目的:分析ICU重症老年患者的呼吸机相关性肺炎病原的耐药性以及预防措施。方法:选取2014年6月至2015年5月我院收治的122例ICU重症老年呼吸机相关性肺炎患者作为研究对象,对患者气道分泌物进行病原的耐药性分析,从而采取针对性的措施进行预防,以免对患者造成不利的影响。结果:本文研究当中,122例患者共培养出260株气道分泌物病原菌,其中占比例最多的病原菌为革兰阴性菌,达到了57.7%(160/260),与其它类型的病原菌相比在数量上存在显著的差异P<0.05,有统计学意义。结论:ICU重症老年患者的呼吸机相关性肺炎病原主要以革兰阴性菌为主,并且对于各种抗生素都具有较强的耐药性。因此。在预防和治疗患者出现的呼吸机肺炎时不能乱用抗生素,需要提高抗生素使用的科学性,选择病原菌比较敏感的抗生素,这样才能预防和减少患者的呼吸机肺炎感染率。
Objective: To analyze the drug resistance of pathogens of ventilator-associated pneumonia and its preventive measures in critically ill elderly patients with ICU. Methods: From June 2014 to May 2015, 122 ICU patients with severe acute respiratory ventilator-associated pneumonia admitted to our hospital were selected as the research objects, and the pathogenic drug resistance of the airway secretions of the patients was analyzed, so as to take targeted Measures to prevent, in order to avoid adverse effects on patients. Results: Of the 122 patients studied in this study, 260 strains of airway secretions were co-cultivated. The most common pathogen was Gram-negative bacteria, accounting for 57.7% (160/260) of the total, with a significant difference from other types of pathogens The number of significant differences P <0.05, with statistical significance. Conclusion: The pathogens of ventilator-associated pneumonia in severe elderly patients in ICU are mainly Gram-negative bacteria, and are highly resistant to various antibiotics. therefore. In the prevention and treatment of patients with ventilator pneumonia can not indiscriminate use of antibiotics, the need to improve the scientific use of antibiotics, select the more sensitive pathogens antibiotics, so as to prevent and reduce the patient’s respiratory rate of pneumonia.
