Objective:To determine the effect of maternal (oral) hydration on amniotic fluid volume in patients with third trimester oligohydramnios. Design: Interventional study. Place and Duration of Study: Department of Obs & Gynae Unit III, Sir Ganga Ram Hospital, Lahore from May 2002 to October 2002. Patients and Methods: Twenty five women with third trimester oligohydramnios (AFI ?5.0cm) and twenty five controls with normal amniotic fluid volume (AFI 8-24 cm) were prospectively recruited for this study. Maternal urine specific gravity and amniotic fluid index were determined before and after maternal hydration by asking them to drink 2 L of water in 2-4 hours before repeat amniotic fluid index and recorded on printed proformas. Results: Hydration increased amniotic fluid volume in women with oligohydramnios (mean change in amniotic fluid index 4.3 cm, 95% confidence interval 4.02 to 5.06; P value <0.001); as well as in women with normal fluid volume (mean change in Amniotic fluid index 2.7 cm, 95% confidence interval 2.23 to 3.21; P value <0.01). However, percentage increase in mean AFI was 58.6% in the oligohydramnios group, which was significantly greater (P value <0.05) than the percentage increase of 28.4% in control group. Hydration was associated with decrease in urine specific gravity in both groups. Conclusion: Maternal (oral) hydration increases AFV in women with oligohydramnios as well as in women with normal AFV and may be beneficial in the management of oligohydramnios.

Background: The best method of estimation of amniotic fluid volume is a matter of ongoing debate. Objectives: To determine the perinatal & maternal outcomes in pregnant patients when the amniotic fluid volume was assessed by the amniotic fluid index (AFI) in comparison to the single deepest vertical pocket (SDVP). Methods: We studied abnormal Cardiotocograph, meconium stained amniotic fluid, birth weight <2.5kg, Apgar score at 5 min <7, cord blood pH <7.2 & necessity for NICU admission as perinatal outcomes. Rate of diagnosis of oligohydramnios, induction of labor for oligohydramnios & mode of delivery were observed in maternal outcomes. Results: Of the 697 pregnant patients recruited, 353 were in the AFI and 344 in the SDVP group. Perinatal outcomes were similar in both. In the AFI group, the number of women diagnosed with oligohydramnios was higher (p = 0.0333) & the rate of induction was also higher (p = 0.003378). Vaginal deliveries were more in the SDVP group. The Receiver Operating Characteristic curves showed statistically significant correlation with NICU stay, birth-weight, and mode of delivery. While an AFI of >5cm and SDVP of >1.9cm had good sensitivity in predicting babies with a birth weight of ≥ 2.5kg and avoiding NICU admissions, an AFI of > 5.8cm and an SDVP of > 1.9 cm had a sensitivity of around 80% in predicting successful vaginal deliveries. Conclusion: The SDVP method has a slight edge over the AFI in terms of lower inductions and higher vaginal deliveries with comparable perinatal outcomes.

Background & Objectives: The measurement of amniotic fluid volume (AFV) has been an important component of antenatal evaluation of fetal well being. The most commonly used methods are by amniotic fluid index technique (AFI) and single deepest pool method (SDVP). Both the methods employ ultrasound for AFV measurement. The objective of this study is to compare the usefulness of AFI and SDVP method in assessing amniotic fluid volume for predicting adverse perinatal outcome.Materials & Methods: This is a hospital based prospective comparative study. The patient whose amniotic fluid was measured by SDVP technique was study group and that by AFI was comparison group. Any case with high risk factor was excluded from the study. First case was decided by lottery and then alternately one case was kept in study group and the other in comparative group. If the women did not deliver within 1 week the measurements was retaken and the final values was used for analysis.AFI was estimated as described by Phelan and colleagues and SDVP as described by Manning. Data collection was started after the approval of Institution review board. This study was conducted at Patan Academy of Health Sciences. Duration of data collection was 3 months, Asadh –Bhadra, 2071.Results: A total of one hundred and fifty four cases which met the inclusion criteria were taken. Incidence of oligohydramnios by SDVP method was 10.4 % by SDVP technique and by AFI method it was 18.2 %. There was no statistical significant difference between the two groups in terms of rate of induction, mode of delivery, meconium staining of liquor, fetal heart rate tracings, APGAR score at 5 mins and admission to special care baby unit.Conclusion: In non-high risk pregnancy AFI technique detects slightly more number of oligohydramnios as compared to SDVP technique without apparently any difference in perinatal outcome.

Background: Oligohydramnios is the term coined for a condition where the amount of liquor amnii is less than 200 ml at term. Using an ultrasonogram, oligohydramnios can be deliberated when the vertical pocket of liquor is less than 2 cm or when amniotic fluid index (AFI) is less than 5 cm. Oligohydramnios is reported to occur in 1 to 5% of total pregnancies. It has been associated with adverse maternal and foetal outcomes.Methods: This hospital-based follow-up study was conducted among 540 pregnant women at 37 weeks attending to the Department of Obstetrics and Gynaecology for a period of 1 year from January to December 2018. All included pregnant women were subjected to routine ultrasound examination and assessment of amniotic fluid volume using Amniotic fluid index.Results: The incidence of oligohydramnios was 17.04% (n=92) among the included women and 62% (n=57) among them were primigravida. Among those women diagnosed with Oligohydramnios, the caesarean section rate was 56.5% (n=52), the common indications for LSCS being fetal distress 44. 2% (n=23) and IUGR 34.6% (n=18). The oligohydramnios pregnancies had more associated post-dated deliveries (28.3%), pregnancy induced hypertension (10.9%) and gestational diabetes (8.7%). It was also associated with higher incidence of low birth weight (27.2%), NICU admissions (32.6%), congenital anomalies (3.3%) and fetal deaths (5.4%).Conclusions: The study showed that an amniotic fluid index of less than 5 at term was associated with adverse maternal and perinatal pregnancy outcomes emphasizing the importance of amniotic fluid volume surveillance during the antenatal period.

