Abstract
In this study, we aimed to evaluate the changes in blood pressure and heart rate in geriatric patients, whose response to the catecholamine release were insufficient as according stress factors, by applying anaesthesia with propofol-N20-fentanyi combination.
Group I involved 11 cases(18-65 years) and Group II involved 13 cases(65-87years). 3 m/kg fentanyi, 0.25 mg/kg dehydrobenzperidoi (DHB), 1.5 mg/kg propofol and 0.1 mg/kg vecuronium were used for induction. Maintenance of the anaesthesia was provided with propofol infusion 3.5 mg/kg/h and 50% N20-02 inhalation. Systolic blood pressure(SBP), diastolic blood pressure(DBP), mean arterial pressure (MAP) and heart rates (HR) were measured before induction, after induction and 1, 3, 5, 10 and 30 minutes after intubation. The recovery periods of the cases were recorded.
SBP, DBP and MAP values of Group I were found decreased a fter induction. These values were remained all through the anaesthesia in Group II. HR was found decreased significantly at l(fh and 3(fh minutes of anaesthesia in both groups (p
