ObjectiveTo evaluate the effect of propofol/isoflurane,sevoflurane/remifentanil on cardiovascular system in the elderly patients undergoing lapsroscopic surgery.MethodsSixty-two ASA I or II patients undergoing elective laparoscopic cholecystectomy were randomly divided into two groups:propofol group(n= 31,group P)and isoflurane group(n= 31,group I). After rapid induction all patients were intubated with a tube.Anesthesia was maintained with continuous infusion of propofol 0.1 mg ·kg-1 ·min-1 and isoflurane 1 μg·kg-1·min-1 in group P,0.8%-1.5% end-tidal concentration of sevoflurane and remifentanil 1 μg·kg-1 ·min-1 in group I. Hemodynamic variables including cardiac output(CO),cardiac index(CI) were continuously measured through-out anesthesia.ResultsThe hemodynamic status of all patients was little influenced by any one of two anesthesia techniques in P group or in S group at clinical dosages.ConclusionsIn ASA I or II elderly patients undergoing lapsroscopic surgery propofol affects CO,CI in a similar degree to sevoflurane.
