The left surgical hip wound also produced high levels of exudate which was managed with topical negative pressure (TNP) treatment. Healthy granulation tissue, wound exudate reduced. Healthy granulation, wound exudate - negligible. Wound assessment: At week 5 when referred to TVN - circular wound approx 2.5cm in diameter
located over L. hallux, with fragile, deep red granulation tissue that bled easily. Extensive peri-wound erythema extending approx. 3 cm to mid-foot and the adjoining digit was swollen, hot to touch and Little/no progress was achieved with antimicrobials (Ag dressings/systemic antibiotics), (Table 1). This painful.

It was decided to focus on managing the wound environment using an absorbent dressing that possesses Hydration Response Technology (HRT). Key components of HRT include its powerful osmotic pull whilst maintaining a moist wound healing environment. HRT has the An overview of intervention and wound response is presented in Table 1. It can be seen that wound ability to draw wound fluid into the dressing matrix (where the aqueous component is bound) together progress was not only stalled but that deterioration was evident. An increase in wound exudate pro- with the accompanying free floating bacteria. Prompt management of the high exudate volume and duction in conjunction with stalled healing is regarded as a clinical indicator of wound infection. Positive the associated bacterial load swiftly returned the wound bed to an environment conducive to healing. wound cultures for MRSA in conjunction with the increase in wound exudate lead to the conclusion Effcient management of exudate and bacterial load are key components of Wound Bed Preparation. that the wound was infected with MRSA.
The initial management strategy of using active mechanisms (antimicrobials) together with moderate absorbent capacity dressings had failed to manage the bioburden or the exudate volume. Using sorbion sachet S with HRT allowed this highly absorbent, non traumatic dressing to bind the exudate, sequester bacteria andmodulate protease activity whilst maintaining a moist wound environment. Apart from woundresolution the additional benefits were reduced costs and a vastly improved quality of life for the patient.
While this is a single case study the question is posed as to the perceived need for widespread antimicrobial use. Further studies are welcomed.
