招募了 446 名普外科、血管外科和妇科外科患者参加一项两中心、双三角序贯随机对照试验，以比较位于标准手术台床垫上的患者与位于干燥粘弹性聚合物垫（Action Products Inc.）上的患者术后压疮的发生率。 222 名患者被随机分配到实验组，224 名患者分配到标准床垫。结果发现，分配到干燥粘弹性聚合物垫的患者的主要终点失败率（压疮）为 11% (22/205)，分配到标准手术台床垫的患者的主要终点失败率为 20% (43/211)。与标准相比，干粘弹性聚合物垫上发生压疮的几率显着降低，圆负 = 0.46，95% 置信区间为 (0.26, 0.82)，P = 0.010。在干燥粘弹性聚合物垫和标准手术台床垫上发生压疮的概率的调整点估计值分别为 0.11 和 0.21。 (C) 1998 Elsevier Science Ltd. 保留所有权利。
Four hundred and forty-six general, vascular and gynaecological surgical patients were recruited to a two centre, double triangular sequential randomised controlled trial to compare the post-operative pressure sore incidence in patients positioned on the standard operating table mattress with those positioned on the dry visco-elastic polymer pad (Action Products Inc.). Two hundred and twenty two patients were randomised to the experimental group and 224 to the standard mattress. The main endpoint failure rate (a pressure sore) was found to be 11% (22/205) for patients allocated to the dry visco-elastic polymer pad and 20% (43/211) for patients allocated to the standard operating table mattress. There was a significant reduction in the odds of developing a pressure sore on the dry visco-elastic polymer pad as compared to the standard, circle minus = 0.46 with 95% confidence interval of (0.26, 0.82), P = 0.010. The adjusted point estimates of the probability of developing a pressure sore on the dry visco-elastic polymer pad and the standard operating table mattress were 0.11 and 0.21 respectively.
