https://www.vetnurse.co.uk/f/clinical-discussions/30985/what-are-the-age-restrictions-for-using-nitrous I've always had the idea of not being able to use nitrous in patients under about 6 months of age, however I would prefer some more concrete evidence so I can be certain of what I'm teaching new nurses, so any help would be greatly appreciated!!! en-USTelligent Community 10
