Erector Spinae vs. PENG Block for Total Hip Arthroplasty

Hip arthroplasty is one of the most common orthopedic procedures, especially in elderly patients, due to the deformation of joints. Patients may complain of severe pain due to surgical trauma and prosthesis. Regional anesthesia methods may be performed to reduce the inflammatory response, opioid consumption, and opioid-related side effects. In recent years, the influence of regional anesthesiology on reducing the inflammatory response after surgical procedures has been emphasized. However, very few studies have evaluated the effect of various methods of anesthesia on the NLR. This is the first study to investigate the effect of regional anesthesia on the NLR and PLR in patients undergoing hip replacement surgery.
