Abstract:
OBJECTIVE To have an retrospective analysis of the prevalent fungi infected in patients in ICU,and their pathologic sites and drug resistance and to find out the hazard factors.METHODS The research used API 20C AUX and Rosco disk diffusion method to test the drug resistance of fungi isolated from the infected samples collected from ICU patients in our hospital between Jan 2006 and Mar 2007.RESULTS Totally 123 fungi strains were spotted,the majority of them being Candida albicans,accounting for 34.1%;Candida glabrata 26.8% and Candida tropicalis 18.7%.All the fungi were sensitive to amphotericin B and nystatin(Mycostatin) and partially resistant to fluconazole,itraconazole and ketoconazole.Patients with long term use of wide-spectrum antibiotics and catheters and elder patients would have higher fungi infection rate.CONCLUSIONS Candida are the major pathogens of fungal infections in ICU.The major infected site is lower respiratory tract.Amphotericin B and nystatin have good sensitivity but higher toxicity.Conazole medicines also have good sensitivity to C.albicans and C.tropicalis.But they are resisted largely by C.glabrata and C.krusei.Reasonable use of bacteriophage and reduction of unnecessary diagnosis and treatment procedures,and early discovery,diagnosis and treatment are keys to prevent and cure the invasive fungal infections.
