Anesthetic needle hit much what disadvantage to human body have

Anesthetics have certain harm to human body. For example, general anesthetics can inhibit brain function, affect respiration, lead to hypoxia, and even lead to respiratory circulation failure, leading to cardiac arrest. Although local anesthetics work locally, they are more toxic. Once poisoning occurs, they can also lead to respiratory and heartbeat arrest, which are side effects of anesthetics themselves.

Anesthetics are a common drug that not many people use. Anesthetics are usually used in some operations to relieve pain.

Anesthetics fall into two main categories:

1. General anesthesia

A drug inhaled through the respiratory tract or injected intravenously into the body to give general anesthesia.

2. Local anesthetics

This is an anesthetic used in the local area of surgery.

For the effect of narcotic drugs, general anesthesia can reach the brain through blood circulation, paralyze the central nervous system, and produce general anesthesia. Local anesthetics are used for local anesthesia in surgery, blocking local nerve conduction, so that the pain stimulation of the surgical site is not transmitted to the brain, so as to achieve the effect of inhibiting pain.
