Background: Neonatal sepsis is a major cause of morbidity and mortality in newborn.Early diagnosis of neonatal sepsis is the top priority to all clinicians for early initiation of appropriate treatment which will reduce the morbidity and mortality in neonates and minimizes the unnecessary antibiotic therapy which will lead to overwhelming threat of multidrug-resistant organism.
Aims and Objectives: The recent study was undertaken to study the reliability and effectiveness of hematological parameters and Rodwell’s hematological score for early diagnosis of sepsis in neonates.
Materials and Methods: In this study,212 neonates were studied out of which 88 were blood culture proven sepsis and 39 were culture negative but hematological parameters positive probable sepsis.The rest 85 were both culture negative and hematological parameter negative and were considered normal baby and taken as control group in this study. Hematological parameters were studied in all cases included in the study which include total leukocyte count, absolute neutrophil count, immature/total neutrophil ratio, platelet count, C-reactive protein (CRP), and other components of Rodwell’s scoring criteria. Recent statistical analysis of all the components and hematological scoring system (HSS) done to find out the reliability and effectiveness.
Results: Analysis of hematological parameters showed that absolute neutrophil count, immature to total neutrophil ratio and platelet count have a better sensitivity and specificity in relation to other parameters.CRP and total leukocyte count have better specificity but sensitivity was very low.In the HSS, it has been shown that this scoring system was highly sensitive and specific with a high positive predictive value and negative predictive value.Among the different parameters studied, association of total leukocyte count(P<0.0001)and reduced platelet count(P<0.0001) is the most consistent indicator found in this study but association with CRP was found to be statistically insignificant(P=0.0703).
Conclusion: HSS system, total leukocyte count, absolute neutrophil count and platelet count are very reliable indicator for early diagnosis of neonatal sepsis which is cheap, simple, less time consuming, and cost effective.
