目的 分析自动三水平气道正压通气对伴高碳酸血症的重叠综合征患者的疗效.方法选择2012年10月至2014年5月就诊于南京医科大学第一附属医院呼吸科的21例PaCO2>45 mmHg(1 mmHg =0.133 kPa)的合并存在慢性阻塞性肺疾病(慢阻肺)和中-重度阻塞性睡眠呼吸暂停综合征(OSAS)的重叠综合征患者,采用SOMNOvent auto-S型无创呼吸机(德国Weinmann公司)治疗,比较3种不同通气模式的疗效,3种模式中吸气相气道正压(IPAP)值在每位患者中一致,均根据呼气末CO2滴定出,但呼气相气道正压(EPAP)不同,模式1和模式2均为固定的双水平气道正压通气模式,模式1的EPAP为能消除睡眠期鼾声的最低正压,而模式2的EPAP较模式1高3 cmH2O(1 cmH2O =0.098 kPa).模式3为自动三水平气道正压通气模式,EPAP的初期压同模式1,但EPAP末期压(EEPAP)为自动调节升压,每种模式均予以一夜间8h的治疗,不同模式治疗间间隔两夜未予治疗,分别比较与治疗前和不同模式治疗之间患者的睡眠期呼吸暂停低通气指数(AHI)、最低脉搏血氧饱和度(miniSpO2)、微觉醒指数、睡眠效率、治疗毕清晨PaCO2和治疗次日的Epworth嗜睡评分(ESS).结果 与治疗前相比,模式1~3治疗中AHI[(6.3±1.3)、(3.1±1.0)、(3.6±0.6)比(38.6±11.3)次/h]和微觉醒指数[(7.0±1.1)、(5.1±0.9)、(4.2±1.7)比(27.5±5.4)次/h]均显著降低,而miniSpO2[(82.3±5.4)、(89.6±3.9)、(90.3±3.2)比(62.4±11.3) mmHg]和睡眠效率[(71.3±5.2)%、(79.4±4.3)%、(83.2±4.4)%比(59.8±6.3)%)]均显著增高,治疗毕的PaCO2[(42.4±3.8)、(47.9±2.6)、(43.2±3.3)比(57.3±4.3)mmHg]和治疗结束当天的白日ESS[(7.2±1.3)、(7.4±1.3)、(5.3±1.5)比(11.4±2.7)分]也均显著降低(均P<0.01).3种模式中模式3治疗时的睡眠效率最高,治疗毕的白日ESS最低;与模式1相比,�
Objective To observe the efficacy of auto-trilevel positive airway pressure (Autotrilevel PAP) ventilation in overlap syndrome (OS) patients with hypercapnia.Methods From October 2012 to May 2014,21 OS patients with a PaCO2 〉 45 mmHg (1 mmHg =0.133 kPa) and coexisting stable chronic obstructive pulmonary diseases (COPD) and moderate-to-severe OSAS were recruited.Three different positive airway pressure (PAP) modes of ventilators (SOMNOvent auto-S,Weinmann Inc,Germany) were employed for 8 hours per night with each mode at each night and two nights' interval without any treatment among different modes.Under mode one,the expiratory positive airway pressure (EPAP)issued by bilevel positive airway pressure (BiPAP) was titrated as the minimal positive pressure for a disappearance of snoring.The same inspiratory positive airway pressure (IPAP) titrated by end tidal CO2 levels under mode 1 was used under modes 2 and 3 as well.However,the EPAP issued by BiPAP under mode 2 was 3 cmH2O (1 cmH2O =0.098 kPa) higher than that under mode 1.Under mode 3 with autotrilevel PAP,the beginning of EPAP was set the same as that under mode 1 while the end of EPAP (EEPAP) was automatically adjusted based on upper airway patency condition.Comparisons were made for parameters before and after treatment as well as among different ventilation modes.The following parameters were compared such as nocturnal apnea hypopnea index (AHI),minimal SpO2 (miniSpO2),arousal index,sleep efficiency,morning PaCO2 and Epworth sleepiness score (ESS).Results Compared with the parameters pre-therapy,modes 1-3 showed a significant decrease in nocturnal AHI (6.3 ± 1.3),(3.1 ±1.0),(3.6 ±0.6) vs (38.6 ± 11.3) events/h),arousal index ((7.0 ± 1.1),(5.1 ±0.9),(4.2 ±1.7) vs (27.5±5.4) events/h),morning PaCO2(42.4 ±3.8),(47.9±2.6) and (43.2±3.3) vs (57.3±4.3) mmHg and daytime ESS (7.2 ±1.3,7.4± 1.3 and 5.3 ±1.5 vs 11.4 ±2.7),but a signif
