Before you have general anesthesia, an anesthesiologist will talk with you about: • Your health history including whether you have had surgery before • Any prescription medicines, over-the-counter medicines and herbal supplements that you take • Any allergies to food or medicine that you have • Your past experience with anesthesia, such as side effects or reactions This information will help the anesthesiologist choose the anesthetics that will work best and cause the least unwanted side effects for you. Sometimes it can be started with a gas that you breathe from a mask.

In most cases, anesthesia is started with an anesthetic delivered through an I. Once you are asleep, a tube (endotracheal tube) may be inserted in your mouth and down your windpipe to make sure you get enough oxygen and protect your lungs from blood or body fluids.
