Conscious sedation for surgical procedures

Anesthesia - conscious

Definition    Return to top

Conscious sedation is a combination of medicine to help you relax (a sedative) and another medicine to block pain (an anesthetic). You will probably stay awake and be able to respond to people during a medical or dental procedure. You should not need help with your breathing.

Conscious sedation lets you recover quickly and return to your everyday activities soon after your procedure.

Description    Return to top

A nurse, doctor, or dentist, will give you conscious sedation in the hospital or outpatient clinic. Most of the time, it will not be an anesthesiologist. The medicine will wear off quickly, so it is used for short, uncomplicated procedures.

You may receive the medicine through an intravenous line (IV, in a vein) or a shot into a muscle. You will begin to feel drowsy and relaxed very quickly. If your doctor gives you the medicine to swallow, you will feel the effects after about 30 to 60 minutes.

Your breathing will slow down, and your blood pressure may drop a little. Your nurse or doctor will monitor you every 3 to 5 minutes during your procedure to make sure you are okay. You may receive extra oxygen through a mask or IV fluids through a catheter (tube) into a vein.

You may fall asleep, but you will wake up easily to respond to people in the room. After conscious sedation, you may feel drowsy and not remember much about your procedure.

Why the Procedure is Performed    Return to top

Conscious sedation is safe and effective for patients who need minor surgery or a procedure to diagnose a condition.

Risks    Return to top

Conscious sedation is usually safe. However, if you are given too much of the medicine, problems with your breathing may occur. A doctor or nurse will be watching you during the whole procedure. Health care providers should have special equipment to help you with your breathing if needed.

During the days before your procedure:

On the day of your procedure:

After the Procedure    Return to top

After conscious sedation, you will feel sleepy and may have a headache or feel sick to your stomach. Your finger will be clipped to a special device (pulse oximeter) to check the oxygen levels in your blood. Your blood pressure will be checked with an arm cuff about every 15 minutes.

You should be able to go home 1 to 2 hours after your procedure.

When you are home:
