The present study was designed to determine the effect of the application of cold or heat on the sensation of pricking pain based on autonomic responses. Electrical stimulation was applied to the antebrachium or brachium of subjects as an artificial pricking pain, and skin blood flow (BF) and skin conductance level (SCL) at the fingertip were measured. Pain sensation was evaluated using the visual analog scale. Pain stimulation produced a significant increase in SCL and a significant decrease in BF at both the antebrachium and brachium. Application of cold to the stimulation site using an ice-water pack reduced BF and SCL responses and pain sensation. Application of heat using a hot water bottle caused a significant increase in pain sensation and enhancement of BF and SCL responses. These results suggest that application of cold promotes relief of pricking pain sensation and suppression of autonomic responses, and that application of heat has no such effect. It is important that nurses ascertain the type of pain or source of pain and take proper measures for its relief.
本研究旨在基于自主神经反应确定冷或热的应用对刺痛感的影响。对受试者的前臂或上臂施加电刺激作为人工刺痛，测量指尖的皮肤血流量（BF）和皮肤电导水平（SCL）。使用视觉模拟量表评估疼痛感觉。疼痛刺激使前臂和上臂的SCL显著增加，BF显著降低。使用冰袋对刺激部位进行冷敷可降低BF和SCL反应以及疼痛感觉。使用热水瓶进行热敷会使疼痛感觉显著增加，并增强BF和SCL反应。这些结果表明，冷敷可促进刺痛感的缓解和自主神经反应的抑制，而热敷则没有这种效果。护士确定疼痛类型或疼痛来源并采取适当的缓解措施非常重要。
