Additional Pre-Op Instructions:

  • Clothing should be loose, comfortable and easy to take off and put on after surgery.
  • Please be sure your family member brings a sweater/blanket while waiting, the room may be cold.

Any change in your physical condition, such as a cold, fever, persistent cough or rash, should be reported to your surgeon before the day of surgery. If this occurs, please call the surgeon's office to discuss if your surgery should be rescheduled.

If you have not provided information regarding prescription or over-the-counter (OTC) drugs to the pre-admission nurse, please bring a complete list with the names of the drugs, doses, and times taken. If you take Aspirin, Coumadin, Plavix, or Lovenox, please call your surgeon’s office to see if you need to stop taking your blood thinners prior to surgery.

Day of Surgery Itinerary


You will arrive at least 2 hours prior to your scheduled procedure. This is to allow for the necessary clinical care (changing into hospital gown, vital signs, IV start, lab work, medication administration, etc.) prior to your surgery. Be prepared to provide a urine sample for any possible labs that may be ordered they day of surgery.

Prior to surgery, your surgeon and anesthesiologist will see you and answer any questions you may have. Our multidisciplinary team will perform a safety assessment during which you may be asked the same questions multiple times. Your family is welcome to stay with you during this phase of your care.

While in Surgery

Your family may wait in the 2nd Floor Day Surgery waiting room. Once surgery has started, the operating room nurse will either call the waiting room and provide updates for your family or send text updates to the family's phone number provided at check-in.

Phase 1 Post-Anesthesia Care Unit (PACU) - Recovery Unit

After surgery is complete, the surgeon and/or the surgery team will visit the waiting room or call your designated family member to provide an update. Once you are stable, your anesthesiologist and the operating room nurse will transport you to the PACU/Recovery area.

While in the Recovery room, the nurse will monitor your airway, stabilize vital signs and manage any pain and nausea. The anesthesiologist will assess you prior to discharging you from PACU. Once you have met all criteria, a transfer will take place to the next phase of care.

Phase 1 PACU is a closed recovery unit; you will see your family after you have left the PACU recovery area. If you are going home, you will be transferred to the Phase 2 Recovery unit. One (1) family member will be asked to the unit to assist with the discharge process.

If you are being admitted, a room will be requested, and you will be transferred once it is available. Your recovery leadership team will be working diligently to assign you an in-patient room. If you are experiencing a longer than expected wait time for an inpatient room assignment (greater than 4 hours), arrangements will be made for one (1) family member to have a brief visit with you in PACU.

Estimated length of Phase 1 recovery: 1½ - 2 Hours

Phase 2 Recovery - Discharge Unit

If you are going home after your surgery, this will be the last phase of your stay with us. You can expect to be sitting up in a recliner, and your designated family member will be invited to join you. You will be offered fluids to drink and a light snack. Once your pain is tolerable and discharge criteria are met, you will be discharged home with a responsible adult. You will be provided with a packet of discharge instructions.

Estimated length of Phase 2 recovery time: 1 - 3 Hours

Please understand that these times are estimates. Should you require special attention, for any reason, we will do our best to provide it.
