What Is Bronchoscopy?
Bronchoscopy is one of the most commonly performed lung procedures in India, and one of the most misunderstood. If your doctor has said the word to you in the last few days, you are probably picturing something more dramatic than it is. A camera. A tube. About 30 to 45 minutes of your time. That is more or less the whole thing.
I'm Dr. Kunal Waghray, Interventional Pulmonologist at Respire Airway Clinics, Hyderabad. I trained at the Amrita Institute of Medical Sciences in Kochi and run the bronchoscopy service here. The most common questions patients bring to a pre-procedure consultation are about pain, sedation, and what the doctor is actually going to see. This page answers those questions the way I would explain them sitting across from you.
A few things to know upfront. Bronchoscopy is not just a cancer test. In India it is performed at least as often for tuberculosis workup and unexplained cough as it is for malignancy. It does not involve general anaesthesia in the usual diagnostic case. You go home the same day. And the part that scares almost everyone, the idea of a scope passing into the throat, is almost entirely defused by a numbing spray that goes on before the scope does.
How It Works
A thin flexible tube with a camera on the end is passed into your airways. The doctor looks at them on a screen and, if needed, takes small samples. Three things happen in any standard bronchoscopy.
See your airways directly
Scans show shadows. The scope shows the actual lining: colour, swelling, narrowing, growths, sources of bleeding. There are things a CT cannot tell you that a bronchoscope can show in the first minute.
Sample tissue if needed
Through the scope, tiny brushes, a fine needle, or small biopsy forceps collect cells from a suspicious area. The lining of the airways does not carry pain fibres the way skin does. Sampling is not painful.
Treat certain problems
The same instrument can clear a mucus plug, remove an inhaled object, control bleeding, or place a stent in a narrowed airway. Most patients come for diagnosis, but therapeutic work uses the same scope.
Why Your Doctor Might Refer You
The honest list of reasons, more or less in order of how often they come up at our clinic.
A cough that has gone on for more than eight weeks and has not settled with usual treatments
Suspected pulmonary tuberculosis where sputum tests have come back negative or cannot be produced
Haemoptysis (coughing up blood), even small streaks that people sometimes brush off
An abnormal patch, nodule, mass, or area of collapse on a chest CT or X-ray that needs a closer look
Pneumonia that has not behaved the way it should, or that keeps coming back in the same area
Suspected interstitial lung disease, where a tissue sample is needed to make the diagnosis
Pre-treatment airway assessment for someone with a newly diagnosed lung cancer
Suspected sarcoidosis or other granulomatous disease where lymph node sampling is needed
If your doctor used the word EBUS or cryobiopsy, you are being referred for a specific kind of bronchoscopy. EBUS (endobronchial ultrasound) adds an ultrasound probe to sample lymph nodes just outside the airway wall. Cryobiopsy uses a small freezing probe to take a larger piece of lung tissue, mainly for suspected interstitial lung disease. Both use a bronchoscope. If persistent cough was what brought you here, that is one of the most common reasons for referral in India.
Flexible vs Rigid Bronchoscopy
Two main kinds exist. Almost everyone walking into a routine appointment is coming for the flexible kind.
Flexible Bronchoscopy
Thin, bendable, used under conscious sedation. The scope follows the natural curves of the airway and can reach further out into the smaller branches. This is the workhorse of diagnostic bronchoscopy.
Used for
- Seeing and sampling the airways
- Biopsy of suspicious lesions
- Bronchoalveolar lavage (BAL)
- EBUS and cryobiopsy in the same sitting
If your doctor has not used the word “rigid” specifically, this is what you are coming in for.
Rigid Bronchoscopy
A straight metal tube. Does not bend. Can only reach the central airways. Needs general anaesthesia and an operating theatre. Used mainly for therapeutic procedures.
Used for
- Removing inhaled foreign bodies
- Dilating a narrowed airway
- Placing an airway stent
- Controlling significant airway bleeding
What Happens During a Bronchoscopy
The procedure runs 20 to 45 minutes. Your total time at the clinic is closer to three to four hours, mostly preparation and recovery.
Arrive fasting
Nothing to eat for six hours beforehand, nothing to drink for the last two. You change into a gown. A nurse places a small IV cannula and attaches monitors: pulse oximeter, blood pressure cuff, ECG.
