What the trial is, and whether it could suit you

This study will compare three versions of the Pericapsular Nerve Group (PENG) block in adults aged 65 years and older who are undergoing hip surgery. The PENG block is a regional anesthesia technique used to reduce pain around the hip joint and may improve early recovery after surgery. All patients in the study will receive the PENG block using 20 mL of 0.2% ropivacaine. They will then be randomly assigned to one of three groups: Group 1: PENG block using ropivacaine only (no additional medications). Group 2: PENG block using ropivacaine with 4 mg of dexamethasone injected near the nerves. Group 3: PENG block using ropivacaine with 25 micrograms of dexmedetomidine injected near the nerves. Dexamethasone and dexmedetomidine are medications that may increase the duration and quality of regional anesthesia. It is not known whether adding one of these medications provides longer-lasting
