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.

Inclusion Criteria:

• Underwent forearm surgery
• Between aged 18-70
• Under general anesthesia or peripheral nerve block

Exclusion Criteria:

• acute infection
• morbid obesity
• chronic treatment with steroids or immunosuppressants
• recently received chemotherapy
• hepatic and renal dysfunction;
• chronic alcohol abusers
• Multiple trauma
• Patients with missing data in their files

Patients aged 18-65 years who have underwent forearm surgery
