Reference Values for Umbilical Cord Blood Gases of Newborns Delivered in Enshi Tujia and Miao Autonomous Prefecture

摘要

Objec tive: To define the normal ranges of umbilical cord blood values in Enshi Tujia and Miao Autonomous Prefecture. Methods: 1266 normal newborns were screened as umbilical cord blood gas samples. Normal neonates are full-term live pregnancies, single births, weight suitable for gestational age and heavier than the gestational age of the newborn without complications. Re-sults: The umbilical cord blood collected from 1266 newborns was analyzed in this study. The calculated reference range of the umbilical arterial PH was 7.16 - 7.39, of SBE was ？8.25 - 1.67 mmol/L, of lactic acid was 1.4 - 7.5 mmol/L, and of HCO3 was 15.60 - 30.70 mEq/L. Conclusions: This study confirmed the normal reference value of umbilical cord blood gas analysis in Enshi Tujia Miao Autonomous Prefecture.
