(Am J Obstet Gynecol. 2015;213(3):373.e1–e7) A lack of oxygen during the intrapartum period is a well-known and significant factor leading to cerebral palsy and mortality in infants. The degree of risk can be estimated after delivery by examining pH levels in the umbilical artery. An arterial pH of <7.00 along with a base deficit of 12 mmol/L or higher is believed to be particularly significant in predicting morbidity. The authors of this study have attempted to evaluate this association, hypothesizing that the level of arterial base deficit does not have any extra predictive value in acidemic neonates beyond what can be learned from the arterial pH.

ABD demonstrated no predictive value for adverse neonatal outcomes beyond using arterial pH alone.

Arteriovenous differences of [H ion] and pCO are not useful independent predictors of adverse neonatal outcomes in acidemic neonates.
