Fiberoptic Bronchoscopy in Paediatric Patients

Rigid and flexible fiberoptic bronchoscopy are two types of diagnostic and therapeutic procedures used in paediatric patients to examine and treat conditions affecting the airways. Both methods use a thin, flexible tube with a light and camera to visualise the airways.

The main difference between the two bronchoscopies lies in the flexibility of the scope. Rigid bronchoscopy utilises a rigid metal tube, allowing better control and manipulation within the airways. On the other hand, flexible bronchoscopy employs a flexible scope made of fiberoptic material, providing greater flexibility and access to smaller airways. These procedures are performed under general anaesthesia to ensure patient comfort and safety. Rigid and Flexible Fiberoptic Bronchoscopy offers a less invasive approach for visualising the airways and performing various treatment interventions.

Rigid and flexible fiberoptic bronchoscopy plays a crucial role in diagnosing and treating various respiratory conditions in paediatric patients, including: 

• The procedures allow physicians to visualise the airways directly, facilitating the identification of abnormalities such as tumours, strictures, or malformations within the airways. 
• Bronchoscopy provides a clear view of the airway anatomy, aiding in accurately diagnosing diseases such as asthma, bronchiolitis, pneumonia, or congenital abnormalities.
• Bronchoscopy can aid in evaluating recurrent respiratory infections, persistent cough, and unexplained breathing difficulties.
• Therapeutically, bronchoscopy removes foreign bodies, such as small toys or food particles, that can cause severe airway obstruction. 
• Bronchoscopy also enables the clearance of excessive mucus, facilitating better breathing and reducing the risk of infections. 
• Moreover, bronchoscopy can be used to biopsy suspicious lesions or administer medications directly to the affected areas.

Before a rigid or flexible fiberoptic bronchoscopy in paediatric patients, thorough preparation is essential to ensure a safe and successful procedure. It includes:

• Preoperative preparation: Preparation typically involves a comprehensive evaluation of the patient's medical history, physical examination, and review of any relevant imaging studies.
• Imaging: In some cases, the healthcare professional may perform blood tests, chest X-rays, or pulmonary function tests to provide additional information about the patient's respiratory health. 
• Pre-procedure instructions: To minimise the risk of complications during anaesthesia, the child will need to fast for several hours before the procedure. Parents or guardians will receive detailed instructions regarding the fasting period, medications, and any particular preparations that they must follow before the procedure. 
• Inform the healthcare team about any allergies or underlying medical conditions the child may have. This information will help ensure the safety and effectiveness of the procedure.

• Anaesthesia initiation: The paediatric patient will be under general anaesthesia to ensure comfort and prevent pain or discomfort during the procedure. The medical team will carefully monitor the child's vital signs throughout the bronchoscopy to ensure their safety.
• Bronchoscope insertion: A healthcare provider inserts a rigid metal tube through the mouth or nose into the airways for rigid bronchoscopy. The tube is gently advanced until it reaches the desired location within the airways, allowing visualisation and intervention as necessary. On the other hand, flexible bronchoscopy involves the insertion of a flexible fiberoptic scope through the nose or mouth into the airways.
• Airway evaluation: Once the scope is in place, the physician carefully manoeuvres the bronchoscope through the air passages to look for problems such as swelling, growths, things stuck in the airways, or structural abnormalities. 
• Treatment intervention: The healthcare provider will perform various therapeutic interventions depending on the findings. These may include removing foreign objects or excessive mucus, dilating narrowed airways, removing abnormal tissue growths, or administering medication directly to the affected area.

 If suspicious tissue growth or lesion is present in the airways, the doctor will take a biopsy (tissue sample) during bronchoscopy for further analysis.

After the bronchoscopy, the healthcare professionals remove the bronchoscope from the nose or mouth, and the medical staff closely monitors the child in a recovery area until the child has fully awakened from anaesthesia and their vital signs are stable. It is common for children to experience a sore throat or hoarseness after the procedure, which typically resolves within a few days.

The medical team may prescribe pain medications or recommend throat lozenges to alleviate discomfort. It is crucial to follow any post-procedure instructions the healthcare team provides, including restrictions on physical activity, diet, and medication usage.

Parents or guardians should closely observe the child for any signs of complications, such as persistent bleeding, worsening pain, difficulty breathing, or fever. If any concerning symptoms arise, it is essential to contact the healthcare team immediately for further evaluation and guidance.

Rigid and flexible fiberoptic bronchoscopy offers numerous benefits for paediatric patients, such as: 

• By providing direct visualisation of the airways, these procedures allow for accurate diagnosis and targeted treatment of various respiratory conditions. 
• The ability to take tissue samples during the procedure aids in identifying specific diseases and guides further management.
• Removing foreign bodies and clearing excessive mucus can quickly alleviate symptoms and prevent complications, such as recurrent infections or airway obstruction. 
• The ability to administer medications directly to the affected areas through bronchoscopy ensures targeted therapy and minimises systemic side effects.
• Bronchoscopy helps doctors to monitor the response to treatment and assess the progression of respiratory conditions over time. 
• The benefits of bronchoscopy extend beyond the immediate procedure. By identifying and treating underlying respiratory conditions, these procedures contribute to long-term respiratory health and improved quality of life for paediatric patients. 
• Regular follow-up and appropriate management based on bronchoscopy findings can prevent complications and optimise overall lung function.

While rigid and flexible fiberoptic bronchoscopy in paediatric patients is a safe procedure, some risks and potential complications need to be considered. These risks include bleeding, infection, adverse reactions to anaesthesia or medications, and injury to the airway or surrounding structures.

