Comparative Evaluation of Pressure Distribution of Three Support Surfaces Used for Pressure Injury Prevention during Prolonged Surgeries.

Pressure injuries, also known as pressure ulcers, pose a serious health care concern for patients undergoing lengthy surgeries due to prolonged immobility while under anesthesia. The occurrence of pressure injuries can be costly and adversely impact patient outcomes, leading to increased morbidity, extended hospital stays, and a reduced quality of life. One preventative approach is to use engineered support surfaces designed to redistribute pressure, thereby reducing the risk of tissue damage. This study aimed to compare the effectiveness of 3 different support surfaces to redistribute pressure: standard surgical foam, gel overlay, and an active, small-cell alternating-pressure air mattress.
