目的 观察76例患者晨间血压的变化，探讨预防高龄高血压患者晨峰时段血压骤变导致意外的护理措施，以加强预见性护理。方法 选择住院治疗行动态血压检查的患者76例，均为男性，60~97岁，平均（80.28±7.23）岁，并以80岁为界，＜80岁为低龄组35例，≥80岁为高龄组41例，观察晨间血压变化及进餐、服用降压药后对血压的影响，分析年龄、临床症状与血压变化的关系。结果 76例晨峰时段服药、进餐后血压均呈下降趋势；高龄高血压患者服药、进餐后各时间段收缩压与服药进餐前比较均有明显统计学差异（P＜0.01，P＜0.05），且临床症状发生率较高。结论 高龄高血压患者晨峰时段是病情观察的重点时段，因此，进行晨峰时段防止进餐、服药后血压下降所致意外的健康教育非常必要。

Objective To observe changes in blood pressure (BP) during morning rise in elderly patients with essential hypertension, so as to take effective measures to prevent some unexpected accidents. Methods We measured the changes in BP during morning blood pressure rise in 76 elderly patients. Results There was a marked drop of BP in 76 elderly patients at 30,60,120,and 180 minutes after taking breakfast and medicine (P＜0.01，P＜0.05), especially in those aged over 80. It showed that more clinical symptoms with meal and medicine -related drop of BP occurred in elderly patients. Conclusions We should take effective measures to prevent some unexpected accidents associated with meal and medicine -related drop of BP in elderly patients. We should pay more attention to giving elderly patients health education.
