Abstract
OBJECTIVE: To examine the hypothesis that acidotic fetuses at birth have an increased catabolic state characterized by a negative nitrogen balance. STUDY DESIGN: Umbilical cord blood samples were obtained from a random, prospective series of fetuses at birth. Acidotic samples (pH<7.20) were matched with normals (pH≥7.20) according to maternal and gestational age. 3-Methylhistidine was analyzed in order to assess catabolic breakdown of muscle protein. RESULTS: 3-Methylhistidine was significantly increased (P <.05) in cord blood from acidotic fetuses when compared with controls and correlated negatively (P <.05) with umbilical arterial pH. CONCLUSION: Umbilical cord blood 3-methylhistidine may be used to assess fetal nitrogen balance; acidotic fetuses have increased muscle catabolism.
