EBUS and EBUS-TBNA are usually safe procedures. In a systematic review of effectiveness and safety, no serious complications were found for CP-EBUS-TBNA of regional lymph nodes. [33] Reported complications have included agitation, sore throat, cough, hypoxia, laryngeal injury, fever, bacteremia and infection, bleeding, pneumothorax, and broken equipment becoming stuck in the airway. Mediastinal abscess has also been reported. Complications related to upper airway local anesthesia are laryngospasm, laryngeal edema, bronchospasm, methemoglobinemia, and cardiac arrhythmias. [34] Complications attributable to procedural sedation are respiratory depression, cardiovascular instability, vomiting, and aspiration.

If the lung is punctured, an air leak (pneumothorax) can occur and cause collapse of the lung.

Following completion of the procedure, the bronchoscope should be disinfected and hung upright to prevent the accumulation of moisture.
