慢性阻塞性肺疾病患者长期氧疗的效果分析

Effects of long - term oxygen therapy in patients with chronic obstructive pulmonary disease

目的 观察长期氧疗（LTOT）对慢性阻塞性肺病（COPD）患者的疗效。方法 对46例COPD稳定期患者进行3年的LTOT，于LTOT前后观察患者住院次数、呼吸困难改善情况、动脉血气分析及血浆白蛋白的变化情况。结果 氧疗后1、2、3年与氧疗前基础值比较，患者住院次数减少，呼吸困难等临床症状显著减轻，低氧血症改善，营养状况好转。结论 合理使用LTOT对COPD患者有良好的治疗作用，可提高患者生活质量。

Objective To observe the therapitic effects of Long- term oxygen therapy （LToT） in chronic obstructive pulmonary disease （COPD）. Methods Forty - six patients with COPD were underwent LTOT for 3 years. Their admission freguency, dyspnea amelioration,arterial blood gas analysis and plasma albumin were compared before and after LTOT. Results The admission frequency,dysponea,hypoxemia and nutritional status were obviously improved after LTOT. Conclusion The reasonable use of LTOT may achieve a good therapitic effects in patients with COPD and thus improve their quality of life.
