The aim of this original research article was to identify the blood parameters as predictors of perinatal asphyxia and its correlation with severity of asphyxia. Setting: Postnatal Wards and Sick newborn unit of Pediatric Department, KamlaRaja, Gwalior. Design: A prospective case control study. Participants: 100 cases and 100 controls enrolled based on the selection criteria, on day 1 of life. Methods: On day 1of delivery newborns were enrolled, who fulfilled the inclusion criteria. Complete history, physical examination and neurological signs were recorded on a predesigned proforma. Hypoxic ischemic encephalopathy (HIE) Staging done. Cord blood samples were collected on day 1 and results analyzed. Results: The present study included 100 cases and 100 controls. Out of the total 100 cases, 23% (23) were HIE stage-I, 46% (46) were stage-II and 31% (31) were of stage –III Significant difference is seen in mean values of nucleated RBCs among the cases and controls (p value <0.001). It was 10.85 ± 6.39 and 5.91 ± 3.60 among cases and controls respectively. Leucocyte count was found 17.06 ± 7 among cases while among controls mean was 14.14 ± 4.15, which was significant. Similarly, significant difference was found in mean Hb among cases and control group. Polychromatophilia was found significant (p value <0.001) when compared between cases and controls and among cases themselves. The value of Positive predictive Value and Negative Predictive Value are maximum for n-RBCs. Accuracy for determining the mortality is also maximum. It is seen that area AUC for n-RBCs is maximum i.e. 0.795 which makes it the best blood parameter which correlates with mortality. Conclusions: Blood parameters are altered in perinatal asphyxia and can be used to predict the severity and outcome.
