A clinical investigation was conducted concerning the effects of a newly designed double-layer air-cell overlay in preventing the onset of pressure ulcers for patients with a Braden scale score of < or = 16, and who require a head-elevated position of 45 degrees or higher. A randomised controlled trial was undertaken involving 82 patients from a general hospital ward using one of the following three support surfaces: a double-layer air-cell overlay, a single-layer air-cell overlay or a standard hospital mattress. A significantly lower percentage of patients using the double-layer air-cell overlay developed pressure ulcers (3.4%) compared to 19.2% and 37.0% for those patients using the single-layer air-cell overlay and standard mattress respectively. Based on these findings, a double-layer air-cell overlay should be more effective in preventing the onset of pressure ulcers than either a single-layer air-cell overlay or a standard hospital mattress for subjects requiring head elevation.
针对一种新设计的双层气圈垫对Braden量表评分≤16且需要头部抬高45度或更高体位的患者预防压疮发生的效果进行了一项临床研究。采用随机对照试验，选取了一家综合医院病房的82例患者，使用以下三种支撑面之一：双层气圈垫、单层气圈垫或标准医院床垫。与分别使用单层气圈垫和标准床垫的患者相比，使用双层气圈垫的患者发生压疮的比例显著更低（3.4%），而使用单层气圈垫和标准床垫的患者发生压疮的比例分别为19.2%和37.0%。基于这些发现，对于需要头部抬高的受试者，双层气圈垫在预防压疮发生方面应比单层气圈垫或标准医院床垫更有效。
