Treatment of Classic Mid-Trimester Preterm Premature Rupture of Membranes (PPROM) with Oligo/Anhydramnion between 22 and 26 Weeks of Gestation by Means of Continuous Amnioinfusion: Protocol of a Randomized Multicentric Prospective Controlled TRIAL and Review of the Literature.

Background: The classic mid-trimester preterm premature rupture of membranes (PPROM) is defined as a rupture of the fetal membranes prior to 28 weeks of gestation (WG) with oligo/anhydramnion; it complicates approximately 0.4-0.7% of all pregnancies and is associated with very high neonatal mortality and morbidity.

Glucose uptake in the placenta, fetal brain, heart and liver related to blood flow redistribution during acute hypoxia.

Aim: We used positron emission tomography (PET) with radioactive glucose (F-18-Fluor-Deoxglucose [FDG]) to investigate whether acute maternal hypoxemia causes alterations of glucose uptake of fetal organs and the placenta.

Material And Methods: Investigation was performed under normal conditions and acute hypoxemia in 16 fetal sheep between 108 and 130 days of gestation. Maternal sheep were ventilated with 1.
