Evaluating A Chitosan Lactate Gelling Microfibre Dressing In Complex Wound Environments: A Clinical Case Series​

Introduction

This case series examined the effectiveness of a chitosan-based wound dressing (MaxioCel®) in managing complex wounds across varied patient demographics. The wounds evaluated comprised of 1 x Pressure Ulcer, 3 x Cavity Wounds, 1 x Leg Ulcer (5 wounds in total).​

Method

Following local guidelines and with patient consent, a controlled evaluation was conducted on five patients aged from 20-95 years, with various wound types, co-morbidities, and wound durations of between 5 days to 12 months. Appropriate secondary dressings were selected during treatment. Wound improvement rates were monitored, with quantitative and qualitative assessments conducted at the initial assessment, after seven days, and a final evaluation one week later. The frequency of dressing changes was adapted according to the requirements of each wound.​

Results

  • All wounds showed significant clinical improvement with the
    chitosan-based dressing.
  • Over 14 days wound surface area reduced from average 8.4cm2 to 5.4cm2.
  • Closure of three wounds was achieved and with two wounds showing improvement.
  • Observations of wound bed tissue revealed increased autolytic debridement of sloughy and necrotic tissue with granulation and epithelialisation tissue improved as a result.
  • No deterioration of the surrounding skin was noted.
  • All clinicians stated they would continue to use the chitosan dressing and recommend it to other healthcare professionals.

Case Study

A 55-year-old female patient who underwent skin-sparing mastectomy and immediate reconstruction with a tissue expander. Post-operatively, a wound developed in the right
chest cavity.

Wound was managed with a hydrofibre dressing
(Aquacel®) with dressing changes every three days.

Initially measuring 1cm length x 1cm Wide x 1cm Deep, the wound
showed significant improvement with MaxioCel® treatment, reducing in size over 14 days and completely healing. The patient experienced no pain throughout the treatment.

“MaxioCel demonstrated excellent performance, absorption capacity, and the promotion of healing, with healthcare professionals noting the product’s activation of the healing process.”


Conclusion

This evaluation demonstrated notable clinical improvements in wounds treated with MaxioCel. The dressing had a positive impact on previously static non-healing wounds. All other wound parameters showed either
improvement or no deterioration with high levels of user satisfaction. These findings support the consideration of this dressing particularly in static and complex non-healing wounds.
