Bronchoscopy Safety in Patients With Chronic Obstructive Lung Disease

Area of Science:

• Pulmonology
• Respiratory Medicine
• Interventional Pulmonology

Background:

• Flexible bronchoscopy is a standard diagnostic procedure.
• Limited prospective data exist comparing outcomes in obstructive versus non-obstructive lung disease.

Purpose of the Study:

• To compare bronchoscopy complication rates in patients with and without chronic obstructive pulmonary disease (COPD).
• To assess the safety of moderate sedation flexible bronchoscopy in COPD patients.

Main Methods:

• Prospective study of 258 patients undergoing moderate sedation flexible bronchoscopy.
• COPD classification based on GOLD criteria using pulmonary function testing.
• Complication rates were compared between patients with and without COPD.

Main Results:

• Of 151 patients with PFTs, 67 had COPD (44%).
• Overall complication rates in COPD patients were 13% minor and 5% major.
• Respiratory complications were higher in severe/very severe COPD (22%) versus non-COPD patients (6%), even after adjustment.

Conclusions:

• Flexible bronchoscopy is safe for most COPD patients.
• Patients with severe to very severe COPD face increased respiratory complication risk.
• These risks warrant consideration during moderate sedation flexible bronchoscopy in severe COPD.
