Pathogenic bacteria analysis and countermeasures for nosocomial infection in neonatal wards

Abstract

Objective To analyze the nosocomial infection characteristics,pathogenic bacteria and relative risk factors,in order to provide the basis for preventing and controlling nosocomial infection,and to reduce the incidence of nosocomial infection in neonatal wards.Methods The study enrolled 603 neonatal patients hospitalized between July 2009 to July 2011.Results There were 58 nosocomial infection cases found in 603 neonatal patients, and the infection rate was 9.62 ％.The most common infections were respiratory tract infection,oral infections and gastrointestinal tract infection,with proportion rate of 53.45％,31.03％ and 15.52％ respectively.The main pathogenic bacteria was Klebsiella pneumoniae,accounting for 36％.Conclusions The lower gestational age and birth weight,bigger length of hospital stay and invasive operation are risk factors of nosocomial infection.We can reduce nosocomial infections through strengthening education,enhancing respiratory tract management,primary care,reasonable use of antibiotics,emphasizing washing hands,and strengthening comprehensive disinfection measures,.
