Intravenous Regional Anesthesia

Intravenous Regional Anesthesia (IVRA) is a technique used to numb a specific arm or leg for surgery. It involves placing a tourniquet to isolate the limb and then injecting a local anesthetic into a vein. This causes the anesthetic to spread within the isolated area, providing effective pain relief while keeping the patient comfortable. IVRA is beneficial for procedures that are minor but still require anesthesia, as it allows for quick recovery and minimal side effects compared to general anesthesia.
