Regional anesthesia is a medical technique that numbs a specific area of the body to prevent pain during surgery or other medical procedures. Unlike general anesthesia, which affects the entire body and induces unconsciousness, regional anesthesia allows patients to remain awake and alert while blocking sensation in targeted regions. Common methods include epidural and spinal anesthesia. This approach is often used for surgeries on the lower body, such as those involving the hips or knees. It can also provide pain relief during labor and delivery. Regional anesthesia is generally considered safe and can lead to quicker recovery times compared to general anesthesia.
