Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopi…
Bronchoscopy is a diagnostic procedure that visualizes the larynx, trachea, and bronchi.
Diagnostic bronchoscopy enables the visualization and assessment of tissues, analysis of secretions, and collection of biopsy samples.
Therapeutic bronchoscopy eliminates obstructions, manages bleeding, treats atelectasis, removes lesions, and administers brachytherapy.
Pre-procedure nursing responsibilities include explaining the procedure, obtaining consent, and keeping the patient NPO for 6 hours.
Post-procedure, nurses should monitor vital signs and keep the patient NPO until the cough reflex returns.
Next, thoracoscopy is a diagnostic procedure to examine the pleural cavity by inserting an endoscope through small incisions.
It helps evaluate pleural effusions and tumors and collects fluid and tissue samples for diagnosis.
A chest tube may be inserted post-procedure for re-expansion of the lung.
Pre-procedure nursing responsibilities include obtaining consent and keeping the patient NPO.
Postoperatively, nurses must monitor vital signs, check the incision site for bleeding or infection, and monitor the chest tube and drainage system.

Q1: What structures does a bronchoscopy allow a nurse to visualize?
Bronchoscopy enables direct visualization of the larynx, trachea, and bronchi using a flexible fiber-optic or rigid bronchoscope. The fiber-optic bronchoscope is preferred due to its flexibility, small size, and excellent optical system, allowing increased visualization of peripheral airways. This visualization supports both diagnostic assessment and therapeutic interventions.
Q2: What are the main differences between diagnostic and therapeutic bronchoscopy?
Diagnostic bronchoscopy visualizes tissues, determines pathologic processes, collects secretions for analysis, and obtains tissue samples for diagnosis. Therapeutic bronchoscopy removes foreign bodies and secretions, controls bleeding, treats atelectasis, destroys lesions, provides brachytherapy, and inserts stents to relieve airway obstruction. Both procedures use the same equipment but serve distinct clinical purposes.
Q3: Why must patients remain NPO before bronchoscopy?
Patients must abstain from food and drink for at least 6 hours before bronchoscopy to decrease the risk of aspiration. After the procedure, patients should remain NPO until the cough reflex returns, ensuring airway protection during recovery. This precaution prevents aspiration of gastric contents during sedation and the procedure.
Q4: What post-procedure complications should nurses monitor for after bronchoscopy?
Nurses should monitor for hypoxia, hypotension, tachycardia, arrhythmias, hemoptysis, and dyspnea following bronchoscopy. Vital signs and respiratory status require continuous assessment, with abnormalities reported promptly. These complications can indicate adverse reactions to sedation, airway trauma, or bleeding during the procedure.
Q5: How does thoracoscopy differ from bronchoscopy in terms of procedure and access?
Thoracoscopy examines the pleural cavity by inserting an endoscope through small incisions in an intercostal space, whereas bronchoscopy visualizes airways through the nose, mouth, tracheostomy, or artificial airway. Thoracoscopy evaluates pleural effusions, tumors, and collects fluid and tissue samples. A chest tube may be inserted post-thoracoscopy for lung re-expansion.
Q6: What are the key post-operative nursing responsibilities after thoracoscopy?
Postoperatively, nurses must monitor vital signs, pain level, and respiratory status. The incisional site requires assessment for bleeding and infection. Shortness of breath may indicate pneumothorax and should be reported immediately. Chest tube monitoring and drainage system assessment are essential for proper lung re-expansion and patient safety.
Q7: What diagnostic purposes does thoracoscopy serve in respiratory assessment?
Thoracoscopy evaluates pleural effusions and pleural disease, stages tumors, and obtains fluid and tissue samples for analysis. If fluid is present, it is aspirated and sent for culture and sensitivity testing. Future applications include laser treatment of pulmonary nodules and other growths, making thoracoscopy valuable for comprehensive respiratory diagnosis.
