血浆儿茶酚胺的放射酶测定法和高度便携的非侵入性抽血泵的最新发展使得对实际应激的生理反应的调查成为可能。由于血浆儿茶酚胺的半衰期是如此短暂，必须采取细致的护理，以获得血液样本一致的相对于一个维斯于应激浸泡的经验。这些观点在一项对10名年轻医生在公众演讲压力下的研究中得到了证明。血浆肾上腺素水平在公众演讲的初始时刻和演讲的中间时刻之间有显著差异。这些差异大到足以影响在比较公众演讲价值与基准价值时得出的结论。
The recent development of radioenzymatic assays for plasma catecholamines and of highly portable nonobtrusive blood withdrawal pumps makes possible the investigation of the physiological response to actual stress. Because the half-life of plasma catecholamines is so brief, meticulous care must be taken to obtain blood samples consistently vis-a-vis the stress immersion experience. These points are demonstrated in a study of 10 young physicians under the stress of public speaking. Plasma epinephrine levels differ significantly between the initial moments of public speaking and the middle moments of speaking. These differences are large enough to affect the conclusions reached in comparing public speaking values with baseline values.
