Brief Summary
This study evaluates the effect of a multilayer skin dressing (Mepilex) placed on the sacrum or a fluid filled pad (LiquiCell) on risk factors for pressure injuries under conditions consistent with military long-distance transport or prolonged field care. Participants will be assigned to one of six groups - air transport, air transport on a spinal immobilization surface with or without Mepilex or on a field stretcher with or without LiquiCell.

Outcome Measures
Primary Outcomes (5)
Change in Interleukin-1/Total Protein (Skin)
Skin cytokine (IL-1) and total protein will be obtained using a small strip of specialized tape placed on the sacrum/buttocks. After 1-minute application the tape is removed and analyzed for quantity of interleukin-1 (indicator of skin irritation)
Baseline through study completion - approximately 120 minutes
Change in Transcutaneous Tissue Oxygen (TcPO2)
Tissue oxygen is measured continuously on the sacrum using a noninvasive sensor and on the midsternum (midchest) as a control
Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
Change in Skin Moisture (Epidermal and Subepidermal)
Two components of skin moisture will be measured on the sacrum using the Delfin MoistureMeter. The epidermal moisture, which reflects perspiration and subepidermal moisture , which reflects water content of the tissues. The values range from 1-80, with higher numbers reflecting increased moisture.
Baseline (before lying down) and after 120 minutes supine
Change in Skin Temperature
Skin temperature will be measured continuously on the sacrum using a laser doppler probe.
Measured continuously during the baseline (sidelying), supine (120 minutes) and post-sidelying (15 minutes) periods
Change in Skin Interface Pressure
The pressure between the support surface and the skin will be measured continuously during the supine position using the X Sensor system. This system measures force/unit area (e.g., pressure). The peak and average pressure on the sacrum/buttocks will be measured.
Continuously during the supine phase of the study (120 minutes)
Secondary Outcomes (1)
Change in Pressure-Discomfort (Category Partitioning Scale-50)
The score will be obtained at baseline and every 30 minutes in the supine position (total 5 measurements).

Interventions
Mepilex Border Sacrum dressing is a multi-layered soft silicone dressing that is a recommended strategy to augment standard nursing interventions (i.e., repositioning, offloading) to prevent pressure injuries. The dressing will be placed on the sacrum.
LiquiCell is a thin layer of low-viscosity fluid contained in a series of bursa-like pouches. Baffles within each pouch channel the liquid to disperse pressure and the volume of liquid in the pouch is so small that there is no pressure-build up. LiquiCell is available commercially as a 36 X 18-inch mattress overlay (LiquiCell Shear Reducing Mattress Overlay) with a soft pliable top and a non-slip bottom. The overlay is positioned from the shoulders to below the hips to minimize shear.
