If you're having an operation, you'll meet a doctor like me. I'm an anesthesiologist. It's my job to make sure you're comfortable during your procedure or operation.
Before the operation, I'll start giving you a special medicine called "anesthesia." This medicine helps you sleep. As a matter of fact, you'll sleep through the whole operation! And you know what else? You won't feel a thing!
When the operation is over, I'll stop giving you the medicine, and you'll wake up. Then your doctors can let you know what you missed!
