Before the procedure you will undergo testing that includes blood and urine tests, chest x-ray, and electrocardiogram (EKG). You may also need additional testing depending on your health and what kind of anesthesia is used for the procedure. Pre-operative testing is usually done 2-3 days before the surgery.
If you take any blood thinners, including aspirin, you will need to stop these before the procedure. Please let your doctor know about all medications that you are taking and please bring all medication to the hospital on the day of the procedure.
If general anesthesia is used, you will need to fast, including gum and candy, from midnight on the day of the procedure. This is to reduce the risk of aspiration while under general anesthesia, though the risk is very low.
