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:

General Anesthesia - Patient is unconscious and has no awareness of the surgical procedure or other sensations.

Regional Anesthesia - 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.

Local Anesthesia - A local anesthetic is injected into the patient's skin and tissue to numb a specific location.

Conscious Sedation

Conscious sedation can be divided into three stages:

  • During minimal sedation, patient is awake and feels relaxed.  Patient can understand questions and follow the physician's instructions.
  • When receiving moderate sedation, patient will be easily awakened and feel drowsy and may sleep through much of the procedure.
  • During deep sedation, patient will sleep through the procedure with little or no memory of the procedure.
