The relationship between return of spontaneous circulation and neutrophil lymphocyte and platelet lymphocyte ratios in cardiac arrest cases

Abstract

Objective: The present study aimed to investigate the relationship between return of spontaneous circulation (ROSC) and the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) regarding the prediction of ROSC in cardiac arrest (CA) cases. Method: Among the patients who presented to the emergency department between October 1, 2016 and June 1, 2018, cases that received the diagnosis of cardiac arrest were identified. Demographic data, complete blood count (CBC) parameters, NLR and PLR, whether ROSC was achieved or not, and time to cardiopulmonary resuscitation were recorded. The patients were divided into two groups as patients in whom ROSC was achieved and those in whom ROSC was not achieved. NLR and PLR were compared between the groups and statistically analyzed. Results: In total, 216 patients were included in the study. ROSC was achieved in 54 (25%) cases. When CBC parameters were evaluated, statistically significant differences were found between the white blood cell, platelet, and neutrophil counts as well as NLR and PLR values of the groups (p<0.05). Conclusion: Data obtained in this study shows that white blood cell, platelet, and neutrophil counts as well as the NLR and PLR can predict ROSC.
