Effect of adding Dexamethasone to Periarticular Nerve Group Block in Patients undergoing Total Hip Arthroplasty
Hip arthroplasty is one of the most common orthopaedic procedures, especially in elderly patients, due to the deformation of joints. Patients may complain of severe pain due to surgical trauma and prostheses. Regional anaesthesia methods may be performed to reduce the inflammatory response, opioid consumption, and opioid-related side effects.
