Outline of Final Research Achievements

This study clarified the hardness of mattresses that can effectively prevent pressure ulcers when lying in the prone position. Subsequently, the predictors of skin and soft tissue deformation of this hardness were identified based on external force applied in the prone position and physiological factors.
The hardness of mattresses that can effectively prevent pressure ulcers was 87.5 N and 175 N. The distance between the left and right greater trochanters, maximum interface pressure, and age were the significant predictors of skin and soft tissue compression. Furthermore, the distances between the left and right anterior superior iliac spines and greater trochanters were the significant predictors of internal soft tissue displacement. Meanwhile, no factors predicted skin surface displacement.

Academic Significance and Societal Importance of the Research Achievements

これまで、腹臥位で褥瘡予防に有効な硬さを明らかにした検討はなかった。また、腹臥位で皮膚軟部組織変形の予測因子を特定した検討もなかった。そのため、本研究は新規性がある。
臨床で簡便に使用できるこの皮膚軟部組織変形の予測モデルの活用が期待でき、腹臥位手術の褥瘡予防に貢献できると考える。
