Pediatric Patient Instruction Checklist

Preparing for your Surgery

  1. Smoking and Tobacco Cessation
  2. Why can't I have anything to eat or drink after midnight the night before surgery?
    • Because stomach contents are hazardous when having any type of anesthesia. THIS IS THE MOST IMPORTANT PRE-PROCEDURAL INSTRUCTION – Do not eat, drink, smoke, chew gum or have candy after midnight the day before surgery (unless otherwise instructed). Failure to follow these instructions may result in cancellation of surgery due to the possibility of vomiting and/or aspiration (breathing in of stomach contents into the lungs). This could result in pneumonia or even death. No alcohol, street drugs, or marijuana 24 hours before surgery or procedure.
    • This includes water, ice chips, gum, breath mints, chewing tobacco, smoking tobacco, coffee, and vitamins
    • Consult the Admission Access nurse to learn when children under age four may have something to eat or drink as these guidelines are different depending on age.
  3. What about my medications?General information is listed below. Your admission access nurse will direct you on what medications to take before your procedure.
  4. What if I feel ill before my procedure?
  5. How should I get ready?
  6. What should I bring with me?
  7. Should someone come with me?
