General Anesthesia
General anesthesia is used for major operations, such as a knee replacement or open-heart surgery, and causes you to lose consciousness.
Learn about sedation and general, regional, and local anesthesia — including the differences in how each type works and when each is typically used.
All types of anesthesia are administered to keep you comfortable and pain-free during surgery, medical procedures, or tests. But there are some key differences. The type you receive will depend on factors like the procedure, your health, and your preference.
General anesthesia is used for major operations, such as a knee replacement or open-heart surgery, and causes you to lose consciousness.
Sedation is often used for minimally invasive procedures like colonoscopies. The level of sedation ranges from minimal - drowsy but able to talk - to deep.
Regional anesthesia is often used during childbirth and surgeries of the arm, leg, or abdomen. It numbs a large part of the body, but you remain aware.
Local anesthesia is for procedures such as getting stitches or having a mole removed. It numbs a small area, and you are alert and awake.
