Mouse/Rat endotracheal intubation is to put a unique endotracheal tube into the trachea through the glottis of a mouse or a rat, then ventilate and supply oxygen, and provide the best conditions for lung diseases modeling and drug administration.
Tracheal intubation is one of the basic operations of animal experiments, such as thoracotomy, respiratory function test, and tracheal administration. Because of the special anatomical structure of the mouse mouth, the lower forehead can not be opened entirely.
The best way is to use the external light source to make the throat airway visible and then use the endotracheal tube to do tracheal intubation. This method is simple, time-consuming, and has a high success rate.
Methods to apply endotracheal tube intubation
Simply speaking, tracheal tube intubation is to put the mouse/rat lies on his back, uses the light source to illuminate the larynx, opens the jaw so you can see the glottis, then intubate the endotracheal tube clearly.
Tracheal intubation in rats is usually performed by visual intubation, blind intubation, and tracheotomy (tracheal intubation in mice is similar to that in rats).
The method operation is cumbersome, not friendly to the inexperienced operator.
The operator uses a high-power light source to stick to the mouse’s neck, and with the help of the light through the neck, we can see the glottis by pulling the tongue root of the mouse to improve the success rate of the intubation method. If there is no endotracheal intubation platform, this operation method needs the assistance of another person.
Tips: The light source is better adjustable for its position and luminance.
Blind intubation may damage the mouse’s pharynx and generate secretions of a large amount of mucus in the airway, which may lead to asphyxia in mice and rats. It may cause infection after drug administration and not easy to recover.
It is easy to put the endotracheal tube into the esophagus wrongly, and it needs repeated tries to get success.
Tracheotomy is an accurate way to apply endotracheal intubation, it needs to cut the neck skin to see the airway and then cut it to put in the endotracheal tube. This method may damage the cervical nerves and blood vessels, cause postoperative local infection and complications, resulting in secondary trauma and affecting experiment data stability.
You may select the proper intubation method according to the purpose of the experiment.
Material and size of the mouse endotracheal tube
The mouse intubation tube is made of PU material with moderate softness and hardness, which is protective to the trachea of the mouse and rat.
2 options of length:3.8cm and 11cm
|Type||Inner Diameter(mm)||Outer Diameter(mm)|
The mouse endotracheal tube can connect with an injection syringe without the Y-shaped connector.
