ABSTRACT

Excessive pain during medical procedures is a pervasive health challenge. This study tested the (additive) analgesic efficacy of combining hypnotic analgesia and virtual reality (VR) pain distraction. A single blind, randomized, and controlled trial was used to study 205 undergraduate volunteers aged 18 to 20. The individual and combined effects of hypnotic analgesia (H) and VR distraction on experimentally induced acute thermal pain were examined using a 2 X 2, between-groups parallel design (4 groups total). Participants in groups that received hypnosis remained hypnotized during the test phase pain stimulus. The main outcome measure was “worst pain” ratings. Hypnosis reduced acute pain even for people who scored low on hypnotizability. As predicted, H+ VR was significantly more effective than VR distraction alone. However, H+ VR was not significantly more effective than hypnotic analgesia alone. Being hypnotized during thermal pain enhanced VR distraction analgesia.

摘要

医疗过程中的过度疼痛是一项普遍存在的健康挑战。本研究测试了催眠镇痛和虚拟现实 (VR) 疼痛分散相结合的（附加）镇痛效果。一项单盲、随机和对照试验用于研究 205 名 18 至 20 岁的本科志愿者。使用 2 X 2，在-组平行设计（共 4 组）。接受催眠组的参与者在测试阶段疼痛刺激期间保持催眠状态。主要结果衡量标准是“最严重的痛苦”评级。即使对于催眠能力得分低的人，催眠也能减轻急性疼痛。正如预测的那样，H+ VR 比单独使用 VR 分散注意力更有效。然而，H+ VR 并不比单独使用催眠镇痛更有效。在热痛期间被催眠增强了 VR 分散镇痛。
