Saline irrigation has been shown to be both experimentally and clinically
efficacious in decreasing bacterial contamination as well as decreasing infection
rates. The dynamics of irrigation delivery fall into two primary categories:
simultaneous and intermittent irrigation. An important component to irrigation
therapy is distribution of irrigation solution to hard-to-reach areas of a wound
bed, including undermining and fissure-like structures. Here we test the
effectiveness of simultaneous irrigation to fill the irregular structures of a
wound bed. In order to visualise the dynamic movement of irrigation solution,
three-dimensional wound models were constructed using clear synthetic ballistic
gel. Wounds with the aforementioned characteristics were carved into the
ballistic gel with varying area, depth and volume. All three wounds were dressed
as per manufacturer's instructions. Data demonstrate that simultaneous irrigation
is effective in reaching all parts of a wound bed in wound models that have both
undermining and tunnelling, and irrigation effectively saturates bridged wounds.
Finally, this study shows that there is constant turnover of irrigation solution
in the wound that is driven more by administration volume and less by flow rate.
These data show that simultaneous irrigation is an effective technique for
delivering irrigation solution to both simple and complex wounds.
