General Anesthesia Can Be Divided Into Inhalation Anesthesia And Intravenous Anesthesia

1. Inhalation anesthesia General anesthesia achieved by inhalation through the respiratory tract is called inhalation anesthesia.

2. General anesthesia caused by intravenous or intramuscular injection of intravenous anesthetics becomes intravenous anesthesia.

【Local anesthesia】means that when the drug is applied to the peripheral nerves of the body, only a certain part of the body will be anesthetized, and there will be no pain in that part.

Local anesthesia is completely reversible and does not produce tissue damage.

Commonly used local anesthesia are topical anesthesia, local infiltration anesthesia, nerve block anesthesia.

1. Topical anesthesia is the direct contact of local anesthetics with local mucosa (such as ocular mucosa, nasal mucosa, oral mucosa, etc.), penetrating the mucosa and acting on nerve endings to produce local anesthesia.

2. Infiltration anesthesia is what we often call local anesthesia. Local anesthesia is produced by anesthetizing the nerve endings in the tissue. Local infiltration anesthesia is a layered injection of local anesthetic along a surgical incision to numb the nerve endings in the tissue.

3. Nerve block anesthesia is not the use of local anesthetics for nerve endings, but the use of local anesthetics next to the nerve trunk to block the conduction function of the nerves and achieve a painless operation.

[Spinal anesthesia] also belongs to the category of local anesthesia, and is classified as a single category because of its unique dissection characteristics. Epidural anesthesia and subarachnoid anesthesia are what we call spinal anesthesia! All are spinal anesthesia.

What is the spinal canal? The spinal canal is a tubular structure surrounded by vertebrae and surrounding ligaments. Inside the spinal cord, there are pia mater, nacre and dura mater surrounding the spinal cord.

Local anesthesia methods like regional local anesthesia and local intravenous anesthesia are less commonly used.

【Sleep Anesthesia】

There is no such statement about sleep anesthesia in China. Sleep anesthesia is also called intravenous anesthesia. The method of sleep anesthesia is to inject anesthesia into the patient's vein before anesthesia to guide the patient into a sleep state, and then perform local anesthesia, thereby eliminating the pain during anesthesia and eliminating the patient's fear of surgery. After the operation, the patient seems to have just woken up from a dream and can regain consciousness in time. This method of anesthesia is generally used in large-scale hospitals that are well-equipped for monitoring.
