16、techniques,may avoid intraoperative crystalloid infusions.There is no evidence basis by which to select either an induction or a maintenance anesthetic drug in these patients We have successfully used most IV induction drugs in these patients(including thiopental,propofol,ketamine,etomidate,midazola

21、 hypotension).Finally,transfusion for perioperative anemia in a hemodynamically stable patient with a history of HF(e.g.,stage C)must be approached with greater caution than usual.It is easy to produce intravascular volume overload in these patients When we consider our aging patient population in w

22、hich prolonged survival with hypertension and/or coronary artery disease is expected and the better HF treatment strategies now available to them,we conclude that anesthesiologists will encounter an increasing number of patients with either a predisposition to HF(stages A and B)or a history of HF(stages C and D).Thus,knowledge of the evolving pharmacologic strategies for the management of chronic HF is essential both for patient care and for our continued credibility as perioperative
