Bacterial contamination of PCA and epidural infusion devices.
We prospectively audited the bacterial contamination of re-usable analgesia infusion pumps. In a one-month period, 112 samples from the handset and keypads of our analgesia infusion pumps were cultured for bacterial contamination. Forty-five percent of handset swabs and 46% of keypad swabs grew bacteria; the commonest organism being coagulase-negative staphylococcus. An additional cleaning step using 70% isopropyl alcohol wipes was introduced and the contamination rate was re-audited in 100 samples. The contamination rate was reduced to 6% of handset swabs and 4% of keypad swabs. A high initial rate of bacterial contamination of re-usable analgesia infusion pumps was significantly reduced by the implementation of a simple, additional cleaning procedure.
