Comparison of dexamethasone route of administration on ankle block duration and analgesia for foot and ankle surgery

This study is testing whether adding the steroid dexamethasone — either injected into the nerve block or given through a vein — can make pain relief last longer after foot surgery. Patients having an ankle nerve block (a type of regional anesthesia) for elective foot surgery will be randomly assigned to one of three groups. Researchers want to find out if dexamethasone extends the block and which route of giving it works best. You may be eligible if: - You are 18 years or older - You are having elective metatarsal osteotomy foot surgery - Your general health is good to moderate (ASA score 1–3) You may NOT be eligible if: - You are allergic to the local anesthetic (ropivacaine) or dexamethasone - You have poorly controlled diabetes or pre-existing nerve damage in the foot - You take high-dose steroids regularly or strong opioid pain medications - You are pregnant or have active peptic ulcer disease - You cannot understand English Talk to your doctor about whether this trial might be right for you.
