Objective To investigate the effect of blood pressure control for early enlargement of hypertensive intracerebral hemorrhage.Methods A total of 96 patients were divided randomly into intensive blood pressure lowering group (n = 48 )and standard antihypertensive group(n=48).Patients were checked head CT and was evaluated defect of nerve function score immedi-ately when they arrive at hospital and after 24 hours.Then the clinical curative effect was evaluated.Results The defect of nerve function score in intensive blood pressure lowering group was lower than that of the standard antihypertensive group(P <0.05 ). The hematomas volume within 24 hours of admission and the rate of hematoma enlargement of intensive blood pressure lowering group were sharply smaller than those of standard antihypertensive group(P <0.05).Conclusion Controlling blood pressure ac-tively could decrease ratio early enlargement of hematoma and defect of nerve function score in patients with hypertensive cerebral hemorrhage.
