I saw this by member @Mkoll writing on suttacentral and thought it well worth adding here:
Mkoll: I live in the USA, was an ICU nurse for 3 years, and administered IV morphine to many dying patients. A few points from my experience.
IV morphine is one of the standard drugs prescribed when a patient is put on “comfort measures” at the end of life. IV lorazepam (Ativan) is another standard drug—it’s in the benzodiazepine drug class and relieves anxiety, reduces agitation, and causes anterograde amnesia (you’re likely to forget what happens after receiving it and while it’s affecting you). They can be prescribed as PRN (“as needed”) boluses or as a continuous infusion.
“Comfort measures” means that the patient’s condition is terminal, death is close, and the decision has been made to stop trying to cure the condition and instead direct care toward keeping the patient comfortable.
At the point when comfort measured are ordered, some patients are unconscious or delirious and can no longer make decisions for themselves—someone else, whether family members or the physician, makes this decision. Others are fully conscious and aware—they may choose to be put on comfort measures of their own volition. We won’t have a choice about what group we fall in when we approach death since it depends on our condition and disease process. It’s a good Dhamma lesson, teaching us that these things are not under our control or subject to our wishes.
Not every patient is put on comfort measures. Some patients or families want the medical team to do everything to keep them alive. We do this, but eventually they will “code” which means their heart stops and we try to resuscitate them (CPR, drugs, etc.).
By default, patients in the hospital are a “full code” meaning we will try to resuscitate them if their heart stops. If a patient has a Do Not Resuscitate (DNR) order, we won’t do this. Anyone with decision-making capacity can request a DNR for themselves.
As a patient in the hospital with decision-making capacity (i.e. not intoxicated, psychotic, delirious, etc.), you have the right to refuse a treatment. This stems from the ethical principle of autonomy. If you don’t want morphine, just say so.
Personally, if I still have decision-making capacity at the end of life, I would be OK with IV morphine if I felt I needed to take the edge off pain to better maintain mindfulness. I would only ask for a dosage of just that much. But I would likely decline Ativan because I think it would reduce my awareness in a way that morphine in appropriate doses wouldn’t. And I would have a DNR in place.
