The night before surgery is mainly about following facility instructions, organizing logistics, and arriving prepared. This article is general education and cannot account for an individual patient, procedure, medication list, or surgical plan.
Key takeaways
- Start with the written instructions from your own surgical and anesthesia teams.
- Confirm medicines, fasting, arrival time, transportation, and support at home before the day of surgery.
- Keep identification, health information, and important contact details organized and easy to access.
- Call the care team if instructions are unclear or your health changes before surgery.
Recheck the instructions
Review the time you should arrive, where to go, and any eating or drinking restrictions given by your surgical team. These rules vary by procedure and anesthesia plan, so use your own instructions rather than a general timetable from the internet.
Review medicines carefully
Only take or hold medicines according to instructions from your clinicians. If you are unsure about a prescription, supplement, diabetes medicine, or blood thinner, contact the team. Do not make last-minute medication changes based on general advice.
For additional context, see Surgery Preparation Checklist, which explains the next related part of the perioperative pathway.
Get your belongings ready
Pack identification and required paperwork, your current medicine list, comfortable clothing, eyeglasses if needed, and any mobility aids or other items the facility specifically requested. Leave unnecessary valuables at home.
Plan transportation and support
Confirm who will take you home if same-day discharge is expected and whether someone needs to stay with you. Facilities may have specific discharge requirements after sedation or general anesthesia.
Know when to call
If you develop a fever, cough, significant illness, new symptoms, or another health change before surgery, contact the surgical team. They can tell you whether the procedure should continue as planned.
Use your own surgical instructions
Perioperative instructions vary by procedure, facility, anesthesia plan, and medical history. If this page differs from instructions given by your healthcare team, follow your healthcare team and contact them with questions.
A simple way to use this guide
Turn the information on this page into three short lists: instructions you must follow, practical tasks you need to arrange, and questions you still need answered. Keep the first list limited to directions from your own facility, especially fasting, medicines, arrival time, bathing or skin preparation, and transportation. That reduces the chance that general advice will be confused with individualized medical instructions.
Complete practical tasks early when possible. Arrange a responsible adult if required, plan for children or pets, set up the home for mobility needs, charge necessary devices, and keep identification and contact information together. Then review your questions with the care team. If something important remains unclear the evening before surgery, use the contact number provided rather than making assumptions that could lead to cancellation or an avoidable safety problem.
Frequently asked questions
Can I eat or drink the night before surgery?
Follow the fasting instructions provided by your surgical or anesthesia team. Requirements differ according to the procedure, type of anesthesia, timing, and local policy. If you are uncertain, contact the facility rather than guessing.
What medicines should I take the morning of surgery?
Take only the medicines your care team has told you to take, and follow their instructions about water or other liquids. Medication plans can differ substantially between patients, especially for blood thinners, diabetes treatments, and cardiovascular medicines.
What if I develop a fever or cough the night before surgery?
Contact the surgical team or the number provided in your instructions. New illness can sometimes affect anesthesia or the timing of surgery, so the team needs to know about meaningful changes in your health before you arrive.
