What to expect on surgery day

This page will help you and your child understand what will happen on the day of surgery.

For parents navigating this important day, tips and advice can be found below. You can also learn how to treat your child’s pain once the surgery is over.

Learn about general anesthesia on AboutKidsHealth

Your child's stomach must be empty before a general anaesthetic. Follow these instructions to help your child get ready for an operation, test or treatment. Read more about General Anesthesia on AboutKidsHealth.

Plan to be at the hospital at least 2 hours before your child’s surgery. Please remember to bring your child’s health card. 

You will go to the Pre-Operative Care Unit on the second floor for registration, where they will check you in and direct you to your next step. To get there, take the yellow Atrium elevators to the second floor and look for the sign that reads “SDAU/PACU”.

Next, your child will be weighed, have their vital signs taken, their current level of health assessed and their chart reviewed.

The nurse will give you instructions about how to preform a pre-operative bath (pdf) and provide the necessary supplies, including a special pair of pajamas and slippers to wear in surgery. Once your child has changed into them, they may return to the playroom until it is their time to go for surgery.

Your child's anesthesiologist will come and meet with you before your child goes to surgery. They will talk to you about the options available to help your child relax before going into the operating room and fall asleep for the procedure, and ways to manage their pain during and after their surgery.

Someone from the surgical team will come out to speak with your family. A nurse will also come out to do their pre-operative assessment, which includes a nursing and surgical safety checklist. The surgeon may be available to see you before surgery. Child life specialists are also available to patients and families.

After your child goes in for surgery, you will be directed to the Surgical Waiting Room right beside the operating room playroom.

You can wait here while your child is in the operation; this is a good time to have a snack and something to drink to ensure you have energy to look after your child when they wake up. It is best to check in with the volunteers when you get there so they can notify you when your child is ready to see you after the surgery.

See Visiting a Patient for the latest guidelines and policies on visiting patients after surgery.
