不同促排便措施对早期急性心肌梗死病人心肌耗氧量的影响

目的]了解不同促排便护理干预措施对早期急性心肌梗死（AMI）病人排便过程中不同时段心肌耗氧量（MVO2）的影响,为临床采取合理、有效的促排便护理干预措施,减少排便时严重并发症的发生提供依据。方法]将28例需采用促排便护理干预措施的早期AMI病人随机分为开塞露组和蓖麻油组,采用多功能心电监护仪记录两组病人排便过程中心率和血压,并比较两组病人排便过程中不同时段心率、血压及MVO2变化。结果]两种促排便措施效果差异无统计学意义。开塞露组病人在促排便后心率和MVO2较蓖麻油组同期升高,其他时段两组病人心率、血压及MVO2无统计学意义。结论]在开塞露肛注后等待排便期间,病人MVO2较蓖麻油口服者增加,不宜过多延长开塞露肛注后等待排便的时间。促排便措施的选择应视病人具体情况而定。

Influence of different promoting defecation measures on myocardium oxygen consumption of early stage of acute myocardial infarction patients

Objective： To find out the influence of different promoting defecation intervention measures on oxygen consumption of myocardium of early stage acute myocardial infarction （AMI） patients in different time periods of defecation, to provide some bases for taking reasonable and effective promoting defecation nursing intervention measures, so as to decrease the occurrence of severe complications of AMI patients during defecation in clinic. Method： A total of 28 early stage of AMI patients who need to take promoting defecation nursing intervention were randomly divided into Kaiselu group and castor oil group. Heart rate, blood pressure and MVO2 of the two group cases were recorded by using multifunctional electrocardiogram monitor. And changes of heart rate, blood pressure and MVO2 of the two group patients at different time periods of defecation were compared. Results： There was no significant difference in terms of promoting defecation effect between the two groups. Both heart rate and MVO2 in patients of Kaiselu group elevated more obviously than that of patients in castor oil group after defecation. And there was no statistical significant difference in terms of heart rate and MVO2 at other time periods. Conclusion： During the period of waiting for defecation after Kaiselu anal injection, the MVO2 of patients elevated more obvious than that of patients oral taking castor oil. It is inadvisable to prolong waiting time for defecation in AMI patients after Kaiselu anal injection. The choice of promoting defecation measures should depend on individual condition of patients.
