OBJECTIVE To observe the interior contamination of reserve suction bottles used as the terminal apparatus of medical suction center and identify the prevailing bacteria related to the contamination. METHODS A total of 65 samples were collected from the interior of suction bottles of critical care units and operation rooms in our hospital and cultured with routine method. The bacteria identification was done after 24 hours cultivation at 37℃. RESULTS From them 42 samples were contaminated. The results indicated that the contamination rate of the interior of reserve suction bottle might be as high as 64.6%. The prevailing bacteria of the contamination were Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. CONCLUSIONS The interior contamination of the reserve suction bottle might be the potential source of nosocomial infection. It is important and necessary to clean and sterilize the interior of the reserve suction bottle regularly.
