Abstract:
Objective To investigate the institution of extracorporeal membrane oxygenation(ECMO) for primary graft dysfunction( PGD) after lung transplantation and analysis its clinical outcome. Methods From September 2002 to December 2013, 286 patients with end-stage lung disease underwent lung transplantation(LTx) in Wuxi People's Hospital. Among them, there were 22 patients occured grade 3 PGD in early stage after LTx. In which there were 2 cases with chronic obstructive pulmonary disease, 12 with idiopathic pulmonary fibrosis, 4 case with primary pulmonary hypertension, 1 case with lung tuber-culosis, 1 case with silicosis, 2 cases with bronchiectasis. There were 7 patients with single LTx(3 cases with ECMO support) and 15 patients with bilateral LTx(2 cases with CPB support and 6 cases with ECMO support). According to the severity levels of PGD, different treatment measures were used, such as reinforce ventilatory support, negative fluid balance, extending the treatment time of the ventilator, the use of pulmonary vasodilators, such as prostaglandin E1 and ECMO. Results Six patients were treated by adjusting low volume, high frequency and high positive end expiratory pressure ventilation( PEEP) mode, and 2 cases reversed, 4 cases died of respiratory failure. 16 cases accepted ECMO support, among them 10 cases apply venous-ve-nous mode, 6 cases venous-artery mode, the average flow time was 5. 5 days. 10 cases dismantled from ECMO successly and 6 cases died of multiple organ failure, infection and cardiac arrest. 30-day, 1-year and 5-year survival of PGD recipients post-op-eratively were 55％, 40％, 25％, respectively. Conclusion The high incidence of PGD causes high mortality peri-operative-ly after LTx. Preventing PGD can improve the survival rate of the lung transplant patients. Once PGD happens, appropriate treatment should be given as soon as possible. ECMO can effectively promote the transplanted lung function recovery, reduce the perioperative mortality. If the indications of ECMO use was reached, the institution of ECMO should as soon as possible.
