目的探讨间羟胺联合酚妥拉明在小儿肺炎合并心力衰竭中的应用效果。方法选择本院小儿肺炎合并心力衰竭患儿70例,随机分为观察组和对照组。两组患者均给予常规处理,对照组采用上述常规治疗,观察组在常规治疗基础上给予间羟胺联合酚妥拉明治疗。治疗后评定两组疗效。结果观察组患儿治疗后临床效果评定中,显效25例,占71.4%;有效9例,占25.7%;无效1例,占2.9%。观察组总有效率为97.1%。对照组患儿治疗后临床效果评定中,显效17例,占48.6%%;有效10例,占28.6%%;无效8例,占22.8%,对照组总有效率为77.2%。观察组总有效率高于对照组(P<0.05)差异具有统计学意义。结论间羟胺联合酚妥拉明在小儿肺炎合并心力衰竭中的应用效果显著,值得借鉴。 Objective To investigate the effect of m-hydroxylamine combined with phentolamine in children with pneumonia and heart failure. Methods Seventy children with pneumonia complicated with heart failure in our hospital were randomly divided into observation group and control group. The two groups of patients were given conventional treatment, the control group using the conventional treatment, the observation group on the basis of conventional treatment given melamine combined phentolamine treatment. After treatment, the two groups were evaluated. Results In the evaluation of clinical effect in treatment group, 25 cases were markedly effective, accounting for 71.4%; 9 cases were effective, accounting for 25.7%; 1 case was ineffective, accounting for 2.9%. The total effective rate of observation group was 97.1%. In the control group, the clinical effect was evaluated in 17 cases (48.6%), 10 cases (28.6%), 8 cases (22.8%), and the control group (77.2%). The total effective rate in the observation group was significantly higher than that in the control group (P <0.05). Conclusion The combination of hydroxylamine and phentolamine in children with pneumonia complicated with heart failure has a significant effect and is worth learning from.
