1. General anesthesia is a safe and effective anesthesia method, which can make patients completely painless during the operation. Before the operation, you need to fast for 24 hours, and after the operation, you need to observe for a while before eating.
2. Local infiltration anesthesia is a method of injecting local anesthetic drugs around the incision, which can alleviate the pain during the operation. This method does not need fasting and water restriction, nor does it affect the respiratory function, but it cannot completely eliminate the pain. Therefore, general anesthesia or local infiltration anesthesia is used to remove the rib stent.
