[Perioperative β-adrenergic blocking agents and postoperative prognosis].
Perioperative myocardial ischemia occurs frequently within 48 hrs postoperatively, with few characteristic symptoms and its prognosis is known to be poor. Anesthesiologists should carefully monitor these patients with high risk factors for cardiac events until the 2nd postoperative day. Medical treatment should be initiated promptly according to the cause of perioperative increase in sympathetic nervous activity. At present, it is not clear whether beta-adrenergic blocking agents can improve long-term prognosis for patients undergoing noncardiac surgery. However, it is prudent to continue the medication in patients who are given beta-adrenergic blocking agents preoperatively, and to resume the drug postoperatively as soon as possible. Moreover, since elderly patients are prone to suffer from cerebral infarction, sufficient attention should also be paid to changes in blood pressure.
