Effect of Anesthesia Method on Neutrophil-Lymphocyte Ratio

The neutrophil/lymphocyte ratio (NLR) is a simple and inexpensive marker of the inflammatory response. NLR is affected not only by surgical trauma but also by the anesthetic method. The method of anesthesia can affect NLR, thereby modulating the inflammatory response and surgical outcomes. In this study, it was aimed to evaluate the relationship between blood NLR and anesthesia techniques in patients undergoing forearm surgery, and the secondary aim was to evaluate the relationship between Platelet/lymphocyte ratio (TLR), Mean Platelet Volume (MPV) and anesthesia techniques.
