无创通气对慢性阻塞性肺病患者夜间低氧血症的疗效观察

目的 观察双水平正压(BiPAP)无创通气治疗慢性阻塞性肺疾病(COPD)患者夜间低氧血症效果.方法 用多睡眠监测仪筛选出稳定期COPD夜间低氧患者82例,夜间睡眠用双水平正压无创通气治疗14天,第14天夜间用多睡眠监测仪再次进行睡眠监测.比较治疗前后的夜问血氧情况、睡眠结构变化.同时分别检测患者治疗前1天和治疗第14天的血清白细胞介素6(IL-6)情况.结果 稳定期COPD夜间低氧惠者夜间睡眠用无创通气治疗后,其平均血氧饱和度(SaO2)治疗前为(85.01±5.61)% vs第14天(92.12±6.81)%和最低SaO2治疗前为(65.23±6.91)%vs第14天(87.02±7.64)%明显增加,SaO2低于90%占睡眠总时间(T90)治疗前为(50.13±8.11)%vs第14天为(10.24±4.11)%明显减低.睡眠结构恢复正常.血清IL-6从治疗前(34.21±4.62)ng/L,治疗第14天减少为(18.60±6.42)ng/L(P<0.01).结论 无创通气是治疗COPD稳定期患者夜间低氧血症的有效方法.

Effects of BiPAP on nocturnal hypoxemia in patients with chronic obstructive pulmonary disease

Objective To observe the effect of bi-level positive airway pressure(BiPAP) therapy on nocturnal hypoxemia in patients with chronic obstructive pulmonary disease(COPD).Methods Eighty-two COPD patients proved to be nocturnal hypoxemia in stable stage by polysomnogram(PSG) for 7 hours at night.After 14 days BiPAP therapy,patients were monitored by PSG at 14th night in BiPAP therapy again,and compared on nocturnal hypoxemia and sleep structures before BiPAP therapy and 14th night BiPAP therapy.Blood serum IL-6...
