Abstract:
OBJECTIVE To analyze the high risk factors and etiology character of ventilator-associated pneumonia(VAP) and provide the guidance for preventing VAP. METHODS Eighty three cases given mechanic ventilation over 48 hours in ICU of our hospital from Jan to Oct 2005 were observed.Thirty seven cases met the diagnosis criteria of VAP,while 46 cases without VAP were taken as control. RESULTS Airway secretion was cultivated and Gram-negative germ was the majority(58.0%).The first three pathogens were Pseudomonas aeruginosa(32.0%),Acinetobacter,and Staphylococcus epidermidis,22.0% cases had mixed infection with fungi.Except antiacid treatment,the following factors,such as long time for mechanical ventilation,trachea incision,corticosteroids treatment and coma state had significant relationship with the occurrence of VAP. CONCLUSIONS The occurrence of VAP is related with multiple clinical factors.Clinicians should reduce high risk factors to lower the occurrence of VAP.
