不同吸氧方法治疗自发性气胸效果比较

目的探讨不同吸氧方法治疗自发性气胸的效果。方法 42例自发性气胸患者分为高流量吸氧组与低流量吸氧组,高流量吸氧组吸氧流量5~6 L/min,每次1小时,每天2次;低流量吸氧组吸氧流量2~3 L/min,每天吸氧时间〉12小时。结果两种吸氧方法对自发性气胸均有显著疗效,治疗前后肺压缩程度、动脉氧分压（PaO2）、氧合指数（PaO2/FiO2）差异有统计学意义（P〈0.01）;高流量吸氧组气胸吸收较低流量吸氧组快,对肺压缩的疗效较低流量吸氧组显著,差异有统计学意义（P〈0.01）。结论自发性气胸进行保守治疗时,短时间高浓度吸氧对肺压缩的疗效优于长时间低流量吸氧。

Clinical effect of different oxygen inhalation methods for spontaneous pneumothorax

Objective To evaluate the clinical effect of different oxygen inhalation Methods for spontaneous pneumothorax.Methods Records of 42 patients with spontaneous pneumothorax were divided into the high oxygen flow group and the low oxygen flow group.Oxygen flow in high oxygen flow group was 5~6 L/min（1 h for once a time,twice a day）.Oxygen flow in low oxygen flow group was 2~3 L/min（oxygen daily time 12 hours）.Results Both the two oxygen inhalation Methods had significant effect of spontaneous pneumothorax.The lung compression degree,PaO2,PaO2/FiO2 in the two groups improved significantly after oxygenation.Those Results before and after treatment had significant difference（P 0.01）.Absorption of gas in high oxygen flow group was faster than that in low oxygen flow group.Effect of lung compression degree in high oxygen flow group was more significantly than that in low oxygen flow group（P 0.01）.Conclusion The short-term and high-concentration oxygen inhalation is more effective than long-term and low-concentration oxygen inhalation in conservative treatment of spontaneous pneumothorax.
