Anesthesiologists were surveyed to determine their experience and opin
ions regarding ''Do Not Resuscitate'' (DNR) orders in the perioperativ
e period. Four hundred fifteen questionnaires were mailed and 193 (47%
) were returned. One hundred sixty-one (87%) of 186 respondents had be
en requested to provide (and more than two-thirds had provided) monito
red anesthesia care, regional anesthesia, or general anesthesia to a p
atient with a DNR order. Almost two-thirds of the respondents assume D
NR suspension in the perioperative period and only half discuss this a
ssumption with the patient/guardian. Less than 50% of respondents woul
d require DNR suspension for a palliative procedure contrasted with >6
0% for an elective procedure. After agreeing to a patient's decision t
o retain their DNR status, >67%, >58%, <49%, and <33% would utilize po
sitive pressure ventilation with a mask, vasoactive drugs, endotrachea
l intubation, or defibrillation, respectively, in the event of a cardi
opulmonary arrest in the perioperative period. These findings suggest
much ambiguity regarding DNR orders in the perioperative period. Furth
er discussion among physicians and patients is warranted.
