The Evening Before
Day Surgery

  • No food after midnight the day before surgery. Clear liquids only may be taken up to 4 hours before admission. This is to reduce the chance of vomiting associated with anesthesia, and particularly, the chance of stomach acid damaging the lungs.
  • Take a thorough bath or shower, and wash your hair. Shower facilities are not available in the unit, so please take care of this at home.
  • If you have a fever, cold or infection of any kind, you must notify your surgeon.
  • Try to get a full night's sleep the night before your surgery.
  • Eat a light dinner early in the evening prior to your surgery date.

Special Instructions for Children

Patients under 18 years of age must be accompanied by a parent or guardian. One parent must be in the hospital at all times, even when the child is in surgery or recovery. Please make arrangements for other children to be cared for at home.


Planning ahead will alleviate problems following your hospital stay. Here are some suggestions on what to do beforehand.

What Surgery Patients Had to Say...

“I had surgery here and my experience was fantastic. Everything worked out beautifully. I want to shine a special light on June.  She was very nice, helpful and accommodating. She is truly a gem.  I just wanted to express my gratitude to you and to MGH”

“Lindsay was absolutely wonderful during our son’s pre-op. She took the time to make us feel he was a patient and not a number. We were doubly pleased she was part of his care before his surgery.  She is so wonderful, calm, friendly and her smile is natural. Thank you so much for having her at MGH”.

“I commend the whole process – pre-admit evaluation, surgical identity fail-safe, compassion and caring from surgical nurses, anesthesiologist, and before/after presence of the physician. I would say I received 5-star treatment.”

“My wife, Cecilia had to have her gallbladder removed. I was very happy with the amount of loving care she received. June was very caring and gentle. And Daryl in DI, who performed the hydra scan, was also extremely caring and took good care of her. Thank you, MGH!”

“My surgical experience in July, 2010 was excellent. From the first person to the last, including anesthesia, all took the time to talk to me and made sure I understood. They all worked as a team and are so good to each other and to the patients.”

Mason General Hospital's new, state-of-the-art Surgery Wing

The newly-constructed, 20,000 square-foot, state-of-the art Surgery Wing at Mason General Hospital was part of the Campus Renewal and Construction Project which began in April 2012. It was built to accommodate new technologies and replace the existing surgery suites. Areas included in the new Surgery Wing are, Outpatient Services, a Post Anesthesia Care unit, three operating rooms, two endoscopy rooms, a central sterilization area for the Surgery Department, a lab draw station, and surgery support space.

The staff in the Ambulatory Surgery department at Mason General Hospital is pleased to serve you during your upcoming surgery. We hope that your entire experience with us will be a positive one. We feel that you need to be as informed as possible to partner with us in your care. So please read the following carefully. If you have any questions, please call us.

Preparing for Day Surgery

Prior to your surgery, you will need to visit our Pre-Admission Clinic at MGH to pre-register. Be prepared to give the phone numbers and addresses for yourself and next-of-kin.

  • Please bring any insurance numbers, cards or billing forms with you. This visit will make your admission for surgery easier.
  • The Pre-Admission clinic at the Hospital is open from 9 a.m. to 5 p.m., Monday through Friday. This is a service offered free of charge to surgery and procedure patients.
  • A visit to the Pre-Admission clinic will simplify your admission the day of your surgery. The nurse will gather information, make sure all your tests and paperwork are complete, and give you information about your surgery.

Your surgeon may require certain lab tests, an EKG, or scans to be performed before surgery. This may be done at the same time you pre-register in the Pre-Admission clinic. Your Pre-Admit appointment will be made by your physician/surgeon.


  • Unless otherwise directed by your physician, continue taking all your medications until midnight the night before surgery.
  • If your child is the patient, bring a favorite toy.
  • Any crutches or slings that you already own should be brought with you, if your surgeon says that you need them.

What to Wear

Wear casual, loose-fitting clothing that can be folded and stored in a small closet or special bag. All patients must wear a hospital gown at admitting time.

What Not to Wear

Remove all makeup including nail polish and perfumes before you arrive. The skin tone of your face and under your nails is an important indicator to surgery and recovery personnel during and after your procedure. Contact lenses (bring your own case), dentures, hearing aids and wigs may be removed just prior to surgery. Any foreign object is a hazard during surgery.

Please, No Jewelry. Remove jewelry (this includes wedding rings and body piercings). With safety in mind, it is very important to remove ALL body jewelry and body piercings prior to admission to the hospital for your surgery. Jewelry left on may cause pressure injuries, depending on your position during the procedure. It may also become trapped in a drape, bed, or possibly lost. There is a possibility of receiving a burn during surgery if jewelry is left on. Electrocautery is used to control bleeding and increase wound healing. The electricity from these units can travel along the surface of the body and my lead to superficial burns if contact with metal is made. Jewelry in and around the mouth must be removed to avoid dislocation and aspiration into the lungs while under general anesthesia. You, as the patient, are responsible for having the jewelry removed before surgery. You may return to the body piercing establishment to have the jewelry temporarily removed to prevent damage. For safety purposes, if jewelry is not removed prior to surgery, we reserve the right to remove the jewelry, even possibly by cutting the jewelry off.

When you Arrive

Upon arrival, please check in at the Admissions Desk (at south entrance of hospital). When you arrive at the Ambulatory Surgery Department, the nurse will prepare you for surgery. You must remove all clothing, including undergarments, and dress in a hospital gown. You will also receive a visit from the anesthetist or anesthesiologist. He or she will want to know your medical history and will discuss anesthesia with you. You will go to surgery when all these things are done and the facility is ready for you.

Accompanying Family and Friends

After you are prepared for surgery, one family member or friend may join you in your room to wait for surgery. Waiting areas for other family and friends are located throughout the hospital. They are welcome to use the cafeteria on the lower level, too.

How long will you be here?

Your stay for outpatient surgery usually lasts four to six hours from the time you check in to the time you leave. Variances are caused most frequently by unforeseen schedule changes (cancellation or emergency additions) and by a patient's particular reaction to medications and anesthetic. We cannot predict exactly when you will be ready to leave. We have a surgery waiting room for the person who will escort you home or, if you prefer, we will call that person when you are ready to leave.

After Surgery

If you have had a general or regional anesthetic, you will go to the recovery room to wake up following surgery. We will keep your family/friend informed of your status. Usually, patients stay for at least one to two hours in the ambulatory surgery area after their surgery. However, this is dependent on your ability to meet the criteria for discharge and is subject to the discretion of the surgeon and anesthesiologist. The nurse will give you written and verbal instructions regarding your medications and home care. You will be contacted by one of our ambulatory surgery nurses the day after surgery to see how you are doing. If you have any questions or concerns, be sure to ask at this time.

Other Arrangements

You must arrange for someone (not just a cab driver) to drive and escort you all the way to your residence. Drugs, including anesthetics, can alter your judgment and perception and affect your reactions. You will need someone to drive and escort you home to avoid injury to yourself and others. We encourage you to have a responsible adult remain with you 24 hours after surgery.

At Home After Surgery

When you return home, plan to rest the remainder of the day, your body needs it! You may return to work and recreational activities when your surgeon feels that you are capable.

  • Do not drink any alcoholic beverages for 24 hours after surgery, or while taking prescription medication.
  • Do not drive for at least 24 hours after surgery, or while taking prescription pain medication.
  • Do not sign any legal documents for one day after your surgery.
  • Have a responsible adult available at your home for the care of any dependents.
  • Call your surgeon's office for a follow-up visit and if you have any questions.
