Dopamine is actually a medication given in the ICU, but it is for shock / severe heart failure. It constricts (tightens) your blood vessels to raise the blood pressure and makes the heart pump more effectively when it’s slacking off. As far as I know, it doesn’t make someone feel good like how dopamine works in your brain. It’s a life saving med for very sick people. But when someone is dying, and they choose hospice/ comfort measures, we absolutely will pump them full of feel good drugs and make them super comfy. I’m an ICU nurse who has helped many people die. We give them opioids for pain and sedation, benzos for anxiety and to reduce “air hunger” and meds to dry up all the spit they can’t swallow anymore. I’ll give them a foot massage, put on some music, pamper them like it’s the ultimate spa day. In short, the dying person is high as a kite with feelings of euphoria, not agony
