A Simple Method of Mouse Lung Intubation

Overview

This paper describes a straightforward and efficient method of intubating mice for pulmonary function measurements or pulmonary instillation. The procedure allows the mice to recover and be studied at later times, utilizing an inexpensive fiberoptic light source that directly illuminates the trachea.

Key Study Components

Area of Science

• Neuroscience
• Biology

Background

• Intubation is essential for mechanical ventilation or liquid installation in research.
• The procedure requires specific equipment for successful execution.
• Proper positioning of the mouse is crucial for effective intubation.
• Recovery of the mouse post-procedure allows for later study.

Purpose of Study

• To develop a reliable method for intubating mice.
• To facilitate pulmonary function measurements.
• To enable the installation of liquids for experimental purposes.

Methods Used

• Assembling the cannula and light source.
• Hanging the mouse vertically by the upper incisors.
• Manipulating the mouse's head and body for a straight intubation path.
• Inserting the fiber optic introducer and cannula through the vocal cords.

Main Results

• The procedure allows for successful intubation of the mouse.
• Mice can recover and be studied later, demonstrating the method's efficiency.
• The use of a fiber optic light source enhances visibility during intubation.
• Mechanical ventilation or liquid installation is achievable post-intubation.

Conclusions

• This method provides a simple and effective approach to mouse intubation.
• It supports various experimental procedures in pulmonary research.
