So you prescribe death by dehydration/starvation for everyone who cannot swallow on their own.
No. In my opinion as wrong its as wrong to say everyone who could possibly be kept alive with parenteral nutrition should get it as it is to say everyone who needs it should be denied.
However, surgically implanting tubes is not natural, is undeniably a “medical treatment,” and is certainly not a “human right” by any stretch of the definition.
Discretion of called for here I think. Not just called for, but a necessity, because if there is one thing I can say for certain on this issue its that an all or nothing rule either way isn’t going to be acceptable to the vast majority of people.
