Additional Information

What is an Ambulatory Surgery Center?
Ambulatory Surgery Centers (ASC) are facilities where surgeries that do not require a hospital admission are performed. They provide a cost-effective and convenient environment that is less stressful than the large hospital environment.

 What time is my surgery?
Surgery Center staff will call you the day before your surgery to tell you the time to be at the surgery center. If you have not received a call from the Staff by 2pm on the day prior to your surgery, please telephone the Surgery Center and ask about your surgery.

What do I do the day before surgery?
 Do not eat or drink anything after midnight, the night before your surgery date. Also, please follow any other specific instructions your surgeon or our staff may have given you.

What should I do if something comes up and I need to cancel my surgery?
Please call the Surgery Center and your physician as soon as possible. Our phone number is (415) 346-1218. If you call after hours, an answering message will instruct you in leaving a message.

How do I know if my insurance company will cover my surgery?
 The staff at the Surgery Center as well as your physician's offices will be able to help you answer some of your questions regarding coverage. Please contact your insurance carrier regarding your specific benefits.

What should I bring the day of my surgery?
Please bring all insurance information with you. Also, wear comfortable clothes that are easy to put on and off. For example, shirts that buttons up the front or loose fitting slacks. Please leave all valuables and jewelry at home. Try to plan ahead, depending on the type of surgery you are having. Please bring any paperwork given to you by your surgeon that he/she requested you have on your day of surgery. If you have any copayment or deductable due, payment will be expected on the day of surgery. Please bring a form of payment.

Will I be able to drive after my surgery?
No, any individual that requires sedation for their surgical procedure must be accompanied home by a responsible adult. This is a safety procedure that is strictly adhered to for your benefit. You cannot take a taxi.

Will my family be able to visit me immediately after my procedure?

Due to the need for privacy we suggest that a limit of one or two family members visit the patient during the postoperative phase. The nursing staff will be happy to give family members waiting outside the recovery area periodic updates on the patient’s condition.

What if I have sleep apnea? / What if I'm over weight?

Patients with OSA requiring C-PAP and morbidly obese patients with a Body Mass Index (BMI) greater than 35 have a markedly increased risk of post-operative complications. Therefore, they may not be candidates for admission to the Surgery Center. The medical director or the attending anesthesiologist must first provide clearance before patients will be admitted for surgery.


It is very important that you are well prepared for your upcoming surgery.
We have put together information in this section of our web site that you should review in the days prior to your surgery.

Pain Management

In the PACU/Recovery Room you will be asked to rate your pain

This helps us to objectively evaluate how much discomfort you are having.
The scale that we most often use is the 0 -10 scale. 0 is no pain and 10 is the worst possible pain.

0 1     2      3 4    5    6     7 8       9       10
no pain minimal pain moderate pain worst possible pain

At Home

It is best to have someone stay with you after you arrive home from your surgery. If this is not possible, we recommend that you arrange to have someone available by phone.

Some patients have concerns about taking care of themselves when they go home. Please discuss these or any concerns you may have with your nurse during your preoperative interview.
A nurse from the recovery room will try to call you the day after your procedure to see how you are doing and answer any of your questions.
If you need to speak to a nurse, you may call the Surgery Center at (415)346-1218. A nurse is available Monday through Friday.
Your surgeon is available to you as well. You can reach him/her at their office or they can be paged through their answering service.

It is important that you fill the prescription for your pain medication.

Patients are often comfortable when leaving the surgery center and do not think they will need anything as strong as a prescription pain pill.
Many surgeons use local anesthesia at the wound site so that you will be fairly comfortable until the local anesthesia wears off, which sometimes does not occur until later in the day or even into the next day.
It is much easier to keep your pain under control than try to alleviate it with more medication once you are very uncomfortable. We recommend that you fill your prescription as soon as possible.
It is often helpful to fill your prescription before your day of surgery. Please bring your insurance card with you.

Take pain relief drugs when pain first begins

It is much easier to control your pain when you take your pain medication as prescribed.
Most patients on the day of surgery, that evening and the following day will need to take their pain medication every 4 to 6 hours.
  • As your discomfort lessens you may change taking your prescription narcotic medication to a Tylenol or ibuprofen like drug as ordered in your discharge instructions
  • As long as you are taking narcotic type medication you should not drive, drink alcohol or do anything that requires coordination or judgement activity
If the pain medication prescribed for you is not effective in alleviating the discomfort, you should contact your surgeon. 
Please follow the advice of your surgeon if ice and/or elevation to the surgical area is recommended.

Some pain medications can cause constipation
If this happens, you may take a stool softener (such as Colace), or a gentle laxative (such as Milk of Magnesia).
You do not need a prescription for these medicines.

Do not drive while you are taking "narcotic" pain medication.
This includes medicine like Percocet, Tylenol #3, and Vicodan.

