[摘要] 目的 研究呼吸睡眠紊乱对慢性阻塞性肺疾病急性加重期(AECOPD)患者动脉血气的影响。方法 选取86例单纯AECOPD(AECOPD组)和27例重叠综合征(OS)患者(OS组),分别在入院及出院时抽动脉血,比较动脉血气的变化特点。结果 OS组治疗前后动脉血pH、动脉血氧分压(PaO2)和动脉血氧饱和度(SaO2)均低于AECOPD组(P2饱和度(PaCO2)均高于AECOPD组(P<0.05)。AECOPD组治疗后动脉血pH、PaCO2、PaO2和SaO2均基本恢复正常,而OS组PaCO2及PaO2仍未能恢复正常,两组间比较差异有统计学意义(P<0.05)。结论 睡眠呼吸紊乱是造成OS患者高碳酸血症及缺氧难以纠正的重要原因。

Abstract:Objective To explore the impact of sleep apnea hypopnea on arterial blood gas of the patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Eighty six AECOPD patients and 27 OS patients were selected as cases to be studied,the changes of whose arterial blood gas are compared both when they are admitted and discharged.Results The value of pH, PaO2, SaO2of all OS patients were lower than those of AECOPD patients, and PaCO2 was higher than those of AECOPD patients. Even though pH, PaCO2, PaO2, SaO2 of AECOPD patients were restored to their original conditions after treatment, hypercapnia and relatively low oxygen saturation continued to exist in OS patients.The difference between the two groups is statistically significant.Conclusion Sleep apnea hypopnea is one of the most important factors for exacerbating hypoxemia,carbon dioxide retention and acidosis.