Background: Perinatal morbidity and mortality are significantly increased when oligohydramnios is present. As the amniotic fluid volume decreases, the perinatal mortality rate increases. The incidence of major congenital anomalies with IUGR also increases as the amniotic fluid volume declines. There is a close association between declining placental function in the latter part of the third trimester and amniotic fluid volume1. Thus, post term patients are at a greater risk for development of oligohydramnios. Fetal anomalies that results in oligohydramnios classically involve the urinary tract. The most frequently mentioned renal anomalies include bilateral renal agenesis, multicystic dysplastic kidneys, bladder outlet obstruction and infantile polycystic kidneys.Methods: All antenatal patients seen in the Department of Obstetrics and Gynecology at Sri Siddhartha Medical College and Research Centre between January 2015 to January 2017, who were willing to participate in the trial study were enrolled. Ultrasound GE Voulson S8-PRO equipped with 3.5 MHz transducer was used to measure the amniotic fluid index. The AFI in each group was noted and the pregnancy outcome in each group was determined. At the time of delivery following data variables were collected and compiled.Results: There were 105 women, who were divided into three groups of 35 each. Those women with AFI<5 had more chances of emergency caesarian section, the causes were fetal distress with variable and late fetal heart decelerations. The incidence of meconium stained liquor and NICU admission were more.Conclusions: The women with AFI<5 had more chances of emergency caesarian section, the causes were fetal distress with variable and late fetal heart decelerations. Amniotic Fluid Index is a valuable screening test for detecting fetuses that may have poor perinatal outcome.

Introduction Amniotic fluid volume reduction can have serious consequences prior to 24 gestational weeks hypoplasia of fetal lungs and later in pregnancy cord compression and fetal hypoxia as well as contractions of extremities. Diagnosis of oligohydramnios is made either after a subjective estimation of amniotic fluid reduction or if the biggest amniotic fluid pocket is less than 1 cm. Amnioinfusion is a procedure during which a crystalloid solution, most often saline, is instilled into the amniotic cavity substituting amniotic fluid. To estimate the efficacy and safety of amnioinfusion using our results and literature review. Material and methods Up to 800 ml of sterile saline solution was instilled intraamniotically (10-15 ml/min) in cases where the amniotic fluid index was less than 10 and intraamniotic infection was excluded. After that, 1 g of Longaceph was given intraamniotically. Infusion was stopped immediately when 800 ml was instilled, if a subjective estimation showed that there was enough fluid or if contractions occurred. Results During a six-month period there were five amnioinfusions - four therapeutical and one diagnostic; in four cases the procedure was successful and in one preterm rupture of membranes occurred 20 hours after the procedure. The procedure was most often done in the first half of the third trimester and continuation of pregnancy in successful cases was between 4 and 5 weeks, with average fetal weight gain of about 1200 gr No complications occurred in cases where pregnancy continued. Conclusion In our preliminary study amnioinfusion led to prolongation of pregnancy in majority of cases providing better maturation of fetal lungs and higher birth weight, without any complications. Further studies are necessary to reach definite conclusions about the efficacy and safety of amnioinfusion.

ABSTRACTBackground: Abnormal amniotic fluid volume (AFV) may be the only or earliest sonographic sign of an obstetrical problem. There is no clear consensus on the best method to assess amniotic fluid adequacy. The AFI and the SDVP are the more commonly employed techniques for assessing adequacy of amniotic fluid. This study aimed to compare the maternal and foetal outcome when amniotic fluid was measured by these two methods.Methods: Hundred pregnant women at >28 weeks gestation scheduled for test of biophysical score due to various risk factors were enrolled and divided in two groups of 50 each. In each group, amniotic fluid volume was determined by either calculating the Amniotic Fluid Index (AFI) or measuring the Single Deepest Vertical Pocket (SDVP). Oligohydramnios was declared at cut off of <5 for the former and <2cm for the later method respectively. Maternal and foetal outcomes were compared between the two groups.Results: Diagnosis of oligohydramnios was 45/50 in group I and 23/50 in group II (p<0.0001). Induction of labour was done in 70.0% in group I and 18% in group II (p<0.0001). Non-reassuring foetal heart rate was seen in 36.0% in group I and 14.0% in group II (p=0.011). Rate of caesarean delivery was significantly higher in group I, 42.0% in comparison of 20.0% in group II (p=0.017). NICU admission were 32.0% in group I and 18.0% in group II (p=0.106).Conclusions: SDVP is a better choice for determining amniotic fluid to avoid unnecessary interventions without any significant improvement in peripartum outcome measures.

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.
