项目摘要

In order to elucidate quantitatively the levels of the stress in pregnant women during labor, this study was undertaken. Women undergoing labor were divided into the normal labor group and the difficult labor group. Changes in the women's skins temperature(ST), the intensity subjective labor pain as rated on the visual analog scales(VAS) and the midwife's score of labor pain(MS) were analyzed. The women's skin temperature was measured by a computer-linked polygraph system including a fingertip pulse labor pain meter (which uses the fingertip's palmar side skin temperature as an indicator). Using this system changes in ST were displayed on the labor monitor device a real-time basis and uterine contraction curves were depicted. The data obtained in this study were analyzed using computer software.In the normal labor group, ST decreased by 0.2-0.4℃, synchronous with the cycle of labor pain. For both primipara and multipara, ST reached a peak during the first phase of labor. In the second phase, ST was lower in them multipara group than in the primipara group. In the difficult labor group, ST decreased by 0.4-0.7℃ and more time was taken for ST to recover. MS reached a peak during the second phase in both primipara and multipara. Primipara had a peak VAS during the first phase, while I multipara had it during the second phase of labor. The decrease in ST was in a mirror-surface like relationship to changes in VAS and MS. These results suggest that finger tip skin temperature sensitively reflects the labor pain, related stress of women undergoing labor, and this study will be useful in improving the labor care.

为了定量地阐明孕妇在分娩过程中的应激水平，进行了这项研究。将临产妇女分为正常分娩组和困难分娩组。比较两组产妇皮温（ST）、疼痛视觉模拟评分（VAS）及助产士疼痛评分（MS）的变化。这些妇女的皮肤温度是通过一个计算机连接的测谎系统测量的，该系统包括一个指尖脉搏分娩疼痛仪（使用指尖的手掌侧皮肤温度作为指标）。该系统可在产程监护仪上实时显示ST段变化，并绘制宫缩曲线。本研究所获得的数据用计算机软件进行分析，顺产组ST下降0.2-0.4℃，与产痛周期同步。对于经产妇和经产妇，ST在第一产程期间达到峰值。第二阶段经产妇ST低于经产妇。难产组ST下降0.4-0.7℃，ST恢复时间较长。MS在双产妇和经产妇的第二阶段达到高峰。初产妇在第一阶段有一个峰值VAS，而经产妇在第二阶段的劳动力。ST的下降与VAS和MS的变化呈镜面关系。这些结果表明，指尖皮肤温度敏感地反映了分娩疼痛，分娩妇女的相关压力，这项研究将有助于改善分娩护理。
