Cesarean section and perinatal outcome: response from the House of Horne.

A direct comparison between Parkland Memorial Hospital in Dallas, Texas, and the National Maternity Hospital in Dublin, Ireland, on the basis of limited numbers taken from one year only (1983) led to the conclusion that the liberal use of cesarean section in Dallas was associated with a sevenfold decrease in intrapartum fetal deaths and a twofold decrease in neonatal seizures. However, when the scope of the survey is extended to include the year before (1982) and the year after (1984), a different picture emerges. During this extended period there were almost four times as many cesarean sections performed in Dallas with no significant difference in overall perinatal mortality, while for two of three years the incidence of neonatal seizures was twice as high in Dallas when compared with Dublin. The fact that high cesarean rates continue to rely on evidence of such a tenuous nature must remain a matter of concern.
