食管肿瘤患者气管插管全麻术后肺部感染的临床分析

目的探讨食管肿瘤患者气管插管全麻术后肺部感染的病原菌、危险因素和耐药性。方法选取2011年1月至2013年4月间收治的48例食管肿瘤气管插管全麻术后肺部感染患者作为观察组,选取同期45例食管肿瘤气管插管全麻术后无肺部感染者为对照组,分析病原菌、危险因素和耐药性情况。结果食管肿瘤气管插管全麻术后肺部感染以革兰氏阴性菌为主,对亚胺培南、泛生舒复耐药性低,其与基础疾病、气管插管置留时间、住院时间、术后镇痛、无菌操作、术后抗生素应用和术后激素应用有关(P<0.05)。结论食管肿瘤患者气管插管全麻术后肺部感染的影响因素众多,在临床上要规范操作气管插管且对症处理。

Clinical analysis of pulmonary infection in esophageal tumor patients after general anesthesia with endotracheal intubation

Objective To investigate postoperative pulmonary infection pathogens, risk factors and drug resistance after general anesthesia of esophageal cancer. Methods 48 cases with esophageal cancer endotracheal intubation pulmonary infection hospitalized from January 2011 to April 2013 were selected as the observation group, and at the same period 45 cases without esophageal cancer after general anesthesia en- dotracheal intubation lung infection as the control group. Pathogens, risk factors and drug resistance were ob- served. Results The majority of the pathogenic bacteria of esophageal cancer tracheal intubation pulmonary infection were Gram- negative bacteria, and the resistance to imipenem, ceftriaxone sodium for injection re- sistance remained low. the risk factors included underlying diseases, endotracheal intuhation home leave, hos- pitalization time, postoperative analgesia, aseptic operation, postoperative antibiotics, postoperative hormone application and so on （ P 〈 0. 05 ）. Conclusion There are many factors affecting esophageal cancer tra- cheal intubation pulmonary infection. The operation of the clinical tracheal intubation should be regulated and symptomatic treatment be adopted.
