do I prepare for the test?
- You will need to sign a consent form giving your doctor permission
to perform this test. Some patients have this test done in a
clinic procedure area, while others are admitted to the hospital
for it. Generally your doctor will decide whether you need to
be in the hospital based on your medical condition. If you are
not staying in the hospital afterward, you should arrange for
a ride home.
Talk with your doctor ahead of time if you are taking insulin,
or if you take aspirin, nonsteroidal antiinflammatory drugs,
or other medicines that affect blood clotting. It may be necessary
to stop or adjust the dose of these medicines before your test.
Most people need to have a blood test done some time before the
procedure to make sure they are not at high risk for bleeding
complications. Also tell your doctor if you have ever had an
allergic reaction to the medicine lidocaine or the numbing medicine
used at the dentist's office.
Usually you will be told not to eat anything after midnight on
the night before the test. This is so you will have an empty
stomach in case you experience nausea from anti-anxiety medicines
(sedatives) or have a choking sensation or nausea when the camera
is first lowered past your throat.
