[Abstract] Objective To analyze the clinical efficacy of low-dose dopamine in the treatment of neonatal asphyxia induced renal damage. Methods A total of 150 children with neonatal asphyxia induced renal damage admitted to our hospital from April 2017 to April 2019 were enrolled in the study and evenly divided into the control group and the observation group according to the parity of admission sequence, with 75 children in each group. The control group was treated with routine clinical treatment while the observation group was treated with low-dose dopamine on the basis of the control group. Both groups were treated for 7 days. The clinical efficacy, the urea nitrogen and creatinine levels, MAP, HR and PEF before treatment and after 7 days of treatment, and the incidences of complications of the two groups were compared. Results After 7 days of treatment, the total effective rate of the observation group(97.33%) was higher than that of the control group(81.33%), with statistically significant difference(P<0.05). Before treatment, the differences in urea nitrogen and creatinine levels between the two groups were not statistically significant(P>0.05), but after 7 days of treatment, the urea nitrogen and creatinine levels of the observation group were significantly lower than those of the control group, with statistically significant differences(P<0.05). The urea nitrogen and creatinine levels after 7 days of treatment were significantly lower than those before treatment in both groups, with statistically significant differences(P<0.05). Before treatment, the differences in MAP, HR and PEF between the two groups were not statistically significant(P>0.05), but after 7 days of treatment, the MAP, HR and PEF of the observation group were significantly higher than those of the control group, with statistically significant differences(P<0.05). The MAP, HR and PEF after 7 days of treatment were significantly higher than those before treatment in both groups, with statistically significant differences(P<0.05). The incidence of complications in the observation group(2.67%) was lower than that in the control group(13.33%), with statistically significant difference(P<0.05). Conclusion Low-dose dopamine can effectively alleviate the conditions of children with neonatal asphyxia induced renal damage, promote the returning of indexes such as urea nitrogen and creatinine, and effectively prevent complications such as renal dysfunction, which shows remarkable efficacy and is worth learning.
本研究结果显示,观察组临床总有效率、MAP、HR、PEF明显比对照组高,观察组治疗后7 d后尿素氮、肌酐水平、并发症发生率显著比对照组低(P<0.05)。与贾焕奇[11]研究结果接近,其研究结果发现研究组治疗后血尿素氮、血肌酐水平均显著比对照组低(P<0.05),提示小剂量多巴胺在新生儿窒息后肾损害治疗中安全、有效。分析原因如下:多巴胺属于内源性儿茶酚胺药物,可刺激心脏β受体产生作用,提高心脏β受体兴奋性,加快心率,促进血压、心率等生命体征复常[12-13]。另外,多巴胺可增加心输出量,具有扩张肠系膜血管、兴奋血管中受体等作用,在低心排出量伴随肾功能损伤等疾病治疗中取得了显著效果[14-15]。多巴胺也是人体重要的一种神经传导物质,主要由人体脑细胞分泌而来,多巴胺通过静脉泵注,结合多巴胺受体,可有效增加肾血管流量,扩大肾脏血管,增强肾小球的滤过率,促进钠离子以尿量排泄,可有效预防肾脏缺血现象发生,降低肾脏功能障碍发生率[16]。由于新生儿年龄较小,因此选择小剂量的多巴胺,可缓解患儿临床症状,改善肾脏功能的同时降低不良反应,安全性更高,可作为新生儿窒息后肾损害的首选药物。本研究创新之处在于研究小剂量多巴胺治疗新生儿窒息后肾功能损害患儿,可促进心率、血压、气道峰压复常,为研究小剂量多巴胺在新生儿窒息后肾损害治疗中的临床疗效提供更加科学的参考依据。
综上所述,新生儿窒息后肾损害患儿采用小剂量多巴胺治疗,可有效缓解患儿紫绀等症状,促进血压、心率升高,降低尿素氮、肌酐水平,有效预防肾功能障碍等并发症发生,取得良好的治疗效果,值得进一步推广。
