部分护理活动对急性心肌梗死早期心功能的影响

目的评价部分护理活动对急性心肌梗死(AMI)早期心肌耗氧量的影响。方法对50例AMI患者于入院72h内,在平静状态下、排便后、晨间护理、探视和教学查房后4个时间点测量血压、心率,计算心肌耗氧量(D-P)。结果在排便、晨间护理、探视和教学查房后D-P值增加显著,床上排便后D-P值最大,晨间护理时D-P值最小。结论AMI患者须给予严密监护,尽量减少不必要的教学查房、家属探视,晨间护理时避免搬动患者、转换床位,以减少心脏负荷,降低心功能损害。

Effect of the activities in nursing care on heart function of patients with acute myocardiac infarction at early stage.

Objective: To evaluate the effect of the activities in nursing care on oxygen consumption of myocardium of patients with acute myocardiac infarction (AMI) at early stage. Methods: Blood pressure and heart rate of 50 patients were taken and measured to calculate oxygen consumption of myocardium in the normal state at the right 4 time points after defecation, morning care, ward round and visiting within 72 hours of patient's hospitalization. Results: Rate-pressure product (RPP) increased markedly after defecation, morning care, ward round and visiting. Value of RPP was maximum after defecation in bed and minimum at the time when morning care was given. Conclusion: Close observation should be given to patients with AMI and much attention should be paid to reduce and avoid unnecessary ward round for teaching, morning nursing care and turning over so as to lighten patient's heart load and cardiac functional damage.
