Area of Science:

  • Veterinary Medicine
  • Surgical Techniques
  • Animal Research

Background:

  • Endotracheal intubation is crucial for mechanical ventilation in research animals.
  • Existing methods can be invasive and challenging, particularly for long-term applications.
  • Improving intubation techniques is essential for animal welfare and research accuracy.

Purpose of the Study:

  • To develop a simple, fast, reliable, and atraumatic method for endotracheal intubation in rats.
  • To facilitate long-term mechanical ventilation in rodent models.
  • To enable direct visualized placement of endotracheal tubes.

Main Methods:

  • A focused light source was used to transilluminate the neck region.
  • Light penetration through skin, muscles, and trachea was utilized.
  • Direct visualization guided the placement of an endotracheal tube.

Main Results:

  • The developed method proved to be simple, fast, reliable, and atraumatic.
  • Successful visualized endotracheal tube placement was achieved.
  • The technique is suitable for long-term mechanical ventilation in rats.

Conclusions:

  • This novel transillumination-guided intubation technique offers a significant advancement for rodent mechanical ventilation.
  • The method enhances animal welfare by minimizing trauma during intubation.
  • It provides a reliable and efficient approach for researchers requiring long-term respiratory support in rats.
