Preparing for Surgery

How to Prepare and What to Expect

Before Your Surgery

Follow your doctor’s presurgery guidelines, which may include instructions for diet, medicines, and/or bowel preparation. Talk with your doctor about the medications you are taking — you may need to stop taking them within a certain timeframe.

On the day before your surgery, eat a light dinner and do not eat or drink after midnight. Do not smoke after midnight. Please shower and wash prior to surgery.

To increase your chances for a successful procedure, there are steps you can follow days before you arrive at UMC. Please make sure you follow these general instructions in addition to those from your physician. We look forward to helping you.

Preregistering Before Your Surgery

Surgery preregistration will be conducted via telephone.

Please contact UMC’s Authorization Department at 702-383-2001 for assistance.


You have been instructed by your doctor to preregister at UMC. Plan on preregistering at least three days prior to your procedure. Preregistration can be done at Admitting just inside the UMC Main Entrance located on Shadow Lane and Charleston Blvd., open Monday through Friday from 8:30 a.m. to 4:30 p.m. The pre-admission process should take approximately two hours to complete, depending on the complexity of your physician’s orders. Expect to sign admission forms, discuss your health history with a pre-assessment nurse, and complete preoperative testing.

It is important for you to preregister in order to facilitate your care on the day of surgery. This also gives us the opportunity to evaluate your lab and X-ray results prior to your procedure.
