慢性阻塞性肺病急性加重期肾功能损害的研究
[摘要] 目的研究慢阻肺(COPD)急性加重期肾功能损害的特点。方法观察20例COPD(分A、B两组)急性加重期肾功能的变化,与普通肺炎(C组)进行比较。结果急性期所有患者氧分压下降,r)降低,r上升,与治疗前相比有显著差异(P<),A组与治疗前相比无显著差异(P>)。COPD伴急性呼衰时,随Ccr降低,血浆肾素分泌增强。严重缺氧导致尿钠排泄下降,尿量减少。高碳酸血症时症状加重,可并发急性肾衰。结论急性呼衰为COPD肾功能损害的主要原因。

Study on Clinical Features of Impairment of Renal Function in the Patients with Chronic Obstructive Lung Diseases in Exacerbations
[Abstract] Objective To study the clinical features on impairment of renal function in patients with chronic obstructive pulmonary disease (COPD) in exacerbations. Methods The changes of renal function in 20 patients with COPD which were dividend into A and B group in exacerbations were observed and pared mon pneumonia group (group C). Results Arterial blood oxygen tension (PaO2) and creatinine clearance rate (Ccr) were found decreasing with different grades in all patients. A rapidly increase r was seen in group C after oxygen therapy (P<). The change r in patients (group A) was no obvious after therapy (P>). The level of plasma renin rose with the decline r when the patients with COPD had developed acute respiratory failure. Severe hypoxia did greatly decrease Na+and water excretion. The clinical symptoms might deteriorated when patients suffered hypercapnia, and acute renal failure could thus develop. Conclusion Acute respiratory failure played a main rol
