高血压患者不同体位动态血压的监测

目的了解高血压患者仰卧位、侧卧位、坐位、站立位动态血压测量有否不同。方法对51例动态血压监测的高血压患者,选用右上肢肱动脉测压法,分别测量不同体位的血压。结果仰卧位、左侧卧位、右侧卧位、坐位、站立位时的收缩压平均分别是152.10±14.55、129.21±14.92、150.42±15.54、149.87±14.84、147.85±12.67 mm Hg;舒张压平均分别是87.81±6.92、70.83±8.32、88.33±11.52、88.81±9.15、87.25±11.15 mm Hg。与仰卧位时动态血压测量的结果比较,左侧卧位时收缩压平均低22.89 mm Hg,舒张压平均低16.98 mm Hg,P<0.01;右侧卧位时收缩压平均低1.68 mm Hg,舒张压平均高0.52 mm Hg,P>0.05;坐位时收缩压平均低2.23 mm Hg,舒张压平均高1.00 mm Hg,P>0.05;站立位时收缩压平均低4.25 mm Hg,舒张压平均低0.56 mm Hg,P>0.05。结论高血压患者右侧卧位、坐位、站立位时与仰卧位时动态血压测量的结果无明显变化,左侧卧位时动态血压测量的结果显著低于仰卧位时动态血压测量的结果。

Comparative study of ambulatory blood pressure monitoring of different positions in patients with hypertension

Objective To investigate whether ambulatory blood pressure monitoring of lateral position,supine position,sitting position and standing position was different or not in patients with hypertension.Methods Blood pressure measurement of supine position,left lateral position,right lateral position,sitting position and standing position was measured in 51 hypertension patients,with ambulatory blood pressure monitoring by the brachial artery of right upper limb.Results The mean systolic pressure of supine position was 152.10±14.55mm Hg,that of left lateral position was 129.21±14.92mm Hg.There was significant difference in the two groups,P〈0.01.The mean systolic pressure of right lateral position,sitting position and standing position was separately 150.42±15.54mm Hg,149.87±14.84mm Hg and 147.85±12.67mm Hg,which were no significant difference with that of supine position,P〉0.05.The mean diastolic pressure of supine position was 87.81±6.92mm Hg,that of left lateral position was 70.83±8.32mm Hg.There was significant difference in the two groups,P〈0.01.The mean diastolic pressure of right lateral position,sitting position and standing position was separately 88.33±11.52mm Hg,88.81±9.15mm Hg and 87.25±11.15mm Hg,which were no significant difference with that of supine position,P〉0.05.Conclusion There was no significant difference between supine position and right lateral position,sitting position or standing position in ambulatory blood pressure monitoring of different positions.The mean systolic pressure and diastolie pressure of left lateral position were lower than those of supine.
