目的:探讨高压氧治疗毛细支气管炎的疗效。方法:毛细支管炎患儿84例,随机分为治疗组和观察组。治疗组在综合治疗基础上,给予高压氧治疗,每日治疗1次,3次为1疗程。观察高压氧治疗前后患儿呼吸频率(R)、心率(HR)、血PH值、动脉血氧分压(PaO2)、二氧化碳分压(PaCO2)、肺部罗音变化。结果:高压氧治疗组患儿PH、PaO2、PaCO2均较治疗前明显好转,与对照组比较有显著性差异(P<0.05)。呼吸急促、喘憋、心动过速等症状缓解以及肺部罗音的吸收与对照组比较有显著性差异(P<0.05)。结论:高压氧治疗可以改善毛细支气管炎患儿肺泡通气和换气功能,促进肺部罗音吸收。
Objective: To investigate the effect of hyperbaric oxygen therapy on bronchiolitis. Methods: Eighty-four children with benign bronchitis were randomly divided into treatment group and observation group. On the basis of comprehensive treatment, the treatment group was given hyperbaric oxygen therapy, once daily and 3 times as a course of treatment. The changes of respiratory rate (R), heart rate (HR), blood PH, PaO2, PaCO2 and pulmonary rales were observed before and after hyperbaric oxygen therapy. Results: The levels of PH, PaO2 and PaCO2 in hyperbaric oxygen treatment group were significantly improved compared with those before treatment, and there was significant difference between the two groups (P <0.05). Shortness of breath, wheezing, tachycardia and other symptoms relieved and pulmonary rales absorption compared with the control group were significantly different (P <0.05). Conclusion: Hyperbaric oxygen therapy can improve alveolar ventilation and ventilation in children with bronchiolitis and promote pulmonary rales absorption.
