| 摘 要： | 目的：观察不同波长激光和不同激光能量密度照射家兔耳静脉后的温度改变。方法：采用立体数码体视显微镜,定量测量10只家兔（0只耳朵、80个区域）的静脉主干和I级分支的平均管径大小。采用PDL585nm脉冲染料激光和长脉宽1064nm Nd：YAG激光,分别对5只家兔（10只耳朵、40个区域）的静脉进行激光照射。PDL585nm激光能量密度分别为6、7、8、9、10J/cm^2,1064nm Nd：YAG激光能量密度分别为14、160、180、200、220J/cm^2。利用数码热敏温度仪测量激光照射后的兔耳皮肤温度改变。结果：家兔耳静脉的主干静脉管径为（1.0120±0.1900）mm,I级分支静脉管径为（0.4523±0.1074）mm。PDL585nm激光照射后,兔耳皮肤温度即刻升高至39.9℃～46.0℃;1064nm Nd：YAG激光照射后,兔耳皮肤温度即刻升高至38.6℃～45.4℃。结论：脉冲染料激光PDL585nm、1064nmNd：YAG激光照射均致兔耳皮肤温度升高,并与能量密度呈正比。
