Summary
A new synthetic simulator for tracheostomy and laryngotracheal reconstruction (LTR) surgery demonstrates high realism and effectiveness. This training tool was found to be comparable to live porcine models for teaching these complex airway procedures.
Area of Science:
- Surgical Education
- Medical Simulation
- Anatomical Modeling
Background:
- Tracheostomy and laryngotracheal reconstruction (LTR) are critical surgical procedures.
- Effective training methods are essential for developing proficiency in these techniques.
- Current simulation models may not fully replicate the complexities of these surgeries.
Purpose of the Study:
- To develop and validate a novel synthetic simulator for teaching tracheostomy and LTR.
- To assess the simulator's face and content validity using expert otolaryngologists.
- To compare the simulator's performance against a live porcine model.
Main Methods:
- A synthetic neck and airway simulator was created using 3D printing from CT scans.
- Expert surgeons performed tracheostomy and LTR on both the synthetic simulator and a live porcine model.
- Simulator validity was assessed using a 5-point Likert scale for realism and training effectiveness.
Main Results:
- Expert surgeons rated the synthetic simulator highly for face (median 4) and content validity (median 5).
- No significant differences were found in surgical procedure outcomes between the synthetic simulator and the live porcine model.
- The simulator accurately replicated anatomical structures for tracheostomy and LTR.
Conclusions:
- The developed synthetic simulator possesses high face and content validity for tracheostomy and LTR.
- It serves as a valuable and effective training tool, comparable to live animal models.
- This simulator offers a reproducible and accessible method for surgical skills development.

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
271
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.

01:28Tracheostomy: Procedure and Tubes
1.9K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
