Awake nasal fiberoptic intubation or at least bougie placement.
1.) Still wondering why he's bleeding like a stuck pig long after biting his tongue. And, I'm wondering how to keep my FOB lens from smearing with blood and clot that's going to make it useless. He denies meds, what about weird foods, supplements, or ASA that he might have loaded up on for a painful back? If direct pressure and packing can't stop the bleeding enough to tropicalize the airway, a successful awake FOB seems like wishful thinking. Even with phenylephrine or oxymetazalone in the nose, if he has some problem with coagulation (vWF deficiency, hemophilia, etc.) the nasal FOB might worsen the blood in the airway. If there's time for coags, then do it before nasal FOB, fix what you can, then
2.) Still wondering why he reached for the Benadryl as his tongue started to swell immediately before losing consciousness. He says no allergies, but any food allergies. Did he eat a peanut coated chocolate banana knowing he's got a mild peanut allergy? Ii sounds like he knew that Benadryl would help anytime his tongue swelled up. Do I need to get prepared for an incredibly worsening upper airway disaster because he is continuing to swell? If he nods his head yes to anaphylaxis as a possibility, treat that in addition to the other problem of a bloody airway - and think more about a quick surgical airway if he completely obstructs.
3.) Why did he lose consciousness and bite his tongue. Did the ED think seizure as a possibility? Did they give him Keppra or another anti seizure med to lower the risk of another seizure occurring (if that was the LOC etiology)? Another seizure is really going to complicate things with a mouth full of blood.
4.) I completely, totally, absolutely believe an ENT isn't available. Just the way it is out in the bad old world. If he was stable when the EMS transferred him to you, maybe you can transfer him back to the originating OSH? Or maybe to a nearby hospital that has otolaryngology actually in house? Probably not an option.
So, you're left with a bloody airway, still actively bleeding, a swollen tongue that might or might not be worsening, a man with a cardiac history, maybe ongoing anaphylaxis / anaphylactoid rxn, and maybe a seizure leading to lost consciousness and biting of his tongue. Oh, and no ENT surgeon immediately available.
Keep the patient calm; don't let him panic more by openly displaying your own fears. A nice calm voice while you talk to everyone. It's not you with the impending loss of the airway. Call the techs (if you're so lucky) to set up the OR with all the difficult airway tools, and make sure the OR knows your coming and staffs the room with surgical nurses, scrub techs, and sets up for a trach. Make sure some type of surgeon knows you'd really love some help in the OR. Stick some gauze soaked in phenylephrine or epi under the tongue to try to slow the bleeding. Treat any possible allergic rxn. Also, give him some glycopyrolate before moving to do what you can to dry things up before moving. 100% O2 nonrebreather to oxygenate as much as you can just in case he completely obstructs. Don't let him lose spontaneous ventilation by over medicating. Move to OR w/ portable suction & him stilling up in the bed and you by the bedside. Melker with you doing transport (
). What's next depends on how things are going when you get to the OR. If there's time to wait then stop the bleeding first, fix any other problems (coags, anaphylaxis, seizure d/o, etc.). If things are getting better, the tongue swelling is resolving, the bleeding is only a trickle, no likelihood of recurrent seizure, consider doing nothing. Otherwise, tropicalize, and proceed with an awake FOB intubation if he'll cooperate. Otherwise, if things are going bad, move on with awake trach if the patient can cooperate.
As long as you can get access to the cricothyroid membrane, you have a fallback emergency plan for a quick surgical airway. If you can't palpate the CTM, use ultrasound to locate and mark it - plenty of manuscripts on that topic - do an emergency surgical airway once he loses consciousness.
