Reasons for Procedure
General anesthesia is used for a surgery or a procedure that would be uncomfortable if you were awake. The medicine will help to:
- Prevent pain
- Relax the muscles
- Stop certain reflexes
- Prevent awareness of what is happening
What to Expect
Prior to Procedure
You will meet with a specialist before surgery. They will ask about overall health and any previous reaction to anesthesia. It is also important they know about any medicine that you are taking.
Food and drink may need to be avoided starting the night before the surgery.
Description of the Procedure
Some medicine may be given before anesthesia. It can help to prevent problems, such as nausea and vomiting. General anesthesia is broken down into 3 phases:
- First phase—Medicine will be given through an IV or as gas through a mask. It will lead to loss of consciousness. A breathing tube will be placed down your windpipe. It will support your airway during surgery. A machine may also help you breathe.
- Middle phase—Medicine will be given in this phase based on your response. Adjustments will be made to keep you asleep and keep breathing and heart rate where it should be.
- Recovery phase—The anesthesia will be slowly reversed. New medicine will allow you to wake up. The breathing tube will be removed when you start to wake.

How Long Will It Take?
The time will depend on the type of surgery.
How Much Will It Hurt?
General anesthesia numbs all pain. The brain will not sense any pain signals.
Average Hospital Stay
The hospital stay will depend on the surgery. A poor reaction to anesthesia may require a longer stay as well.
Anesthesia can have some effects for 24 hours or longer. It may include fatigue or nausea. Major decisions or dangerous activity should be avoided.

- Signs of infection, including fever and chills
