“…Although the role of amniotic fluid as a predictor of mortality has recently been questioned [9,18], our data, including a larger number of women, and in line with previous reports [1,4,12,30,31], suggest that the presence of a lower LVP at admission is associated with a significantly higher rate of perinatal mortality.…”

“…However, the definition of prolonged oligohydramnios remains unclear [2,4,9,10,15,16,18]. A precise definition of prolonged oligohydramnios would help obstetricians and parents in the decision-making process regarding the perinatal mortality.…”

“…According to Brumbaugh et al [9], the main determinant of neonatal survival to discharge was gestational age at delivery. Likewise, Hunter et al [18] analyzed the amount of amniotic fluid as a predictor of neonatal survival to discharge and found it did not predict neonatal survival.…”

Introduction: To evaluate the largest vertical pocket (LVP) of amniotic fluid as a time-dependent factor to predict perinatal mortality in women with early preterm premature rupture of membranes (EPPROM). Material and Methods: Observational cohort studyof singleton pregnancies with EPPROM <24 weeks. Termination of pregnancy (TOP) was considered if the LVP was <2 cm at 7 days. The maternal and neonatal characteristics of ongoing pregnancies were recorded. Prediction of perinatal mortality was estimated based on the influence of the LVP as a time-dependent factor after adjustment for maternal age, prior invasive procedure, and gestational age at EPPROM. Results: Of 104 women, 39 requested TOP. Neonatal survival to discharge was 40%, increasing to 74% if pregnancies achieved 24 weeks. LVP at admission <1 cm, latency to delivery, and gestational age at delivery were independent predictors of perinatal mortality. When evaluating the LVP at different time points of gestation, the highest perinatal mortality risk was established at 2 weeks (odds ratio 14.67, p < 0.001) after membrane rupture, being 5.75 (p = 0.05) the week after and 10.93 (p = 0.037) beyond 2 weeks of EPPROM. Discussion: When LVP measurement, gestational age at EPPROM, maternal age, and prior invasive procedure were considered, we found that the worst prognosis related to perinatal mortality was at 2 weeks after EPPROM.

“…Survival rates reported in the literature on pregnancies complicated by PROM before 24 weeks vary significantly. Studies published in the last decade report that 26% to 56% of these pregnancies result in the birth of a neonate who survives to discharge . The quoted proportion of babies admitted to a neonatal nursery who survive to hospital discharge varies from 62 to 79% .…”

Introduction: Amniotic fluid, once thought to merely provide protection and room for necessary movement and growth for the fetus, is now understood to be a highly complex and dynamic system that is studied as a data point to interpret fetal wellbeing. Methods: Assessment of amniotic fluid volume is now routine when performing a sonographic evaluation of fetal status and is an important consideration in the assessment and management of perinatal morbidity and mortality. 1 , 2 In this review, we will cover the dynamics that affect amniotic fluid volume, review methods for measurement and quantification of volume, review definitions for normative data as related to neonatal outcomes, and provide evidence based guidance on the workup and management options for oligoydramnios and polyhydramnios in singleton and twin pregnancies. Conclusions: When abnormalities of fluid exist, appropriate workup to uncover the underlying etiology should be initiated as adverse fetal outcomes are sometimes associated with these variations from normalcy.

Factors influencing survival in pre-viable preterm premature rupture of membranes

Abstract: Pre-viable PPROM has a poor prognosis, though modern neonatal management techniques may improve survival in late pre-viable PPROM. The predictive model generated from this consecutive case series of this rare condition provides valuable data for counselling patients with this condition.
