Outline of Final Research Achievements

Mucin is one of the most useful substances for the prevention and control of bedsores because of its in vivo lubricating ability. In this study, the frictional properties of mucin suspension between nursing clothes and artificial skin were investigated.The results suggest that the concentration range of mucin suspension that contributes to friction reduction is 300-400 [g/L], and that the coefficient of static/dynamic friction changes with concentration of mucin suspension are related to the cohesive property of mucin. Furthermore, the effect of repeated washing was also found to be effective. Although the mucin suspension had no antimicrobial properties, it was found that the addition of an antimicrobial substance (boric acid) did not change the friction-reducing effect.

Academic Significance and Societal Importance of the Research Achievements

高齢化社会を迎える日本にあって、床ずれの抑制・予防策は重要な課題である。床ずれは寝たきり状態でなくても非常に起こしやすい疾患でありながら、まだ抑制・予防策についての検討は十分ではない。本研究で得られた結果は、介護服に抗菌性物質を含んだムチン懸濁液を塗布するだけで(患者への負担もほぼ無く)、床ずれの抑制・予防策となりえる。その結果、入院期間の短縮が見込まれ、高齢者の早期社会復帰(QOL向上)に大きく貢献できる。
