Abstract：
:Presented are the results over a 4-year period of the conservative management of cases of premature rupture of the membranes. Perinatal mortality in infants delivered more than 24 hours after rupture of the membranes is not higher than that in infants delivered within 24 hours of rupture of the membranes, if these results are based on pregnancies of comparable gestational age. Two independent factors influence the risk of infection: the duration of gestation, and the interval between vaginal examination and delivery. If corrections are made for these two factors, there appears to be no clear correlation between the incidence of infection and the period of time the membranes have been ruptured. Conservative management is justified if vaginal examination is avoided until delivery within 24 hours is expected to occur.
