Abstract:
Objective To investigate colonization of multidrug-resistant organisms (MDROs)in neonatal intensive care unit (NICU)newborns on admission.Methods From April to November 2013,293 newborns who admitted to NICU of a hospital were screened for methicillin-resistant Staphylococcus aureus (MRSA)by nasal and throat swabs and for extended-spectrumβ-lactamases (ESBLs)bacteria and vancomycin-resistant Enterococcus (VRE)by anal swabs.Results Of 293 newborns,61 were detected MDROs (20.82%).The positive rate of MDROs screening in newborns aged <3 days(5.92%)was lower than those aged <3-6 days(37.74%)and 7-28 days (43.66%), the difference was significant (P =0.000).The major colonized MDROs were ESBLs-producing bacteria(83.60%), the major colonized site was anus(88.52%).Conclusion Neonatal anus and stool are important sources of MDROs in NICU;more attention should be paid to colonization screening for MDROs by anal swabs in newborns aged >3 days,and appropriate isolation measures should be taken for positive screening patients to prevent the transmission of MDROs.
