目的：探讨餐后不同体位对老年高血压伴餐后低血压患者血压的影响。方法将32例老年高血压伴餐后低血压患者于进食早餐后随机分配为坐位、平卧位及左侧卧位3种体位，采用动态血压计监测餐后2h内血压的变化。结果进餐后无论保持卧位、坐位还是左侧卧位的患者，在进食早餐后45 min出现明显的血压下降，60 min-75 min收缩压与舒张压降至最低点，90 min时逐渐开始回升，120 min时与餐前基本相同（P＞0．05）。不同时点不同体位的收缩压与舒张压监测结果比较差异均无显著性（P＞0．05）。结论餐后不同体位对老年高血压伴餐后低血压患者的血压无明显影响。%Objective To explore the influences of different body positions on blood pressure of elderly hypertension patients with postprandial hypotension (PH) .Methods Thirty-two elderly hypertension patients with PH were randomly assigned to sitting ,horizontal and left-lateral posi-tion after breakfast ,their BP changes within 2 hours after breakfast monitored using ambulatory sphygmo-manometer .Results Regardless of body position BP lowered notably at 45 minutes after breakfast ,sys-tolic and diastolic pressure did to lowest point during 60~75 minutes ,went up again at 90 minutes ,and recovered to pre-breakfast levels at 120 minutes basically (P>0 .05) .There were no significant differences in systolic and diastolic pressure monitoring results at different time periods in different positions ( P>0 .05 ) .Conclusion Postprandial different body positions have no obvious influence on BP of elderly hyper-tension patients with PH .
