醫(yī)學論文范文:肝移植患者術(shù)后細菌感染的臨床分析

【摘要】 目的 探討肝移植患者術(shù)后細菌感染的發(fā)生情況及相關因素。方法 回顧性分析我院2005年1月～2007年10月期間的肝移植術(shù)后患者56例次的臨床資料，討論細菌感染的發(fā)生情況，并對可能導致術(shù)后細菌感染的相關因素進行分析，篩選臨床危險因素。結(jié)果 本組56例患者中29例(51.8%)發(fā)生細菌感染，感染部位以肺部(53.7%)為主，感染的菌種中G+菌(46.3%)主要為金葡菌及腸球菌，G-菌(53.7%)分布較分散。單因素及多因素logistic回歸顯示手術(shù)時間超過10h及呼吸機使用時間超過24h為手術(shù)后細菌感染的危險因素。結(jié)論 細菌感染是肝移植術(shù)后常見的并發(fā)癥，臨床應針對其可能的危險因素，采取提高手術(shù)技巧，促進呼吸功能恢復等手段，以減少術(shù)后細菌感染的發(fā)生。

ABSTRACT: Objective To explore the incidence and risk factors of bacterial infection after othtotopic liver transplantation (OLT). Methods Altogether 56 OLT recipients from January 2005 to October 2007 were included in the study. The incidents and the related variables of the infection were analyzed retrospectively. The related variables were evaluated using multivariate logistic regression model to identify the significant risk factors. Results Bacterial infection was confirmed in 29 recipients (51.8%). Among them, the lung infection was the most common site (53.7%). The Gram�瞤ositive cocci were 46.3%, while the Gram�瞡egative bacilli were 53.7%. The risk factors for bacterial infection included duration of the operation and detained respirator using. Conclusion Bacterial infection is a major complication following OLT. Surveillance for the risk factors, enhancement the skill of operation, and improving the recovery of respiratory function is the key to decreasing the incidence of bacterial infection after transplantation.

肝移植手術(shù)已經(jīng)在治療終末期肝病方面取得了很大成功。但是，術(shù)后感染是肝移植術(shù)后常見的并發(fā)癥，往往影響手術(shù)的預后，其發(fā)生率高達37.9%～66%[1��2]，其中細菌感染約占所有病原體感染的2/3[2��3]。了解肝移植術(shù)后細菌感染的種類及分布特點，對于肝移植術(shù)后感染的預防和護理有重要作用。現(xiàn)將我院肝移植科2005年1月～2007年10月施行的56例肝移植患者術(shù)后院內(nèi)細菌感染情況和分離的所有菌株進行回顧性分析，以初步探討術(shù)后細菌感染的相關危險因素。
