IV sedation, as the name suggests, an IV will be placed into your arm. The medication will be administered to keep you comfortable and sleepy. This is why it’s also called “twilight sleep” or “conscious sedation”. Although general anesthetics put you completely under, IV sedatives induce what is known as “twilight sleep” or conscious sedation”. This state means that you’re not completely unconscious, but you are much less aware of your surroundings and deeply relaxed. As a result, you will have little or no memory of the appointment afterward.
