  • Title: Hemodynamic effects of isoflurane and halothane in patients with coronary artery disease.
    Author: Mallow JE, White RD, Cucchiara RF, Tarhan S.
    Journal: Anesth Analg; 1976; 55(1):135-8. PubMed ID: 1108706.
    Abstract:
    In 12 patients undergoing saphenous vein coronary artery bypass operations, cardiovascular hemodynamics were studied in the awake state (control) and during anesthesia with isoflurane (inspired concentration, 1.24%, 7 patients) or with halothane (inspired concentration, 0.77%, 5 patients). Isoflurane anesthesia was accompanied by decreases of 19% in the cardiac index (Q), 19% in mean arterial pressure (AP), and 16% in heart rate (HR). Only the change in AP was statistically significant. Halothane anesthesia was accompanied by decreases in Q (28%), AP (22%), and HR (10%). The changes in Q and AP were significant. HR did not change significantly following the induction of anesthesia with either agent. The decrease in AP was similar with both agents, and, in this regard, neither agent was clearly superior for patients with occlusive coronary artery disease.
