高齢者への医療用粘着テープの剝離方法に関する研究—皮膚への影響に対する剝離角度の検討

Effects of Angle of Peel on Medical Adhesive Tape Removal in Elderly Skin

　医療用粘着テープの皮膚刺激の少ない剝離方法を明らかにすることを目的に，高齢女性10名を対象に，剝離角度による皮膚刺激を比較した．剝離角度は，30°，60°，90°，120°，150°，180°を設定し，評価項目は，剝離力，角質細胞剝離量，剝離後の発赤消退時間，剝離時の痛みとした．

　角質細胞剝離量は剝離角度間で有意な差は認められなかった．剝離角度30°と60°は，90°以上に比べて有意に剝離力が大きかった．剝離角度30°は，90°以上より有意に発赤消退時間が長く，剝離時の痛みが強かった．

　これらから，剝離角度90°以上での剝離が望ましいことが示唆された．

　This study investigated the effects of angle of peel when removing medical tape from the skin of elderly women. In 10 subjects, 8 segments of acrylic adhesive tape were placed on the bilateral thighs and peeled off 24 hours later at 6 angles of peel(30°, 60°, 90°, 120°, 150°, 180°). The data consisted of the amounts of stratum corneum stripped, the peel force, the time required for redness to fade and the feeling of irritation.

　The amounts of stratum corneum stripped did not significantly differ among the 6 angles of peel. The peel force required to strip the adhesive tape at 30° and 60° was significantly more than that required to strip the tape other peel angles. The time required for redness to fade after tape stripping at a peel angle of 30° was significantly longer than the times required at 90°, 120°, 150°, and 180°. Concerning the feeling of irritation during the tape stripping, that produced at 30° was significantly worse than the irritation produced at 90°, 120°, 150°, or 180°.

　These findings suggest that a peel angle greater than 90° causes less skin irritation.
