Abstract
To improve care for extremely premature infants, the development of an extrauterine environment for newborn development is being researched, known as Artificial Placenta and Artificial Womb (APAW) technology. APAW facilitates extended development in a liquid-filled incubator with oxygen and nutrient supply through an oxygenator connected to the umbilical vessels. This setup is intended to provide the optimal environment for further development, allowing further lung maturation by delaying gas exposure to oxygen. This innovative treatment necessitates interventions in obstetric procedures to transfer an infant from the native to an artificial womb, while preventing fetal-to-neonatal transition. In this narrative review we analyze relevant fetal physiology literature, provide an overview of insights from APAW studies, and identify considerations for the obstetric procedure from the native uterus to an APAW system. Lastly, this review provides suggestions to improve sterility, fetal and maternal well-being, and the prevention of neonatal transition.

Abstract
INTRODUCTION Bilateral renal agenesis (BRA) is a lethal diagnosis, specifically meaning that natural survival beyond birth is not expected secondary to pulmonary hypoplasia. Limited contemporary data are available about intervention and the impact of restoring amniotic fluid volume in relation to the risk for lethal pulmonary hypoplasia and other factors that might influence survival in cases of fetal BRA. OBJECTIVE We report the largest series of patients undergoing fetal intervention and postnatal care for BRA at a single comprehensive fetal center. METHODS All patients with fetal BRA were reviewed from January 2004 to November 2017. Maternal and neonatal data were collected in an institutional review board-approved retrospective review. RESULTS From 2014 to 2017, 20 singleton pregnancies with isolated fetal BRA were evaluated and 14 had amnioinfusion. Eight had serial infusions. Of those, there were 6 neonatal deaths. There were 2 neonatal survivors beyond 30 days; however, both died of sepsis on dialysis. One of these survivors received amnioinfusions by percutaneous approach and one via amnioport. There were no survivors to transplantation. CONCLUSION Fetal intervention via amnioinfusion may promote pulmonary survivorship after birth, but postnatal survival remains poor. Future studies must place an emphasis on standardizing the postnatal approach to this patient population.

Abstract
OBJECTIVES To evaluate the maternal, perinatal and long-term prognosis in the event of previable premature rupture of the membranes (PROM) and to specify the interventions likely to reduce the risks and improve the prognosis. METHODS The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS Previable PROM is a rare event whose frequency varies from 0.3 to 1% according to estimates (NP4). When occurring as a complication of amniocentesis, the prognosis is generally better than when spontaneous (NP3). Between 23 and 39% of women will deliver in the week following PROM and nearly 40% of women will not have given birth 2 weeks after (NP3). The frequency of medical termination of pregnancy varies greatly according to the studies (NP4), as does that of fetal death (NP4). Hospital survival and survival rates without major morbidity as a proportion of conservatively treated patients range from 17-55% and 26-63%, respectively (NP4). Neonatal prognosis is largely dominated by prematurity and its complications (NP3). The frequency of maternal sepsis varies from 0.8 to 4.8% in the most recent studies (NP4). Only one case of maternal death is reported, although 3 cases were identified in France between 2007 and 2012 (NP3). Information is a major component of the care to be provided to women and their partners (Professional consensus). An initial period of hospitalization may be proposed after previable PROM (Professional consensus). Thereafter, there is no argument to recommend hospital management rather than extra-hospital management when there is no argument in favour of intrauterine infection (Professional consensus). An evaluation of the amount of amniotic fluid by ultrasound may be proposed at the initial consultation and after a period of 7 to 14 days if pregnancy continues (Professional consensus). Prophylactic antibiotic treatment is recommended as soon as PROM is diagnosed (Professional consensus). The gestational age at which corticosteroid therapy may be proposed will depend on the thresholds selected for neonatal resuscitation care. In particular, it will take into account parental positioning (Professional consensus). From the time of the decision to perform neonatal resuscitation until the gestational age of 32 weeks, it is recommended to administer MgSO4 to the woman whose delivery is imminent (Grade A). Tocolysis is not recommended in this context (Professional consensus). In certain situations, meeting strictly the conditions mentioned by the CSP article L. 2213-1, a maternal request for medical interruption of pregnancy may be discussed. CONCLUSION The levels of evidence of scientific work on the management of previable PROM are low, therefore, most of the recommendations proposed here are based on professional agreement by "reasonable" extension of recommendations valid for later gestational ages.

