摘要
目的观察持续低流量吸氧对老年慢性充血性心力衰竭的治疗作用。方法观察老年慢性充血性心裹患者28例，心功能Ⅱ－Ⅳ，除常规强心、扩血管及利尿治疗外，根据吸氧条件的不同，随机分成两组：氧疗组，12例，夜间持续低流量鼻导管吸氧，1～2L／min，10－14h／d；对照组，16例，间断低流量吸氧，30min／次，2次／d。两组患者一般情况无明显差异。4周后比较两组患者的临床症状及心功能情况。结果氧疗组临床症状明显改善，心率显著下降。结论持续低流量吸氧可显著降低慢性充血性心衰患者的心率，改善心衰临床症状。
Objective To observe the treatment of persistent inspiration of low-now oxygen for senile chronic congestive heart failure. Methods 28 cases suffering from senile chronic congestive heart failure were observed with heart function Ⅱ ~ Ⅳ. They were divided into two groups according to different duration of oxygen inspiration besides protocol routine therapies. Oxygen therapy group received persistent nasal catheter oxygen inspiration during night (1 ~ 2L/min, 10 ~ 14h/d, n = 12). The control group received intermittent oxygen inspiration (1 ~ 2L/min, 30min/per, 2/d). Clinic symptoms and cardiac function were compared afer 4 weeks. Results There was significant improvement of clinic symptoms and significant decrease of heart rates in oxygen therapy group but not in control group. Conclusion Persistent low flow oxygen therapy can significantly reduce the heart rate and improve the clinical symptoms of senile chronic congestive heart failure.
