Suction tip contamination in the ultraclean-air operating theatre.

Abstract

The surgical suction tip forms a reservoir for microorganisms during total hip replacement in conventional operating theatres. We assessed the colonisation of the tip in an ultraclean-air operating theatre in 39 patients, and found that 41% of them had evidence of bacterial colonisation with one or more bacteria. To avoid contamination we suggest that the suction tip is changed before preparation of the femoral canal and insertion of cement and prosthesis.
