What is Anesthesia?

Anesthesia means "without sensation" or a "reversable lack of awareness".

Types of Anesthesia

There are three main categories of anesthesia: general, regional and local:

When general anesthesia is administered the patient is unconscious and has no awareness of the surgical procedure or other sensations.

When regional anesthesia is administered the patient receives an injection of medication near a cluster of nerves to numb only the area of the body that requires surgery, you may remain awake or receive a sedative.

Conscious Sedation

Conscious sedation can be divided into three stages:

  • During minimal sedation you will be awake and feel relaxed.  You can understand questions and follow your physician's instructions.
  • When receiving moderate sedation you will be easily awakened and feel drowsy and may sleep through much of the procedure.
  • During deep sedation you will sleep through the procedure with little or no memory of the procedure.
  • When local anesthesia is administered, a local anesthetic is injected into the skin and tissue to numb a specific location.
