Reconsidering do-not-resuscitate orders in the perioperative setting.

Many of our elderly have now signed advance directives or physicians' order sets of life-sustaining treatment forms. Frequently, choices have been made for no life-sustaining interventions at the end of life or do-not-resuscitate (DNR) orders. As the proportion of elderly grows and more patients seek surgical intervention for comfort or to improve their quality of life, the medical and ethical issues of DNR orders in the perioperative setting become increasingly more complex. Many health care providers neither recognize the complexity and significance of the DNR order during the perioperative period nor have hospitals established actions toward resolution of this situation. This article will discuss how this complex issue should be explored, definitions established, and positions recommended.
