Bronchoscopy

If you're having a flexible bronchoscopy, a local anaesthetic will be sprayed into your nose and to the back of your throat to numb the area. You're likely to be given intravenous sedation to make you drowsy and suppress your cough.

A bronchoscope will be passed up through your nose or mouth, past your larynx (voice box), down your windpipe (trachea) and into your airways (bronchi). A soft plastic tube will be put inside your other nostril to give you some extra oxygen. An X-ray may be used to guide the bronchoscope. Your consultant may take a tissue sample to be examined (a biopsy).

The whole test usually takes around 15 to 20 minutes.

Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you and answer any questions you may have.

You shouldn't eat or drink for at least four hours before your bronchoscopy. Make sure you don't smoke immediately beforehand either. You'll need to organise someone to help you get home afterwards.

You should be able to go home a few hours after the test. Because your throat will be numb, you won't be able to eat or drink until your swallowing reflex returns to normal. You may have a slight nosebleed and, if you've had a biopsy, you may see a small amount of blood in your phlegm. This usually passes within 24 hours.

You may have a sore throat or a hoarse voice but this should also ease within a day or so. When you get home, it's important to rest for the remainder of the day. Sedation lasts longer than you think. For 24 hours after your test, you shouldn't drive a car, operate machinery or drink alcohol.
