A Pilot Study of Simulation Training in Difficult Bag Mask Ventilation Using a Computerized Patient Simulator

Area of Science:

• Medical Education
• Anesthesiology
• Emergency Medicine

Background:

• Bag mask ventilation (BMV) is a critical skill in airway management.
• Simulation is recognized as an effective training tool, but its efficacy for challenging BMV scenarios requires further investigation.

Purpose of the Study:

• To compare the effectiveness of simulation-based training versus on-patient training for difficult bag mask ventilation.
• To evaluate the impact of training modality on post-test pass rates in a patient setting.

Main Methods:

• A pilot study randomized 32 medical students to receive difficult BMV training on either simulators or patients.
• Pre- and post-training assessments were conducted on both simulators and patients, alongside confidence surveys.
• The primary outcome was the difference in patient post-test pass rates, with a 10% improvement considered significant.

Main Results:

• Students trained on simulators demonstrated a 13% higher pass rate on the patient post-test (88% vs. 75%).
• Passing the simulator post-test was associated with an 11-fold increased odds of passing the patient post-test (P=0.023).
• Higher post-training confidence was reported by participants who passed simulator assessments and received simulator training.

Conclusions:

• Simulation-based training for difficult BMV yielded superior patient test performance compared to traditional on-patient training.
• Successful completion of difficult BMV simulation correlates with improved performance in real-patient scenarios.
• Further validation in larger randomized controlled trials is warranted to confirm these findings.
