| Abstract: | Urinary oestrogen assay and serial ultrasonic cephalometry were performed on 284 patients who were considered on clinical grounds to be at risk of having a growth-retarded fetus. It was found that ultrasonic cephalometry was significantly better than oestrogens in diagnosing the small-for-dates baby, but that there was no significant difference between the two methods in predicting perinatal asphyxia. Of the 14 stillbirths, three were in the normal ultrasonic growth rate group and five had normal oestrogen excretion. Both methods were found to be of value in the diagnosis of fetal growth-retardation, although cephalometry would seem to have some advantages, especially in distinguishing between fetal growth-retardation and mistaken maturity. |
