Exudate management with a next-generation multilayered foam dressing in traumatic and surgical wounds: a prospective,...

The aim of this study was to evaluate the efficacy, performance and safety of ConvaFoam (Convatec Ltd., UK), a next-generation multilayered foam dressing, in indicated surgical and traumatic wounds.

This prospective, multicentre, open-label study (ClinicalTrials.gov: NCT05632276) evaluated ConvaFoam dressings in surgical and traumatic wounds. Eligible patients were managed with ConvaFoam dressings in accordance with their instructions for use (maximum seven-day wear time) for ≤4 weeks. The primary endpoint was the proportion of patients and total dressings with excellent exudate management (defined as absence of strikethrough or periwound maceration). Secondary endpoints included: exudate management in dressings worn for seven days; healing rate; wear time; pain on application; usability; and safety.

The study enrolled 52 patients (mean age: 48.2 years) with surgical (54%) or traumatic (46%) wounds. Median dressing wear time was five days (interquartile range: 1-7 days). Among patients who completed the study, 81% (38/47) were observed to have achieved excellent exudate management throughout all wound care visits (90% confidence interval (CI): 71, 90%). Excellent exudate management was also observed in 93% (209/224) of total dressings applied (90% CI: 90, 97%), including in 96% (47/49) of dressings worn for seven days. Only one patient in the study experienced periwound skin maceration at any study timepoint. Wound healing was observed in 93% of surgical wounds and 25% of traumatic wounds during the study period. Low levels of pain and high user satisfaction as per numeric pain scale and utility questionnaire, respectively, were reported.

ConvaFoam dressings demonstrated excellent exudate management in >90% of dressing changes, and may promote an optimal environment for healing in surgical and traumatic wounds.
