医院获得性下呼吸道感染在医院感染中居首位,死亡率高达40%,是住院者死亡的主要原因之一。引起医院获得性下呼吸道感染的病原菌很多,革兰氏阴性杆菌是主要的致病菌,而金黄色葡萄球菌,尤其是耐甲氧西林金黄色葡萄球菌(MRSA)和其他阳性球菌如肺炎链球菌也逐渐成为重要的致病菌。为提高对医院获得性MBSA下呼吸道感染的认识,我们对近两年来我院发生的18例医院获得性感染病例进行分析,报告如下。
Hospital-acquired lower respiratory tract infections rank the highest among nosocomial infections with a mortality rate of 40%, which is one of the major causes of death in hospitalized patients. Many pathogenic bacteria cause hospital-acquired lower respiratory tract infections. Gram-negative bacilli are the major pathogenic bacteria, while Staphylococcus aureus, especially methicillin-resistant Staphylococcus aureus (MRSA) and other positive cocci such as Streptococcus pneumoniae It has also become an important pathogen. To raise awareness of hospital-acquired lower respiratory tract infections with MBSA, we analyzed 18 hospital-acquired infections that occurred in our hospital in the past two years and are reported below.