Throat numbing first
Before any scope goes near you, lignocaine (a local anaesthetic) is sprayed onto the back of your throat and through your nose. It tastes bitter for a few seconds. Within a minute the throat feels heavy and slightly distant. This switches off the gag reflex.
Conscious sedation
Midazolam plus fentanyl through the IV, titrated to your weight, age, and history. You keep breathing on your own. You are not unconscious. Most patients have no memory of the procedure afterwards even though they were technically awake.
The scope is passed
Gently through the nose, past the vocal cords, into the windpipe, and downwards. Pressure, not pain, is the sensation most patients describe if they remember anything at all. The camera image appears on the monitor next to me.
Airways are inspected and sampled
I look at the trachea, both main bronchi, and as far out into the smaller airways as the scope will reach. If your scan flagged a specific area, that is where I spend the most time. Samples are taken if needed.
Recovery
A nurse watches you for 30 to 60 minutes. Once you are alert, your throat numbness has worn off enough to swallow safely, and your observations are stable, you go home. A family member or arranged cab takes you.
Important: You cannot drive after the procedure due to sedation. Bring a family member or arrange a cab. Do not sign anything important on the same day.
Is Bronchoscopy Painful?
No. Bronchoscopy is not painful for most patients. This is the question that comes up more than any other in pre-procedure consultations, and the honest answer is that almost nobody describes it as painful afterwards.
What most patients remember: the bitter taste of the throat spray for a few seconds, a slow heavy calm settling in once the sedation goes through the IV, and then waking up in recovery wondering when the procedure is going to start. That strange gap is the amnesic effect of midazolam. It does not put you to sleep so much as stop your brain from laying down a memory of what happened.
A smaller number of patients do remember something, usually a feeling of pressure in the chest as the scope crosses the carina, or a brief urge to cough. Pain, in the sharp sense of the word, is rare.
Will I be awake?
Technically yes, under conscious sedation. Most patients describe it afterwards as a long heavy dream they cannot quite remember. If you are unusually anxious, general anaesthesia is worth discussing in your pre-procedure consultation.
What about the gag reflex?
The lignocaine spray turns off the gag reflex before the scope is anywhere near your throat. By the time the scope passes, the back of your throat does not register contact the way it ordinarily would.
For more detail on the procedure itself, see the bronchoscopy in Hyderabad page.
How to Prepare
Almost all preparation sits in the 24 hours before your appointment.
Fasting
No food for six hours beforehand. No fluids for two. Sips of water with essential morning medication are usually fine, but call the clinic the day before to confirm for your specific case.
Blood thinners
Aspirin, clopidogrel, warfarin, apixaban, rivaroxaban, dabigatran. Any of these needs a plan and most have to be paused for several days. Do not stop these on your own. Call the clinic so we can work it out with your cardiologist.
Diabetes medication
If you take insulin or oral hypoglycaemics, we will adjust your morning dose because you will be fasting through breakfast. Tell the nurse at the pre-procedure check.
Keep using your inhalers
Your regular asthma or COPD inhaler should be taken as usual on the morning of the procedure. Only blood thinners and diabetes doses need adjustment.
Bring someone to take you home
A relative, a friend, anyone who can sit beside you in a cab. You cannot drive, ride a two-wheeler, or travel home alone after sedation. This is non-negotiable.
Bring your scans and reports
CT, X-ray, blood work from the last three months, anything with your name and a date. These help me plan the procedure before you arrive in the suite.
If you develop a fever, new infection, or fresh chest pain in the days before your appointment: call the clinic before you set out. We will probably reschedule. Safer that way.
Recovery
You go home the same day. Most patients on the first morning slot are home before lunch.
First 2 hours
You wake up fully in the recovery bay. Your throat feels mildly numb. A small cough is normal. Both settle within an hour or two. No eating until the numbness wears off.
Hours 2 to 24
Sips of water first, then soft food. Avoid very hot food and drinks until the next day. Rest at home. No alcohol, no driving, no operating machinery.
Next day onwards
Most patients return to office work without much trouble. If your job is physical, give yourself an extra day. A mild sore throat and a small streak of blood in saliva for a day or two are normal.
Call us or go to emergency if any of these happen
- You cough up more than a teaspoon of fresh blood
- Temperature goes above 38 degrees Celsius and stays there for more than 12 hours
- Breathlessness gets worse rather than better
- Sharp chest pain that does not settle
For more on what to expect after the procedure, see the bronchoscopy in Hyderabad page.
