ABSTRACT Objectives The study was undertaken to determine the efficacy of routine estimation of amniotic fluid volume using the amniotic fluid index (AFI) as a means of predicting an adverse perinatal outcome in low-risk pregnancies. Materials and methods Five hundred and three singleton lowrisk pregnancies with cephalic presentation between 37 and 40 weeks and 6 days of gestation with intact or ruptured membranes had AFI estimations within 36 hours of delivery. Results The frequency of nonreassuring fetal heart patterns and perinatal outcomes among patients with oligohydramnios (<5 cm), borderline oligohydramnios (5 to 8 cm) and normal (>8 cm) liquor were compared and not found to be different. Cesarean section for nonreassuring fetal status was also similar in the three groups. Conclusion This study suggests that AFI estimation during labor in low-risk pregnancies does not predict adverse perinatal outcomes. Further studies are needed to verify this impression.

Background: Fetal surveillance even in normal or low risk pregnancy is essential to ensure safe parturition with minimum intervention. Cardiotocography (CTG) and clinical estimation of amniotic fluid volume (AFV) measured as amniotic fluid index (AFI) are two tests that are easily available in the labor room and can be used to identify fetal well-being. Our study aimed to evaluate role of admission cardiotocography (CTG) and amniotic fluid index (AFI) on perinatal outcome in low risk pregnancy at term.Methods: The study was conducted as a prospective observational study. All low risk pregnant women at term admitted to the labor ward in early or established labour between September 2018 and August 2020 were included in the study. They underwent admission CTG and AFI assessment using ultrasonography. All parameters including CTG changes, mode of delivery, AFI, presence of meconium, APGAR score at 1 and 5 mins, need for admission in neonatal ICU and perinatal mortality were recorded. Quantitative data was compared using chi square test.Results: A total of 180 patients were included in the study. Majority of the women belonged to the age group of 30-35 years. Abnormal CTG showing fetal distress was seen in 105 (58.33%) cases. Non-reactive CTG was significantly associated with meconium stained liqour, requirement for LSCS, still birth, fetal distress, APGAR <7 at 1 and 5min and NICU admission (p<0.001). The association of low AFI with non-reactive CTG had statistically significant impact on perinatal outcomes like low birth weight, requirement for LSCS, fetal distress, APGAR <7 at 1 and 5 mins and NICU admissions.Conclusions: Admission CTG is a simple non-invasive test that can serve as a screening tool in low risk obstetric population to detect fetal distress already present or likely to develop and prevent unnecessary delay in intervention. Thus, it may help in preventing fetal morbidity and mortality.

Background: Amniotic fluid index (AFI) is kind of an estimate of the amount of amniotic fluid. It is an index for the fetal well-being. The aim was to study fetal and maternal out come in cases of low AFI and normal AFI.Methods: This was a case control prospective comparative study performed on 200 randomly selected low risk pregnant patients at term (37-40 weeks of gestation) admitted in Obstetrics and Gynaecology Department. 100 patients with AFI <5 cm (cases) and 100 patients with AFI 8-20 cm (control).Results: Increased number of LSCS in cases that is 35 while only 10 in control and almost equal incidences of MSL and FD in both the groups, while in cases 17 women were planned for elective LSCS for various indications in expectation of better fetal outcome.  There was significant low APGAR score in babies of cases, but clinically we refute this. In present study almost double the no. of babies in cases was IUGR or FGR. Significant association between low AFI and congenital anomalies in babies. Most of the anomalies were of urinary tract system.Conclusions: An AFI ≤5 cm detected at term that was at or after 37 completed weeks of gestation in a low risk pregnancy was an indicator of poor perinatal outcome. Oligohydramnios was being detected more frequently now-a-days due to ready availability of ultrasonography these days.

