Before the Procedure

• Your physician will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.
• You will be asked to sign a consent form that gives your permission to do the test. Read the form carefully and ask questions if something is not clear.
• In addition to a complete medical history, your physician may perform a complete physical examination to ensure you are in good health before undergoing the procedure. You may undergo blood tests or other diagnostic tests.
• You will be asked to fast for eight hours before the procedure, generally after midnight.
• If you are pregnant or suspect that you are pregnant, you should notify your physician.
• Notify your physician if you are sensitive to or are allergic to any medications, iodine, latex, tape, or anesthetic agents (local and general).
• Notify your physician of all medications (prescription and over-the-counter) and herbal supplements that you are taking.
• Notify your physician if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that affect blood clotting. It may be necessary for you to stop some of these medications prior to the procedure.
• Your physician may request a blood test prior to the procedure to determine how long it takes your blood to clot.
• Notify your physician if you have a pacemaker.
• If you smoke, you should stop smoking as soon as possible prior to the procedure. This may improve your chances for a successful recovery from surgery and benefit your overall health status.
• Based upon your medical condition, your physician may request other specific preparation.
