Central delivered adrenaline is used to close down peripheral circulation during cardiac arrest to encourage the poor flow to perfuse the heart, lungs and brain. Maintaining tissue viability until recovery.
Peripheral adrenaline is used in anaphylaxis.
Either makes sense in the context you describe. I must be missing something.
Are you misremembering stuff?
If it wasn’t adrenaline, what else could it be? I went in and out of waves of in outside this world to inside the room to outside this world and inside the room. Until I was firmly inside the room and out if the trip. It was fast.
And it was into my vein, they tied a rubber hose around my arm. I watched the needle go in. And I had to hide my arm for weeks cause it looked like I injected - all bruised and stuff. Few holes. Must have missed with me moving about.
I also have a vivid memory of the heart beat monitor showing 240!
Name sounds enough like adrenaline to mix them up, and would have felt like death. Adenosine is rapidly metabolised so it needs to be delivered into a reasonably large vein and pushed with a bolus so I can't imagine it wrecking your arm where the cannula was placed.
And I looked up cannula and bolus, but I only remember a syringe with a needle attached to it. My memory might be wrong though.
Oh fun fact: When an ambulance was called and they basically dragged me into the hospital bed. As they injected me with adrenaline, that scene from Matrix happened to me as real as day (obv not tho) of when Neo touches the mirror and it goes up his arm and over him - I hallucinated that it was happening to me, watching the cold metalic liquid travelling up my arm. It was quite out there stuff!
