First of all, for what do you want to give an intratracheal installation to mice? ¿Is it for administration of a drug? You need to clarify this and then we can give you proper answers.

Here are some publications, you should ready it for your experiments.

Thank You Felipe and Andrei

First and foremost you should consult with your animal care/veterinary staff for advice and training. Another poster has provided a JOVE link - there are multiple protocol videos posted.

I agree with Jay. While online write-ups on animal procedures are very good places to start learning (and the SOT review brings up some good caveats about when this technique is useful or not), your IACUC will get the final say on what you can do and will give you actual hands-on training.
