医院内下呼吸道感染占全部获得性感染的10％～20％,次于尿路感染及外科伤口感染而居第3位,尽管应用有效的抗生素但死亡率却是所有获得性感染中最高者。达200％～50％。而且细菌的耐药菌株多,治疗困堆,因而早期发现并及时防治获得性下呼吸道感染十分重要。为此,我们分析了本院48例院内下呼吸道感染,了解其临床病原学特点及影响预后的因素,以便指导有效的抗生素治疗,控制各种不利的因素,提高对医院内感染的认识。
Nosocomial lower respiratory tract infections account for 10% to 20% of all acquired infections, second only to urinary tract infections and surgical wound infections, and mortality is the highest among all acquired infections, despite the availability of effective antibiotics. Up to 200% ~ 50%. And bacterial resistant strains and more, the treatment of sleepy heap, and thus early detection and timely prevention and control of acquired lower respiratory tract infection is very important. Therefore, we analyzed 48 cases of nosocomial lower respiratory tract infection in our hospital to understand their clinical etiological characteristics and prognostic factors in order to guide effective antibiotic treatment, control various adverse factors, and raise awareness of nosocomial infections.
