老年呼吸重症患者医院内感染临床分析

Clinical analysis of nosocomial infection in elderly patients with severe respiratory

目的 探讨老年呼吸重症患者医院内感染情况.方法 对在院发生住院感染的48 例老年呼吸种重症患者的临床资料进行回顾分析,对院内感染患者病原菌种类以及分布情况做探讨.结果 患者经药敏试验和细菌培养后,共分离出病原菌108 株,其中,革兰阴性菌68 株,占比63. 0%,革兰阳性菌28 株,占比25. 9%,真菌12 株,占比11. 1%.病原菌分布中,分布在呼吸道71 株,占比65.7%;大静脉置管9 株,占比8.3%;泌尿道14 株,占比13.0%;消化道7 株,占比6.5%;皮肤切口3 株,占比2.8%;引流管4 株,占比3. 7%.结论 老年呼吸重症患者院内感染的主要因素是感染病原体,患者选用合适的抗生素药物有助于感染康复.

Objective To i nvestigate t he i nfection of n osocomial i nfection i n e lderly p atients w ith s evere r espiratory.Methods A total of 48 elderly patients with severe respiratory syndrome were retrospectively analyzed. The types anddistribution of pathogens in nosocomial infection were investigated. Results After the d rug susceptibility test a nd bacterialculture, 108 strains of pathogenic bacteria were isolated. Gram-negative bacteria were 68 strains, accounting for 63.0%.Gram-positive bacteria were 28 strains, accounting for 25.9%. Fungi were 12 strains, accounting for 11.1%. The distributionof pathogens were as followed： 71 strains in the respiratory tract, accounting for 65.7%; 9 strains in large venous catheter,accounting for 8.3%; 14 strains in urinary tract, accounting for 10.3%; 7 strains in digestive tract, accounting for 6.5%; 3strains in skin incision, accounting for 2.8%; 4 strains in drainage tube, accounting for 3.7%. Conclusion The main factor innosocomial infection in elderly patients with severe respiratory illness is infection pathogens. The appropriate antibiotic drugsin patients is conducive to infection and rehabilitation.
