I had a guy with that actually. Internal Decapitation and locked in but AO3/GCS15 after being hit by a rented street racing sports car while crossing the road on south beach.
He blinked out that he wanted palliative extubation and to donate his organs. Ethics, palliative, everyone got together and decided he had capacity and if he wanted to be extubated that was within his rights.
So organ procurement typed him, found organ recipients, and I rolled with him to the OR at 3am for the procurement. Confirmed one final time that I’m going to take the tube out and he blinked “Yes”. I had had a 250 mL bag of 1 mg/mL morphine from pharmacy.
We pulled the tube, and he looked me right in the damn eyes the entire time as his sat drifted down. I just kept pushing morphine 10 mg at a time (for air hunger) until he closed his eyes and drifted off. I remember really distinctly just saying “AGAIN” over and over as the anesthesia tech passed me the morphine syringes. PEA—>asystole on the monitor a moment later, I called time of death, and the transplant surgeons flooded his body with iced saline and went to work for the procurement.
Then I walked out of the OR and sobbed like a freakin baby.
That crap was the bravest thing I’ve ever seen a patient do.