Background: To evaluate whether oligohydramnios (AFI≤5) has any significance in the outcome of low risk pregnancies. Normal amniotic fluid index in pregnancy is one of the indicators of fetal well-being.  In a term pregnancy, oligohydramnios, a condition associated with AFI≤5, could be a sign of placental insufficiency. An association of low AFI with complications like pregnancy induced hypertension, consistently leads to poor fetal outcome. A need to deliver the fetus by cesarean section often arises. Occasionally one comes across a full-term pregnancy with AFI ≤5 with no known high risk factors; this could lead to increased cesarean section rates. Thus, it becomes necessary to evaluate if AFI ≤5 in the absence of other risk factors has any significance on obstetric outcome.Methods: Prospective case controlled study was done. Fifty women with term pregnancies and (AFI≤5) cm not associated with any other high risk factors were enrolled for the study. They were matched with fifty controls with normal AFI.Results: Except for a slight increase in variable deceleration in the study group, no differences were noted with fetal heart rate recordings in NST.  Decreased AFI was not associated with increased cesarean section rates, instrumental deliveries or meconium stained amniotic fluid. Severe asphyxia, NICU admission or perinatal mortality was not noted in either group.Conclusions: When a low risk pregnancy is associated with Oligohydramnios (AFI≤5), it does not have any deleterious effect on labor outcome or perinatal outcome.

ABSTRACT Objective To assess the role of routine third trimester ultrasound in low-risk pregnancy on antenatal interventions and perinatal outcome. Design Randomized controlled study. Setting KLES Dr Prabhakar Kore Hospital and Medical Research Center, Belgaum. Subjects A total of 290 low-risk pregnant women between 34 and 37 weeks attending antenatal clinic and fulfilling inclusion criteria were allotted using computer-generated randomization numbers into study and control groups. Intervention In study group, third trimester ultrasound was performed to assess fetal growth, amniotic fluid index (AFI), malpresentations, and late onset fetal anomalies. In control group, no routine ultrasound was performed, unless indicated by clinical suspicion during subsequent visits. High-risk fetuses identified were managed as per the standard protocol. All women were followed to assess antenatal interventions, intrapartum events and perinatal outcome. Results Detection of high-risk fetuses antenatally in study and control groups was 17.25 and 2.07% respectively. This difference was statistically significant (p = —0.0001). Rates of antenatal interventions among study and control were 24.8 and 4.44% respectively. Prevalence of small for gestational age (SGA) fetuses among study and control was 6.9 vs 11.03% respectively. This difference was not statistically significant (p = —0.253). There was no statistical difference in adverse intrapartum events, cesarean section rate for nonreassuring cardiotocography (CTG), low Apgar score and neonatal intensive care unit (NICU) admissions among study and controls. Conclusion Routine third trimester ultrasound is a logical solution for detection of high-risk fetuses in low-risk pregnancies which would otherwise be missed by clinical examination. However, this leads to an increase in antenatal interventions without significantly influencing the perinatal outcome. How to cite this article Revankar KG, Dhumale H, Pujar Y.

Background: Oligohydramnios is a frequent complication of pregnancy that is associated with increased perinatal morbidity and mortality. Once diagnosed; oligohydramnios should further lead to intensive fetal surveillance including ultrasound evaluation. The aim of the study was to determine obstetric outcome in term low risk pregnancy with AFI less than or equal to 5 and to assess whether antepartum oligohydramnios is associated with adverse perinatal outcome.Methods: 200 patients in third trimester in the hospital with evidence of oligohydramnios (AFI less than or equal to 5) were selected after satisfying inclusion and exclusion criteria and studied prospectively. Observations regarding the outcome of labour in form of maternal and perinatal parameters including AFI value, CTG features, mode of delivery, LSCS rate, meconium stained, APGAR score, birth weight and NICU admission were made.Results: Overall perinatal outcome with respect to CTG, 128 (64%) out of 200 patients had non-reactive CTG and only 72 (36%) had reactive CTG. 128 (64%) of non-reactive CTG delivered by LSCS, 72 (36%) delivered by labour natural. Nil labour natural in the subset of AFI 1 to 2, birth weight (<2.5 kg-8% and >2.5 kg-92%), Apgar score (<7 at 1-5 mins:18%), still birth (1%), meconium (58.5%), NICU admission (6%) and perinatal mortality (2%).Conclusions: AFI measurement of less than 5 cm detected after 37 completed weeks of gestation with a low risk pregnancy is found to be an indicator of adverse pregnancy outcome with higher fetal distress, meconium stained liquor and higher caesarean section rate. AFI assessment serves as an important tool and remains as an effective screening test in predicting fetal distress in labour that requires caesarean section.