Who Should Perform Your Bronchoscopy
Two bronchoscopies on a billing form look identical. Two bronchoscopies in real life, one done by a chest physician who performs the procedure occasionally and one done by an interventional pulmonologist who does it most days of the week, are not the same procedure.
Higher diagnostic yield
The biopsy is more likely to land in the right place. Samples are less likely to come back as insufficient material, which means a second procedure.
Sedation titrated to you
Dose is adjusted to the patient in real time rather than given as a fixed amount per kilogram off a sheet. This makes the experience smoother and recovery faster.
EBUS or cryobiopsy in the same sitting
If more than one procedure is needed, the operator can do it. You do not have to come back on a second day because the first operator does not have those skills.
Training at high-volume centres
Subspecialty training at the Amrita Institute means seeing unusual cases regularly rather than once a year. The European Diploma in Adult Respiratory Medicine (EDRM) on top of that.
If you have already been told you need a bronchoscopy, the page on bronchoscopy in Hyderabad walks through the procedure at our clinic in detail. If you are still earlier in the process, the page on what an interventional pulmonologist does covers the subspecialty.
Frequently Asked Questions
How long does a bronchoscopy take?
The procedure itself is 20 to 45 minutes. Your total time at the clinic, including preparation, sedation, and recovery, is closer to three to four hours. Most patients on the first morning slot are home before lunch.
Is bronchoscopy painful?
Most patients describe it as uncomfortable at most, and many remember almost nothing of it. The lignocaine throat spray switches off the gag reflex, the conscious sedation makes you drowsy and amnesic, and the lining of the airways does not carry pain fibres the way skin does. The most commonly reported sensation is brief pressure or a mild urge to cough.
Do they put you to sleep for a bronchoscopy?
For routine flexible bronchoscopy, no. You are given conscious sedation, which leaves you deeply relaxed, drowsy, and usually amnesic while you continue to breathe on your own. General anaesthesia is reserved for rigid bronchoscopy and more complex therapeutic procedures, and it is discussed with you in advance if it applies to your case.
What does a bronchoscopy diagnose?
Bronchoscopy is used for unexplained chronic cough, suspected tuberculosis with negative sputum, haemoptysis (coughing blood), abnormal findings on a chest CT or X-ray, recurrent or non-resolving pneumonia, suspected lung cancer, interstitial lung disease, sarcoidosis, and inhaled foreign bodies. In India, the most common indications are TB workup and unexplained cough, not cancer.
Why cannot a CT scan be used instead of bronchoscopy?
A CT scan shows the structure of the lung from the outside. It cannot show the colour of the airway lining, the source of bleeding, or sample tissue for laboratory testing. Many lung diseases require a tissue sample to confirm the diagnosis and guide treatment. A CT can tell us where to look. A bronchoscopy lets us look and sample.
Can I eat and drink before a bronchoscopy?
No food for six hours before the procedure. No fluids for two hours. Sips of water with essential morning medication are usually allowed, but check with the clinic the day before for your specific case.
What are the risks of bronchoscopy?
According to British Thoracic Society guidelines on diagnostic flexible bronchoscopy, serious complications occur in well under one to two percent of cases. The more common issues are minor bleeding from a biopsy site, a short dip in oxygen saturation during the procedure, a sore throat for a day or two, and a low-grade fever in the first 24 hours.
How long is recovery after a bronchoscopy?
You go home the same day. You can eat soft food about two hours after the procedure, once the throat numbness has worn off. No driving, alcohol, or machinery for 24 hours. Most patients return to office work the next day.
Does insurance cover bronchoscopy in India?
Most Indian health insurance and Mediclaim plans cover bronchoscopy when it is ordered by a doctor for diagnostic purposes. Whether the claim is cashless or by reimbursement depends on your particular policy and the network the hospital is in. The front office at Respire will verify your coverage with the insurer before the procedure date.
Have an unexplained cough, blood in your sputum, or an abnormal chest scan?
Book a consultation with Dr. Kunal Waghray at Respire Airway Clinics, Basheer Bagh or Jubilee Hills. The consultation covers your scans, your symptoms, and whether a bronchoscopy is actually the right next step.
