Flexible fiberoptic bronchoscopy. Anesthesia, technique and results

Area of Science:

• Pulmonology
• Medical Procedures

Background:

• Diagnostic bronchoscopy is a key procedure in respiratory medicine.
• Evaluating peripheral lung lesions presents diagnostic challenges.

Purpose of the Study:

• To assess the efficacy and safety of flexible fiberoptic bronchoscopy for diagnosing lung conditions.
• To determine the optimal route and guidance for bronchoscopy.

Main Methods:

• A retrospective review of 256 diagnostic bronchoscopies performed over three years.
• Utilized flexible fiberoptic bronchoscopes with topical cocaine hydrochloride anesthesia.
• Employed the peroral route with an endotracheal tube and fluoroscopic guidance.

Main Results:

• Topical cocaine hydrochloride anesthesia was satisfactory and safe.
• Fluoroscopic guidance was crucial for examining peripheral lung lesions.
• Achieved a 70% positive yield for peripheral lung carcinoma with guided biopsies versus 47% for blind biopsies.

Conclusions:

• Flexible bronchoscopy is a valuable diagnostic tool for peripheral lung lesions.
• The peroral route and fluoroscopic guidance enhance diagnostic yield.
• Cocaine hydrochloride anesthesia is a safe and effective option for bronchoscopy.
