[Statistic evaluation of anamnestic and clinical findings in a premature labor collective of 245 cases].

245 cases of premature birth were compared from the point of view of frequency of aetiologically significant factors with 200 cases of normal birth. The perinatal progress of these premature and normal births was also followed up. It was possible to obtain statistical confirmation of the connection between prematurity and frequent occurrence of some of these parameters. Prominent amongst these are previous abortions and premature births, cervical insufficiency and malformation of the uterus, multiple pregnancies and anomalous foetal position, also placental insufficiency. Increased mortality and morbidity--including perinatal complications--were recorded at the same time. Knowledge of predisposing factors will in many cases make it possible to recognize in good time when pregnancies may be at risk and give adequate supervision and treatment where appropriate.
