The number of fluctuations of skin conductance per second correlates with postoperative pain. The aim of this prospective study was to test the cut-off value for the number of fluctuations of skin conductance per second obtained from a previous study. Seventy-five patients were asked to quantify their level of pain on a numeric rating scale (0-10) in the recovery room. The number of fluctuations of skin conductance per second was recorded simultaneously. The number of fluctuations of skin conductance per second was different between patients with no (0.07), mild (0.16), moderate (0.28) and severe pain (0.33); p < 0.001. The tested cut-off value for the number of fluctuations of skin conductance per second (0.1) distinguished a numeric rating scale </= 3 from > 3 with 88.5% sensitivity and 67.7% specificity. The number of fluctuations of skin conductance per second may be a useful means of assessing postoperative pain.
皮肤电导每秒波动次数与术后疼痛相关。这项前瞻性研究的目的是检验先前研究得出的皮肤电导每秒波动次数的临界值。75名患者被要求在恢复室用数字评分量表（0 - 10）对自己的疼痛程度进行量化。同时记录皮肤电导每秒波动次数。无痛（0.07）、轻度疼痛（0.16）、中度疼痛（0.28）和重度疼痛（0.33）患者的皮肤电导每秒波动次数不同；p < 0.001。经测试的皮肤电导每秒波动次数的临界值（0.1）区分数字评分量表≤3和>3时，敏感度为88.5%，特异度为67.7%。皮肤电导每秒波动次数可能是评估术后疼痛的一种有用方法。
