Dispensing surgical gloves onto the open surgical gown pack does not increase the bacterial contamination rate

In implant surgery air and surface contamination have become important factors in post-operative wound infection. We established the rate of contamination of surgical gown packs and found that dropping gloves onto the open gown pack prior to scrubbing had no effect on it. Ninety-six contact plates were used for this study, which was carried out during clean orthopaedic operations in one operating room. The overall rate of contamination was 65%. Most of the contaminants were skin commensals. The rate of contamination was 67% when gloves were dropped onto the gown pack compared with 63% when opened and presented to the scrubbed and gowned theatre staff. However this difference was statistically not significant. The high rate of contamination was probably due to the gown packs having been left opened for too long. This delay arose because each gown pack had three gowns and would have been avoided if single gown packs had been used.
