THE CHANGE IN PHYSIOLOGICAL FUNCTION AND SKIN MANIFESTATION OF PERISTOMAL SKIN, CAUSED BY WET-EXPANSION OF SKIN BARRIER ― CAN EXPANSION OF SKIN BARRIER BE USEFUL TO DETERMINE WHEN IT IS NECESSARY TO REAPPLY THE AGENT

Abstract

　To study the wet-expansion of the skin barrier as a criterion for the timing of reapplication of skin barriers,we observed the physiological action of the peristomal skin and monitored its manifestation on 20 patients undergoing stoma rehabilitation.
　Measurements were taken on healthy skin,skin on which skin barrier was dissolved,skin on which the material of skin barrier was wet-expanded,and skin to which tape was adhered.
　When the skin under wet-expanded skin barrier was compared with the skin under the non-expanded skin barrier,there was a significant difference in pH and transepidermal water loss（TEWL）but no significant difference in hydration state.
　The study indicates that the wet-expansion of skin barrier can be useful in determining the time to reapply the skin barriers.
