Various methods have been used to obtain blood samples from unrestrained rhinoceros. Without extensive prior training, the results are generally poor due to pain avoidance reactions. However a new dermal anesthesia technique previously used in humans, an eutectic mixture of lidocaine and prilocaine, made it possible to obtain blood samples from the ear veins of one male and two female white rhinoceros (Ceratotherium simum simum) and five full-thickness skin punch biopsies and subsequent suturing on unrestrained rhinoceros. In all animals, the procedures elucidated neither limb withdrawal nor head shake and were regarded as painless.
人们已经使用了各种方法从不受约束的犀牛身上采集血样。如果没有广泛的预先训练，由于犀牛的疼痛回避反应，结果通常很差。然而，一种先前用于人类的新型皮肤麻醉技术，即利多卡因和丙胺卡因的共晶混合物，使得从一头雄性和两头雌性白犀牛（南方白犀指名亚种）的耳静脉采集血样以及对不受约束的犀牛进行五次全层皮肤打孔活检并随后缝合成为可能。在所有动物身上，这些操作均未引发肢体退缩或摇头反应，且被认为是无痛的。
