Abstract [Objective]To explore the effects of dopamine plus phentolamine on infantile pneumonia com‐plicated with heart failure and myocardial enzyme so as to provide rationales clinical diagnosis and treatment .[Methods]A total of 114 children with pneumonia complicated with heart failure were randomly divided into two groups of control (A ,n =57) and observation (B ,n =57) .The control group received phentolamine a‐lone for 7 days while the observation group had both phentolamine and dopamine for 7 days .[Results]The o‐verall treatment efficiency was significantly higher in group B than that in group A (92 .89% vs 77 .19% ) and the difference had statistical significance ( P <0 .05);In observation group after treatment ,the serum levels of lactate dehydrogenase and creatine kinase were significantly lower than those before treatment and control group after treatment .And the difference had statistical significance ( P <0 .05) .In observation group after treatment ,dyspnea ,cyanosis and rales disappeared .And failure to control time and hospital stay were signifi‐cantly shorter than those in control group .And the difference had significant statistical significance ( P <0 .05) .Neither group had an onset of marked adverse reactions .[Conclusion]The efficacy of dopamine plus phentolamine is definite for pneumonia in children with heart failure .And it improves patient enzymes and is worthy of wider applications .
