探讨引起肝脏移植后肺部感染的常见因素及其防治策略，为肝移植后肺部感染治疗的进一步研究提供临床参考意见。

采用回顾性分析方法，分析我院2000年1月至2009年12月67例肝移植受者肺部感染的发生率、病死率、易感因素及防治措施等。

67例肝移植受者9例发生肺部感染，感染率13.4%，1例死亡，病死率11.1%，移植前后有多种因素与术后肺部感染有关。

肝移植术后肺部感染率、病死率较高，合理预防、早期诊断和及时处理，对于提高肝移植效果至关重要。肝移植临床医生应根据本地区、本单位致病微生物流行病学特点及实际医疗条件结合每个患者的具体情况，及时修正诊断与治疗，制定合理的预防与治疗方案。

To analyze the common causes of pulmonary infection after liver transplantation and improve treatment strategy, to provide the clinical advices for further research on treating the pulmonary infection after liver transplantation.

The clinical data of 67 patients undergoing liver transplantation in our hospital from Jan. 2000 to Dec. 2009 were studied retrospectively in order to analyze severe pulmonary infection incidence, fatality rate and susceptible factors as well as treatment strategy.

There were 9 of 67 patients who caught pulmonary infection and the incidence was 13.4%. The mortality rate in the patients who developed pulmonary infection was 11.1%. Pulmonary infection can be caused by the factors before or after operation.

The incidence and mortality of pulmonary infection after liver transplantation are high. The key factors to improve the effects of liver transplantation are reasonably prevented pulmonary infection, timely treat and diagnose early after surgery. The clinical doctor should modify diagnosis and treatment for patients according to characteristics of pathogenic microorganism epidemiology in local area combine with individuals,more importantly, constitute schemes of prevention and treatment reasonably based on practice medicine conditions.
