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
INTRODUCTION Several fetal therapies involve repeated amniotic fluid intervention. We hypothesize that a minimally invasive approach can be used to safely implant an intrauterine catheter infusion system in a fetal ovine model for chronic use during pregnancy. METHOD Five pregnant sheep underwent operation between gestational days 110 and 115 (term 145 days). A Codman® implantable infusion pump was adapted for intrauterine use. The chamber was placed in the maternal flank and the tunneled catheter laparoscopically inserted into the amniotic cavity, secured with a pursestring. Three had an additional uterine anchoring suture. Ewes were sacrificed after natural delivery, and the uterus underwent gross and microscopic analyses. RESULTS There were no maternal mortalities, abortions, or preterm labor. Pumps were accessed and remained functional throughout gestation. Four ewes delivered healthy term lambs; the other delivered twins with failure to progress and demise. On necropsy, catheters secured with an anchoring suture remained in place, while the other 2 dislodged during labor. There was no chorioamnionitis by culture or histology. CONCLUSION Laparoscopically placed intra-amniotic infusion catheters were implanted safely and remained functional until delivery in an ovine model. This novel approach has promise in providing safe, durable amniotic fluid access for the potential treatment of fetal disease.

Oligohydramnios: a prospective study of fetal, neonatal and maternal outcomes in low-middle income countries. Reprod Health 2020; 17:19.

Abstract
Background Oligohydramnios is a condition of abnormally low amniotic fluid volume that has been associated with poor pregnancy outcomes. To date, the prevalence of this condition and its outcomes has not been well described in low and low-middle income countries (LMIC) where ultrasound use to diagnose this condition in pregnancy is limited. As part of a prospective trial of ultrasound at antenatal care in LMICs, we sought to evaluate the incidence of and the adverse maternal, fetal and neonatal outcomes associated with oligohydramnios. Methods We included data in this report from all pregnant women in community settings in Guatemala, Pakistan, Zambia and the Democratic Republic of Congo (DRC) who received a third trimester ultrasound as part of the First Look Study, a randomized trial to assess the value of ultrasound at antenatal care. Using these data, we conducted a planned secondary analysis to compare pregnancy outcomes of women with to those without oligohydramnios. Oligohydramnios was defined as measurement of an Amniotic Fluid Index less than 5 cm in at least one ultrasound in the third trimester. The outcomes assessed included maternal morbidity and fetal and neonatal mortality, preterm birth and low-birthweight. We used pairwise site comparisons with Tukey-Kramer adjustment and multivariable logistic models using general estimating equations to account for the correlation of outcomes within cluster. Results Of 12,940 women enrolled in the clusters in Guatemala, Pakistan, Zambia and the DRC in the First Look Study who had a third trimester ultrasound examination, 87 women were diagnosed with oligohydramnios, equivalent to 0.7% of those studied. Prevalence of detected oligohydramnios varied among study sites; from the lowest of 0.2% in Zambia and the DRC to the highest of 1.5% in Pakistan. Women diagnosed with oligohydramnios had higher rates of hemorrhage, fetal malposition, and cesarean delivery than women without oligohydramnios. We also found unfavorable fetal and neonatal outcomes associated with oligohydramnios including stillbirths (OR 5.16, 95%CI 2.07, 12.85), neonatal deaths < 28 days (OR 3.18, 95% CI 1.18, 8.57), low birth weight (OR 2.10, 95% CI 1.44, 3.07) and preterm births (OR 2.73, 95%CI 1.76, 4.23). The mean birth weight was 162 g less (95% CI -288.6, − 35.9) with oligohydramnios. Conclusions Oligohydramnos was associated with worse neonatal, fetal and maternal outcomes in LMIC. Further research is needed to assess effective interventions to diagnose and ultimately to reduce poor outcomes in these settings. Trial registration NCT01990625.

