摘  要:目的观察间断肺动脉灌注静脉血对体外循环(CPB)肺损伤的保护作用。方法60例慢性阻塞性肺疾病(COPD)患者[第1秒钟用力呼吸容积(FEV1)/肺活量(FC)〈70%]接受心脏瓣膜置换术,随机分为肺灌注组和对照组(n=30),肺灌注组CPB开始后间断灌注静脉血。检测外周血不同时间点[CPB开始前(T1)、CPB结束时(T2)、CPB结束后3 h(T3)、CPB结束后24 h(T4)、术后48 h(T5)]中性粒细胞弹性蛋白酶(NE)、肿瘤坏死因子-α(TNF-α)和白细胞介素(IL)-10,测算插管后切皮前(T1a)、手术结束时(T2a)肺泡动脉血氧分压差(A-aDO2)和氧合指数(OI),PiCCO监测仪连续收集切皮后(T1b)和关胸前(T2b)血管外肺水(EVLW),记录术后呼吸机使用时间、ICU停留时间及术后30 d内死亡率等临床指标。结果CPB开后T2~T5各时间点NE、TNF-α和IL-10水平显著升高,灌注组NE低于对照组[(727.6±202.8)比(987.1±253.5) ng/ml,t=4.378,P=0.000;(460.4±162.4)比(579.5±215.5) ng/ml,t=2.418,P=0.019;(241.3±138.9)比(379.9±180.8) ng/ml;t=3.329,P=0.002;(151.3±48.1)比(284.1±125.2) ng/ml,t=5.423,P=0.000],TNF-α低于对照组[(43.1±17.8)比(58.8±20.2) pg/ml,t=3.194,P=0.002;(57.1±20.8)比(82.8±24.3) pg/ml,t=4.401,P=0.000;(42.3±19.7)比(63.3±26.5) pg/ml,t=3.,483,P=0.001;(31.2±15.3)比(50.5±22.3) pg/ml,t=3.908,P=0.000],而IL-10高于对照组[(109.7±29.8)比(88.4±26.3) pg/ml,t=2.935,P=0.005;(87.3±24.5)比(74.7±21.6) pg/ml,t=2.113,P=0.039;(66.5±17.2)比(54.3±14.2) pg/ml,t=2.996,P=0.004;(44.8±10.8)比(39.7±8.5) pg/ml,t=2.033,P=0.047];手术结束各时间点灌注组OI高于对照组,A-aDO2及EVLW低于对照组[317±147比246±116,P=0.042;166±76比217±110,P=0.041;(12.0±2.Objective To study the effects of pulmonary perfusion with venous blood on the inflammatory response and clinical outcome of patients with chronic obstructive pulmonary disease (COPD) after cardiac undergoing cardiopulmonary bypass. MethodsSixty COPD patients (forced expiratory volume in 1 s/vital capacity 〈70%) undergoing valve replacement were block-randomized to PP (venous blood, temperature 20℃, 3 L) or standard cardiopulmonary bypass (CPB, n=30). The plasma levels of interleukin (IL)-10, tumour necrosis factor-α (TNF-α) and neutrophil elastase (NE) in peripheral blood were determined at different time-points [T1: pre-CPB, T2: end of CPB, T3: 3 h, T4: 24 h, and T5: 48 h postoperatively]. Alveolar-arterial O2 tension difference (A-aDO2) and oxygenation index (OI) were measured before skin incision and after intubation (T1a) and end of surgery (T2a). Extravascular lung water (EVLW) was measured after skin incision (T1b) and before chest closure (T2b). The clinical outcome [mortality, morbidity, intubation time, intensive care unit (ICU) stay] was recorded at patient discharge and 30 days after surgery.ResultsCompared with the control group, the plasma levels of NE and TNF-α were significantly reduced as compared with those in the perfusion groop at T2-T5 [NE: (727.6±202.8) vs. (987.1±253.5) ng/ml, t=4.378, P=0.000; (460.4±162.4) vs. (579.5±215.5) ng/ml, t=2.418, P=0.019; (241.3±138.9) vs. (379.9±180.8) ng/ml, t=3.329, P=0.002; (151.3±48.1) vs. (284.1±125.2) ng/ml, t=5.423, P=0.000; TNF-α: (43.1±17.8) vs. (58.8±20.2) pg/ml, t=3.194, P=0.002; (57.1±20.8) vs. (82.8±24.3) pg/ml, t=4.401, P=0.000; (42.3±19.7) vs. (63.3±26.5) pg/ml, t=3.483, P=0.001; (31.2±15.3) vs. (50.5±22.3) pg/ml, t=3.908, P=0.000]. The plasma levels of IL-10 was significantly higher in the perfusion group than in the control group at T2-T5 [(109.7±29.8) vs. (88.4±26.3) pg/ml,
