心脏衰竭患者静脉泵入硝酸甘油时回血的干预研究

微量泵为护士的准确安全用药提供了方便1]。它是一种将药液精确、微量、均匀持续地泵入体内的新型泵力仪器,可保证药物持续泵入2]。临床上,心脏衰竭(心衰)患者常常需要用微量泵以较慢的速度泵入硝酸甘油,但在泵入硝酸甘油的过程中,由于速度较慢,常有血液回流/反流到输液管(简

An intervention study about preventing blood return when using nitroglycerin for patients with heart failure

ObjectiveTo investigate the effective method of preventing blood return when using nitroglycerin for patients with heart failure. Methods Using physiological saline solution or 5% glucose with nitroglycerin pumped into the same vein for patients at the same time, and then observed the condition of blood returning, recorded the critical drop-speed which can effective prevented blood return. Observed the influence of added solution on heart function of patients with heart failure. Results Pumped physiological saline solution or 5% glucose with nitroglycerin in the same time with the speed of 5ml/h can effective prevent the blood return, and the added solution can not influence the heart function for patients with heart failure significantly. Conclusion Pumped physiological saline solution or 5% glucose with nitroglycerin into the same vein at the same time can effective preventing the blood return, and the added solution can not influence the heart function for patients with heart failure significantly.
