Area of Science:
- Medical Devices
- 3D Printing Technology
- Anesthesiology
Background:
- The COVID-19 pandemic has strained global healthcare systems, increasing the need for critical respiratory support.
- Tracheal intubation, often requiring a video laryngoscope, is a key procedure for patients needing ventilation.
- Limited availability and high cost of conventional video laryngoscopes hinder widespread access in healthcare settings.
Purpose of the Study:
- To develop and validate a novel, low-cost 3D-printed video laryngoscope.
- To create pediatric and adult versions of the 3D-printed laryngoscope.
- To ensure the efficiency, reproducibility, and safety of the 3D-printed device.
Main Methods:
- A novel video laryngoscope model was designed with pediatric and adult versions.
- Prototypes were manufactured using 3D printing techniques.
- Mechanical assays were conducted to evaluate the prototypes' performance and safety.
Main Results:
- The 3D-printed laryngoscope prototypes demonstrated satisfactory mechanical performance.
- Evaluation indicated a sufficient safety factor for clinical use.
- The developed models offer versions suitable for both pediatric and adult patients.
Conclusions:
- The novel 3D-printed video laryngoscope presents a cost-effective and accessible alternative to conventional devices.

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
17
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...

01:25Suctioning the Oropharyngeal Airway
232
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:23Oxygen Delivering System III: Tracheostomy and T-piece
1.1K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

01:28Tracheostomy: Procedure and Tubes
668
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...
