Use of a gelling fibre dressing in complex surgical or chronic wounds: a case series.

OBJECTIVE
To evaluate the safety and performance of a gelling fibre dressing, with respect to wound exudate management, maceration and periwound skin conditions.


METHOD
Complex (non-healing) surgical or chronic wounds healing by secondary intention were treated with a gelling fibre dressing (Biosorb, Acelity) as part of a prospective, two-centre case series product evaluation study. Dressing performance was evaluated at each change, and weekly for up to four weeks or until the wound healed, if this was in less than four weeks. The main outcome measure was dressing performance, wound bed and periwound skin condition.


RESULTS
A total of 15 patients, aged 26-87 years, were enrolled; 10 patients (66.7%) presented with chronic wounds including venous leg ulcers (VLUs), arterial leg ulcer, one mixed leg ulcer, pressure ulcer (PU), and diabetic foot ulcers (DFUs). The remaining wounds (33.3%) were postsurgical complex wounds healing by secondary intention, located in the upper leg, foot, abdomen, and sacrum. Mean wound area was 22.6±36.6cm2 (range: 1.3-144.0cm2). Treated wounds showed complete granulation in eight (53.0%) wounds, 75% granulation coverage in two (13.3%) wounds, 50% coverage in three (20.3%), and 25% coverage in two (13.3%) wounds. Patients evaluated the dressing effectiveness as 'excellent' or 'very good' in 45% of cases, 'moderate' in 45%, and 'poor' in 10% of cases. Results of Visual Analogue Scale (VAS) showed 70% of patients rated their pain as 'low' and 30% as 'moderate' at dressing removal. Clinicians' evaluation of dressing ability to absorb and retain wound exudate was rated 'excellent' or 'very good' in 80% of cases, and moderate in 20% and poor in 10% of cases. Overall, clinicians' impression of the dressing performance was reported as 'excellent' or 'very good' in 80% of cases and 'moderate' in 20% of cases. No patient had to be removed from the study due to adverse events directly related to the dressing or its performance.


CONCLUSION
These clinical findings suggest the new gelling fibre dressing to be safe and effective in wound treatment of complex (non-healing) surgical or chronic wounds, to manage exudate effectively, and to optimise the conditions of wounds healing by secondary intention.
