摘要目的 探讨护理干预对原发性高血压患者动态血压参数及血压昼夜节律的影响.方法 选择住院治疗的原发性高血压患者247例,按随机数字表法随机分为干预组123例和对照组124例,干预组实施护理干预,对照组接受心内科常规护理；比较两组患者治疗前后动态血压参数及血压昼夜节律的变化.结果 干预前两组患者动态血压参数比较差异均无统计学意义(P＞0.05)；干预后干预组24 h SBP、24 h DBP分别为(121.6±9.7),(82.7±7.9) mm Hg,均低于对照组的(124.7±10.1),(84.3±8.1)mm Hg,差异有统计学意义(t值分别为2.301,1.968;P ＜0.05)；两组患者其他动态血压参数比较差异均有统计学意义(P＜0.05)；干预组患者治疗后勺型血压比例较前升高,血压晨峰发生率下降,与治疗前相比,差异有统计学意义(P＜0.05)；与对照组相比,差异有统计学意义(x2值分别为4.023,4.562;P ＜0.05).对照组患者干预前后勺型血压、血压晨峰发生率比较差异有统计学意义(P＜0.05).结论 护理干预能显著改善原发性高血压患者血压昼夜节律,具有显著的临床意义.

abstractsObjective To investigate the effect of nursing intervention on ambulatory blood pressure and circadian rhythm of blood pressure in patients with essential hypertension.Methods 247patients with essential hypertension were chosen and randomly divided into the intervention group (n =123) and the control group (n =124).The intervention group received nursing intervention while the control group received regular nursing.Parameters of ambulatory blood pressure and changes in circadian rhythm of blood pressure were compared between two groups before and after treatment.Results Before intervention,there was no statistically significant difference in parameters of ambulatory blood pressure between two groups (P ＞ 0.05).After intervention,SBP and DBP in 24 h were (121.6 ± 9.7) and (82.7 ± 7.9) mm Hg in the intervention group,both lower than (124.7 ± 10.1) and (84.3 ± 8.1) mm Hg in the control group,and the differences were statisticallysignificant (t =2.301,1.968,respectively; P ＜ 0.05).Other parameters of ambulatory blood pressure also had statistically significant differences between two groups (P ＜ 0.05).Compared with before,the proportion of dipper blood pressure raised and the incidence rate of morning blood pressure surge decreased in both groups after treatment,with statistically significant differences (P ＜ 0.05),and the changes were more obvious in the intervention group than in the control group (x2 =4.023,4.562,respectively ; P ＜ 0.05).Conclusions Nursing intervention can significantly improve circadian rhythmof blood pressure in patientswith essential hypertension and hasremarkable clinical significance.
