Chronic Wound Debridement in an Acute Setting to Facilitate Improved Management Objectives Utilising Bioactive Microfibre Gelling (BMG™) Technology​

Introduction

All wounds can be serious, have a negative impact on individuals, their families and healthcare services. Wounds often contain necrotic or sloughy tissue, which can harbour bacteria and biofilm acting as a barrier to healing. Debridement is an integral part of wound management. 

In 2023 the Tissue Viability Team was presented with the opportunity to evaluate a 100% pure Chitosan dressing, derived from chitin, with Bioactive Microfibre Gelling (BMG™) Technology. Studies have found chitosan to have several properties that aid wound healing (Dai Tet al 2011). 

The aim of this study was to investigate the potential for autolytic debridement using the BMG technology dressing (MaxioCel), to facilitate wound healing. 

Method

Evaluation of 10 inpatient case studies over a 2-week period in the acute setting.

The average patient age was 78 years old. 70% female, 30% male.


Wound types included: Pressure ulcer (6) Surgical wound (3) Biopsy wound (1) (Figure 1).

At initial assessment, 50% of wounds were identified as ‘deteriorating’, 40% as ‘static’, and only 10% as ’progressing.’  

Results

In 8 cases there was a visible reduction in devitalised tissue, decrease in wound size and improvement of the wound bed. Within just 2 weeks there was a significant improvement in average wound bed condition, with slough reducing from 85% to 36.25%, and granulation tissue increasing from 14% to 63.12% (Figure 2). 

A noticeable decrease in signs of infection was observed and odour eliminated due to the dressing’s antibacterial anti biofilm properties.

In one patient the use of the BMG dressing facilitated earlier application of Negative Pressure Wound Therapy (NPWT) after one week due to improved wound bed status.

Within just two weeks, MaxioCel demonstrated an effective option for wound debridement, facilitating the maintenance of a healthy wound bed.


Conclusion

Within just two weeks, the BMG dressing (MaxioCel) demonstrated an effective option for wound debridement, facilitating the maintenance of a healthy wound bed.
