心阻抗法无创心排量测定对心力衰竭患者分级护理的指导研究

Guidance of grading nursing care by impedance cardiography in patients with heart failure

目的分析心阻抗(ICG)无创心排量测定对心力衰竭患者分级护理的指导效果。方法选取2013年2月至2015年8月收治的100例慢性心力衰竭患者为研究对象,随机均分为对照组和观察组,每组50例。对照组行超声心动图测定,观察组行ICG无创心排量测定。结果观察组疗效明显优于对照组,差异有统计学意义(χ~2=9.490,P<0.05);观察组护理满意度明显高于对照组,差异有统计学意义(χ~2=7.111,P<0.05)。治疗前2组患者的CI、CEF和CO差异无统计学意义(P>0.05)。2组治疗后的CI、CEF和CO较治疗前显著提高(P<0.05),且观察组明显优于对照组(P<0.05)。治疗后,患者MAP指数均较治疗前明显下降,差异有统计学意义(P<0.05);2组患者HR指数较治疗前均明显上升,但对照组HR指数上升幅度明显大于观察组,差异有统计学意义(P<0.05)。观察组患者不良反应发生率为6.00%,对照组不良反应发生率为30.00%,2组不良反应情况差异有统计学意义(P<0.05,χ~2=7.862)。结论对慢性心力衰竭急性失代偿患者进行护理过程中,加入ICG无创心排量测定,可起到有效的治疗指导意义,大幅度提升治疗效果,促进患者早日康复。

Objective To investigate the directive effects of impedance cardiography(ICG)on grading nursing care in patients with heart failure.Methods One hundred patients with chronic heart failure who were admitted and treated in our hospital from February 2013 to August 2015 were randomly divided into control group and observation group.The patients in control groups received ultrasoundcardiogram examination,however,the patients in observation group received ICG examination,then the HR(heart rate),CI(cardiac index),CO(cardiac output),EF(ejection fraction)and MAP(mean arterial pressure)were observed and compared between the two groups.Results The therapeutic effects in observation group were superior to those in control group(χ^2=9.490,P<0.05),and the nursing satisfaction degree in observation group was significantly higher than that in control group(χ^2=7.111,P<0.05).Conclusion During grading nursing for patients with chronic heart failure at acute decompensation period,ICG can improve the HR,CI,CO,EF and MAP of patients,so as to inprove the therapeutric effects and promote early rehabilitation of patients.
