BackgroundPatients undergoing surgical coronary revascularization typically recover in an intensive care unit where many aspects of patient care are protocolized despite absence of widespread evidence-based guidelines on perioperative management. It was hypothesized that the postoperative management strategies varied significantly among units.MethodsWe surveyed 31 Canadian cardiac surgical intensive care units to obtain their postoperative standing orders. Management strategies after coronary bypass surgery were compared to identify areas of variability in the care of frequent clinical scenarios.ResultsIn all, 28 units (90%) responded, and 26 sites (84%) reported using at least 1 formal postoperative protocol. All but 1 of the responding units (96%) have specific orders for coronary artery bypass graft patients. Orders for allogeneic red blood cell transfusion threshold, postoperative extubation pathway, analgesia, and atrial fibrillation management were present in 40%, 74%, 60%, and 57% of the responding units, respectively. A protocolized trigger to notify the surgeon was specified for bleeding and hypotension in 75% and 35% of the centres, respectively. A standing order for aspirin administration was used in 91% of the centres, and statin administration was mentioned in 41%. Despite the frequent use of protocols in postoperative care, the content of the protocol varied significantly from centre to centre.ConclusionThe majority of Canadian centres use at least 1 formal protocol for the care of the postoperative coronary revascularization patient. There is, however, significant variability in these management protocols. Future studies should examine whether implementation of standardized protocols improves outcomes and what treatment strategies are optimal in postoperative cardiac surgical patients.Copyright © 2011 Canadian Cardiovascular Society.
