MAC stands for monitored anesthesia care. It is provided by an anesthesiologist and is used for lighter or shorter procedures and does not require the use of a breathing tube. You will receive sedatives and painkillers through your IV to keep you relaxed and comfortable. You may even lightly sleep. The surgeon frequently injects local anesthesia at the site of your operation to make it numb.
You may receive oxygen through a plastic tube under your nose. The anesthesiologist or nurse anesthetist will monitor your blood pressure, heart rhythm, and blood oxygen level throughout the surgery. You will require a driver to take you home after this type of anesthesia.
