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

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。

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

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(P<0.01),The Bleijenberg score and Bristol score both decreased(P<0.05) in the treatment group.There was no significant difference in incidence of major adverse cardiac events between these groups(P>0.05).Conclusion Potassium-rich diet plays an important role in prevention of constipation in elderly patients with CHD during hospitalization.
