Objective To map skin temperature kinetics, and by extension skin blood flow throughout normal or abnormal repair of full‐thickness cutaneous wounds created on the horse body and limb, using infrared thermography. Study Design Experimental. Animals S tandardbreds (n = 6), aged 3–4 years. Methods Three cutaneous wounds were created on the dorsolateral surface of each metacarpus and on the lateral thoracic wall. Thoracic skin wounds and those on 1 randomly chosen forelimb healed by second intention without a bandage, whereas contralateral limb wounds were bandaged to induce formation of exuberant granulation tissue ( EGT ). Thermal data were collected from all planned wound sites before the surgical procedure (baseline), and at 24, 48, 96 hours, 1, 2, and 4 weeks after wounding. Data were analyzed using repeated measures ANOVA and a priori contrasts submitted to B onferroni sequential correction. Level of significance was P < .05. Results Cutaneous wound temperature ( CWT ) increased temporally from preoperative period to week 1 postwounding, independently of anatomic location ( P < .0001). CWT of limb wounds was significantly less than that of body wounds throughout healing ( P < .01). CWT of limb wounds managed with bandages and developing EGT was significantly less than that of unbandaged limb wounds, which did not develop EGT ( P ≤ .01). Conclusions CWT varied with anatomic location and throughout healing. CWT of wounds developing EGT was significantly less than that of wounds without EGT .
