(1) Background: Pressure ulcers in the hospital setting occurring within 72 h after surgery are called perioperative pressure injuries. The aim of this study was to provide data for the prevention of perioperative pressure injuries following the use of pressure-relieving overlays by measuring the interface pressures and subjective comfort. (2) Methods: This study is based on a repeated measures design. The subjects included 30 healthy volunteers aged 18 to 57 years. Interface pressures of the sacrum and both heels were measured in the supine position, and the subjective comfort was evaluated with visual analog scale after applying polyurethane foam, gel pad, and egg crate foam for relief. (3) Results: The pressures in the sacrum and both heels were the lowest with polyurethane foam, and the subjective comfort was the highest. (4) Conclusions: Inexpensive polyurethane foam with satisfactory pressure relief is recommended as an overlay for surgical patients.
（1）背景：术后 72 小时内发生于医院环境中的压力性溃疡称为围手术期压力性损伤。本研究旨在通过测量界面压力和主观舒适度为使用减压覆盖物预防围手术期压力性损伤提供数据。
（2）方法：本研究基于重复测量设计。纳入了 30 名年龄在 18 至 57 岁之间的健康志愿者。在仰卧位时测量了骶骨和双侧足跟的界面压力，并在使用聚氨酯泡沫、凝胶垫和蛋盒泡沫缓解后，用视觉模拟评分评估了主观舒适度。
（3）结果：聚氨酯泡沫的骶骨和双侧足跟压力最低，主观舒适度最高。
（4）结论：推荐使用价格低廉且减压效果令人满意的聚氨酯泡沫作为手术患者的覆盖物。
