The management of multiple pregnancies is analyzed on the basis of the results in a series of 34 triple pregnancies and 5 quadruple pregnancies. Hypertension of pregnancy occurred in 6 of the patients, a threat of severe premature delivery in 15 patients. Severe cardiovascular complications, related to beta-mimetics, occurred in one case. Delivery was virtually always by Caesarian, with a mean gestational age of 31 weeks and 5 days for the triple pregnancies and 30 weeks and 5 days for the quadruple pregnancies. In 8.4% of cases, the offspring showed severely retarded intrauterine growth. The total mortality rate was 11.7% for the triple pregnancies and 15% for the quadruple pregnancies. Most deaths during the neo-natal period occurred in offspring from 4 pregnancies in which delivery occurred before 28 weeks of amenorrhea. After 28 weeks of amenorrhea, the adjusted total mortality was 4.2% for the triple pregnancies and no offspring of a quadruple pregnancy died. The prevention of the risk of threatened very early premature delivery led us to propose routine hospitalization after 26 weeks of amenorrhea, in order to improve the foetal prognosis in this age group. Carrying out a Caesarian later, after about 34 weeks of amenorrhea for the triple pregnancies and 32 weeks of amenorrhea for the quadruple pregnancies, made it possible to reduce the incidence of delayed intra-uterine growth and in utero foetal death and also made it possible to schedule the date of delivery. Good obstetric-pediatric coordination is also an essential factor in improving the prognosis for these high-risk pregnancies.
