Man, you almost had it, you were putting up a really good fight until the end.
Google "contraindications to Nasal Intubation" and there it is; in many printed formats that apnea IS considered a contraindication to nasaling a patient. Backing up your statements with evidentiary documentation is part of proficient critical thinking. If you know you are right, then stick to your guns. It will make you a stronger and more respected medic.
Alas, falling back on the "I was taught this way" and "its in my protocols" is the very premise restricting us from being able to advance our career. We must know the why's!
Please do not take this as a personal attack, I just find it very frustrating when medics make a solid statement, but fail to produce the proof of why. Consider this part of a life long advancement of education.......................
I stand behind my opinion, before I tell you why, lets look at what the professionals say. In the United states, there is a professional opinion that is not only accepted by medical professionals, but also those within the legal system. That would be the professional views from Dr. Ron Walls. In his book, "Manual of Emergency Airway Management", he clearly outlines various algorhithms that truly define airway management. It is on the foundation of this accepted manual and beliefs that I base my view.
So lets look at this scenerio..................
Clenched patient, apnic (o.k. I know that this is a highly unusual circumstance having these two together, but I digress as it can potentially happen), no RSI available. So in essence, you have a "can't intubate" situation. Hopefully, you can still oxygenate with patent nasal passages. If so, then simply assist ventilations with a BVM and get them to more definitive care. If not, as in the assumed scenerio, you now have a "can't intubate, can't oxygenate" (CICO) situation. There is generally only one solution; immediate tube cricothyrotomy. There is only one possible exception to the "CICO = immediate cric" rule; the ability to rapidly place an extraglottic airway device simultaneously with the preparation of the cric (Walls - Manual of Emergency Airway Management, Ch.2-19). In other words, if you can pass a device and successfully turn a CICO into a simply "can't intubate, but CAN ventilate" situation, then you may forego the cric.
Now lets take it a step even further and actually truly secure the airway while simultaneously setting up for the cric. How is it possible, dropping an ET tube on an apnic patient will take longer and is significantly more difficult?!?!?!?!? Or is it?????
In today's age of EMS, we have all sorts of new toys that help with intubation. One of those is the GUM elastic bougie................See where I am going with this??????
How do we perform intubation on grade III or IV airways? We use the bougie to blindly guide us. This is the same concept. Insert the ETT into the nasal passage and hold in the posterior nasopharynx. Slide the bougie through and aim anteriorly, wait for the "clicking" feeling when the bougie slides against the tracheal rings and the advance the tube. It really is that simple and can be done in a matter of seconds. Try it sometime...........
Now of course, RSI would be the ideal remedy as also viewed by Dr. Walls. Also, again the likelihood of having an apnic and clenched pt. is unlikely. But, more people are likely to have bougies than RSI it seems as many medical directors are still shying away from it. Thats a separate argument all in itself!
Hope this was somewhat insightful. Maybe I'll start doing some more scenerios like I used to do a while back. Ever since getting back to the US, I have been re-introduced to the failed education shortcomings of many in EMS. Since we are all here as one happy dysfunctional family, why not have an educational experience when we read throught these threads. Unless we want to continue the current trends of bashing and pointless discussions on TV show similarities and differences. Besides, it will help keep me out of trouble (well, maybe not!).
Stay safe everyone!
