What are the classifications of anesthesia methods?

Anesthesia is usually used during surgery or wound suture. Anesthesia is usually given first. Without anesthesia, the pain caused by the surgery is unbearable for normal people. There are usually many types of anesthesia. Different types of anesthesia are used in different places. Anesthesia generally has certain risks. Therefore, when anesthesia is needed, it is best to go to a regular professional hospital.

What are the types of anesthesia methods?

1. General anesthesia

1. Inhaled anesthesia: Anesthetics enter through the mouth and nose, reach the alveoli through the respiratory tract, and then enter the blood circulation, eventually inhibiting the central nervous system and producing a state of anesthesia.

2. Non-inhalation anesthetics anesthetics enter the body through veins, muscles, etc., thereby inhibiting the central nervous system.

2. Local anesthesia

The application of local anesthetics to a certain part of the body temporarily blocks the conduction function of sensory nerves, thereby achieving the effect of anesthesia and analgesia.

1. Surface anesthesia The painless state produced by the contact of local anesthetics with strong penetration properties with local mucosa is called surface anesthesia.

2. Local infiltration anesthesia The layered injection of local anesthetics along the surgical incision to block the nerve endings in the tissue is called local infiltration anesthesia.

3. Nerve block: Local anesthetics are injected around the nerve trunk that innervates a certain area, causing localized anesthesia in that area.

4. Regional block anesthesia is the process of injecting anesthetic drugs around and at the base of the surgical area to block the nerve endings entering the surgical area.

5. Intraneuraxial anesthesia: Local anesthetics are injected into the spinal canal to block some spinal nerves, thereby producing anesthesia in certain parts of the body. Depending on the injection interval, it can be divided into subarachnoid block anesthesia and epidural block anesthesia.

(III) Combined anesthesia

Each single anesthesia method has its own advantages and disadvantages. The simultaneous use of multiple anesthetic drugs or multiple anesthesia methods to complement each other, complement each other's strengths and overcome each other's weaknesses, thereby achieving better results than a single anesthesia method, is called combined anesthesia, also known as balanced anesthesia in clinical practice.

4. Postoperative analgesia

1. Intravenous analgesia;

2. Subcutaneous analgesia;

3. Epidural analgesia;
