“…Interestingly, birth weights were significantly less in infants with oligohydramnios than in those with AFI values > 5 cm. The proportion of low birthweight infants (< 2500 g) was significantly increased in the presence of oligohydramnios, findings which have also been confirmed by other authors 67,71,81 . A significantly higher incidence of congenital syndromes was diagnosed in the oligohydramnios group.…”

“…These authors concluded that in patients < 41 weeks' gestation with normal AFI values, a repeat AFI assessment is not necessary for 7 days. In contrast, due to concerns of uteroplacental insufficiency in post-term patients and the potential relatively rapid decrease of amniotic fluid volume that may occur in this clinical condition, twiceweekly amniotic fluid volume assessments are uniformly practiced 12,[70][71][72][73][74] . Nevertheless, while induction of labor of post-term patients with oligohydramnios (AFI ≤ 5 cm or no vertical pocket > 2 cm) is considered standard care, adherence to this practice clearly results in subsequent increases in labor complications and the incidence of operative delivery potentially without significantly improving outcome [75][76][77] .…”

“…Since long oligohydramniosn has long been correlated with adverse perinatal outcome, such as increased risk of intrauterine growth restriction 10,11 congenital abnormalities, postdates pregnancy 12,13 meconium passage 14 abnormal fetal heart rate patterns, and lower Apgar scores. 15 The study results analysis demonstrate that oligohydramnios is associated with increased chances of induction of labor (41% Vs 22%), non reassuring fetal heart rate(4.7% Vs 2.8%), decelerations of fetal heart rate (48% Vs 38.8%), caesarean delivery (32% Vs 23%), Apgar score < 6 at 1 min (8% Vs 1.1%), Apgar score < 7 at 5 min (6% Vs 0.56%), neonatal resuscitation (3.4% Vs 0.84%) and neonatal ICU admission (7% Vs 1.7%).…”

Objective: To determine the perinatal outcome in pregnancies complicated by isolated oligohydramnios at term. Patients and Methods: During this study 500 patients with singleton pregnancy were selected and Amniotic Fluid Index (AFI) was evaluated within 4 days of delivery in these patients with technique of Phelan et al. All selected outcome variables of these pregnancies were recorded on printed proformas. On the bases of AFI measurements patients were divided in two groups. Those who have AFI > 50 mm and < 50 mm. The significance of difference or comparison of means was measured by Chai square test (by Yats corrections). Perinatal outcomes in pregnancies with oligohydramnios were compared with those with normal amniotic fluid volume. Results:The selected outcomes showed significant variations in both groups. The statistical significance was present between advanced gestational age, presence of meconium, deceleration of fetal heart rate and chances of caesarean delivery. There were increased chances of induction of labor (41% Vs 22%) and caesarean delivery (32% Vs 23%) in oligohydramnios group. Conclusion:Oligohydramnios is associated with an increased risk of caesarean delivery for fetal distress and perinatal morbidity.

BACKGROUNDAmniotic fluid volume significantly affects the perinatal outcome, hence necessitates its measurement. Many methods are practised worldwide with every method having both advantage and limitations. Sonographic measurements help in assessing amniotic fluid volume antenatally and in intrapartum period as it is non-invasive and easy to use. Also, it is comparable with invasive methods. MATERIALS AND METHODSStudy was conducted in Mahatma Gandhi Memorial Government Hospital, attached to KAP Viswanatham Government Medical College, Trichy. The study period was from August 2012 to April 2014. Samples were 50 in group A and 50 in group B. Group A-Antenatal women admitted with borderline AFI 5 to 8 cm with singleton pregnancy who have completed 37 weeks with intact membrane. Group B-Antenatal women with Normal AFI 8 to 24 cm admitted as inpatients. RESULTSIn this study, 17 patients were below 20 years; 78 patients were between 21 to 30 years; and 5 patients were above 30 years. In this study out of 50 patients, 6, 16, 13 and 15 belonged to Gestational age of 37, 38, 39 and 40 weeks respectively and 6, 12, 17 and 15 patients belong to 37, 38, 39 and 40 weeks of gestation respectively. The mode of delivery in this study showed that 52 patients delivered by caesarean section (LSCS) and 48 patients by Labour natural which had P value of 0.423 (p >0.05) which is insignificant. The nature of amniotic fluid among group A was clear in 36 patients and meconium stained in 14 patients. Among group B, 78 patients had clear amniotic fluid and 22 had meconium-stained amniotic fluid. This is insignificant as the P value is 0.148 (p>0.05) which signifies that the nature of amniotic fluid does not depend solely on AFI level but also on other factors too. Implies that the mode of delivery doesn't significantly differ with amniotic fluid index. CONCLUSIONAssessing amniotic fluid antenatally and intrapartum foetal surveillance in means of Amniotic fluid index and Non-stress test helps in monitoring of foetus throughout antenatal period and also during labour. Identifying the way the foetus behaves during labour in borderline amniotic fluid index patients by means of foetal heart rate tracings (NST) helps in picking up foetal distress earlier and leads to deliver a neonate with good Apgar reducing the perinatal adverse outcome.
