Resumo
Background: Neuropathic and venous leg ulcers are chronic wounds associated with devitalized tissue
and recurrent infection. Management should be guided by accurate tissue assessment, including the use
of planimetry, which provides tissue types as a percentage of the total wound bed surface area.
Objective: This innovative study aimed to assess and identify the wound bed tissues, as a percentage, of
neuropathic and venous ulcers using digital planimetry, providing support to nurses optimize the management
of necrotic tissues and, consequently, to avoid wound infection.
Methods: This cross-sectional study enrolled 24 patients with chronic wounds who were assessed from
January to March 2021 at the Wound Outpatients Clinic. The wound photographs were analyzed using
Image J 1.53e and a smartphone with WoundDoc Plus® 2.8.2 via digital planimetry. Statistical analyses
were performed using the binomial test, t-test, and Mann-Whitney.
Results: Median wound areas (p = 0.3263) did not differ between the group with 2 or 3 risk factors for
delayed healing (Md: 31.7) and the group with up to 1 risk factor (Md: 5.3). A low exudate level was
associated with the up-to-1-risk-factor-for-delayed-healing group (p = 0.0405), while a medium level was
associated with the two-or-three-risk-factor group (p = 0.0247). A heat map displayed the tissue percentages
in the wound bed. In the group with 2 or 3 risk factors for delayed healing, 91.7% (11/12) had less
than 70% granulation tissue, which was the primary factor for this group (p < 0.0 0 01). Additionally, 66.7%
(8/12) of patients with 2 or 3 risk factors for delayed healing exhibited discolored and/or dark red granulation
tissue as the primary factor (p = 0.0130).
Conclusion: This novel identification of wound area and tissue types as a percentage, using digital
planimetry, can play a crucial role in assisting nurses in decision-making related to the appropriate management
of devitalized tissues. Furthermore, this measurements may facilitate the conducting of virtual
wound consultations and offer valuable support in the development of protocols aimed at preventing
infection and biofilm formation in the wound bed.
