Before you read on: This is patient education, not a replacement for the doctor running your case. Your plan depends on your CT scan, your history, and which lymph nodes the team is sampling. The discharge sheet you receive on the day always overrides anything you read on the internet, including this page.
EBUS: What to Expect on the Day of Your Procedure
Written by Dr. Kunal Waghray, MD DM DNB MNAMS EDRM, Interventional Pulmonologist, Respire Airway Clinics, Hyderabad. Last reviewed 13 May 2026.
Almost everyone reaches this page the same way. A sentence got said in a consulting room. "There's a shadow in the mediastinum on your CT. We'd like to do an EBUS, biopsy the lymph nodes." Then it's Thursday night, the slot is Friday at 8.30am, and the family WhatsApp is doing laps at a higher pitch than usual.
Dr. Kunal Waghray here. EBUS-TBNA is most of a Tuesday and a Friday for me, at Basheer Bagh and at Jubilee Hills both. What follows is the version of the morning I would talk through if my own cousin were on tomorrow's list.
For those reading this at 1am: empty stomach six hours, no water two hours, loose clothes, named adult driver, arrive on time, gown on, IV in, throat numbed, deeper sedation than a regular bronchoscopy, thirty to sixty minutes of scope, three to five needle passes per node, an hour or so in recovery, soft food at home, no alcohol, voice husky for a day, a result conversation in roughly two weeks. The rest of the page is that, slowed down. For background on what EBUS is at a procedural level, the education page covers the mechanism in more depth.
Why This Morning Feels Different from a Normal Bronchoscopy
A standard flexible bronchoscope is roughly the width of a pencil. An EBUS scope is closer to the width of an adult little finger. There is a real-time ultrasound transducer built into the tip, which is what lets us see through the airway wall and find the lymph node sitting on the other side of it.
That extra thickness is the reason EBUS sedation runs deeper. A normal diagnostic bronchoscopy can be done with light conscious sedation in fifteen to thirty minutes. EBUS asks more of the throat, and asks the patient to lie still while several needle passes are made into a precise spot, so we go deeper on the drugs and slower on the scope.
The other quiet difference: the result. A standard bronchoscopy with washings and brushings often gives a preliminary read inside a week. EBUS lymph node samples go to cytology first, then to a histology block, then to a multidisciplinary team meeting. Seven to fourteen days is the honest window in Hyderabad. The result does not come back on the day.
The Night Before and the Morning Of
Fasting
Nothing solid for six hours before your slot. No water for the last two. Coffee, tea, juice, chai, even chewing gum sit in the same category.
Regular medicines
Take them in the morning with a tiny sip of water, unless told otherwise. Blood thinners, diabetes tablets, and insulin are the three we usually adjust. If you are on any of those and we have not specifically called you, ring the clinic before you leave the house.
Wear loose
A cotton kurta, a salwar kameez, a buttoned shirt that opens at the front. The IV goes into the back of your hand, so tight sleeves are a nuisance. Leave watches, bangles, and contact lenses at home.
Driver
An adult driver must come with you. EBUS sedation blunts reaction time for the rest of the day even after you feel sharp. We have turned patients away at the door for arriving without a named driver.
Arriving at the Clinic and Meeting the Team
You walk in, give your name and appointment letter to reception, and they confirm your fasting hours one more time. Our EBUS lists usually run between 8am and 11am, so the waiting area is calm.
A nurse takes you through to the changing room. Gown over your underwear, clothes and bag locked in a small cupboard, key on a wristband that stays with you. Family settles in the lobby.
From there it is a short walk to the EBUS procedure room. The room is quieter than people expect. There is a bed tilted slightly head-up, two monitor screens (one for the heart trace, oxygen, and blood pressure; one for the live ultrasound image), a draped trolley with the convex probe EBUS scope on it, and three or four team members getting set.
The next ten minutes are paperwork and physical checks. We re-read the consent form with you line by line. Stethoscope on the chest. Pulse oximeter clip on a finger. Blood pressure cuff on the other arm. Three small electrode dots on the chest for the heart trace. None of this hurts.
