Maybe I did misunderstand, but regardless this is a good discussion to have.
Kaisu...I very rarely bring chat discussion into the forums and do my best to stay out of drama, but I felt that this was a good topic to discuss, so I brought it over here.
It just surprised me when I came into the chat room and read that this person used a Mac 4 for every intubation. Questioned further I became concerned that a Mac 4 was being used on an infant. If I did not get the entire story, I apologize but the situation because heated rather quickly and I decided to step out to not cause drama. Regardless, I think this is a pretty good discussion of how to adapt when equipment fails.
So we all agree, that a Mac 4 should only be used in a last ditch effort to intubate. Personally, I would probably attempt digital intubation or use a small OPA to lift the jaw than use a large blade. I don't have one here in my hands, but from memory the Mac 4 has a pretty wide blade to support the size of an adult tongue and jaw, most newborns mouths are not very big, I would have a hard time visualizing the cords. But that's just me.
As far as equipment failure, the only time I have seen a laryngoscope blade break was someone dropped it, or stepped on it. Those things are pretty tough in my experience. Checking your equipment before each shift should include checking the bulbs of every blade and making sure you have at least one of each size blade, if not more. I understand things can malfunction at anytime but we can minimize this by maintaining our equipment with regular maintenance and various other steps.
Again sorry to have people all in an uproar at me, not my intention with this post.
