What should I bring to the hospital on the day of my operation?
  • Ontario health card (OHIP).
  • Toiletries such as toothbrush, toothpaste, brush, razor, soap and tissues.
  • Moisturizer for lips and skin.
  • A housecoat, socks and shoes or slippers with non-slip, rubber soles.

  • Walking aids such as a cane or walker, labelled with your name and phone number.
  • Something to read, a small amount of cash, a calling card, a cellphone, and cellphone charger.
What will happen before my operation?
  • A team of surgical nurses will help you get ready for your surgery.
  • You will change into a hospital gown.
  • If you did not see the anesthetist in the Pre-Admission Clinic, you will meet them before your operation.
  • We will shave and mark the area where we are doing your operation.
  • We will give you an intravenous (IV) drip. This is a small needle that we put in a vein in your arm. We use it to give you one or all of the following: fluids; antibiotics; pain medications.
  • When it is time for your surgery, you will got to the operating room.
What happens during surgery?
  • The surgery is done under general anesthesia. This means you will be asleep and feel no pain during surgery. The doctor will put a tube in your throat to help you breathe.
  • Your surgeon will usually make a small incision (cut) under your arm or above your collar bone. A part of your first rib and surrounding tissues are removed, relieving the pressure causing your symptoms. If indicated, the surgeon will also try to repair any damage to the blood vessels.
  • The surgeon will close your incision with stitches, and cover them with a dressing. The stitches do not need to be removed.
  • Some patients may need a chest tube to treat a collapsed lung. This is usually placed in the operating room at the time of the surgery, but may need to be put in soon after the surgery. If you need a chest tube, you will probably stay in hospital an extra 1 to 2 days and get chest x-rays every day to check that your lung has expanded well.
