Introduction: Metabolic disorders like hypoglycaemia and hyperglycaemia are much common in neonates as compared to any other age groups. Infants are born with a blood glucose concentration of 60 to 70% of the maternal levels and it falls during the first 24 hours. Transient low blood glucose levels are common after birth as the glucose supply to neonates changes from a continuous transplacental supply from the mother to an intermittent supply from feeds.
Aim: To find out the correlation between glucose levels in cord blood and Capillary blood of neonates using glucometer soon after birth and to determine the prevalence of hypoglycaemia and hyperglycaemia among the study population.
Materials and Methods:The study was a hospital based cross-sectional study and the study population included 1100 newborns who satisfied inclusion criteria. The glucose measurements were obtained using standard equipments and procedures. Data coded and entered into Microsoft excel, then analysed using SPSS software.
Results: Results showed that there was a significant correlation between cord blood glucose and capillary blood glucose values (Pearson correlation coefficient r=0.894, p<.001). Linear regression done for predicting capillary blood sugar from cord blood sugar. The prevalence of hypoglycaemia as per the current study is 6.5%. Hyperglycaemia was detected in two of the study population accounting for 0.2%.
Conclusion: There is significant correlation between cord blood glucose and capillary blood glucose. The prevalence of hypoglycaemia was higher among low birth weight babies. So cord blood glucose values can be used as a predictor for hypoglycaemia and hyperglycaemia in newborns soon after birth. Thereby early detection and intervention of these glycaemic disturbances can prevent grave complications.
