Single-use flexible bronchoscope evaluation for bronchoalveolar lavage

Area of Science:

• Pulmonology
• Medical Devices
• Endoscopy

Background:

• Single-use flexible bronchoscopes (SUFBs) have advanced significantly since 2009.
• Modern SUFBs now rival reusable flexible bronchoscopes (RFBs) in functionality.
• Despite advancements, SUFB performance and preference require continued evaluation.

Purpose of the Study:

• To assess and compare the performance and user preference of six leading SUFBs.
• To evaluate SUFB capabilities in simulated bronchoscopic procedures.

Main Methods:

• Thirty-one physicians performed simulated bronchoalveolar lavages (BALs) using six different SUFBs.
• Procedures were conducted on low-fidelity lung models.
• Physicians completed an 18-question survey using a five-point rating scale.

Main Results:

• The Ambu aScope 5 Broncho HD achieved the highest average scores for both performance (4.47) and sampling (4.40).
• Statistical analysis confirmed the Ambu aScope 5 HD's significantly superior performance and sampling scores compared to other SUFBs.
• All evaluated SUFBs exceeded a 'satisfactory' rating in performance and sampling.

Conclusions:

• The Ambu aScope 5 Broncho HD led in performance and sampling among the tested SUFBs.
• The Boston Scientific Exalt Model B and Ambu aScope 4 Broncho also showed strong performance and sampling results, respectively.
• Advancing SUFB technology is crucial for enhancing safety, performance, and convenience in bronchoscopy as procedure volumes increase.
