外科危重病人呼吸道院内感染的调查分析

目的：了解外科危重病人呼吸道院内感染致病菌及其细菌耐药性情况．为临床防治提供依据。方法：对我院SICU1997年1月～1999年12月三年间从痰标本中所分离的致病菌及其细菌耐药性进行回顾性调查。结果：外科危重病人呼吸道内感染仍以G^-菌为主，占58．0％，其次真菌25．4％、G^ 菌16．6％，致病菌前四位分别铜绿假单胞菌、白色念珠菌、嗜麦芽窄食黄单胞菌和耐甲氧西林金黄色葡萄球菌。体外药物敏感试验显示主要的致病菌均呈多重耐药特性。结论：本SICU呼吸道院内感染的致病菌仍以G^-菌为主，致病菌呈多重耐药特性，掌握本科室呼吸道内感染致病菌谱及其耐药特性具有重要意义。

RESPIRATORY TRACT NOSOCOMIAL INFECTION IN SURGICAL CRITICAL PATIENTS

Objective:To get knowledge of the path og ens of nosocomial infection and their antibiotics resistance in surgical critica l patients.Methods:The pathogens isolated from surgical critical patients' sputum and their antibiotics resistance were retrospectively analysed from Janu ary 1997 to December 1999 in SICU.Results:The main pathogens of nosocomial infection from surgica l critical patients' respiratory tract were still Gram-negative bacteria(58 0% ) and then fungi(25 4%)and Gram-positive bacteria (16 6%) The most frequently reported microorganisms were Pseudomonas aeruginosa(PA),Candida albicans ,Stenotr ophomas maltophilia(SM) and meticillin resistant Staphylococcus aureus(MR SA).The drugs sensitivity test in vitro showed that the main pathogens were all in multy-drugs resistance.Conclusions:The Gram-negative bacteria was still the prevalenc e pathogens of respiratory tract nosocomial infection in surgical critical patien ts.The main pathogenic bacteria were multi-drugs resistant.So it was important to surveilley the change of pathogens and their drug sensitivity of respiratory tract nosocomial infection in your department.
