高血压患者卧立位试验中断的相关因素分析

目的分析高血压患者进行卧立位试验时中断的相关因素,为预防患者晕倒造成伤害提供参考依据。方法将2011年1—12月在我院接受卧立位试验的89例患者根据试验是否顺利进行分组,试验中出现明显不适体征或者晕倒者做为观察组(20例);未出现任何明显症状者做为对照组(69例)。比较两组患者年龄、性别、体质量指数、血钾、高血压病史、卧立位血压差以及服药史等方面的差异。结果观察组以女性居多(P0.01),年龄偏大(P0.05);观察组的收缩压差与舒张压差均明显高于对照组(P0.01);两组体质量指数、血钾、是否有高血压病史以及服药史的比较,差异无统计学意义(P0.05)。结论女性、年龄偏大患者、卧立位血压差较大患者更加容易出现晕厥,导致卧立位试验中断,对该类患者应该有针对性地进行重点护理。

Risk Factors of Disruption of Recumbent-upright Test

Objective To analyze risk factors of disruption of recumbent-upright test, and to provide theoretical basis for preventing harm in the test. Methods Clinical data about 89 patients in recumbent-upright test from January to December in 2011 were retrospectively analyzed. Patients were divided into observation group including patients showed uncomfortableness or syncope in the test and control group with those accomplishing the test successfully. Their differences on age, gender, BMI, serum potassium, the postural difference of blood pressure, and the history of hypertension and taking medicine were compared. Results Most of the patients included in observation group were females（P〈0.01） or the elderly（P〈0.05）; the level of systolic blood pressure difference and diastolic blood pressure difference were significantly higher in observation group than those in control group（P〈0.01）. Significant difference was not found between these two groups in BMI, serum potassium and the history of hypertension and taking drugs. Conclusion Female patients, elderly patients or those with significant postural difference of blood pressure are more prone to syncope, leading to disruption of recumbent-upright test. Those patients should be targeted for main nursing care.
