持续气道正压无创呼吸机治疗小儿重症肺炎并发急性呼吸衰竭的临床效果

Clinical effect of continuous positive airway pressure non-invasive ventilator in the treatment of severe pneumonia complicated with acute respiratory failure in children

目的评价重症小儿肺炎并发急性呼吸衰竭(ARF)用持续气道正压无创呼吸机(CPAP)治疗的效果。方法选取2013年10月~2019年8月我院收治的70例重症小儿肺炎并发ARF患儿作为研究对象,按照计算机随机分组法分为对照组(n=35)与治疗组(n=35)。对照组采用鼻导管吸氧治疗,治疗组采用持续气道CPAP,比较两组血气指标、呼吸频率、心率、症状缓解时间、治疗总有效率。结果治疗组动脉血氧分压高于对照组,动脉血二氧化碳分压低于对照组(P<0.05);治疗组呼吸频率与心率低于对照组(P<0.05),治疗组症状缓解时间短于对照组(P<0.05)。治疗组治疗总有效率高于对照组,差异有统计学意义(P<0.05)。结论在重症小儿肺炎并发ARF患儿临床治疗中,持续气道CPAP治疗效果显著,既可改善血气指标及呼吸频率与心率,又能缩短症状缓解时间、提高临床效果,临床应用价值较高,值得推广。

Objective To evaluate the effect of continuous airway pressure non-invasive ventilator(CPAP)in patients with severe pediatric pneumonia complicated with acute respiratory failure(ARF).Methods Seventy children with severe pediatric pneumonia complicated with ARF admitted to our hospital from October 2013 to August 1919 were selected as research objects.They were divided into the control group(n=35)and treatment group(n=35)according to computer randomization.The control group was treated with nasal cannula oxygenation.The treatment group was treated with continuous positive airway pressure CPAP.The blood gas index,respiratory rate and heart rate,time to symptom relief,and total effective rate were compared between the two groups.Results The arterial partial pressure of oxygen in the treatment group was higher than that in the control group,the partial pressure of arterial blood carbon dioxide was lower than that of the control group(P<0.05).The respiratory rate and heart rate of the treatment group were lower than those of the control group(P<0.05).The symptom relief time of the treatment group was lower than that of the control group,the difference was statistically significant(P<0.05).The total effective rate of the treatment group was higher than that of the control group,the difference was statistically significant(P<0.05).Conclusion In the clinical treatment of severe pediatric pneumonia complicated with ARF,continuous positive airway pressure CPAP has a significant effect on improving blood gas index,respiratory rate and heart rate,shortening symptom relief time and improving clinical efficacy.The clinical application value is high and worth promoting.
