急性心肌梗死患者24小时出入量统计与便秘相关性的研究

目的观察性分析24小时总出入量对AMI患者便秘的影响,研究生理需要量、出入平衡与便秘间的关系。方法回顾264例心内科CCU病房AMI患者（Killip分级在Ⅰ-Ⅱ级）生理需要量、出入量平衡与便秘的发生率。方法如下：（1）按24小时总入量与生理需要量间的关系随机分为2组,A组159例,其24小时总入量大于等于生理需要量,B组105例,其24小时总入量小于生理需要量。（2）按出入平衡,随机分为C组150例为正平衡组,D组114例为负平衡组。结果 （1）A组便秘的发生率为47.2%,B组便秘的发生率为65.7%,A组低于B组（P〈0.05）;（2）C组便秘的发生率为46.0%,D组便秘的发生率为60.5%,C组低于D组（P〈0.05）。结论 24小时出入量与便秘具有相关性,24小时出入量的统计有助于便秘风险的评估,对临床预防便秘的发生具有指导意义。

Objective To observe the impact on constipation of the total intake and output volume in 24 hours of acute myocardial infarction （AMI） patients,and investigate the relationships between the physiological requirements,intake and output balance and constipation.Methods Collect 264 AMI patients （Killip grade levelⅠ-Ⅱ） in CCU which were admitted.Retrospectively analyze the incidence of constipation under the different physiological requirements and intake and output balance.The groups were as follows：（1）The patients were randomly divided into group A （159 patients） and group B （105 patients） according to the relationship between physiological requirement and total intake volume in 24 hours.Total intake volume in 24 hours was equal or greater than physiological requirement in group A while that was contrary in group B.（2）The patients were randomly divided into group C （150 patients） and group D （114 patients） according to the intake and output balance.Group C was positive balance group while group D was negative balance one.Results （1）The incidence of constipation in group A is 47.2% while that in group B is 65.7%,group A〈group B （P〈0.05）.（2）The incidence of constipation in group C is 46.0%,while that in group D is 60.5%,group C〈group D （P〈0.05）. Conclusion The total intake and output volume in 24 hours is related with constipation.Volume calculation is helpful to evaluate the wish and guide the clinical prevention of constipation.
