    Abstract:
    Effects of nicardipine on endocrine functions were evaluated in 10 surgical patients who received surgeries under total intravenous anesthesia with droperidol, fentanyl and ketamine (DFK). Plasma levels of norepinephrine (NE), epinephrine (E), plasma renin activity (PRA), aldosterone and atrial natriuretic peptide (hANP) were measured following nicardipine injection during 30 minutes of intraoperative hypertension. When the systemic blood pressure exceeded 160 mmHg systolic and 95 mmHg diastolic for five minutes, 0.5 mg approximately 10 mg of nicardipine was administered for 30 minutes to maintain the systolic blood pressure below 160 mmHg. Following the injection of nicardipine a significant reduction by 20% in the mean systolic and diastolic pressure was observed. Mean heart rate increased by 5%, but the increase was not significant. Plasma NE increased significantly 1.7 time from the control level at 15 minute following the injection. Plasma levels of E, PRA, aldosterone and hANP showed no significant changes.
