Is Lower Limb Nerve Block Anesthetic Puncture Needle Risky

Lower extremity nerve block anesthesia has certain risks. The commonly used local anesthetics include procaine, lidocaine, ropivacaine, etc. If the surgical method of nerve block anesthesia is correct, there will be no side effects when appropriate drugs are used, but some people will have allergic reactions to anesthetics and excipients of anesthetics. If not done properly, local anesthetics can stray into blood vessels and lead to drug overdose, which can be dangerous.
