Thermographic evaluation of skin temperature of the patients with palm hyerhidorsis after endoscopic thoracic sympathectomy using light emitting diode illumination

一种新的牵开器被制成连接三色发光二极管（LED）尖端。该牵开器用于打开胸廓切开术切口。LED连接在牵开器内，LED直接照亮胸腔。LED尖端由三色（红色、黄色和蓝色）微型LED芯片构成。我们测试了三种颜色的波长强度，以建立最合适的LED照明混合。LED照亮胸腔，例如，神经的一些分支、肺动脉和静脉、淋巴结。我们正试图找到适当的LED波强度设置，以区分纵隔器官彼此。这是一种特制的手术室照明设备。观察胸交感神经切断术后皮肤温度的变化。术后早期无汗性病变与体温升高病变有一定的相关性。术后体温有不同程度下降，但无汗症无明显改变。这些发现提示某些交感神经重建障碍会导致受损病灶皮肤温度升高和无汗。

A new retractor was made to attach three-color light emitting diode (LED) tips. This retractor was used to open the thoracotomy incision. The LEDs were attached inside the retracotr, which LEDs directly illuminated the thoracic cavity. LED tips are constructed with three-color (red, yellow, and blue) micro LED dices. We tested the three color wave strength to set up the most proper LED illuminating mixture. LEDs illuminate the thoracic cavity, such as, some branches of the nerve, pulmonary artery and vein, lymph nodes. We are trying to find the proper setting of LED wave strength to distinguish the mediastinal organs from each other. This will be a talor-made lighting in the operating theater.Changes of skin temperature after thoracic sympathecotmy were observed. There were some correlation between the anhidrosis lesion and the increased body temperature lesion in the early postoperative period. Body temperature was decreased some degree, however, anhidrosis lesion did not changed after a long time follow up period. These findings suggest some sympathetic reconstruction disorders will cause in the damaged lesion skin temperature and anhidrosis.
