How Do I Prepare?
You will need to sign a consent form giving your doctor permission to perform this test. Tell your doctor if you have ever had an allergic reaction to lidocaine or the numbing medicine used at the dentist's office. If you are taking insulin, discuss this with your doctor before the test. If you take aspirin, nonsteroidal anti-inflammatory drugs, vitamin E or other medicines that affect blood clotting, talk with your doctor. It may be necessary to stop or adjust the dose of these medicines before your test. You will also have blood tests to find out if you are at extra risk for bleeding after the procedure.
You will be told not to eat or drink anything after midnight the night before the test. This is a safety precaution in case you are one of the rare patients that has a complication that might require surgery on the same day as the procedure.
