目的 探讨肺移植术后原发性移植物功能丧失(PGD)的预防和治疗.方法 回顾性分析2002年9月至2011年6月间108例肺移植的临床资料.术后监测所有受者的血液气体分析及胸部X线表现,连续监测有创动脉压、肺动脉压和(或)中心静脉压.术后3d保持受者液体负平衡,根据动脉血氧分压(PaO2)和(或)血氧饱和度控制吸入氧浓度(FiO2),根据血液气体分析结果及生命体征调节呼吸机通气参数,以预防PGD的发生.术后早期一旦出现PaO2、FiO2急剧下降(低于200),且胸部X线片显示移植肺中下肺野密度增高,在排除超急性排斥反应、静脉吻合口梗阻、心源性肺水肿及肺部感染后,根据国际心肺移植协会制定的标准将PGD分级为3级的患者明确诊断为PGD.对于PGD级别的不同,分别给予受者加强通气支持、液体负平衡、延长呼吸机治疗时间、使用肺血管扩张药如前列地尔及使用ECMO等治疗措施.结果 术后共有10例受者发生PGD,发生率为9.3%(10/108).10例患者中,6例常规使用呼吸机支持治疗,持续时间为(285.8±238.6)h,其中2例逆转,4例死于PGD后呼吸衰竭;4例使用了体外膜肺氧合(ECMO)辅助治疗,其中2例在发生PGD后24 h内应用了ECMO,成功逆转后长期存活,另2例由于应用时间较晚(24 h后),病情恶化,分别在应用ECMO后第8和第11天死于PGD导致的急性肾功能衰竭和多器官功能衰竭.结论 肺移植后PGD的发生率高,应在围手术期加强管理,进行积极预防;一旦受者发生PGD,应尽快给予相应治疗,如达到使用EC MO的指征,应尽早使用.
目的 探討肺移植術後原髮性移植物功能喪失(PGD)的預防和治療.方法 迴顧性分析2002年9月至2011年6月間108例肺移植的臨床資料.術後鑑測所有受者的血液氣體分析及胸部X線錶現,連續鑑測有創動脈壓、肺動脈壓和(或)中心靜脈壓.術後3d保持受者液體負平衡,根據動脈血氧分壓(PaO2)和(或)血氧飽和度控製吸入氧濃度(FiO2),根據血液氣體分析結果及生命體徵調節呼吸機通氣參數,以預防PGD的髮生.術後早期一旦齣現PaO2、FiO2急劇下降(低于200),且胸部X線片顯示移植肺中下肺野密度增高,在排除超急性排斥反應、靜脈吻閤口梗阻、心源性肺水腫及肺部感染後,根據國際心肺移植協會製定的標準將PGD分級為3級的患者明確診斷為PGD.對于PGD級彆的不同,分彆給予受者加彊通氣支持、液體負平衡、延長呼吸機治療時間、使用肺血管擴張藥如前列地爾及使用ECMO等治療措施.結果 術後共有10例受者髮生PGD,髮生率為9.3%(10/108).10例患者中,6例常規使用呼吸機支持治療,持續時間為(285.8±238.6)h,其中2例逆轉,4例死于PGD後呼吸衰竭;4例使用瞭體外膜肺氧閤(ECMO)輔助治療,其中2例在髮生PGD後24 h內應用瞭ECMO,成功逆轉後長期存活,另2例由于應用時間較晚(24 h後),病情噁化,分彆在應用ECMO後第8和第11天死于PGD導緻的急性腎功能衰竭和多器官功能衰竭.結論 肺移植後PGD的髮生率高,應在圍手術期加彊管理,進行積極預防;一旦受者髮生PGD,應儘快給予相應治療,如達到使用EC MO的指徵,應儘早使用.

Objective To evaluate the prevention and treatment of primary graft dysfunction (PGD) after lung transplantation (LTx).Methods We retrospectively analyzed clinical data of108 cases of lung transplantation from September 2002 to June 2011. All the recipients were given continuous monitoring of invasive arterial pressure,pulmonary artery pressure and (or) central venous pressure and artery blood gas analysis and chest X-ray examination postoperatively.The negative fluid balance of the recipients in the first 3 days was maintained.The inspired oxygen (FiO2) or ventilator parameters was adjusted according to the arterial oxygen tension (PaO2) and (or) oxygen saturation,to prevent the occurrence of PGD.Once PaO2/FiO2 sharp decline (less than 200),and chest X-ray showed higher density of the lower transplanted lung fields in the early postoperative period,PGD could be diagnosed when acute rejection,venous anastomotic obstruction,cardiogenic pulmonary edema and pulmonary infections were excluded.According to the standards set by the International Association of Heart and Lung Transplantation,PGD is divided as 0,1,2 and 3.Different levels of PGD were treated by ventilatory support,negative fluid balance,extending the treatment time of the ventilator,the use of pulmonary vasodilators,such as prostaglandin E1and the use of ECMO.Results PGD occurred in10 cases,and the incidence rate was 9.3%. 6 cases were given conventional ventilatory support for (285.8 + 238.6) h (Two cases obtained reversal of PGD,and four cases died) ; the rest four cases were given ECMO (Two cases were supported by ECMO in 24 h after the occurrence of PGD and had a long-term survival after a successful reversal of PGD,and the rest two cases died from acute renal failure and multiple organ failure induced by PGD on the 8th and11th day of the application of ECMO due to the late application of ECMO (after 24 h).Conclusion The high incidence of PGD causes high mortality perioperatively after lung transplantation.Preventing PGD can improve the survival rate of the lung transplant patients.Once PGD happens,appropriate treatment should be given as soon as possible.
