What is flexible bronchoscopy?

Paediatric flexible bronchoscopy - sometimes searched as bronchoscopy in children or bronchoscopy in infants - is a minimally invasive diagnostic and therapeutic procedure using a thin, flexible tube with a camera (bronchoscope) to view a child’s airways. It allows real-time visualization from the nose and throat down into the trachea and bronchi, enabling detailed assessment of airway anatomy and function.

Which airway areas can flexible bronchoscopy examine in children?

Flexible bronchoscopy visualizes:

• Nose and nasal passages
• Back of the nose and throat (nasopharynx)
• Larynx (voice box) and vocal cords
• Trachea (windpipe)
• Bronchi (airway branches in the lungs)

The procedure evaluates airway structure, observes any obstruction, inflammation, anatomic abnormalities, or presence of foreign bodies.

When is flexible bronchoscopy indicated in paediatric and neonatal patients?

Common clinical situations requiring flexible bronchoscopy include:

• Noisy breathing or stridor without clear cause
• Persistent or recurrent pneumonia
• Repeated episodes of wheezing not responding to standard treatment
• Chronic or unexplained cough
• Suspected foreign body aspiration
• Evaluation of suspected congenital airway abnormalities such as tracheomalacia or bronchomalacia
• Investigations in children with suspected or persistent tuberculosis
• Assessment of respiratory complications in immunocompromised children

In premature and newborn babies, neonatal bronchoscopy is most often used to investigate noisy breathing, feeding-related breathing difficulty, or airway problems that appear after birth - including in babies who need prolonged breathing support in the neonatal intensive care unit.

How should children be prepared for flexible bronchoscopy?

Proper preparation helps ensure safety and success:

• Medical history review and physical examination by the pediatric pulmonologist
• Fasting before the procedure to reduce the risk of aspiration. Timing depends on what your child last ate or drank: typically 2 hours for clear fluids, 4 hours for breast milk, and 6 hours for formula, other milk or a light meal. Your care team will confirm exact timings for your child's age and the sedation plan.
• Sedation or general anesthesia is planned based on age, condition, and procedure complexity
• Intravenous access (IV line) is established for medications and anesthesia
• Parents will be counseled about the procedure, possible risks, and post-procedure care

How is flexible bronchoscopy performed safely for paediatric patients?

• The bronchoscope is gently inserted through the child’s nose (or mouth if necessary) and advanced carefully into the airways under sedation or anesthesia. For bronchoscopy in infants and very young babies, a narrower, infant-sized bronchoscope is used to suit the smaller airway; the same safety principles apply at every age.
• High-quality video images enable detailed airway examination.
• Bronchoalveolar lavage (BAL), the collection of fluid samples from lungs, may be performed when infections or other diseases are suspected.
• The procedure lasts approximately 10-15 minutes; monitoring is continual for oxygen levels, heart rate, and comfort.
• Interventions such as suctioning mucus, foreign body removal, or biopsies can be performed during the procedure if indicated.

What are the risks and possible complications of flexible bronchoscopy in children?

While generally safe, potential complications include:

• Transient oxygen desaturation (low blood oxygen), usually manageable and temporary
• Minor nosebleeds
• Mild throat discomfort or hoarseness after the procedure
• Rarely, laryngospasm, bronchospasm, or apnea may occur, requiring immediate medical intervention
• Serious complications like pneumothorax (collapsed lung) are very rare

A large prospective study of over 1,300 paediatric flexible bronchoscopies recorded at least one complication in about 7 in 100 procedures — most were minor and temporary (brief desaturation, mild coughing, a nosebleed). Complications needing active treatment occurred in fewer than 2 in 100 procedures, and pneumothorax occurred in roughly 1 in 1,300 procedures. Children under 2 years old and those with an existing airway abnormality carry a somewhat higher chance of a breathing-related complication during the procedure, which is why continuous monitoring is used throughout.

Careful monitoring by an experienced pediatric bronchoscopy team helps identify and manage these events quickly if they occur.

What can parents expect after the procedure?

• After bronchoscopy, your child’s health will be observed in a recovery area until the effects of sedation wear off - typically within 1 to 3 hours, depending on the type and depth of sedation used, until they are fully awake, breathing comfortably, and able to take fluids.
• Oral feeding can resume once medically cleared.
• Mild throat discomfort or cough may occur but typically resolves quickly.
• Most children resume normal activities within a day.
• The pulmonologist will discuss findings and treatment plans based on bronchoscopy results.

Frequently Asked Questions

1. Is flexible bronchoscopy safe for children?

Yes, it is a safe, minimally invasive procedure when conducted by experienced pediatric pulmonologists using sedation or anesthesia to ensure comfort.

2. How long does the procedure take?

Typically 10-15 minutes, with total time (including preparation and recovery) lasting 1-2 hours.

3. What are the potential risks?

Complications are rare, including transient oxygen desaturation, mild nasal bleeding, or throat discomfort. All risks are closely monitored and managed.

4. How soon can my child resume normal activities?

Most children return to usual activities within 24 hours after bronchoscopy.

5. Is the procedure painful?

No, sedation or anesthesia ensures the procedure is painless and comfortable.

6. Is bronchoscopy for a baby different from bronchoscopy in older children?

The procedure and its goals are the same, but babies need a narrower bronchoscope sized for their smaller airway, and closer monitoring - infants under 2 years old have a somewhat higher chance of a brief oxygen dip during the procedure, so extra caution and continuous monitoring are standard practice at this age.

7. Can flexible bronchoscopy be performed on premature or very small newborns?

Yes. Advances in smaller-diameter bronchoscopes and anaesthetic technique have made it possible to safely perform bronchoscopy even in very small, unwell infants, provided the right precautions and an experienced team are in place.

8. How is bronchoscopy different from a chest X-ray or CT scan for my child's breathing problem?

X-rays and CT scans show the structure of the lungs and airways from the outside, while bronchoscopy lets the doctor see directly inside the airway and, if needed, collect fluid or tissue samples or remove an obstruction in the same sitting. Bronchoscopy is often used when imaging doesn't fully explain the symptoms, or when a direct sample is needed for diagnosis.

9. Can a foreign body be removed during the same bronchoscopy session if one is found?

Yes - foreign body removal is one of the most established therapeutic uses of flexible bronchoscopy in children, alongside suctioning and other interventional techniques performed during the same procedure.