The Numbing, the IV, and the Sedation
The cannula goes in first. A nurse cleans the back of one hand with an alcohol swab, the needle goes in, the metal slides out, a thin plastic line stays behind. Brief sting and done.
Then the lignocaine throat spray. A 2% solution, the same family of drug as the local injection a dentist uses, delivered as a fine mist. Two or three short puffs onto the back of the tongue and into the throat. The taste is bitter and a little chemical. Within a minute the back of the throat feels heavy and somehow far away. Patients describe it as "overcooked banana" or "cough syrup with the sugar scraped off."
Then the sedation. Through the cannula, midazolam goes in first, usually with a small dose of fentanyl alongside to settle the cough reflex. EBUS sedation runs deeper than a routine bronchoscopy. Patients describe the midazolam as a warm wave that climbs up the arm, then the shoulders, then the room going a bit softer at the edges. You stay breathing on your own throughout. But the next thirty to sixty minutes will be largely missing from your memory afterwards, and that absence is the entire point of the drug.
Inside the Procedure Room: Ultrasound and Needle Passes
You are lying back at about thirty degrees, oxygen running quietly through a soft nasal prong. The scope goes in through the mouth, past the back of the tongue, gently over the vocal cords. A short cough at the cords is normal, and a little more lignocaine is dripped through the scope channel right then if it happens.
Now the ultrasound work begins. The transducer at the tip is pressed gently against the inside wall of the airway, and the screen shows a grey-and-black ultrasound image of the lymph node sitting on the other side of the wall. A thin needle, hollow, slides out from the side of the scope, through the airway wall, into the node. Suction is applied. A small sample of cells comes back inside the needle. The needle withdraws. That is one pass. Most lymph node stations need three to five passes for an adequate sample.
None of this is felt. The lining of the airway has almost no pain nerves. What patients sometimes register, dimly, is pressure, the way you might feel a hand pressed on your chest through a blanket while you are half-asleep. Pressure, not pain.
From scope in to scope out is usually thirty to sixty minutes for our EBUS in Hyderabad cases, with three to five lymph node stations sampled. The scope comes out the way it went in, slowly.
Recovery and Going Home
You are wheeled, still on the same bed, to a quieter recovery bay. The pulse oximeter clip stays on your finger. Lights are softer. A recovery nurse sits close, with a watchful eye on the monitor.
First forty-five minutes to an hour is the part where the sedation wears off. Almost every clinic morning, a patient opens their eyes, looks at the nurse, and asks with complete sincerity, "When are we going to do it?" The procedure has been over for thirty minutes. They will not remember the conversation later.
Around the hour mark, most patients are sharp again. The nurse offers a small sip of plain water. If it goes down cleanly, you are cleared for a soft snack a little later: curd rice, dal, khichdi, an idli soaked in sambar until the edges go soft. Save the very spicy food and the very hot chai for tomorrow.
I come round to talk before discharge papers are signed. What I can tell you on the day is what we saw on the screen: the ultrasound image of each node, the number of passes, whether the samples looked cellular. What I cannot tell you on the day is what the cells actually are. That comes from the lab. We will already have booked your result visit before you leave.
Waiting for the Result: the 7 to 14 Day Window
This is the section nobody else writes, and the one I get asked about most often after the procedure is done.
The samples your EBUS produces go through three stages before anyone calls you with a result. First, the needle aspirate goes to the cytology lab, where a pathologist looks at the cells directly under a microscope. That read is usually back inside four to seven working days in Hyderabad. Second, the small core of tissue, if one was retrieved, goes for histology with special stains, which can take seven to ten working days. Third, the case is presented at a multidisciplinary team meeting, the MDT, where pathologists, radiologists, oncologists, surgeons, and pulmonologists look at the images and the slides together.
Seven to fourteen days is the honest window from procedure to a sit-down conversation. We tell you the truthful range, not the optimistic one.
