Fetal Hypoxia and Breech Delivery

ALTHOUGH A number of clinical and pathologic studies are concerned with the fetal risks inherent to breech delivery, research concerning the potentially hypoxigenic influence of this type of fetal presentation is remarkably scanty. Because it has repeatedly been suggested, although not convincingly proven, that the higher perinatal morbidity and mortality attached to breech delivery are attributable, at least in part, to a decreased fetal oxygen supply,' "' '"• 17 we have attempted to analyze this type of delivery from this particular angle. Hence, the purpose of the present study was to find out whether the risk of fetal hypoxia is indeed significantly higher in uncomplicated breech deliveries than it is in spontaneous uncomplicated vertex deliveries.
