Chizuru Harada 体位変換は,褥瘡予防を目的とし,時間ごとに実施される.その間の背部挙上背臥 位における同一体位持続の苦痛については明らかにされていない.そこで,本研究では 背部挙上背臥位の経時的な苦痛について明らかにすることを目的とした.被験者は,健 康な成人男女 32 名とし,ં度コントロール群を含む背部挙上角度 30 度,45 度,60 度の આ 群に無作為に割り付け背臥位を持続し,120 分まで主観的側面を Visual Analog Scale(VAS)と身体症状の訴え,客観的側面を身体位置の移動距離,LF/HF,体圧, 筋活動について測定した.その結果,VAS,身体位置の移動距離,LF/HF,体圧,筋活 動は時間に有意に影響を受けていた.よって,背部挙上背臥位における同一体位を時 間持続することにより,時間とともに苦痛は増し,姿勢は崩れ,交感神経活動が亢進す ることで,安楽とはいえない状態にあることが示唆された. キーワード:背部挙上背臥位,安楽,苦痛 Patients have their body position changed every two

... rs to prevent bedsores. Much remains unclear about the pain patients endure when they maintain reclining position with dorsal elevation. Therefore, in this study, we aimed to clarify time-dependent pain experienced by patients in reclining position with dorsal elevation. The subjects were 32 healthy adult male and female volunteers assigned randomly to 4 groups of dorsal elevation angle:0°(control) , 30°, 45°, and 60°. While maintaining a reclining position, they were measured in terms of subjective aspects(visual analog scale(VAS)scores, complaints of physical symptoms )and objective aspects( changes in body position, LF/HF ratio, body pressure, and muscular activity)for 120 min. We found that the VAS score significantly increased over time. Changes in body position, LF/HF ratio, body pressure, and muscular activity were significantly affected by time. Our findings suggest that maintaining a consistent reclining position with dorsal elevation for two hours is not comfortable, because over time pain increases, posture deteriorates, and sympathetic nervous system activity rises.
