Wounds. 2012 May;24(5):138-45.
The present study sought to estimate the hemodynamic effects inside wounds after applying infrared thermography. Clinical results were analyzed to evaluate any correspondence with hemodynamic events occurring inside the wounds.
Group 1 consisted of 20 patients with venous leg ulcers (12 women, 8 men). Patients from group 1 received 1 high-voltage stimulation (HVS) procedure. Group 2 consisted of 23 patients (16 women, 7 men). Patients from group 2 received 1 ultrasound (US) procedure. Group 3 consisted of 21 patients (13 women, 8 men). Patients from group 3 received 1 low-level laser therapy (LLLT) procedure. Group 4 consisted of 23 patients (15 women, 8 men). Patients from group 4 received 1 compression therapy (CT) procedure. Group 5 consisted of 19 patients (11 women, 8 men). Patients from group 5 received 1 quasi-CT procedure. Infrared thermography was used to monitor arterial hemodynamic effects for each ulcer. Infrared thermography, based on analysis of wound surface temperatures, was used to reflect normal or abnormal arterial circulation in capillaries. The average and maximal temperatures before and after each physical procedure were measured 5, 10, 15, and 30 minutes afterward.
The application of HVS and LLLT did not change the temperature inside the wounds. A significant temperature increase was noted after application of US and CT. The quasi-CT induced a thermal effect (only for a few minutes), but was not as intense as the effect of the compression stockings. The measurements showed a prolonged and steady thermal effect.
The hemodynamic effect (improvement of arterial microcirculation inside the venous leg ulcer) is one of the most significant biophysical mechanisms of healing after clinically efficient compression therapy. Hemodynamic reactions are not basic mechanisms of high voltage stimulation and ultrasound therapy during the healing of venous leg ulcers. Computed thermography is a simple and useful tool to measure hemodynamic effects in wound healing. .
本研究旨在评估应用红外热成像技术后伤口内部的血流动力学效应。分析临床结果以评估其与伤口内部发生的血流动力学事件之间的相关性。
第1组由20例下肢静脉溃疡患者组成（12名女性，8名男性）。第1组患者接受1次高压刺激（HVS）治疗。第2组由23例患者组成（16名女性，7名男性）。第2组患者接受1次超声（US）治疗。第3组由21例患者组成（13名女性，8名男性）。第3组患者接受1次低强度激光治疗（LLLT）。第4组由23例患者组成（15名女性，8名男性）。第4组患者接受1次压迫治疗（CT）。第5组由19例患者组成（11名女性，8名男性）。第5组患者接受1次准压迫治疗。采用红外热成像技术监测每个溃疡的动脉血流动力学效应。基于伤口表面温度分析的红外热成像技术用于反映毛细血管中正常或异常的动脉循环。在每次物理治疗前及治疗后5、10、15和30分钟测量平均温度和最高温度。
应用HVS和LLLT后伤口内部温度未发生变化。应用US和CT后温度显著升高。准压迫治疗产生了热效应（仅持续几分钟），但不如弹力袜的效果强烈。测量结果显示出持续且稳定的热效应。
血流动力学效应（改善下肢静脉溃疡内部的动脉微循环）是临床有效压迫治疗后愈合的最重要生物物理机制之一。血流动力学反应不是下肢静脉溃疡愈合过程中高压刺激和超声治疗的基本机制。计算机热成像技术是测量伤口愈合中血流动力学效应的一种简单且有用的工具。
