Interface pressure redistribution on skin during continuous lateral rotation therapy: A feasibility study

Area of Science:

• Critical Care Medicine
• Physical Therapy
• Biomedical Engineering

Background:

• Continuous Lateral Rotation Therapy (CLRT) is utilized in intensive care units (ICUs) for early mobilization of mechanically ventilated patients.
• Concerns exist regarding CLRT's sufficiency for capillary reperfusion, potentially leading to tissue damage.

Purpose of the Study:

• To investigate differences in skin interface pressures, skin integrity, and perceived discomfort among three patient positioning scenarios.
• To evaluate the efficacy of CLRT in managing pressure points relevant to patient immobility.

Main Methods:

• A pressure mapping device was integrated with a Hill-Rom Total Care SpOrt bed.
• Ten healthy volunteers participated, experiencing each of the three positioning scenarios for 30 minutes.
• Interface pressures were systematically recorded for each position.

Main Results:

• CLRT alone resulted in significantly lower interface pressures on the ischial tuberosities compared to static wedge positions (p < 0.05).
• Conversely, higher interface pressures were observed on the heels when using CLRT alone (p < 0.05).
• One participant reported discomfort with CLRT; no skin erythema or breakdown was observed.

Conclusions:

• This feasibility study provides preliminary support for CLRT's role in reducing pressure on capillary beds.
• Findings suggest CLRT may contribute to decreased patient discomfort.
• Further investigation is warranted to confirm these benefits in clinical practice.
