In view of controversial reports about the role of prelabour rupture of foetal membranes (PROM) in neonatal morbidity and to study the association of PROM with infections and meconium aspiration syndrome (MAS), a prospective case control study was conducted in a level II nursery of Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan. Of the 111 neonates with PROM studied, 18 developed clinical problems (septicaemia and other specific problems such as pneumonia, omphalitis, skin infection and MAS) while 5/56 of the control group developed similar problems. The difference between the two groups was not significant (p < 0.30). There was no neonatal death. It is concluded that PROM is not associated with neonatal morbidity. Neonates with this problem alone do not need to be admitted to the neonatal nursery.
