Anesthesia is a way to control pain during a surgery or procedure by using medicine called anesthetics. It can help control your breathing, blood pressure, blood flow, and heart rate and rhythm.
Anesthesia may be used to:
- Relax you
- Block pain
- Make you sleepy or forgetful
- Make you unconscious for your surgery
Other medicines may be used along with anesthesia, such as ones to help you relax or to reverse the effects of anesthesia.
