Is amnioinfusion beneficial for babies after preterm rupture of membranes?
Metadata[+] Show full item record
In patients with preterm premature rupture of membranes (PPROM) between 27 and 35 weeks' gestation, transcervical amnioinfusion reduces the rate of induction for presumed fetal distress, but does not alter perinatal outcomes. In pregnancies <26 weeks with PPROM and associated oligohydramnios, transabdominal amnioinfusion is successful in maintaining a fluid pocket >2 cm in only about a third of cases. However, when successful, amnioinfusion is associated with a prolongation of gestation by 3 to 4 weeks. (SOR: B, based on 1 RCT and small cohort studies.)
