神经外科气管切开术后下呼吸道感染危险因素的调查分析

Risk Factors of Lower Respiratory Tract Infection in Neurosurgery Ward Patients with Tracheotomy:A Survey

目的了解神经外科气管切开术后下呼吸道感染特点和危险因素。方法调查神经外科60例气管切开术后下呼吸道感染情况,并对其相关危险因素进行分析。结果医院感染例次发生率93.3%,以下呼吸道感染占首位(例次感染率82.1%),病原菌以革兰阴性菌为主,本组患者均有严重的基础疾病,治疗中行气管插管、气管切开、吸氧、吸痰、雾化等治疗,气管切开置管时间、住院天数越长,下呼吸道感染率越高。结论气管插管、气管切开、气管切开置管时间、住院天数越长是下呼吸道感染发生的危险因素。

OBJECTIVE To tracheotomy. METHODS comprehend characteristics Lower respiratory tract and risk factors of lower infection condition of 60 respiratory tract infection after cases with tracheotomy was investigated. Risk factors were analyzed. RESULTS The prevalence of nosocomial infection was 93.3%, mainly lower respiratory tract infection （82.1%）. The most common pathogens were Gram-negative bacilli. This group of patients had the seriously underlying diseases. In the treatment they carried on the trachea intubation, the tracheotomy, oxygen inhalation, sputum aspiration, atomization and so on. The time the tracheotomy and days in hospital be longer, the lower respiratory tract infection be higher. CONCLUSIONS The trachea intubation, the tracheotomy, the time of tracheotomy and the longer days in hospital may be the risk factors which can cause the lower respiratory tract infection.
