Regional anaesthesia refers to a type of anaesthesia that involves numbing a specific part of the body. Some synonyms for regional anaesthesia include peripheral nerve block, nerve block anaesthesia, and regional nerve block. Other terms that can be used to describe this procedure include local anaesthesia, spinal anaesthesia, and epidural anaesthesia. Regional anaesthesia is often used for procedures involving the lower body and can provide longer-lasting pain relief than traditional general anesthesia. This type of anaesthesia is also associated with smaller doses of anaesthetics, which can result in fewer side effects. The specific type of regional anaesthesia used will depend on the location of the surgery and the patient's overall health.
