Surti J, et al. - In this prospective, single-center study, researchers compared the predictive efficacy of total leukocyte counts (TC), platelet count (PC), and procalcitonin (PCT) for sepsis in neonates, infants, and pediatric patients who had undergone various open heart surgeries at their center from September 2014 to November 2015. The observed incidence of sepsis was 14% in pediatric patients undergoing cardiac surgeries. In septic patients, significantly lower TC was noted during postoperative 48 h. Overall, relative to any other hematological parameter, platelet levels were highly related to sepsis in Indian pediatric population. Sepsis was most strongly predicted by immediate postoperative level of platelet and this could be effectively used in the clinical settings.