Prescription Pain Medications and Non-Narcotic Pain Medications

Below we have provided general information about some of the commonly prescribed pain medications. The information provided here does not contain a full description of the medication listed. For specific medication information, such as dosage, adverse effects, side effects and possible contraindications, please consult your pharmacist.

All of these medications are best taken with food in your stomach such as a few crackers or toast.

Non-Narcotic Pain Medications


  • These medicines reduce swelling, fever, inflammation and mild to moderate pain after surgery.
  • They can lessen or eliminate the need for stronger medications.
  • NSAIDS can be used alone or in combination with narcotic pain medication to help control more severe pain.
  • They are not addictive.
  • NSAIDS can interfere with blood clotting.
  • They may cause nausea, vomiting, stomach pain and heartburn.
  • Check with your doctor or your discharge instructions before taking this medication.

Narcotic Pain Medication

(A prescription is necessary for these medications. These medications may not be refilled.)

Tylenol #3 (Tylenol with Codeine)
Vicodin (Hydrocodone)

  • Most often used for acute pain such as short-term pain after surgery.
  • They do not cause bleeding.
  • It is rare for patients to become addicted as a result of taking narcotics for post-operative pain.
  • Narcotics may cause drowsiness, nausea, constipation, itching, or interfere with urination.
  • Some of these medications contain acetaminophen (Tylenol). If you have liver disease, consult your doctor before taking this medication.
  • Do not take more medication than prescribed by your doctor.
  • Do not drink alcoholic beverages while taking these medications.
  • If you are taking the medication as directed and you do not have pain relief, please call your doctor.

Operating Room

Who will be in the operating room with me?
Your peri-operative team consists of your surgeon and their assistants, nurses, anesthesiologists and a surgical technician.
Where do I go to sleep?
You will be prepared for your surgery in the pre-operative holding area where you may receive some sedation to reduce your anxiety and make you sleepy. Your anesthesia will be administered in the operating room.
How do I get to the Operating Room?
You will be transported on a stretcher accompanied by your anesthesiologist and nurse. Once in the room you will be assisted in transferring to the operating room bed.
How will I be positioned in the operating room?
The operating room team will assist you to a comfortable position on the operating room bed. If you have back problems or difficulty lying flat, please let the nursing staff know so we can take extra care in positioning you for your surgery.
Why is the operating room so cold?
The operating room temperature is kept low for several reasons: the maintenance of our equipment, the sterility of our supplies, for the comfort of your surgical team who are required to wear long sterile gowns and work under hot lights. We provide you with warm blankets as soon as you are settled in the operating room.
Will I be able to see my surgery being performed?
We find it best for our patients not to see the actual procedure. If you chose a type of anesthesia where you are awake, the operating room team will keep you informed of the progress of your surgery.
Why is there so much equipment in the room?
Our ambulatory operating rooms are fully equipped for all types of surgical procedures. This means that much of the equipment and supplies you see may not be necessary for your procedure.
Are family members allowed into the operating room?
Family members are not allowed into the operating room for safety and sterility reasons. If your family member does not speak English or has communication difficulties, an interpreter will be provided who has been trained to assist the operating room staff.

Recovery Room

The PACU, post anesthesia care unit or recovery room, is the name of the room where you will recover from your surgery and anesthesia. An experienced post anesthesia care nurse and anesthesiologist will be there to care for you during this time.

Frequently Asked Questions About the Post Anesthesia Care Unit

What happens in the PACU/Recovery?

During your recovery you will be placed on a heart monitor that continuously monitors your pulse and blood pressure.
A finger cover is placed on your finger. It tells us how much oxygen is in your blood and how well you are breathing.
Your temperature will be taken by placement of a small probe in the outer ear canal. It is a quick way to check your temperature. You will feel a slight pressure in your ear when this is done.
When you first wake up you may have an oxygen mask covering your mouth and nose. It is important to keep it on until your nurse removes it.
If you have an incision or bandage, your nurse will be checking the area for any bleeding.
When you are awake and ready for fluids, you will start drinking small sips of water.

How will I feel after surgery?

You may feel sleepy, dizzy and/or forgetful from the medications given to you during your operation. These feelings will improve as time passes.
You may have some discomfort after your surgery. The nurses will give you medication to make you feel better.
If you have had a spinal anesthetic or a nerve block to an extremity, the extremity will feel numb and heavy and you may not be able to move it. This is not cause for worry. The normal feeling and movement will return with time as the medication wears off.

How long will I be in the PACU?

The average recovery time is usually between 30 to 90 minutes. Since each person is unique recovery time will vary.
  You can be discharged home when you are reasonably comfortable, awake and alert, pain is manageable and you have minimal nausea.

Will someone explain to me what I should do when I get home?

Before you are discharged home, the nurse caring for you will review your discharge instructions with you and your family.
All of your questions will be answered before you go home.
  Our phone number will be given to you to call if you have questions.
Always feel free to call your surgeon for any questions or problems.
If you do not know your surgeon's phone number, please call the Surgery Center @ (415) 346-1218.