Abstract
BACKGROUND Preterm premature rupture of membranes (PPROM) is a leading cause of perinatal morbidity and mortality. Amnioinfusion aims to restore amniotic fluid volume by infusing a solution into the uterine cavity. OBJECTIVES The objective of this review was to assess the effects of amnioinfusion for PPROM on perinatal and maternal morbidity and mortality. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (2 December 2013). SELECTION CRITERIA Randomised trials of amnioinfusion compared with no amnioinfusion in women with PPROM. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion. Two review authors independently assessed trial quality and extracted data. Data were checked for accuracy. MAIN RESULTS We included five trials, of moderate quality, but we only analysed data from four studies (with a total of 241 participants). One trial did not contribute any data to the review.Transcervical amnioinfusion improved fetal umbilical artery pH at delivery (mean difference 0.11; 95% confidence interval (CI) 0.08 to 0.14; one trial, 61 participants) and reduced persistent variable decelerations during labour (risk ratio (RR) 0.52; 95% CI 0.30 to 0.91; one trial, 86 participants).Transabdominal amnioinfusion was associated with a reduction in neonatal death (RR 0.30; 95% CI 0.14 to 0.66; two trials, 94 participants), neonatal sepsis (RR 0.26; 95% CI 0.11 to 0.61; one trial, 60 participants), pulmonary hypoplasia (RR 0.22; 95% CI 0.06 to 0.88; one trial, 34 participants) and puerperal sepsis (RR 0.20; 95% CI 0.05 to 0.84; one trial, 60 participants). Women in the amnioinfusion group were also less likely to deliver within seven days of membrane rupture (RR 0.18; 95% CI 0.05 to 0.70; one trial, 34 participants). These results should be treated with circumspection as the positive findings were mainly due to one trial with unclear allocation concealment. AUTHORS' CONCLUSIONS These results are encouraging but are limited by the sparse data and unclear methodological robustness, therefore further evidence is required before amnioinfusion for PPROM can be recommended for routine clinical practice.

Abstract
INTRODUCTION Preterm premature rupture of membranes (PPROM) can result in fetal complications such as oligohydramnios. This study aimed to determine the effects of intravenous (IV) fluid bolus on amniotic fluid index (AFI) in pregnant women with PPROM. METHODS 24 women with PPROM during singleton live pregnancy of 28 to 34 weeks whose baseline AFI was ≤ 5cm were randomized into two groups. The study group received one liter intravenous fluid bolus of isotonic Ringer serum during 30-minute period. Reevaluations of amniotic fluid index in both groups were made 90 minutes and 48 hours after baseline measurement. Independent t-test and paired t-test were used to compare the two groups and mean amniotic fluid index before and after treatment, respectively. RESULTS The results of this study demonstrate that AFI decreased statistically significant in both the control and study groups. AFI decreased in both groups at 48 hours later. This decrease was not statistically significant in any group. The mean change in AFI (90 minutes and baseline) and (48 hours and baseline) between the two groups were not significant. The time between mean baseline measurements and delivery were 196.41 and 140.58 hours in the study and control groups, respectively. This difference was not statistically significant. CONCLUSION This study did not find significant impact of hydration On AFI as a prophylactic method on oligohydramnios in pregnant women with PPROM.

Abstract
OBJECTIVE The purpose of this study was to review systematically the efficacy of transabdominal amnioinfusion (TA) in early preterm premature rupture of membranes (PPROM). STUDY DESIGN We conducted a literature search of EMBASE, MEDLINE, and ClinicalTrials.gov databases and identified studies in which TA was used in cases of proven PPROM and oligohydramnios. Risk of bias was assessed for observational studies and randomized controlled trials. Primary outcomes were latency period and perinatal mortality rates. RESULTS Four observational studies (n = 147) and 3 randomized controlled trials (n = 165) were eligible. Pooled latency period was 14.4 (range, 8.2-20.6) and 11.41 (range -3.4 to 26.2) days longer in the TA group in the observational and the randomized controlled trials, respectively. Perinatal mortality rates were reduced among the treatment groups in both the observational studies (odds ratio, 0.12; 95% confidence interval, 0.02-0.61) and the randomized controlled trials (odds ratio, 0.33; 95% confidence interval, 0.10-1.12). CONCLUSION Serial TA for early PPROM may improve early PPROM-associated morbidity and mortality rates. Additional adequately powered randomized control trials are needed.

