目的探讨氧气驱动雾化吸入疗法治疗小儿肺炎疗效。方法 2010年8月至2012年8月收治的小儿肺炎180例分为超声雾化组90例,氧气驱动组90例,观察两组临床疗效。结果超声雾化组总有效率64.44%,氧气驱动组总有效率92.22%,两组总有效率比较差异有统计学意义(P<0.05)。结论氧气驱动雾化吸入是以高压纯氧经过雾化吸入器将药液喷射撞击成小气雾颗粒,形成的气雾颗粒表面携带氧和药液,不会造成气体氧浓度下降,并且能够增加气体氧浓度,促进气体交换,提高氧的有效弥散及肺泡血流的氧合效率改善患者低氧血症,解除支气管痉挛、减轻水肿、通畅气道的治疗目的。总之,氧气驱动雾化吸入临床疗效优于超声雾化吸入,能够显著改善临床症状,纠正低氧血症,特别适合于存在缺氧患儿应用。
Objective To investigate the therapeutic effect of aerosol-driven inhalation therapy on children with pneumonia. Methods One hundred and eighty children with pneumonia admitted from August 2010 to August 2012 were divided into 90 cases of ultrasonic atomization group and 90 cases of oxygen driven group. The clinical curative effect was observed. Results The total effective rate was 64.44% in the ultrasonic atomization group and 92.22% in the oxygen-driven group. There was significant difference between the two groups in the total effective rate (P <0.05). Conclusion Oxygen-driven aerosol inhalation is the high-pressure pure oxygen through the atomizer inhaler spray into the small aerosol particles, aerosol particles formed on the surface carrying oxygen and liquid, will not cause the gas oxygen concentration decreased, and can increase the gas Oxygen concentration, promote gas exchange, improve the effective diffusion of oxygen and oxygenation efficiency of alveolar flow in patients with hypoxemia, relieve bronchial spasm, reduce edema, smooth airway treatment purposes. In conclusion, oxygen-driven nebulization has superior clinical efficacy to nebulized inhalation, which can significantly improve clinical symptoms and correct hypoxemia, especially for children with hypoxia.
