RESUMEN
Objective To study the efficacies and adverse reactions of urapidil and nicardipine in the treatment of the chronic renal failure patients with hypertensive emergencies .Methods 59 chronic renal failure patients with hypertensive emer-gencies were randomly divided into nicardipine treatment group and urapidil treatment group .The patients in the nicardipine group were given a 1 mg nicardipine intravenous injection ,and 30-100 μg/min intravenous transfusion was given continuously . The patients in the urapidil group were given a 12 .5 mg urapidil intravenous injection ,and 150-500μg/min intravenous trans-fusion was given continuously .The dosage were changed according to the patients′blood pressure in both of the groups .The patients′blood pressure ,heart rate and adverse reactions were recorded .Results The patients′blood pressure in both of the groups were significantly lower after treatment (P<0 .05) .The SBP in nicardipine treatment group was significant lower than SBP in urapidil treatment group in the first hour after treatment (P<0 .05) .There was no significant difference in SBP be-tween the two groups 2 hours after treatment (P>0 .05) .There was no significant difference in DBP between the two groups after treatment (P>0 .05) .In the nicardipine group ,the heart rate rose after the treatment ,the difference was statistically significant (P<0 .05) .While in the urapidil group ,the heart rate went down after the treatment ,and the difference was statis-tically significant (P<0 .05) .There was no significant difference in adverse reactions between the two groups (P>0 .05) . Conclusion Both of nicardipine and urapidil were effective in the treatment of chronic renal failure patients with emergency hy-pertensive .Nicardipine was more effective in reducing the SBP in the first stage of treatment .