A Novel Approach to Serial Amnioinfusion in a Case of Premature Rupture of Membranes Near the Limit of Viability. AJP Rep 2018; 8:e180-e183.

Abstract
Prelabor rupture of the membranes (PROM) near the limit of viability is associated with significant risks for both mother and fetus. Preterm labor, intra-amniotic infection, and placental abruption are the immediate risks to the pregnancy; however, the fetus incurs additional risks related to the sequela of persistent oligohydramnios. Transabdominal intra-amniotic infusions have been studied. Results, suggesting that this intervention may prolong the latency period, and potentially, decrease pulmonary hypoplasia in surviving neonates without evidence of increasing risk of intra-amniotic infection. To our knowledge, the use of antibiotic-infused fluid has not been reported in this clinical scenario. Therefore, we present a case of a patient with PROM before the limit of viability who underwent serial transabdominal amnioinfusions with oxacillin-containing normal saline, which resulted in membrane resealing and neonatal survival with no additional maternal morbidity.

Abstract
OBJECTIVE To determine the association between amniotic fluid index (AFI) and perinatal outcomes in preterm premature rupture of membranes (PPROM). METHOD A retrospective cohort study was conducted between 2008 and 2012. 86 pregnant women were included, with a diagnosis of PPROM and gestational age from 24 to 35 weeks. Women who presented hypertensive disorders, diabetes, fetuses with birth defects and infection at admission were excluded. To determine the association between AFI and perinatal outcomes, chi-square and Fisher's exact test were used if necessary, as well as risk ratio (RR) and 95% confidence intervals (95CI). Correlation between AFI and perinatal outcomes was determined by using simple linear regression, and AFI progression during pregnancy was analyzed by Z-test. RESULTS When comparing newborns presenting ultrasound with AFI<5cm and AFI>5cm, there was a higher frequency of perinatal mortality when the AFI was lower than 5 cm. However, when the oligohydramnios was diagnosed as severe (AFI<3cm), there was a higher frequency of Apgar scores less than seven at 1 minute, neonatal sepsis and early neonatal mortality compared to those presenting AFI>3cm. There was a positive correlation between AFI and gestational age at delivery, birth weight and Apgar scores at minutes 1 and 5. There was also a decrease in amniotic fluid volume with increased gestational age. CONCLUSION The presence of severe oligohydramnios after PPROM contributed to a higher frequency of perinatal complications and death.

Abstract
OBJECTIVE It was the aim of our study to evaluate the independent effect of preterm prelabor rupture of membranes (PPROM) as a cause of preterm delivery on mortality during primary hospital stay and significant morbidities in very-low-birth-weight (VLBW) infants < 32 weeks of gestation. DESIGN Observational, epidemiological study design. SETTING Population-based cohort, German Neonatal Network (GNN). POPULATION 6102 VLBW infants were enrolled in GNN from 2009-2012, n=4120 fulfilled criteria for primary analysis (< 32 gestational weeks, no pre-eclampsia, HELLP (highly elevated liver enzymes and low platelets syndrome) or placental abruption as cause of preterm birth). METHODS Multivariable logistic regression analyses included PPROM as potential risk factors for adverse outcomes and well established items such as gestational age in weeks, birth weight, antenatal steroids, center, inborn delivery, multiple birth, gender and being small-for-gestational-age. RESULTS PPROM as cause of preterm delivery had no independent effect on the risk of early-onset sepsis, clinical sepsis and blood-culture proven sepsis, while gestational age proved to be the most important contributor to sepsis risk. The diagnosis of PPROM was associated with an increased risk for bronchopulmonary dysplasia (BPD; OR: 1.25, 95% CI: 1.02-1.55, p=0.03) but not with other major outcomes. CONCLUSIONS The diagnosis of PPROM per se is not associated with adverse outcome in VLBW infants < 32 weeks apart from a moderately increased risk for BPD. Randomized controlled trials with primary neonatal outcomes are needed to determine which subgroup of VLBW infants benefit from expectant or intentional management of PPROM.

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.
