Anesthesia is used to temporarily numb specific areas of the body for medical purposes, and it can be completed with or without loss of consciousness.
There are four general types of anesthesia for surgery:
- Local anesthesia: Numbing the tissue with medication at the exact spot where the surgery is required.
- Local anesthesia with intravenous (IV) sedation: Numbing the tissue and giving medication into your vein to make you more relaxed, drowsy, and comfortable.
- General anesthesia: The administration of medication by an anesthesiologist, or certified registered nurse anesthetist in cooperation with your anesthesiologist, to make you completely unaware of any sensations throughout your entire body.
- Regional block: Numbing the specific part of the body that will undergo surgery. This is performed by the anesthesiologist and often includes intravenous sedation.
