Clinical Evaluation of Measuring the Cord Blood Gas and Lactic Acid Analysis of Newborns in the Umbilical Artery / 中华围产医学杂志

Objective To study the plasma lactic acid and blood gas and their value in the umbilical artery of the newborns. Methods The umbilical artery blood samples of 62 newborns were obtained immediately after delivery and then blood gas analysis and plasma lactic acid values were measured within ten minutes. Results The mean value of umbilical artery plasma lactic acid was:(4.4?1.7)mmol/L,pH:7.22?0.07,Base excess:(-5.4?2.7)mEq/L. The lactic acid value had a significant negative relationship with pH values (r=-0.86,P
