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.
Experimental.
Standardbreds (n = 6), aged 3-4 years.
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 Bonferroni sequential correction. Level of significance was P < .05.
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).
CWT varied with anatomic location and throughout healing. CWT of wounds developing EGT was significantly less than that of wounds without EGT.
使用红外热成像技术描绘马身体和四肢全层皮肤伤口正常或异常修复过程中的皮肤温度动力学变化,并由此推断皮肤血流情况。
实验性研究。
3至4岁的标准bred马(n = 6)。
在每个掌骨的背外侧表面和胸侧壁上制造三个皮肤伤口。胸部皮肤伤口和随机选择的一个前肢上的伤口通过二期愈合,不使用绷带,而对侧肢体伤口进行包扎以诱导过度增生性肉芽组织(EGT)形成。在手术前(基线)以及受伤后24、48、96小时、1、2和4周,从所有计划的伤口部位收集热数据。使用重复测量方差分析和先验对比进行数据统计,并进行Bonferroni序贯校正。显著性水平为P <.05。
皮肤伤口温度(CWT)从术前到受伤后第1周随时间升高,与解剖位置无关(P <.0001)。在整个愈合过程中,肢体伤口的CWT显著低于身体伤口(P <.01)。用绷带处理并形成EGT的肢体伤口的CWT显著低于未包扎且未形成EGT的肢体伤口(P≤.01)。
CWT随解剖位置和整个愈合过程而变化。形成EGT的伤口的CWT显著低于未形成EGT的伤口。
