血压波动对脑梗死急性期的影响作用

The effects of fluctuation of blood pressure in patients with acute cerebral infarction

目的 研究急性脑梗死患者血压变化规律及其与神经功能损伤的关系。方法 通过动态血压监护 ,探讨急性脑梗死患者血压变化规律及其对神经功能损伤的影响。结果 急性脑梗死发病后血压先迅速升高 ,维持 3d左右后自发回落 ,至第 7日基本稳定。约 3 8%的急性脑梗死患者血压回落明显 ,其中 5 6%伴发神经功能损伤进展。发病年龄高、初始神经功能损伤严重和大剂量应用甘露醇、硫酸镁、硝酸甘油与血压降低有关。结论 急性脑梗死患者血压呈先增高再回落的自发趋势 。

Objective To study the regular rule of fluctuation of blood pressure and its relation with the dysneuria in patients with acute cerebral infarction.Methods To investigate the rule of fluctuation of blood pressure and the effects on nervous function by dynamic blood pressure monitoring.Results Blood pressure elevated rapidly after acute cerebral infarction,spontaneously fell after maintaining 3 days,and stabilized on the 7th day .Blood pressure fell evidently in 38 percent of patients with acute cerebral infarction,in 56 percent of whom nervous function was damaged.The fall of blood pressure was related to advanced age at the onset,serious primary dysneuria,massive mannite,magnesium sulfate and nitroglycerin. Conclusion Blood pressure elevated and then fell spontaneously in patients with acute cerebral infarction.Excessive fall of blood pressure can lead to advanced dysneuria.
