通过测定正常人在１０℃冷水浸手后的手指皮温（Ｔｓ）和血管机能，本研究结果表明浸手３分钟时测定，Ｔｓ显著下降（Ｐ＜０．０１），１８分钟时中指和无名指的Ｔｓ轻度升高。手指血管弹性和顺应性减弱，收缩期血流速度峰值（Ｐ＜０．０１）及平均血流速度显著降低。该研究结果提示，局部冷接触后手指血流速度、血管弹性和顺应性的变化与低温环境中手指生理功能减弱甚或损伤有关。
By measuring the finger temperature (Ts) and vascular function in normal subjects after cold water immersion at 10 ° C, the results of this study showed that Ts was significantly decreased (P <0.01) at 3 minutes of immersion and at 18 minutes of middle finger and ring finger Ts slightly elevated. Finger elasticity and compliance decreased, peak systolic velocity (P <0.01) and mean velocity decreased significantly. The results suggest that the changes of finger blood flow velocity, blood vessel elasticity and compliance after local cold contact may be related to the weakening or even damage of finger physiology in low temperature environment.
