ABSTRACT
Objective:To investigate the diagnosis and treatment significance of invasive and noninvasive operation for ventilator?as?sociated pneumonia ( VAP ) . Methods:A total of 80 cases of VAP suspected patients who had received mechanical ventilation at least 48 hours in ICU from Jun 2014 to Mar 2015 were enrolled. Patients were randomly divided into four groups including noninvasive operation group ( F) , invasive operation group ( Q) , mix group 1 ( H1) and mix group 2 ( H2) . VAP diagnosis rate between groups as well as living time, antibiotic use time, survival rate, calcitonin levels and APACHE II score, oxygenation index were analyzed. Results:Specimen from invasive operation had higher specimens to cultivate positive rate than that from noninvasive operation ( P<0?05), but there was no statistic significant difference in VAP diagnosis rate between two methods (P>0?05). Conclusion:Noninva?sive operation collecting samples for VAP diagnosis is also accurate as invasive one. Collecting specimens from sputum suction tube in the clinical treatment on airway suction is a low cost and simple noninvasive operation.
ABSTRACT
Objective To evaluate the clinical effect in prevention of intravenous catheter-related infection(CRI) using antiseptic impregnated central venous catheter.Methods Intravenous catheter-related infection was retrospectively analyzed between 440 cases performed with general centrol venous catheter and 420 cases performed with antiseptic impregnated central venous catheter in ICU.Results There were 34 cases of CRI in 860 cases,28 cases were inserted general central venous catheter and 6 cases inserted antiseptic impregnated central venous catheter,the group of antiseptic impregnated was lower singificantly than the group of general in infection rate(P=0.0002).Conclusion Using antiseptic impregnated central venous catheter can reduce CRI,which has clinical effect in prevention of CRI.
