Nursing care
Bronchoscopy: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Bronchoscopy nursing management centres on airway protection before and after the scope: confirm consent and NPO status pre-procedure, monitor sedation and oxygenation during, and keep the patient nil by mouth afterward until the gag reflex returns, since eating or drinking too soon risks aspiration.
Indications and contraindications
Bronchoscopy is ordered to visualise the airway directly, obtain tissue or lavage samples, remove a foreign body or mucus plug, or place a stent. It is used both diagnostically, for unexplained haemoptysis or a suspicious mass on imaging, and therapeutically, for airway clearance in a patient who cannot mobilise secretions. Flexible bronchoscopy is the usual bedside or outpatient approach; rigid bronchoscopy is reserved for major bleeding, large foreign bodies, or extensive airway obstruction and needs a controlled operating room setting.
Absolute and relative contraindications matter for your pre-procedure check. Severe hypoxaemia that cannot be corrected, an unstable cardiac rhythm, and an uncorrected bleeding disorder all raise the risk of the procedure outweighing its benefit. Recent myocardial infarction, severe pulmonary hypertension, and a platelet count too low for safe biopsy are relative contraindications the proceduralist weighs against urgency. Flag any anticoagulant or antiplatelet medication in the chart before the list is confirmed, since biopsy plans change accordingly.
Getting the patient ready
Confirm signed consent, verify the patient understands the procedure in their own words, and check that NPO status has been maintained for six to eight hours to reduce aspiration risk during sedation. Establish IV access, obtain baseline vital signs and oxygen saturation, and review recent coagulation studies and platelet count if biopsy is planned. Remove dentures and any oral appliances, and ask about allergies to local anaesthetics such as lidocaine, which is sprayed onto the oropharynx before the scope passes.
Explain what the patient will feel: pressure rather than pain, a strong urge to cough, and a sensation of breathlessness that is normal and monitored throughout. Position the patient supine or semi-Fowler's for the procedure, and have suction, supplemental oxygen, and emergency airway equipment at the bedside before the operator begins. A baseline ECG and pulse oximetry reading should be documented, since these values are your reference point for detecting deterioration once sedation starts.
Technique and safety checks
The bronchoscope passes through the nose or mouth, or through an existing endotracheal or tracheostomy tube in a ventilated patient. Topical anaesthetic numbs the pharynx and vocal cords first, and moderate sedation, commonly midazolam with fentanyl, is titrated to keep the patient cooperative but breathing spontaneously. Continuous pulse oximetry and cardiac monitoring run throughout, and capnography is used where available to catch hypoventilation before saturation drops.
Your role during the procedure is vigilance, not just documentation. Watch for a falling saturation, a new arrhythmia, or laryngospasm, and have the operator pause if the patient becomes agitated or the airway looks compromised on the monitor. Keep a running count of lidocaine dose administered, since topical anaesthetic absorbed across the airway mucosa can reach toxic levels and cause seizures or cardiac effects if the ceiling dose is exceeded.
What can go wrong
The complication nurses are taught to anticipate first is aspiration, and it happens when oral intake resumes before protective airway reflexes have returned. The gag reflex, and swallowing coordination generally, stay suppressed for one to two hours after topical anaesthesia, so the patient must remain nil by mouth until the gag reflex is confirmed present on direct testing, not simply because time has passed.
Bleeding after biopsy is usually minor and self-limiting, but watch for frank haemoptysis beyond a few streaks of blood-tinged sputum. Pneumothorax is a recognised risk after transbronchial biopsy, presenting as sudden chest pain, dyspnoea, or absent breath sounds on one side, and it warrants an urgent chest X-ray. Laryngospasm or bronchospasm can occur during or immediately after the scope, and fever within 24 hours, sometimes called post-bronchoscopy fever, is common after bronchoalveolar lavage and is usually self-limiting rather than infective.
Ongoing care
Once the scope is withdrawn, keep the patient on continuous pulse oximetry and monitor respiratory rate and effort until sedation has fully worn off. Test the gag reflex before offering anything by mouth: touch the posterior pharynx gently or observe the patient swallow saliva without difficulty. Start with sips of water once the reflex is confirmed, and only progress to a normal diet once that trial succeeds without coughing or choking.
Monitor for delayed bleeding, worsening dyspnoea, or chest pain over the following hours, and auscultate breath sounds bilaterally if biopsy was performed, since a developing pneumothorax may not be obvious immediately. Document the return of the gag reflex, the time oral intake resumed, and any blood-tinged sputum, since blood streaking that persists or increases needs escalation rather than reassurance.
Common exam questions
NCLEX-style questions on bronchoscopy usually test the sequence of safe post-procedure care rather than the procedure itself. Expect a scenario where a patient asks for water immediately after returning from bronchoscopy, and the correct action is to withhold oral intake and check the gag reflex first, not to simply wait a fixed number of hours.
Other questions test recognition of complications: a patient who develops sudden sharp chest pain and shortness of breath after biopsy points to pneumothorax, while frank red blood in large volume points to significant post-biopsy bleeding rather than expected blood streaking. You may also see questions on lidocaine toxicity, where a patient becomes confused or has perioral tingling during the procedure, which should prompt the nurse to notify the proceduralist and track total anaesthetic dose given.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our respiratory practice questions are the closest set to what this page covers.
Common questions
How long is a patient NPO after bronchoscopy?
There is no fixed number of hours. The patient stays nil by mouth until the gag reflex is confirmed to have returned, which is usually one to two hours after topical anaesthesia but should always be tested directly rather than assumed from a clock.
Can a patient talk right after bronchoscopy?
Expect a hoarse voice and mild sore throat from the local anaesthetic and scope passage, which usually settles within a day. Persistent voice change or stridor should be reported, as it can signal vocal cord irritation or swelling.
What vital sign change signals a complication after bronchoscopy?
A falling oxygen saturation, new tachypnoea, or asymmetric breath sounds after biopsy should raise suspicion for pneumothorax and prompt urgent reassessment and likely a chest X-ray.
Is a small amount of blood in sputum after bronchoscopy normal?
Yes, blood-tinged sputum for a few hours after biopsy is expected. Frank haemoptysis, increasing blood volume, or bleeding that does not settle needs escalation to the medical team.
Why does bronchoscopy cause a fever?
Post-bronchoscopy fever, particularly after bronchoalveolar lavage, is common within the first 24 hours and is usually a self-limiting inflammatory response rather than infection. Persistent or high fever should still be evaluated to rule out post-procedure pneumonia.
