Outcomes
Primary outcome [1] 269094 0
Ability to transmit topical negative pressure to the wound bed (assessed by odour, reduction of oedema, development of vascular granulations, cleanliness, wound area) with assessment by an independent specialist woundcare nurse, photographic analysis and wound area measurement.
Timepoint [1] 269094 0
Every 2-3 days for 8 weeks.
Secondary outcome [1] 276920 0
Safety (assessed by absence of local or systemic effects attributable to the new material). This can only be assessed by direct comparison with the control material, both within the study and against historical experience.
Timepoint [1] 276920 0
Every 2-3 days for 8 weeks.
