Monitored Anesthesia Care (MAC)

What is sedation?

Sedation is the use of medicine to help you feel relaxed and comfortable during a procedure. Sometimes it's used to help with pain.

Sedation may be used with an injection to numb the area or with other medicine to reduce pain. It's often used in procedures like a colonoscopy or a biopsy. It also can be used in many surgeries. Examples include knee surgery and hernia repair.

You may be awake and able to talk with your care team. Or you may fall asleep. You might remember little, if anything, of the procedure or surgery.

How is sedation done?

Sedation is usually given in a vein in the arm (intravenously, or I.V.).

It is often used with local or regional anesthesia. The local type numbs a small part of the body. The regional type blocks pain to a larger area of the body.

While you are sedated, a doctor or nurse will watch you closely. They'll make sure you stay safe and comfortable. In some cases, an anesthesia professional may be there during the procedure to help keep you safe. This is often called monitored anesthesia care (MAC).
