Triplet pregnancy.

A series of 14 triplet pregnancies has been analyzed. The older triplet mother had a better chance of fetal survival than the younger mother. Parity did not appear to have much effect on fetal survival but the maturity of the infants at birth had more influence than did birth weight, on their survival. The interval between the delivery of the second and third infants did not correlate with the poor prognosis for the last infant. Spontaneous breech delivery appeared to have a worse prognosis than assisted breech delivery. There was a high incidence of girls and they appeared to do better than the boys. There was a high incidence of monozygotic twin pairs in these triplet pregnancies.
