Background:
Continuous Lateral Rotation Therapy (CLRT) is a therapy used in ICUs for early mobilization of ventilated patients. CLRT is believed by some in health care to not be sufficient to allow for capillary re-perfusion, and may lead to tissue damage.
Objectives:
To determine if there are differences in skin interface pressures, skin integrity, or perceived discomfort across three positioning scenarios.
Methods:
A Hill-Rom Total Care SpOrt(®) bed was equipped with a pressure mapping device. Ten healthy volunteers were placed in each positioning scenario for 30 minutes; interface pressures were recorded.
Results:
CLRT alone demonstrated statistically lower interface pressures on ischial tuberosities (p < 0.05) as compared to the scenarios with static wedge. Higher pressures were noted on the heels in CLRT alone (p < 0.05). One subject noted pain with CLRT. No erythema or breakdown noted.
Conclusions:
This feasibility study supports the use of CLRT to decrease pressure on capillary beds and decrease patient discomfort.
