BACKGROUND According to literature, only few studies are available on correlation of umbilical artery blood gas parameters and Apgar score in high-risk pregnancy. Due to paucity of studies, we have done this study in South Indian population, particularly Puducherry for early and better detection of high-risk newborns with metabolic acidaemia. The aims of this study are-1) To compare the 1 and 5 minutes, umbilical arterial blood gas parameters between high-and low-risk pregnancies, 2) To compare

MATERIALS AND METHODS This was an analytical comparative study performed on 150 mother-foetal pairs during June 2016 to May 2017 at SLIMS, Puducherry. Apgar score at 1 and 5 minutes after birth was taken and umbilical cord blood gas analysis was done immediately after birth in both groups. Mothers who came with labour pain were divided into high and low risk, if they have had any perinatal risk factors. Other data like gestational age, birth weight, need for resuscitation and admission to the newborn ward or Neonatal Intensive Care Unit were gathered for comparison between the two groups. All the data were statistically analysed using SPSS software. RESULTS There were no significant differences in mean birth weight, gender and mode of delivery between high-risk and low-risk mothers. Significant differences were observed in 1 and 5 minutes Apgar score, umbilical artery blood pH, pCO2, pO2, Base excess, HCO3between high-risk and low-risk mother-baby pairs. According to the Spearman's Rho correlation coefficient, there were statistically significant positive correlation (p < 0.05, r= 0.2 -0.4) between 1 minute Apgar score and pH, pO2, pCO2 and Base excess in high-risk pregnancy, but there was no significant correlation between Apgar score at 1 and 5 minutes and umbilical blood gas parameters in low-risk group (r < 0.2, P > 0.05). CONCLUSION Our study highlights a correlation between 1 minute Apgar score and umbilical artery blood gas parameters in high-risk pregnancy. So we recommend assessing umbilical blood gas analysis in neonates born to high-risk mothers to detect metabolic acidaemia earlier.
