Abstract:
OBJECTIVE To discuss the constitution and drug sensitivity of pathogens that cause pulmonary infection in NICU. METHODS Sputa were collected from patients hospitalized in NICU from Mar 2006 to Mar 2007 and analyzed for distribution and drug sensitivity of pathogenic bacteria. RESULTS All 555 strains of pathogenic bacteria were isolated. The most common pathogens were Pseudomonas aeruginosa(183 strains,33.0%),Staphylococcus aureus(114 strains,20.5%) and Klebsiella pneumoniae(56 strains,10.1%). Nearly most pathogenic bacteria were multi-resistant to commonly used antibiotics. Meticillin resistant strains of S. aureus accounted for 97.4%. The percentange of fungi strains was increasing in NICU. The main isolated strains were Candida tropicalis(5.9%),C. albicans(3.8%)and C. glabrata(3.6%). And all of the fungi were sensitive to amphotericin B. fluconazole. and ketoconazole. CONCLUSIONS Pulmonary infections in NICU are mainly caused by Gram-negative bacteria with high rate of drug resistance. It can be of great importance to make drug sensitivity tests at regular intervals to guide the use of antibiotics.
