Availability of measurement of salivary alpha-amylase activity for evaluation of surgical stimuli and postoperative pain

在本研究中，在全麻下气管插管和切皮后，唾液α-淀粉酶活性(SAA)显著升高，表明交感神经活动。相反，围手术期和术后的SAA值与SAA、视觉模拟评分(VAS)和术后48小时内止痛药的使用无关。这些结果表明，SAA的测量可能是一种评估全身麻醉下伤害性刺激的方法，然而，评估术后疼痛可能是困难的。

In this study, salivary alpha-amylase activity(sAA) which indicate of sympathetic activity was significantly induced after tracheal intubation and skin incision under general anesthesia. In contrast, perioperative and postoperative sAA values did not associate with sAA, VAS(visual analogue scale) and analgesic agent usage during 48 hours after operation. These results suggest that measurement of sAA might be a method for evaluation of noxious stimuli under general anesthesia, however, it is probably difficult to assess postoperative pain.
