[Diagnostic criteria of neonatal acidosis during the first 60 minutes postpartum].
Normal deliveries (without intra-partum warning signs or symptoms of neonatal asphyxia) were selected to form a normal population of newborns from which normal values were calculated for the pH of umbilical artery and heel prick blood at birth and 15, 30 and 60 minutes after delivery. The following lower limits were found: (formula: see text) These limits were checked for usefulness in a random population. In the light of this information the Swiss Group for Neonatology has redefined the terms "intrapartum warning signs" and "neonatal asphyxia".
