Summary
Objectives: To evaluate negative pressure wound therapy (NPWT) for treatment of complicated wounds
in dogs.
Study type: Retrospective multicentre study.
Materials and methods: Dogs (n = 50) undergoing open wound treatment were classified according to treatment
method used: bandage (Group A, n = 7), NPWT (Group B, n = 18), and foam dressing (Group
C, n = 25). Pairs of patients matched based on wound conformation, localization, and
underlying cause were compared between Group A and C (n = 7 pairs) and between groups
B and C (n = 18 pairs) in terms of duration of previous treatment, time to closure,
and complications.
Results: Signalment, antibiotic medications, antiseptic treatment, and bacterial status of
wounds were comparable between groups. The duration of previous treatment was significantly
higher in patients assigned to Group B (p = 0.04) compared to Group C, while no significant
difference was found between groups A and B. Total time to wound closure was significantly
shorter in Group C compared to Group A (p = 0.02) and in Group B compared to Group
C (p = 0.003). Wounds treated with NPWT suffered significantly less complications
(p = 0.008) and were significantly less septic during treatment (p = 0.016) than wounds
treated with a foam dressing.
Conclusion: This study shows that time to healing was halved in NPWT treated patients compared
to foam dressing treated patients, which in turn healed faster than patients treated
with conventional bandage, underlining the value of NPWT therapy for the treatment
of complicated wounds.
