气管切开患者医院感染危险因素研究

STUDY ON RISK FACTORS STUDY OF TRACHEOTOMY NOSOCOMIAL INFECTION

目的研究气管切开患者医院感染状况,分析危险因素。方法通过回顾性调查与病原学检测,对67例气管切开患者医院感染发生率及其危险因素进行研究。结果本医院在2010-2011年期间共有67例住院患者实施气管切开治疗,发生医院感染48例,医院感染率71.6%。感染部位主要为下呼吸道感染。有53例次感染患者送检病原学标本,检出病原菌37株,革兰阴性菌占86.5%,多数为耐药菌株。气管切开并留置插管是引发感染的主要因素,患者长期卧床、伴随心血管疾病、高龄等因素与感染密切相关。结论气管切开患者医院感染率高,影响因素多,下呼吸道感染后果严重,只有采取综合防控措施方可奏效。

Objective To study the nosocomial infection of tracheotomy in patients, and to analyze the risk factors. Methods Retrospective survey and pathogen detection were used to study the incidence rate od hospital disinfection and risk factors of the 67 tracheal incision patients. Results In the period of 2010 - 2011,67 cases of inpatients had tracheotomy, 48 cases had nosocomial infection, the infection rate was 71.6%. The main infection site was the lower respiratory tract. There are 53 cases of infected patients had etiology specimens detection, 37 of them found pathogens, Gram - negative bacteria accounted for 86. 5%, the majority were drug - resistant strains. Tracheostomy and indwelling catheter were the main risk factor of infection, the patient with bedridden, accompanied by cardiovascular disease, old age and other factors closely related to the nosocomial infection. Conclusion Tracheotomy was followed high rate of nosocomial infection in patients. Many factors affect the infection, lower respiratory tract infection was seriou. We should take a comprehensive prevention and control measures.
