A drug or combination of drugs used to reduce or prevent pain during a surgical or invasive procedure. Depending on the type of amount of anesthesia given, it can help block pain, control breathing and blood pressure and make a patient sleepy or unconscious during surgery.
There are four main types of anesthesia:
- Local Anesthesia– just a small amount is given in order to numb a small, specific area of the body
- Conscious/Intravenous Sedation – a mild amount is used to sedate a patient during a procedure. They may become sleepy and not remember the procedure
- Regional Anesthesia – used to block pain in a specific area of the body, such as having an epidural during pregnancy
- General Anesthesia – used to block pain throughout the entire body and makes a person unconscious for a period of time