On the forum-reading temptation
The temptation in the wait is to search a phrase from your CT report, end up on a forum, then on a Reddit thread from 2019 about somebody else's lymph node biopsy in another country. The boring outcomes, sarcoidosis, reactive nodes, a stable benign finding, do not get Reddit posts. Your result will be your result.
Your result visit was booked before you left the recovery bay. You have a date and a time. If anxiety in the wait is sharp enough to disrupt sleep or appetite, that is worth a phone call too.
What to Tell Your Family the Day Before
Tell them four hours, not the forty-five minutes of the scope. Most of the time is preparation, recovery, and the post-procedure conversation. Ask them to bring a charger, a book, and lunch money.
Tell them they cannot drive you home with their other hand on a work call. EBUS sedation lasts longer than for a routine bronchoscopy. If they have an unmissable meeting at noon, find a different driver.
Tell them they will be allowed into the recovery bay once you are awake, usually about an hour after the scope comes out. If a nurse says "another twenty minutes" when they ask, that is the normal answer, not bad news.
And tell them, kindly, not to be alarmed if you ask the same question three times in the first ten minutes after waking. Midazolam has that effect. Most families end up laughing about this at dinner.
Frequently Asked Questions
What should I expect during an EBUS procedure?
An empty-stomach arrival, a gown, an IV, throat numbed with lignocaine spray, sedation through the IV, a thirty-to-sixty-minute procedure where a thicker scope with an ultrasound on the tip samples lymph nodes through the airway wall, then an hour or so in recovery before you go home. Most patients remember very little of the procedure itself.
How long does an EBUS procedure take?
The scope is inside you for thirty to sixty minutes for most cases, occasionally up to seventy minutes when multiple lymph node stations are sampled. Total clinic time, including preparation and recovery, is around three to four hours.
Are you awake during an EBUS?
Technically yes, under deep conscious sedation. In practice almost nobody remembers the procedure. The midazolam and fentanyl combination used has an amnestic effect, so the thirty to sixty minutes of scope time are largely missing from memory.
How do I prepare for an EBUS?
Stop solid food six hours before your slot, stop water two hours before, wear loose clothes that open at the front, leave watches and jewellery at home, bring your reports and a phone charger, take your usual morning medicines with a tiny sip of water unless told otherwise, and arrange a named adult driver for the trip home.
Is EBUS more painful than a regular bronchoscopy?
It is not more painful. The scope is thicker and the procedure is longer, so a deeper level of sedation is used to keep you comfortable. The airway lining and the lymph nodes themselves have almost no pain nerves. Most patients describe pressure rather than pain when they remember anything at all.
How long does it take to get EBUS results?
Seven to fourteen days, honestly. Cytology comes back inside four to seven working days, histology inside seven to ten, and the case is then reviewed at a multidisciplinary team meeting. Your result visit is booked before you leave the recovery bay on the day of the procedure.
How long do you stay in hospital after EBUS?
Most patients are discharged two to three hours after arrival. Overnight stays are rare for a routine diagnostic EBUS.
When can I eat after EBUS?
A small sip of plain water about an hour after the procedure, once the recovery nurse has cleared you. Soft food a little later: curd rice, dal, khichdi, soaked idli. Save spicy food and very hot drinks for the next day.
Can I go to work the day after EBUS?
For desk work, usually yes, with a slightly husky voice for the first few hours. For physical or heavy work, wait forty-eight hours. Do not drive for twenty-four hours after the procedure.
What are the risks of EBUS?
EBUS-TBNA is a very safe procedure. The recognised risks, all uncommon, include a sore throat, a small amount of blood-streaked sputum for a day, a low-grade fever in the first twenty-four hours, and very rarely bleeding from a node site, a chest infection, or a small pneumothorax.
Book a Pre-EBUS Consultation
Most of the anxiety on the morning of an EBUS comes from never having walked the morning before. A pre-procedure consultation with Dr. Kunal Waghray fixes that. Sit across the table, see your CT scan on screen, and have the morning of the procedure stop being a stranger. Available at our Basheer Bagh and Jubilee Hills clinics. For the wider context on what an interventional pulmonologist in Hyderabad does, the hub page covers our scope of practice in full.
