Comparison of the effects of propofol total intravenous anesthesia vs higher dosages of fentanyl anesthesia on myocardial function in CABG operation / 解放军医学杂志

ABSTRACT

Objective To evaluate the effects of different anesthetic methods on myocardial function after the CABG operation and compare the hemodynamic variables under the propofol total intravenous anesthesia with high dosages fentanyl anesthesia. Methods 12 patients (ASA Ⅲ) undergoing selective CABG operation under CPB were randomly divided into two groups (with 6 in each): Group Ⅰ (large dosages of fentanyle anesthesia), and Group Ⅱ (propofol total intravenous anesthesia). The hemodynamic parameters were recorded after induction of anesthesia, after sternotomy, after CPB, and after closure of thoracostomy. Results There were no significant differences of MBP, HR, SVRI, CI, LVEF, and A/E, Tei index between the two groups. Conclusion The method of propofol total intravenous anesthesia (TIVA) was safe, effective and praticable for the CABG operations under CPB.
