Pseudomonas infection and the anaesthetist.

Cultures of specimens taken from anaesthetic equipment after routine cleaning and chemical decontamination revealed contamination with Pseudomonas Aeruginosa. Attention is drawn to the widely practised but unsatisfactory methods of decontaminating equipment. Consideration of the subject of decontamination of anaesthetic equipment led to the re-evaluation of our current practice, with surprising results. At the end of our brief look, we had changed our methods of decontamination dramatically and heightened awareness of a large section of theatre staff with regard to aseptic technique. We had also found a possible method of eliminating Pseudomonas Aeruginosa from the sinks in the operating theatre. Recommendations as to future practice are included.
