This information explains how to get ready for your radiation therapy simulation or treatment if you’re getting anesthesia. Anesthesia is medicine to make you sleep during a procedure.
Follow these instructions if your healthcare provider told you that you’ll get anesthesia during your radiation therapy simulation or treatment.
Before your appointment
Take devices off your skin
You may wear certain devices on your skin. Before your simulation or treatment, device makers recommend you take off your:
- Continuous glucose monitor (CGM)
- Insulin pump
If you use one of these, ask your radiation oncologist if you need to take it off. If you do, make sure to bring an extra device to put on after your simulation or treatment.
You may not be sure how to manage your glucose while your device is off. If so, before your appointment, talk with the healthcare provider who manages your diabetes care.
Arrange for someone to take you home
You must have a responsible care partner take you home after your procedure. A responsible care partner is someone who can help you get home safely. They should be able to contact your care team if they have any concerns. Make sure to plan this before the day of your procedure.
If you don’t have a responsible care partner to take you home, call one of the agencies below. They’ll send someone to go home with you. There’s a charge for this service, and you’ll need to provide transportation. It’s OK to use a taxi or car service, but you still need a responsible care partner with you.

Instructions for eating
