Abstract:
In 2D surgical paients wihose general anesthsia was maintained with one to one ratio of oxygen and nirtous oxide and 1 vo19 of halothane, 1 mg/kg of lidocaine was administered to the 10 patients in each group intravenously to evaluate the effects of lidocaine on cardiovascular changes. In these clinical study, heart rate (HR), mean arterial pressure (MAP), stroke volume (SV) and cardiac output (CO) were measured iri one minute interval after intravenous administration of lidocaine and these values were compared with the control. The following results were obtained: 1) There are no significant changes of the heart rate. 2) The mean arerial pressure was significantly decreased one minute after that, there was no significant change. 3) There were no signifieant changes in the stroke volume. 4) The cardiac outit was significantly decreased in all patients after the administration of lidocaine and there were also the significant decrease of the cardiac output three and four minutes in patients with 1.0 mg/kg of lidocaine and four and five minutes in patients with 1.5 mg/kg of lidocaine after the administration of lidocaine.