Abstract
BACKGROUND/PURPOSE Severe neonatal pulmonary hypoplasia incurs mortality rates approaching 71% to 95%. We sought to determine the utility of serial amnioinfusions through a subcutaneously implanted intraamniotic catheter to prevent pulmonary hypoplasia in fetal obstructive uropathy. METHODS Fetal lambs (n = 32) were divided into 3 groups. Group I (n = 12) underwent a sham operation, group II (n = 15) underwent a complete urinary tract obstruction via ligation of the urachus and urethra with a subcutaneous tunneled intraamniotic port-a-cath without amnioinfusions, and group III (n = 5) underwent a creation of a complete urinary tract obstruction with a port-a-cath as described in group II with serial amnioinfusions. Lung tissue was analyzed by lung volume to body weight ratios and stereology. Statistical analysis was performed by analysis of variance and Bonferroni comparisons (P < .05). RESULTS Obstructed fetuses grossly had smaller lungs than treated and control animals. Lung volume to body weight ratios were statistically significant between groups. Airspace fractions were comparable between groups I and III (average = 0.53 and 0.55, respectively), although both were significantly greater than group II (average = 0.48) (P = .049). CONCLUSIONS Serial amnioinfusions through an intraamniotic port-a-cath prevented pulmonary hypoplasia in an ovine model of complete obstructive uropathy. The use of an easily accessible device for amnioinfusions may be a viable option to treat oligohydramnios.

Abstract
OBJECTIVE To evaluate the effect of transabdominal amnioinfusion on prolongation of pregnancy, and maternal and neonatal outcomes in preterm premature rupture of membranes (pPROM). METHODS We conducted a prospective randomized controlled study of women with pPROM during singleton live pregnancy-between 26 and 33+6weeks-whose amniotic fluid index (AFI) was less than the 5th percentile. The study group underwent transabdominal amnioinfusion at admission and then weekly if their AFI fell below the 5th percentile again. The control group received expectant management. RESULTS The difference in the mean interval from pPROM to delivery between the groups was not statistically significant. Neonatal and maternal outcomes were significantly improved in the study group compared with the control group (fetal distress [10% vs 37%]; early neonatal sepsis [17% vs 63%]; neonatal mortality [17% vs 63%]; spontaneous delivery [83% vs 53%]; and postpartum sepsis [7% vs 33%]). CONCLUSION Transabdominal amnioinfusion reduced fetal distress, early neonatal sepsis, and neonatal mortality. In the study group, more participants delivered spontaneously and there were fewer cases of postpartum sepsis, although the pPROM-delivery interval was not increased.

Abstract
OBJECTIVE Antepartum amnioinfusion is a relatively recent procedure introduced with fetal medicine techniques. It is usually indicated for severe oligohydramnios in order to avoid the related complications such as pulmonary hypoplasia, the deforming effects of oligohydramnios, variable fetal heart rate decelerations and intraventricular hemorrhage. Antepartum amnioinfusion is also employed to improve ultrasound visualization in cases with oligohydramnios. Our objective was to evaluate the benefits and complications related to this procedure which is still less commonly used compared to intrapartum amnioinfusion, and whose risks are therefore not well established. STUDY DESIGN Reports of study designs identified from searches of MEDLINE, PUBMED, the Cochrane Collaboration, specialized databases and bibliographies of review articles were identified. Studies in women who underwent amnioinfusion between 1987 and 2002 were included. RESULTS AND CONCLUSIONS Amnioinfusion seems to offer several benefits, in terms of both prenatal diagnosis and favorable perinatal outcome. Most clinical experiences report that amnioinfusion is safe, both for the mother and for the fetus. However, randomized control-group studies subdivided on the basis of the cause of oligohydramnios (e.g. premature rupture of membranes, fetal growth restriction, obstructive uropathy and renal agenesis) could help to determine the advantages and risks linked to this procedure. Prospective randomized studies should therefore be encouraged, to clarify any possible doubts regarding the procedure, before it can be introduced into routine practice in the management of oligohydramnios.

