摘　　要：目的探讨解决心脏衰竭(心衰)患者在静脉泵入硝酸甘油时出现的静脉血反流或回血的方法。方法在静脉泵入硝酸甘油的同时,以一定的速度从同一静脉通路输入生理盐水或5%葡萄糖至硝酸甘油泵完,观察回血情况及能阻止静脉血反流的最慢滴速,并观察额外输液,对患者心功能的影响。结果静脉泵入硝酸甘油的速度<5ml/h时出现回血,以5次/min的速度维持输液即可阻止回血。与无回血未施干预的对照组相比,观察组患者在泵入硝酸甘油时伴随的额外输液对患者的心功能未产生明显的影响。结论静脉泵入硝酸甘油的同时以一定的速度从同一通路缓慢滴入生理盐水或5%葡萄糖即可以阻止回血,同时额外增加的输液并不增加心衰患者心脏负担。Objective To 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 influenee 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 retum, and the added solution can not influence the heart function for patients with heart failure significantly.
