consecutive singleton term deliveries with SII were included between 2011 and 2019. Maternal and obstetrical characteristics were evaluated to identify risk factors for adverse neonatal outcome. Correlation between SII duration and neonatal adverse outcome was analyzed. RESULTS Overall, 882 were analyzed. Most women (85.4%) were primiparous. Median gestation age at delivery was 40 2/7 weeks. Median time from SII to delivery was 170 min. Adverse neonatal outcomes occurred in 113 (12.8%) of deliveries. Duration of SII was not associated with adverse neonatal outcome. Analysis for determinants of adverse neonatal outcome revealed that oligohydramnios was more common in pregnancies with adverse neonatal outcome (7/113 (6.2%) vs. 41 (5.4%) OR [95% CI] 2.47 (1.02-5.98), p = 0.03). Duration of second stage of labor was longer in the adverse outcome group (median 179 min vs. 126 min, p = 0.008). Prolonged second stage was more common in the adverse outcome group (60 (53.1%) vs. 273 (35.5%) OR [95% CI] 2.05 (1.38-3.06), p < 0.001). On logistic regression analysis, prolonged second stage was the only modifiable factor independently associated with adverse neonatal outcome [adjusted OR 2.09 (1.37-3.2), p = 0.001]. Other variables tested did not differ between groups. Only phototherapy and base excess ≥ 12 mmol/L were significantly associated with the duration of second stage of labor; for each additional hour of the second stage, the OR for the former increased by 0.34 (p = 0.008), and for the latter by 0.69 (p = 0.007). CONCLUSION Duration of suspected intraamniotic infection was not associated with increased neonatal morbidity among women delivering vaginally at term. Prolonged second stage was a strong independent predictor of an adverse neonatal outcome among fetuses exposed to intraamniotic infection.

Abstract
Objective: To evaluate the maternal and perinatal outcomes of labor induction in women at term with oligohydramnios.Methods: A retrospective cohort of women with a singleton pregnancy, who had oligohydramnios at or beyond term (37-42 weeks) and underwent induction of labor for oligohydramnios were studied. Antenatally diagnosed fetal anomalies and intrauterine fetal demise were excluded. The women were categorized into two groups: 1) women with isolated oligohydramnios (n = 166) and 2) women with oligohydramnios associated with other maternal or fetal complications (n = 43). Maternal and perinatal outcomes were collected from the records of all deliveries, data compiled, and appropriate statistical tests were applied.Results: The study included 209 women with mean gestational age of 38.76 ± 1.00 weeks and mean induction-delivery interval of 17.45 ± 8.70 hours (16.98 hours in group 1 versus 19.23 hours in group 2). Most (75%) women delivered vaginally. Only one of the neonates had an Apgar score of less than 7 at 5 min. Average neonatal ICU length of stay was 5.52 days (5.27 days in group 1 versus 6.17 days in group 2). Among all the maternal and neonatal outcomes studied, only the mean birth weights among the two groups was found to be statistically significant (p = 0.0017).Conclusions: Women with isolated oligohydramnios and their neonates were not found to suffer any additional harm due to labor induction at term than women who had oligohydramnios associated with other complications.

Abstract
Oligohydramnios is associated with increased maternal and foetal morbidities. However, some of the recent studies have shown no adverse effect of isolated oligohydramnios on perinatal outcome and recommends continuation of pregnancy. Pregnancies between 18-28 weeks with isolated Oligohydramnios were included. History and physical examination was recorded in a pre-designed proforma. All the cases received care as per the protocol. A total of seven patients were recruited of which one was a twin pregnancy with Oligohydramnios in both sacs. The mean age at presentation was 30 years. Three patients went into spontaneous explusion at an average gestational age of 22-24 weeks. One patient with twins delivered vaginally at 32 weeks. Rest were delivered by caesarean section between 34-35 weeks (indication in majority of the cases was foetal distress and cord compression). None of the babies suffered any complication and were discharged in good condition. Isolated oligohydramnios during second trimester does not increase adverse perinatal outcome significantly (but increases the caesarean section rate) and therefore, should not be an indication for termination of pregnancy.
