摘要 目的研究单肺移植手术治疗慢性阻塞性肺疾病(COPD)对呼吸生理及肺功能的影响。方法5例患者均为Ⅳ级COPD男性患者,年龄51~63岁。术前2周测定患者用力肺活量(FVC)、第一秒用力呼气容积(FEV1)、FEV1/FVC、最大通气量(MVV)、残气容积(RV)、肺总量(TLC)、残总比(RV/TLC)、深吸气量(IC)、胸腔气体容积(TGV)、呼气峰流量(PEF)、总气道阻力(Rawtotal)、肺一氧化碳弥散量(DLCO)、每升肺泡容积肺一氧化碳弥散量(DLCO/V·A)、6分钟行走距离(6MWD)、动脉血氧分压(PaO2)、肺泡气动脉血氧分压差[P(Aa)O2]、动脉血氧饱和度(SaO2)、动脉血二氧化碳分压(PaCO2)及平均肺动脉压(mPAP)等参数。术后2个月再行上述测定。结果5例患者术前2周、术后2个月检测的参数为MVV(23.6±5.8)、(71.6±21.8)L,FEV1(0.68±0.21)、(1.85±0.46)L,FEV1/FVC(37.4±8.3)、(75.6±13.9)%,PaO2(60.0±9.1)、(86.2±2.9)mmHg(1mmHg=0.133kPa),SaO2(90.0±4.6)%、(96.8±0.5)%及mPAP(31.2±5.5)、(16.6±1.8)mmHg,均有显著改善(P均<0.05);3例患者IC[(1.16±0.26)、(1.83±0.35)L]、TGV[(6.52±0.27)、(4.52±0.29)L]、RV[(5.12±0.39)、(3.20±0.32)L]、RV/TLC[(71.0±5.6)、(51.3±2.5)%]及Rawtotal[(6.62±0.99)、(2.48±0.87)cmH2O·L-1·s-1]改善显著(P均<0.05);4例患者PEF[(1.65±0.40)、(3.92±1.63)L/s]、DLCO[(8.5±3.0)、(21.0±6.2)ml·min-1·mmHg-1]及6MWD[(46.8±14.7)、(246.8±51.9)m]也显著增加(P均<0.05);FVC[(1.85±0.40)、(2.45±0.49)L]、TLC[(7.19±0.15)、(6.26±0.73)L]、DLCO/V·A[(2.90±1.50)、(5.41±0.87)L·min-1·mmHg-1]、P(Aa)O2[(37.6±16.3)、(17.8±6.3)mmHg]及PaCO2[(44.6±7.7)、(37.4±3.4)mmHg]有所改善,但差异无统计学意义(P均>0.05)。结论COPD患者肺移植术后肺通气、气道阻力、残气、弥散、运动耐力及气体交换功能均明显改善。 Objective To investigate the therapeutic effect of lung transplantation on pathophysiology and pulmonary function in chronic obstructive pulmonary disease (COPD) patients. Methods Five male COPD( grade IV ) patients, aged 51 to 63 yr, were enrolled in the study. The patients underwent pulmonary function tests and the following measurements 2 weeks before and 2 months after the operation. The measured parameters included forced vital capacity (FVC), forced expiratory volume in one second ( FEV1 ) , FEV1/FVC, maximal ventilatory volume ( MVV ), residual volume ( RV ), total lung capacity ( TLC ), RV/TLC, inspiratory capacity ( IC ), thoracic gas volume ( TGV ), peak expiratory flow ( PEF ) , total airway resistance(Raw total), diffusion capacity for CO of lung( DL CO), diffusion capacity for CO of lung/ alveolar volume( DLCO/VA ),6 minute walk distance (6MWD), partial pressure of oxygen in arterial blood (PaO2 ) , alveolar-artery oxygen gradient [ P(A-a) O2 ] , oxygen saturation in arterial blood ( SaO2 ) , partial pressure of carbon dioxide in arterial blood( PaCO2 ) and mean pulmonary arterial pressure(mPAP). Results The measured parameters before vs after the operation were as follows : MVV ( 23.6 ± 5.8 ) vs ( 71.6 ± 21.8)L,FEV1(0.68±0.21) vs (1.85±0.46)L,FEV1/FVC (37.4±8.3)% vs (75.6 ±13.9)%,PAO2 (60.0±9. 1) vs (86.2±2.9)mm Hg(1 mm Hg=0. 133 kPa),SAO2(90.0±4.6)% vs (96.8±0.5)% and mPAP (31.2±5.5 ) vs ( 16. 6±1.8 ) mm Hg; all were significantly improved in the 5 cases( all P 〈 0.05) ;IC[(1.16 ±0.26) vs (1.83 ±0. 35)L] ,TGV[ (6.52 ±0.27) vs (4. 52 ±0.29)L] ,RV[(5. 12 ± 0.39) vs (3.20±0.32)L] ,RV/TLC[ (71.0±5.6)% vs (51.3±2.5)%] and Raw total[ (6.62 ±0.99) vs (2. 48 ±0. 87)cm H2O · L^-1 · s^-1 ] were significantly improved in 3 of the 5 patients( all P 〈0. 05 ) ; PEF[ (1. 65 ± 0. 40 ) vs (3.92 ± 1.63) L/s],DLCO[(8.5 ±3.0) vs (21.0 ±6.2) ml · min^-1 mm Hg^-1] and 6MWD[ (46. 8 ± 14. 7 ) vs ( 246. 8 ± 51.9) m ] were significantly increased in 4 of the 5 patients(all P〈0. 05). FVC[(1.85±0.40) vs (2.45±0.49)L],TLC[(7.19±0.15) vs (6.26± 0.73)L] ,DLEO/VA[ (2.90± 1.50) VS (5.41 ±0. 87) L·min^-1. min^-1·mmHg^-1 ,P(A-a)O2[ (37.6 ±16.3) vs ( 17.8 ±6. 3)mm Hg] and PaCO2[ (44. 6 ±7.7) vs (37.4 ±3. 4)mm Hg] were also improved but did not reach significance ( all P 〉 O. 05 ) . Conclusion Spirometry, airway resistance, residual capacity, diffusion capacity, exercise tolerance and gas exchange were improved remarkably after lung transplantation in COPD patients.
