The aim of this study is to assess wether the use of the bacteriological filter Pall BB 22 15 placed on the Y piece of the anesthesia equipment decreases contamination and furthermore to evaluate the cost of this practice versus changing anesthetic circuits after every patient. Randomized trials are conducted with three "Engström" machines in three cardiac surgery operating rooms. The Y pieces were examined with qualitative and quantitative bacteriological analysis. Use filters is less expensive than changing circuit for each patient for a comparable efficacy.
