Aortic surgery markedly elevates day-of-surgery mortality risk in ASA 1-3 elective patients; leaves open whether targeted protocols can reduce these rare events.
What factors are associated with unanticipated day of surgery deaths in ASA physical status 1, 2, and 3 elective surgery patients?
While rare (0.08%), day of surgery deaths in low-to-moderate risk elective surgery patients are strongly associated with aortic surgery and specific preoperative factors, with some potentially preventable by improved anesthesia care.
Bishop et al. (2008) studied this question.
