Bronchial blocker positioning: learning curve and confidence in its use

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Medical Education

Background:

• The EZ blocker (EZB) is an underutilized yet safe and cost-effective device for one-lung ventilation.
• Underuse is attributed to the specialized skills required for correct placement and confirmation via fiber-bronchoscopy.

Purpose of the Study:

• To develop and evaluate an educational training program for novice anesthesiologists on the use of the EZ blocker (EZB).
• To determine the number of procedures necessary for skill acquisition in EZB placement and management.

Main Methods:

• The training program comprised three phases: a lecture, hands-on practice on a manikin, and supervised clinical application in thoracic surgery patients.
• Dexterity, confidence, and satisfaction levels were statistically assessed post-training.

Main Results:

• Significant improvement in EZB placement dexterity was observed after approximately six attempts.
• Skill acquisition for correcting EZB position was achieved within 15 attempts.
• Participants reported increased confidence and high satisfaction with the training program.

Conclusions:

• The EZ blocker is a valuable tool for achieving one-lung ventilation in thoracic surgery and should be part of every thoracic anesthesiologist's skillset.
• The developed teaching course provides an efficient and rapid method for training novice anesthesiologists in EZB utilization.
