目的探讨住院老年人餐后低血压(PPH)的发生率及血压降低幅度。方法对住院老年人的血压每天早、午、晚餐前30min及餐后30min、60min、90min进行测量,连续3d,将血压下降幅度收缩压(SBP)≥20mmHg,舒张压(DBP)≥10mmHg作为统计标准。结果PPH发生率SBP为86.66%,DBP为76.66%,男性高于女性(P<0.05)。血压降幅:早餐SBP平均降幅(26.95±15.16)mmHg,DBP为(14.78±6.18)mmHg。性别比,男性组降幅大于女性组(P<0.05)。各年龄段发生率,早餐70～79岁组高于其他年龄组,而晚餐则相反。结论老年人PPH发生率很高,应关注老年人PPH患者,予以预防和干预,防止因低血压引起不良事件发生。
Objective To investigate the incidence of postprandial hypotension (PPH) and the extent of blood pressure reduction in hospitalized elderly patients. Methods The blood pressure of senile elders was measured daily at 30min, 30min, 30min, 60min and 90min after dinner, and the blood pressure was decreased by SBP ≥20mmHg and DBP ≥10mmHg as statistics standard. Results The incidence of PPH was 86.66%, DBP was 76.66%, male was higher than female (P <0.05). Blood pressure drop: breakfast SBP average decline (26.95 ± 15.16) mmHg, DBP (14.78 ± 6.18) mmHg. Sex ratio, male group decreased more than female group (P <0.05). The incidence of all age groups, breakfast 70 to 79 years old group than in other age groups, while dinner is the opposite. Conclusion The incidence of PPH in the elderly is very high. Patients with PPH in the elderly should be concerned about the prevention and intervention to prevent adverse events caused by hypotension.
