摘  要:目的探讨无创正压通气(NIPPV)对夜间慢性阻塞性肺疾病(COPD)患者呼吸力学和睡眠紊乱的影响。方法选择南方医科大学珠江医院呼吸内科自2010年10月至2011年10月收治的COPD急性加重期住院患者16例,常规肺通气功能测定,经过NIPPV治疗病情稳定后,分别在患者自主呼吸和NIPPV时睡眠状态下进行呼吸力学和多导睡眠图的监测,连续采集并计算各项呼吸和睡眠参数。结果COPD患者睡眠状态下,NIPPV与自主呼吸相比较,呼吸频率(RR)差异无统计学意义(JP〉0.05);潮气量(Vt)由(0.35±0.10)L升高到(0.45±0.12)L、每分钟通气量(vE)由(6.17±1.15)L/min升高到(7.97±2.34)L/min、平均吸气流量(VT/Ti)由(0.24±0.09)L/s升高到(0.39±0.11)L/s、动态肺顺应性(CLdyn)由(43.46±12.75)ml/cmH20(1emH20=98Pa)升高到(60.23±17-31)ml/cmH20、指脉氧饱和度(Sp02)由(83.55±5.07)%升高到(95.67±5.38)%,差异均有统计学意义(P〈0.05~P〈0.001);吸气时间占呼吸周期比值(Ti/Ttot)由0.43±0.11降低到0.33±0.08、气道阻力(Raw)由(25.64±6.02)cmH20/L。百。降低到(20.34±3.67)cmH20/L~1S-1、压力一时间乘积(PTP)由(423.12±89.06)amH20-s叫·rain“降低到(170.44±41.53)cmH20·S-1·min-1、呼气末二氧化碳分压(PETC02)由(63.74±8.45)mmHg(1mmHg=0.133kPa)降低到(45.32~5.74)mmHg,差异均有统计学意义(P〈0.05~P〈0.001)。睡眠效率(SEF%)由(74.23±12.78)%升高到(84.41±15.11)%、快速动眼睡眠时间占总睡眠时间百分比(REMfrST%)由(12.16±7.38)%升高到(19.35±9.41)%、慢波睡眠占总睡眠时间百分比(SWS/TST%)由(5.38±3.35)%升高到(13.68±7.25)%、夜间基础指脉氧饱和度(SpOz%base)由�Objective To determine the effects of nighttime noninvasive positive pressureventilation (NIPPV) on respiratory mechanics and sleep disorders in patients with chronic obstructive pulmonary disease (COPD). Methods Sixteen moderate to severe COPD patients during acute exacerbation admitted in Zhujiang Hospital, Southern Medical University, between October 2010 and October 2011 were enrolled in the study. Following spirometry, all the patients who were clinically stable after NIPPV treatment were subjected to respiratory mechanics monitoring and polysomnography (PSG) while breathing spontaneously or receiving NIPPV during sleeping, for capturing various respiratory and sleep-associated parameters. Results The respiratory rate (RR) did not differ statistically in patients treated with NIPPV as compared to spontaneous breath during sleep (P〉0.05). There were significant increases (all P〈0.05) in tidal volume(VT) [ (0.35±0.10)L vs (0.45±0.12)L], minute ventilation (VE) [ (6.17±1.15) ldmin vs (7.97± 2.34) L/mini , mean inspiratory volume (vTgri) [ (0.24±0.09) L/s vs (0.39±0.11) L/s] , dynamic lung compliance (CLdyn) [ (43.46± 12.75) ml/cm H20 ( 1 cm H20=98 Pa) vs (60.23 ± 17.31 ) ml/cm H20] and pulse oxygen saturation(SpO2) [ (83.55±5.07)% vs (95.67±5.38)% ] in NIPPV treatment as compared to spontaneous breath state during sleep. While marked reductions (all P〈0.05) were found in the ratio of inspiratory time to single respiratory cycle(Ti/Ttot) [ (0.43±0.11 ) vs (0.33±0.08) ], airway resistance (Raw) [ (25.64±6.02) cm H20/L-l .s-1 vs (20.34±3.67) cm H20/L-1 -s-j ], pressure-time product (PTP) [ (423.12± 89.06 cm H20- s/min vs (170.44±41.53) cm H20- s/rain] and end tidal carbon dioxide partial pressure (PrrCO2) [ (63.74±8.45) mm Hg(1 mm Hg=0.133 kPa) vs (45.32±5.74) mm Hg]. In addition, significant increases(all P〈0.05) were present in sleep efficienc
