简介：
Overview
This protocol presents a method for visualizing the glottis and achieving rapid intubation in mice with minimal tissue trauma. The technique utilizes a camera-based otoscope for consistent liquid delivery to the lungs.
Key Study Components
Area of Science
- Neuroscience
- Animal Models
- Respiratory Physiology
Background
- Reliable delivery of therapeutics to the mouse lung is crucial for pulmonary research.
- Traditional methods include intranasal administration and surgical cutdown, which can be invasive.
- This new method aims to reduce variability and improve animal welfare.
- It allows for smaller animal cohorts and less invasive procedures.
Purpose of Study
- To develop a less invasive method for intubation in mice.
- To enhance the visualization of the vocal cords during intubation.
- To ensure consistent and reliable liquid delivery to the lungs.
Methods Used
- Setup of a rodent intubation kit with safety wedges and flexible tubing.
- Use of a commercial otoscope connected to a mobile phone for visualization.
- Animal staging and anesthesia procedures to prepare the mouse.
- Confirmation of endotracheal tube placement using visual and tactile feedback.
Main Results
- The method allows for effective visualization of the vocal cords.
- Intubation can be performed with minimal resistance and trauma.
- Liquid delivery to the lungs is consistent and reliable.
- Reduced variability compared to traditional methods was observed.
Conclusions
- This protocol provides a reliable technique for mouse intubation.
- It minimizes tissue trauma and enhances the delivery of pulmonary therapeutics.
- Future studies can build on this method to improve respiratory research.