The risk of complications is typically low, and medical teams take extensive precautions to minimise these risks and ensure patient safety. However, parents or guardians must know the potential risks and discuss any concerns with the healthcare team before the procedure.

Rigid and flexible fiberoptic bronchoscopy in paediatric patients offers unique advantages over other diagnostic and therapeutic modalities. The direct visualisation of the airways allows for precise examination and intervention, leading to accurate diagnosis and targeted treatment.

The fiberoptic scope's flexibility in flexible bronchoscopy enables access to smaller airways, which may not be easily accessible with other techniques. This quality is beneficial in paediatric patients with complex airway anatomy or conditions affecting the smaller bronchi.

Furthermore, the ability to perform therapeutic interventions simultaneously with the diagnostic procedure eliminates the need for additional invasive procedures, reducing potential risks and improving patient outcomes. This comprehensive approach ensures that paediatric patients receive optimal care safely and efficiently.

What is fiberoptic bronchoscopy?

Fiberoptic bronchoscopy is a minimally invasive diagnostic and therapeutic procedure that allows for direct visualisation of the airways. It involves using a bronchoscope, a flexible, thin tube equipped with a camera and a light source at its tip. The device is carefully threaded through the nose or mouth, down the throat, and into the bronchial tubes.

The fiberoptic technology within the scope provides high-resolution images transmitted to a video monitor, allowing the medical team to observe the airway in real-time. It can also spot abnormalities, take tissue samples, and aid in performing specific treatments directly through the bronchoscope.

Why might a patient need a fiberoptic bronchoscopy?

Patients may need a fiberoptic bronchoscopy for various reasons. Common indications include persistent cough, unexplained shortness of breath, haemoptysis (coughing up blood), abnormal chest X-ray or CT scan results, and suspected lung infections or tumours. It's also a vital tool for evaluating chronic lung diseases such as COPD, asthma, and interstitial lung disease. Additionally, it can perform various therapeutic procedures, such as clearing airway obstructions, managing lung infections, or delivering medications directly to the lungs.

How is a fiberoptic bronchoscopy performed?

The performance of fiberoptic bronchoscopy requires careful preparation and skilled execution. Before starting, the patient is typically given a local anaesthetic or sedation to numb the throat and help relax. Healthcare professionals gently insert the rigid or flexible bronchoscope through the patient's nose or mouth, guiding it down the throat and into the airways. Bronchoscopy provides a clear view of the airway walls, branching patterns, and abnormalities. They can use small tools through the bronchoscope to take tissue samples or remove foreign materials if necessary.

Is fiberoptic bronchoscopy painful?

Due to the local anaesthetic and sedatives, most patients experience minimal discomfort during fiberoptic bronchoscopy. It's common to feel pressure or a slight urge to cough as the bronchoscope passes through the airways. There may be a sore throat or mild hoarseness post-procedure, but severe pain is rare.

What are the risks associated with fiberoptic bronchoscopy?

Fiberoptic bronchoscopy is generally safe when performed by experienced professionals, but there are some risks. These may include bleeding, especially if a biopsy is taken, infection, a reaction to the sedative, or a temporary drop in oxygen levels during the procedure. In rare cases, a pneumothorax (collapsed lung) or arrhythmias (irregular heartbeats) could occur.

How long does a fiberoptic bronchoscopy procedure take?

The length of the procedure can vary and mainly depends on its purpose and complexity. Typically, a diagnostic bronchoscopy may take between 30 to 60 minutes. If additional interventions are needed, such as biopsies or treatment of a lesion, the procedure may take longer. Including procedure preparation and recovery time, patients may spend a few hours at the healthcare facility.

Is sedation used during fiberoptic bronchoscopy?

Sedation is commonly used during fiberoptic bronchoscopy to ensure the patient is comfortable and to minimise coughing or gagging reflexes. Healthcare professionals may prefer the combination of a sedative and local anaesthesia. The level of sedation can range from mild, keeping the patient awake but relaxed, to deeper sedation, where the patient is in a sleep-like state but can still be awakened easily.

What should I expect during recovery after fiberoptic bronchoscopy?

Immediately after the bronchoscopy, the medical team will monitor patients as the sedative wears off. It's normal to feel groggy or sleepy for a few hours. A sore throat, cough, or hoarseness can occur but typically resolves within a day or two. Healthcare professionals usually advise patients to rest for the rest of the day and avoid driving or operating heavy machinery.

How long does it take to recover from fiberoptic bronchoscopy?

Recovery times can vary, but most patients return to normal within 24 hours. If healthcare providers perform a biopsy or other interventions, there might be specific post-procedure instructions to follow. It's essential to report any unusual symptoms, such as fever, chest pain, or difficulty breathing, to a healthcare provider immediately.

Are there any dietary restrictions before a fiberoptic bronchoscopy?

Patients are generally instructed to avoid drinking or eating for a few hours before the procedure to reduce the risk of aspiration. The exact time frame can vary, but a common guideline is nothing by mouth for at least 6 to 8 hours before fiberoptic bronchoscopy.

Can I drive myself home after a fiberoptic bronchoscopy?

Due to the sedatives used during the procedure, it is not safe to drive immediately afterwards. You will need someone to drive you home, and having a responsible adult stay with you for at least the first few hours post-procedure is advisable.

How often are fiberoptic bronchoscopy procedures performed?

The frequency of fiberoptic bronchoscopy procedures depends on the indication for the exam and the findings of the initial procedure.
