Background: Prenatal asphyxia is a cornerstone issue influencing neonatal morbidity and mortality with long term health
impact. Foetal electronic monitoring is clinically performed in a routine manner to reflect the fetal clinical status throughout intra
partum period of time. Normal cardiotocography trace is in powerful correlation with absent academia occurrence at delivery
of the neonate. Abnormality of cardiotocographic trace on the other hand trace requires extra clinical evaluation and research
implementation. To reflect the metabolic pathways of the neonate, umbilical artery lactate have been analyzed and evaluated. Aim
of this research study is to verify the clinical power and value of umbilical cord lactate level in predictability of the unfavorable early
onset neonatal outcomes in clinical scenarios of fetal distress in intra partum period and to statistically compare and contrast the
clinical value of umbilical cord lactate and umbilical artery pH in predictability undesirable neonatal clinical outcomes having intra
partum foetal distress issues.
Methodology: 295 gestations with abnormalities of cardiotocographic traces in active stage of labor have undergone analysis
and measurement of umbilical cord blood lactate levels and umbilical artery pH measurements straight away after birth and have
been compared statistically for predictability of unfavorable newborn outcomes.
Results: In the current research study statistically calculated specificity of cord serum lactate (97.7%) and umbilical cord
arterial pH (95.97%) was displayed clearly to be almost similar in neonates with Apgar scores <7 at 1 minute and 5 minutes, but the
statistically obtained sensitivity of umbilical cord serum lactate levels (23.14%) and umbilical cord ph (31.4%) was less in neonates
with Apgar scores ≤7 at 1 minute. Area under ROC displayed and demonstrated that serum lactate levels are much more precise in
forecasting unfavorable neonatal outcomes in comparison to umbilical cord artery pH.
Conclusions: Umbilical blood lactate levels are more statistically specific than umbilical artery pH measurements in forecasting
unfavorable neonatal clinical outcomes. The area under ROC curve (at 95th percentile) have displayed that serum lactate levels is
more precise in forecasting unfavorable newborn clinical outcomes in comparison to umbilical cord artery pH at delivery.
