Well, of course there's a tactful and compassionate approach to take with family members who are facing the death of a loved one. Of course nobody would say to them them, yeah, this is going nowhere, we're going to pull the tube and kill your son, mmmkay?
The point I'm getting at is that when we talk to families and discuss withdrawal of care, we should be able to present organ procurement for donation as an ethical alternative to removing tubes and shutting off equipment and waiting and then hastily snatching ever-more-degraded organs for transplant. Objectively, both actions result in hastening global cellular death and shortening the time to signing a death certificate, but one is clearly superior in terms of organ viability for donation.
Don't you think that many (most?) families that have made the hard choice to withdraw care and donate organs would want to maximize the odds of those organs being transplanted successfully? You'd still have some who'd want the tube pulled and the pumps turned off so they could sit with their loved one and wait for the agonal respirations to fade and halt, and that's OK. But I think a lot more would rather say their goodbyes and take additional comfort in knowing that subsequent transplants were going to be done in a way that would maximize the odds of success.
Or maybe I'm just crazy.
