Dr. H. Tristam Engelhardt is a physician and an Orthodox Christian bioethicist; I am on the last chapter of his book The Foundation of Christian Ethics, a monumental work. He has also written the following works which bear directly on our focus:
H. Tristram Engelhardt, Jr. “Physician-Assisted Suicide and Euthanasia: Another Battle in the Culture Wars.” Physician-Assisted Suicide, eds. Loretta Kopelman and Kenneth De Ville: 29-41.
H.T. Engelhardt, Jr. “Physician-Assisted Suicide Reconsidered.” Christian Bioethics, 4 (1998) : 143-167.
H. Tristram Engelhardt, Jr. “Redefining Death: The Mirage of Consensus.” The Definition of Death (1999) : 319-331.
H. Tristram Engelhardt, Jr. “From Abortion to Euthanasia: Rethinking the Value of Life at the End of the Christian Age .” Life-The Human Being Between Life and Death (2000) : 195-207.

Also, Death and Life After Christendom, from the Touchstone Magazine archives: http://www.touchstonemag.com/archives/article.php?id=14-05-018-f And here is his profile from Orthowiki: http://orthodoxwiki.org/H._Tristram_Engelhardt
Here is the “futile care” category page on a site by an Orthodox Christian who is an Emergency Medicine Resident Physician: http://www.studentdoctor.net/pandabearmd/category/futile-care/
Here is a case study, Care of an Unresponsive Patient with a Poor Prognosis, by Arthur S. Slutsky, M.D. and Leonard D. Hudson, M.D. There are 3 options listed; under option 2, (Write a Do-Not-Resuscitate Order and Transfer the Patient to a Skilled Nursing Facility) in the comments, there are responses by some Greek physicians, one of whom (George Nikos) explains his position with reference to the Orthodox Church: http://220.127.116.11/search?q=cache:1ay5TDc5C3MJ:www.nejm.org/clinical-decisions/default.aspx%3Fid%3DNEJMclde0808330+%22futile+care%22+%22Orthodox+Church%22&cd=4&hl=en&ct=clnk&gl=us
This unnamed blogger, most surely an Orthodox Christian, provides a concise post with Some links with info on the Terri Schiavo case: http://perennialrambler.blogspot.com/2005/03/some-links-with-info-on-terri-schiavo.html An expose of the horror and injustice of her tragic manner of death.
Khorea Frederica Matthewes-Green has also, through the years, thoughtfully commented on Euthanasia: http://www.frederica.com/display/Search?searchQuery=euthanasia&moduleId=1772899
This is the last of the 4 posts which have been meant to be Orthodox Christian resources toward the discernment of a stance on futile care. My prayer is that our God-loving Hierarchs and Spiritual Fathers, together with all Orthodox Christians of true worship, will be granted the wisdom to discern these matters with Light from above, as the issues come before us in a personal way, as they surely will.
