Use of surface temperature scanner and thermography to evaluate the surface temperature of face and palm in thoracoscopic t2-sympathectomy

30 hyperhidrosis palmaris patients (21 female, 9 female; average age 24.5 y/o) were randomly chosen to evaluate the surface temperature changes during the operation of thoracoscopic T2-sympathectomy. 3 selected points on bilateral palms (thenar area, hypothenar area, middle finger tip) and 2 selected points on bilateral face (cheek, nasal ala) were used to measure the surface temperature changes by using surface temperature scanner. They were measured during the period of preanesthesia, post-anesthetic induction, 3 mins. after left T2sympathectomy, 3 mins. after right T2-sympathectomy, and 30 mins. after surgery. Infrared thermography was also used to record the surface temperature changes of the face. The comparison of the surface temperature was as follows: left side right side pre-operative post-operative pre-operative post-operative thednar 30.12±2.24 33.17 1.33 29.86±2.17 33.21 ±1.49 mid-finger 28.33±3.33 33.90±0.88 28.45±3.54 33.94±1.55 hypo-thenar 30.09 ±2.40 33.12 ±2.36 30.26 ±2.34 33.96 ±0.90 alanasi 32.78±1.49 33.25 ±1.22 32.52±1.99 33.26±1.15 cheek 32.16 ±1.95 33.85 ±1.05 31.96 ±1.70 34.07 ±1.05 The result showed that the increase in facial surface temperature was not as great as the palm but the increase was clinically significant. And as a conclusion, in this preliminary study, thoracoscopic T2-sympathectomy do have the similar vascular effect as stellate ganglion blockade.Though the vascular effect was small in magnitude, it may be of clinical value.
