Abstract:
Objective The drug resistance and risk factors of methicillin resistant Staphylococcus aureus (MRSA) infected in the pediatric ward of the hospital were analyzed to provide a scientific basis for the con-trol of MRSA paediatric infection .Methods Totally 306 strains of Staphylococcus aureus were isolated from the pediatric wards in the Affiliated Hospital of Southwest Medical University from July 2015 to June 2016 , the bacterial species identification and drug susceptibility tests were performed by MicroScan WalkAway 96SI and the statistical analysis was carried out by WHONET 5 .4 softwate .The clinical data of 306 children were infected with staphylococcus aureus collected by retrospective survey ,the risk factors of MRSA infection were analyzed by the method of χ2 test and non-condition Logistic regression .Results A total of 90 strains of M R-SA were detected ,with a detection rate of 29 .41％ .MRSA was mainly isolated from sputum ,accounting for 74 .44％ ,followed by blood ,accounting for 10 .0％ .MRSA was mainly resistant to amikacin ,ampicillin ,eryth-romycin ,clindamycin and other antimicrobial agents (P< 0 .05) .Age< 1 years ,venous catheterization ,me-chanical ventilation ,tracheal intubation ,ventilator ,stay in ICU ,hospitalization time >7 d ,use of corticoste-roids ,low albumin ,and antibiotic use time >7 d were the main risk factors of MRSA in children (P<0 .05) . Admission to NICU ,venous catheterization ,mechanical ventilation and tracheal intubation were independent risk factors .Conclusion MRSA isolated from pediatric wards is resistant to many kinds of antibiotics .Infec-tion with MRSA is related to many factors .Hospitals should take corresponding measures to reduce the inci-dence of M RSA infection .
