I am a third year anesthesiology resident and I figured, during my years of training, that I should observe my consultants, get the reason behind every practice, and decide on my own what methods to use. One of these methods is the use of a modified nasal trumpet, or MNT, as you have described. I could not find a discussion of it in any text book, but found it occasionally useful for delivering oxygen to sedated patients. One time my fellow doctor saw me doing this and challenged its use. I could not counter that it does deliver more FiO2 than a regular nasal cannula since I couldn't give any known measurements; there is of course the difficulty of air entrained through the other nostril. He added that it looked ludicrous and that I would not find its use in any other hospital. I am glad to have downloaded your article over the Internet, as I can at least say that other doctors have used the MNT and had sufficient faith in it to conduct a study. I still can't explain the FiO2, though. Conflict of Interest:None declared |
