Why the study?
Does thoracic epidural analgesia reduce postoperative myocardial ischemia compared to intravenous patient-controlled analgesia in patients undergoing aortic surgery?
Does thoracic epidural analgesia reduce postoperative myocardial ischemia compared to intravenous patient-controlled analgesia in patients undergoing aortic surgery?
Thoracic epidural analgesia and intravenous patient-controlled analgesia provide similar rates of postoperative myocardial ischemia after aortic surgery.
No takes yet. Share an insight, caveat, or question.
Either technique is acceptable without differential ischemia risk; confirms equivalence after aortic surgery.
Bois et al. (1997) studied this question.
