目的通过对老年高血压患者的肱动脉收缩压(brachial aortic systolic blood pressure,bSBP)与中心动脉收缩压(central aortic systolic blood pressure,cSBP)的比较和差异分析,探讨有效控制患者血压的护理方法。方法用无创中心动脉压测量仪对1 194例老年高血压患者进行肱动脉血压和中心动脉压测量,将患者的bSBP与cSBP进行比较,并进行差异性分析。结果老年高血压患者的bSBP比cSBP低,差异有统计学意义(P<0.05)。80岁以下老年高血压患者的bSBP与cSBP比较,差异无统计学意义(P>0.05),而80岁以上老年高血压患者的bSBP明显低于cSBP,差异有统计学意义(P<0.05)。1 194例老年高血压患者中,有37.19%患者的bSBP比cSBP高;有58.37%患者的bSBP比cSBP低;其中有26.55%患者的bSBP与cSBP之差在±1.33kPa(10mmHg)以上。只有4.44%患者的bSBP与cSBP相等。结论老年高血压患者肱动脉压和无创中心动脉压之间差异有统计学意义(P<0.05),80岁以上患者的bSBP明显比其cSBP低,临床上应根据每位患者bSBP与cSBP的差异,采取个体化的护理干预措施。
Objective To compare and analyze the brachial aortic systolic blood pressure (bSBP) and central aortic systolic blood pressure (cSBP) in elderly hypertensive patients to explore the effective nursing methods for controlling blood pressure. Methods The noninvasive central arterial pressure meter was used to measure the brachial and central arterial pressure in 1 194 elderly hypertensive patients. The patients’ bSBP and cSBP were compared and the differences were analyzed. Results The elderly patients with hypertension had lower bSBP than cSBP, the difference was statistically significant (P <0.05). There was no significant difference in bSBP and cSBP between elderly hypertensive patients under 80 years of age (p> 0.05). The bSBP of elderly hypertensive patients over 80 years old was significantly lower than that of cSBP (P <0.05). Of the 194 elderly hypertensive patients, 37.19% of patients had higher bSBP than cSBP; 58.37% of patients had lower bSBP than cSBP; 26.55% of them had a difference of ± 1.33 kPa (10 mmHg) between bSBP and cSBP. Only 4.44% of patients had the same bSBP as cSBP. Conclusions There is significant difference between brachial artery pressure and noninvasive arterial pressure in elderly patients with hypertension (P <0.05). The bSBP in patients over 80 years old is significantly lower than that in patients with cSBP. According to the difference of bSBP and cSBP in each patient , Take individualized nursing interventions.
