Prognostic Efficacy of Red Cell Distribution Width and Neutrophil/Lymphocyte in Cardiac Surgery

Objectives: This study aimed to examine the effect of neutrophil-to-lymphocyte ratio (NLR) and red cell distribution width (RDW) values on postoperative mortality and morbidity in patients who underwent off-pump cardiac surgery.
Methods: This study included patients who underwent off-pump coronary artery bypass surgery from January 1, 2018 to January 1, 2020. Correlations between the preoperative NLR and RDW values and postoperative complications, extubation time, length of intensive care unit stay, and length of hospital stay were evaluated.
Results: A total of 68 patients were evaluated. No correlation was found between preoperative RDW and NLR values and age, ejection fraction, extubation time, or length of hospital stay. The length of stay in the intensive care unit did not correlate with the preoperative RDW value but was correlated with the NLR value (p=0.042). In six patients, postoperative complications were observed. No statistically significant difference was found between patients with and without complications in terms of preoperative RDW and NLR values.
Conclusion: In this study, a high preoperative NLR value was associated with a prolonged intensive care unit stay, one of the early complications of cardiac surgery. However, the preoperative RDW value did not have a predictive relationship with early postoperative complications.
