目的：确定患有和不患有痛经的女性对疼痛的全身处理是否存在差异。方法：对 22 名痛经女性和 31 名非痛经女性进行了研究，包括热刺激的疼痛阈值和阈上强度估计、激光刺激引起的疼痛诱发电位以及月经周期中四次的焦虑评分。结果：痛经和非痛经女性。在整个月经周期的所有四项检查中，痛经女性的疼痛诱发电位潜伏期较长（383.08 +/- 6.8 毫秒与 345.05 +/- 7.0 毫秒，P < .001），阈上疼痛的视觉模拟量表的幅度估计较高（83.29 +/- 2.87 与 63.50 +/- 3.82， P < .001），以及更高的状态焦虑评分（37.69 +/- 1.7 与 29.20 +/- 1.9，P = .002）。 结论：与非痛经女性相比，痛经女性的疼痛感知能力增强。这种疼痛感的增强可能是痛经发展的一部分。 (C) 2001 年由美国妇产科医师学会颁发。
OBJECTIVE: To determine if systemic processing of pain differs in women with and without dysmenorrhea.METHODS: Twenty-two dysmenorrheic women and 31 nondysmenorrheic women were studied by pain threshold and supra-threshold magnitude estimation to heat stimuli, pain-evoked potentials by laser stimuli, and anxiety scores four times across their menstrual cycles.RESULTS: Significant differences were found between dysmenorrheic and nondysmenorrheic women. In all four examinations across the menstrual cycle, dysmenorrheic women had longer latencies of pain-evoked potentials (383.08 +/- 6.8 msec versus 345.05 +/- 7.0 msec, P < .001), higher magnitude estimations on visual analog scale of supra-threshold pain (83.29 +/- 2.87 versus 63.50 +/- 3.82, P < .001), and higher state anxiety scores (37.69 +/- 1.7 versus 29.20 +/- 1.9, P = .002).CONCLUSION: Women with dysmenorrhea show enhanced pain perception compared to nondysmenorrheic women. This augmentation of pain perception may be part of the development of dysmenorrhea. (C) 2001 by the American College of Obstetricians and Gynecologists.
