Innovative Pediatric Simulator for Difficult Airway Management Training.

Area of Science:

• Medical Simulation
• Pediatric Anesthesiology
• 3D Printing in Medicine

Background:

• Pediatric airway management poses unique challenges, especially in patients with congenital conditions.
• Existing pediatric mannequins often lack the pathological realism needed for effective training in difficult intubation scenarios.
• Crouzon syndrome is a congenital condition that can lead to difficult pediatric airway management.

Purpose of the Study:

• To develop and validate a high-fidelity, patient-specific pediatric airway mannequin.
• To simulate difficult intubation associated with Crouzon syndrome.
• To improve training for pediatric airway management.

Main Methods:

• Utilized CT and MRI scans of a 19-month-old patient with Crouzon syndrome for 3D modeling.
• Employed additive manufacturing (3D printing) for rigid components and silicone casting for soft tissues.
• Incorporated modular design with realistic anatomical features like a flexible tongue and movable jaw.
• Validated design through iterative testing and refinement.

Main Results:

• The simulator was evaluated during a pediatric bronchoscopy training course.
• Physicians reported strong agreement on the mannequin's effectiveness in replicating challenging intubation scenarios.
• The simulator demonstrated particular effectiveness for fiberoptic-guided intubation techniques.

Conclusions:

• A modular, patient-specific pediatric airway simulator offers a realistic, high-fidelity training platform.
• The anatomically accurate design enhances procedural confidence and skill acquisition for difficult intubation.
• This simulator is particularly beneficial for managing complex pediatric cases, such as those associated with Crouzon syndrome.
