It is associated with maternal and perinatal morbidity and mortality.1 There is good evidence and consensus that immediate delivery at term will improve outcome and maternal satisfaction. In PPROM prior to 34 0/7 weeks, risks of prematurity outbalance the risks of expectant management. However, when PPROM occurs in late preterm (between 34 and 37 weeks), there is limited and inconsistent evidence to guide clinical practice.2 The risks of delay, such as placental abruption, ascending infections, neonatal infection and cord prolapse, should be balanced against risks of …
