To investigate the effect of nurse-led home-based biofeedback intervention on the blood pressure levels among patients with hypertension.
Nurse-led interventions are emerging as cost-effective as well as clinically proven in chronic illness management. Hypertension, a leading long-term cardiovascular condition, has autonomic dysregulation and increased sympathetic tone as its pathophysiological background. Complementary interventions evidenced to interplay hypertension pathophysiology.
A pretest-posttest design.
Uncomplicated primary hypertension outpatients were randomly assigned as study group ( = 173) and control group ( = 173) at a tertiary care hospital. Sociodemographic, clinical, and outcome variables [the baseline blood pressure and galvanic skin response (GSR)] were collected. Study group patients were given four teaching sessions of abdominal breathing-assisted relaxation facilitated by GSR biofeedback. Daily home practice was encouraged and monitored to measure the effects on blood pressure and GSR at the end of the 1, 2, and 3 month of intervention.
The study group participants showed significant decrease in mean (SD) systolic [140.77 (8.31) to 136.93 (7.96), = 469.08] and diastolic blood pressure [88.24 (5.42) to 85.77 (4.66), = 208.21]. In contrast, control group participants had a mild increase in the mean systolic ( = 6.02) and diastolic blood pressure ( = 4.70) values from pretest to posttests. GSR showed a significant increase from 559.63 (226.33) to 615.03 (232.24), ( = 80.21) from pretest to posttest III.
Use of home-based biofeedback-centered behavioral interventions enabled BP reduction among hypertensive patients. Further studies should use biochemical markers of sympathetic nervous system activity to endorse this home-based chronic illness intervention.
探讨以护士为主导的家庭生物反馈干预对高血压患者血压水平的影响。
以护士为主导的干预措施在慢性病管理中已被证明具有成本效益且临床效果良好。高血压是一种主要的长期心血管疾病，其病理生理背景是自主神经调节异常和交感神经张力增加。有证据表明，辅助干预措施可与高血压病理生理学相互作用。
前后测试设计。
在一家三级护理医院，将无并发症的原发性高血压门诊患者随机分为研究组（n = 173）和对照组（n = 173）。收集社会人口统计学、临床和结局变量[基线血压和皮肤电反应（GSR）]。研究组患者接受了四次由GSR生物反馈辅助的腹部呼吸辅助放松教学课程。鼓励并监测每日家庭练习，以测量干预1、2和3个月结束时对血压和GSR的影响。
研究组参与者的平均（标准差）收缩压[从140.77（8.31）降至136.93（7.96），F = 469.08]和舒张压[从88.24（5.42）降至85.77（4.66），F = 208.21]显著降低。相比之下，对照组参与者的平均收缩压（F = 6.02）和舒张压（F = 4.70）值从前测到后测略有增加。从测试前到测试III，GSR显著增加，从559.63（226.33）增加到615.03（232.24），（F = 80.21）。
以家庭生物反馈为中心的行为干预可使高血压患者血压降低。进一步的研究应使用交感神经系统活动的生化标志物来支持这种家庭慢性病干预措施。
