Changes in blood blow and skin temperature have been measured in the arms of twenty patients under brachial plexus anaesthesia. A rise in each was noted in every patient. The patients were subdivided into two groups of ten. The anaesthetic administered to the patients of one group contained adrenaline (1 in 100,000), and the patients in the other group received the same anaesthetic but with no added adrenaline. The rise in flow volume, flow velocity and temperature was greater in the group which received adrenaline. The difference in change of flow volume was significant (P less than 0.05), the difference in temperature rise highly significant (P less than 0.01), but the difference in change of flow velocity was not significant.
在二十名接受臂丛神经麻醉的患者的手臂中测量了血流和皮肤温度的变化。每名患者均出现了二者的升高。患者被分为两组，每组十人。给其中一组患者使用的麻醉剂含有肾上腺素（1:100,000），另一组患者接受相同的麻醉剂但未添加肾上腺素。接受肾上腺素的组中血流量、血流速度和温度的升高幅度更大。血流量变化的差异具有显著性（P小于0.05），温度升高的差异具有高度显著性（P小于0.01），但血流速度变化的差异不具有显著性。
