ABSTRACT

OBJECTIVE To explore the reason, characteristic,prevention and treatment measures of acquired fungal infection in cardiosurgery intensive care unit(CSICU). METHODS A total of 153 patients who were admitted to our CSICU ward and had perfect microorganism materials from Jan 1999 to Jul 2002 were investigated with retrospective method,in which 34 cases were acquired fungal infection. RESULTS The rate of fungal infection was 21.52%.The most common infection site was lower respiratory tract.The patients after cardiac injury were easy to be infected.The Candida were the main pathogens,especially Candida tropicalis.The cardiopulmonary bypass(CPB) time,the time stayed in ICU,mechanical ventilation time, urinary dwelling tracheal intubation or tracheotomy,fiber bronchoscope and central venous intubation were the risk factors. CONCLUSIONS The reason of acquired fungal infection in CSICU is that CPB decreases patient′s immunity and every invasive exam or treatment can break the normal immunity.