Abstract
OBJECTIVE To determine the usefulness of antepartum transabdominal amnioinfusion (APTA) in reducing perinatal morbidity and mortality due to oligohydramnios. METHODS In this case-control study of 100 pregnant women with oligohydramnios, 50 received APTA and 50 were treated conservatively. These controls were matched for age, parity, and pregnancy duration with the case patients. RESULTS There was a mean 4.02-cm increase in amniotic fluid index (AFI) after amnioinfusion. Only 18% of case patients required cesarean sections vs. 46% of controls. The perinatal mortality rate was 18% among controls and 4% among case patients, and the difference was significant. CONCLUSION Antepartum amnioinfusion is a useful procedure to reduce complications resulting from decreased intra-amniotic volume. It is especially useful in preterm pregnancies, where the procedure allows for a better perinatal outcome by prolonging the duration of pregnancy.

Abstract
OBJECTIVE To evaluate the role of transabdominal amnioinfusion in improving the perinatal outcomes of pregnancies complicated by preterm premature rupture of membranes (pPROM). DESIGN A randomised controlled trial. SETTING A teaching hospital in Italy, obstetric unit. Population Women with singleton pregnancies complicated by pPROM, between 24 + 0 and 32 + 6 weeks of gestation. METHODS Patients were randomised 24 hours after admission to our referral hospital, to expectant management with transabdominal amnioinfusion or expectant management only. MAIN OUTCOME MEASURES The effects of transabdominal amnioinfusion on pPROM-delivery interval and on perinatal outcomes. RESULTS Of the 65 women with pPROM 34 met the inclusion criteria. Seventeen women were assigned to amnioinfusion (the amnioinfusion group) and the other 17 to expectant management. Compared with the control group (median: 8 days; range: 3-14), the pPROM-delivery period was significantly longer in women who underwent amnioinfusion (median: 21 days; range: 15-29) (P < 0.05). Women with amnioinfusion were less likely to deliver within seven days since pPROM (RR: 0.18; range: 0.04-0.69 95% CI) or within two weeks (RR: 0.46; range: 0.21-1.02 95% CI). In the amnioinfusion group the neonatal survival was significantly higher at each gestational age (P < 0.01, Yates's correction for Log Rank Test) with a reduction in pulmonary hypoplasia. CONCLUSIONS We demonstrated that compared with standard expectant management the treatment with transabdominal amnioinfusion after pPROM resulted in significant prolongation of pregnancy and better neonatal outcomes.

Abstract
OBJECTIVES The purpose of our study was to evaluate whether transabdominal antepartum amnioinfusion is associated with maternal complications during pregnancy and at childbirth. METHODS Fifty-three pregnant women, hospitalized for oligohydramnios and submitted to transabdominal antepartum amnioinfusion between 16 and 34 weeks' gestational age, were compared with a historic group of 42 pregnant women treated conservatively. RESULTS The study population was divided into two groups of women with ruptured and unruptured membranes (Groups A and B, respectively). The latency period between time of admission and term of pregnancy was more favorable in amnioinfused patients (Group A: 22 vs. 11 days; Group B: 30 vs. 9 days), and none of the maternal adverse events under study was significantly more common in amnioinfused patients. By contrast, maternal temperature over 38 degrees C was more frequent among controls than among amnioinfused patients with ruptured membranes (23% vs. 4%); so was the number of cesarean sections for fetal distress in Group B (50 vs. 11%). CONCLUSIONS Antepartum amnioinfusion does not appear to induce greater complications than conservative treatment for oligohydramnios, with or without premature rupture of membranes. On the contrary, this procedure seems to offer several benefits to pregnant women.
