It is understood that Propionibacterium can persist on the skin surface after surgical preparation.
This study from our team at the University of Washington, recognized that Propionibacterium normally reside in the dermal layer which must be transected in surgery. The authors sought to determine the prevalence of propionibacteria in the dermis after surgical skin preparation.
Ten healthy male volunteers underwent surgical skin preparation of the upper back with ChloraPrep. Two 3-mm dermal punch biopsy specimens were obtained through the prepared skin and specifically cultured for Propionibacterium.
Seven of the ten subjects (70%) had positive dermal cultures for Propionibacterium on dermal cultures in spite of ChloraPrep skin preparation. The average time for the cultures to turn positive was 6.8 days.
Comment: Propionibacterium are commonly associated with failure of shoulder arthroplasty, usually presenting with pain, stiffness and implant loosening. This study demonstrates that standard skin preparation does not remove viable Propionibacterium from their location in the skin. Surgical transection of the dermal hair follicles and sebaceous glands where Propionibacterium reside can result in contamination of the surgical wound and to the formation of a persistent biofilm on implanted arthroplasty components.
