Hospital-acquired pressure ulcer/injury (HAPU/I) often occurs postoperatively despite preventative interventions. The authors recently found an increasing incidence of HAPU/I in patients having prolonged operating room (OR) procedures in both the bent knee and lithotomy positions.
The aim of this study was to measure and compare 2 different OR surfaces in both the supine with bent knees position and the supine in lithotomy position. The authors sought to identify the most effective pressure redistribution surface in different positions to prevent HAPU/I in surgical patients.
Using a pressure mapping device, the authors measured and compared 5 volunteers on the standard OR surface and on the standard surface with the static, air-filled cushion on top.
Use of the static, air-filled seat cushion placed on top of the standard OR surface resulted in lower peak pressures and higher skin contact surface area than the standard OR surface alone.
This study showed that use of the static, air-filled seat cushion on top of the standard OR surface resulted in superior pressure redistribution properties in both the supine with bent knees position and supine in lithotomy position compared with the standard OR surface alone.
尽管采取了预防措施，术后仍常发生医院获得性压疮/损伤（HAPU/I）。作者最近发现，在屈膝和截石位接受长时间手术的患者中，HAPU/I 的发生率呈上升趋势。
本研究旨在测量和比较两种不同手术床面在仰卧屈膝位和仰卧截石位的效果。作者旨在确定不同体位下最有效的压力再分布表面，以预防手术患者的 HAPU/I。
使用压力映射设备，作者测量并比较了 5 名志愿者在标准手术床面和标准手术床面加静态充气垫的情况。
与标准手术床面相比，在标准手术床面上加用静态充气座垫可降低峰值压力并增加皮肤接触面积。
本研究表明，与标准手术床面相比，在标准手术床面上加用静态充气座垫可改善仰卧屈膝位和仰卧截石位的压力再分布性能。
