Abstract:
Objective To understand and analysis of the pathogens distribution and drug resistance of nosocomial infection in children′s hospital,so as to provide reliable scientific basis for the prevention and control of hospital infection.Methods 396 cases of upper respiratory tract specimens were collected from pediatric patients with nosocomial infection.These specimens were detected by sputum specimens conventional methods of microorganism cultivation,and K-B method was used to determine the bacteria sensi-tivities to clinical common drug.Results There were 225 cases of specimens were pathogen positive among all the 396 specimens, and 234 strains of bacteria were isolated in all.The positive isolated rate was 56.8%(225/396).Among the 234 isolated strains, Gram negative bacteria accounted for 72.6%(170/234),and Klebsiella occupied the first place[49.4%(84/170)].Gram positive bacteria accounted for 23.5%(55/234),and Staphylococcus had the highest isolated rate in Gram positive bacteria[58.2% (32/55)].In all the 9 kinds of clinical common antimicrobial agents,imipenem had high drug sensitivity to the 234 isolated strains,and the aminoglycosides came next.Conclusion It is necessary for the pediatric patients with nosocomial infection to collect upper re-spiratory tract specimens for bacteriologic studies and drug sensitivity tests.
