Abstract/OtherAbstract:
Cerebral symptoms were registered in a multicenter study including 64 patients with severe hypertension, diastolic blood pressure (DBP) greater than or equal to 135 mmHg, and more or less pronounced hypertensive encephalopathy. The symptoms were: headache (70%), dizziness (35%), consciousness disturbances (28%), nausea (27%), paresis (23%), blurred vision (22%), paraesthesia (21%) and vomiting (14%). None had convulsions or coma. Initial treatment was furosemide i.v., and if DBP was greater than or equal to 125 mmHg after one hour, patients were randomized to treatment with either i.v. diazoxide (bolus injections of 75-150 mg) or i.m. dihydralazine (bolus injections of 6-12.5 mg). A gradual fall in blood pressure (BP) was obtained in all three groups. Along with BP reduction a substantial regression of neurological symptoms was registered. After 5 hours only minor cerebral symptoms were present without significant difference between diazoxide and dihydralazine. None developed cerebral complications. The study failed to show a significant correlation between BP reduction and regression of neurological symptoms graded semiquantitatively. Reduction of BP by titration using small repeated bolus injections is recommended, but oral treatment should be considered in the patients who are able to ingest peroral medication in spite of neurological symptoms.
