[The monitoring and analysis of arthroplasty related infection].
OBJECTIVE
To monitor and analyze the arthroplasty related infection situations of Drum Tower Hospital, so as to provide evidences for the prevention of infection after arthroplasty.


METHODS
Monitoring of infection situations of nine arthroplasty operations were carried out from July to August in 2008. Five sampling methods were used to monitor the air of the 30 m2 surgery for 4 times. Through the cotton swab sampling, hands of 14 surgeons and 76 samples of surgical instruments (forceps, surgical scissors, retractors) were collected and then for bacterial culture.


RESULTS
The average amount of the total number of free-floating bacteria in our surgery was 88.2 cfu/m3. For the germiculture, 8 samples of hand detections were positive; 11 samples of surgical instruments including those used and unused and exposed at different times were positive.


CONCLUSIONS
In the surgery of arthroplasty, all operation personnels should protect the air cleanliness degree, obey the surgical hand-washing rules and diminish the exposed time of aseptic table.
