New technologies for the management of preterm premature rupture of membranes.

The catheterization described is still incomplete, posing many problems yet to be solved. However, this method has shed light on new issues, including the intraamniotic administration of antibiotics against amniotic fluid infection and fetal infection, amnioinfusion of saline for oligohydramnios, and development of artificial amniotic fluid. These issues are much easier than the nursing of extremely small premature babies and should be solved by the collective wisdom of obstetricians.
