补充富钾饮食对老年住院冠心病患者排便困难的预防效果

Effect of Potassium-rich Diet on Constipation for Hospitalized Elderly with Coronary Heart Disease

目的探讨补充富钾食物预防老年冠心病住院患者排便困难的有效性。方法老年住院冠心病患者100例分为干预组(n=50)和对照组(n=50)。干预组每日补充橙汁400 ml(含K+600 mg),对照组每日补充白开水400 ml。记录两组7 d内排便情况。结果干预后,干预组排便次数较对照组明显增加(P<0.01),排便伴随症状评分、排便困难程度评分较对照组改善(P<0.05),住院期间主要心血管不良事件发生率无显著性差异(P>0.05)。结论补充富钾食物能够减少老年住院冠心病患者排便困难程度。

Objective To observe the effect of potassium-rich diet on constipation for elderly patients with coronary heart disease（CHD） during hospitalization.Methods 100 elderly CHD patients were divided into treatment group（n=50） and control group（n=50）.The treatment group drank orange juice 400 ml（about potassium 600 mg） per day,while the control group drank the same volume of water.Their defecation in 7 d was recorded.Results Compared with those in control group,the frequency of defecation increased（P0.01）,The Bleijenberg score and Bristol score both decreased（P0.05） in the treatment group.There was no significant difference in incidence of major adverse cardiac events between these groups（P0.05）.Conclusion Potassium-rich diet plays an important role in prevention of constipation in elderly patients with CHD during hospitalization.
