Guidelines for perioperative do-not-resuscitate policies.

This paper reviews some of the difficulties in implementing perioperative reevaluation of do-not-resuscitate (DNR) orders and suggests several strategies for perioperative DNR policies. Policies should be written, designed and implemented at the level of the institution, and be sufficiently flexible to permit the tailoring of the perioperative DNR order to the individual patient. Policies should unambiguously state that reevaluation is required, delineate responsibilities for reevaluating the DNR order, state all the available options, define the necessary documentation, and list resources for help.
