Spinal Anesthetic Procedure: 4 Types of Anesthesia

Anesthesia renders a patient unconscious and painless during surgery or other medical procedures. General anesthesia, regional anesthesia, local anesthesia, and sedation anesthesia are the four main types. Anesthesia is determined by surgery type, medical history, and individual preferences.

General Anesthesia

General anesthesia is a type of anesthesia that renders the patient unconscious. An anesthesiologist or nurse anesthetist administers it. The patient's breathing, heart rate, and blood pressure will be monitored closely during general anesthesia. This type of anesthesia is typically used in major organ surgeries or longer procedures.

Local Anesthesia

Local anesthesia is administered to numb a particular body area. It is often used in minor surgical procedures and dental work. It is not usually used for surgeries that require more extensive anesthesia.

Regional Anesthesia

Regional anesthesia is used to numb a more significant portion of the body. Such anesthesia is usually required for arms, legs, or midsection procedures. There are two main types of regional anesthesia:

Epidural Anesthesia

Administered in the epidural space, a small space between the spinal cord and the vertebrae. Spinal anesthesia: Administered directly into the fluid surrounding the spinal cord.
