INFLUENCE OF ELECTIVE CESAREAN-SECTION AND BREECH DELIVERY ON NEONATAL NEUROLOGICAL CONDITION

Fifty-three infants born after elective cesarean section (CS), and 28 infants born vaginally in breech presentation were compared with 45 full-term controls. A quantitative neurological assessment consisting of 31 items was performed on days 1, 2 and 5 after birth. A tonus score, an excitability score and the number of optimal responses were calculated. A follow-up examination was done at 6 months of age, with a standardized neurological and developmental examination. The results showed that infants born after elective CS in both vertex and breech presentation had significantly reduced number of optimal responses during the first five days after delivery, compared to controls. They were more hypotonic and less excitable than the control infants during the first 2 days. There were no significant differences in neurological results between infants born after CS with general or epidural anaesthesia. The infants born in vaginal breech presentation showed no differences neurologically as compared to the controls on the first day. On days 2 and 5, however, they were less excitable and showed a reduced number of optimal responses. There were few differences in neurological condition between the infants born after elective CS and the infants born vaginally in breech presentation. Growth, psychomotor development and neurological status at 6 months did not differ significantly between the three groups. Our findings indicate that infants born after elective CS and vaginal breech presentation have a delayed neurological adaptation during their first days of life. These differences did not affect the physical well-being of the infants, which showed normal growth, neurology and development at the follow-up at 6 months of age. © 1990.
