      • 1.
        1. One hundred cases of premature rupture of the membranes at 37 weeks' gestation or less were studied from a total of 2,481 admissions, with an incidence of 4 per cent.
      • 2.
        2. Patients with rupture of the membranes were placed on complete bed rest for 48 to 72 hours and discharged if not in labor and if, in the majority of instances, loss of amniotic fluid had completely stopped. Antibiotics were given to 39 patients. Amnionitis developed in only 2 cases, in both of which antibiotics had been given.
      • 3.
        3. Fifty per cent of the patients studied were admitted at about the thirty-sixth to thirty-seventh week of gestation. Only 25 per cent of the total number of patients studied had ruptured membranes prior to the thirty-second week.
      • 4.
        4. No etiological factor was apparent, nor did age, race, or presentation appear to influence premature rupture of the membranes.
      • 5.
        5. In 79 per cent of the patients labor began and delivery occurred within the first 72 hours after rupture.
      • 6.
        6. There were 2 cases of prolapse of the umbilical cord, a higher incidence than is usually seen.
