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.
