Overnight Procedures

Yellowstone Surgery Center provides outpatient services where you are not ‘admitted’ and you typically go home the same day that you visited the surgery center. Overnight procedures also known as 23-hour procedure require you to ‘stay’ overnight for observation, so we can better monitor your progress.

Initial Check-In Process

You will be given a time you will be asked to check in at the provided Yellowstone Surgery Center location on the day of your surgery. (This is typically 1.5-2 hours before your scheduled surgery time.)

Billing and Insurance

Part of the check in process will include collecting insurance information and payment. Please review the information listed under Additional Procedure Information.

Patient Screening Process

If you have not already completed your Patient Screening Process with one of Clinical Nurse Liaisons (CNL), a member of staff will complete a nursing assessment and medical history.

IV and Anesthesia

You will go into Pre-Op, and prepare for your surgical procedure. For patients aged 10 years and older, will have an intravenous (IV) line started and will receive some fluids for hydration. Patients younger than 10 years of age (specific to not only age, but weight and height too), will have their IV started in the Operating Room.) These IV fluids will continue until oral fluids can be tolerated after surgery and IV pain medication is no longer required.

Your family member or significant other will be invited to sit with you until surgery, and you will then meet with your anesthesiologist. They will review your medical history, complete physical examination and discuss any concerns or questions you may have regarding anesthesia. You will be asked to sign the “Patient Consent for Anesthesia.”

What’s Next

You will then be transferred to the operating room by a nurse, and your family will be shown where to wait in the waiting room. If the patient is younger than 18 years of age, then the family must stay in the facility at all times.

Sedation and Surgery

When you arrive in the operating room, anesthetic will be administered using the same IV started in Pre-Op. For patients younger than 10 years of age, anesthesia gas will be administered in the OR and then the IV will be placed. After you are asleep, or sufficiently sedated, you will be positioned onto a bed that is specially designed for your surgery. The surgical location will be scrubbed and prepped, and the surgery will begin.

Following Surgery

  • You will be transferred to the first phase of recovery. (No family is allowed in Phase I).
  • Your surgeon will contact your family in the surgery waiting area to discuss your surgery and your condition.

Phase I: Monitoring

In the first phase of recovery, you will be closely monitored until you have recovered from anesthesia and are ready to transfer to the second phase of recovery.

  • No family is allowed in Phase I.
  • Your surgical site will be assessed.
  • Pain and Nausea will be assessed and necessary medication will be given.
  • Vital signs will be monitored.
  • Airway will be managed.

Phase II: Assessment

During recovery, the nursing staff will complete an assessment, and check your vital signs. At this time your family and visitors will be welcomed in to see you.
