Abstract
BackgroundSeverely ill patients often experience problems with sleep. Either acupressure or valerian aromatherapy are reported as helpful in promoting sleep. ObjectivesThe purpose of this study was to explore the effectiveness of valerian acupressure on the sleep of patients in the intensive care unit (ICU). DesignA randomized clinical trial. SettingA 42-bed adult intensive care unit. ParticipantsForty-one subjects in the experimental group and 44 subjects in the control group. MethodsThe measurement included observation, and actigraphy measures during 10pm–6am, and the Stanford Sleepiness Scale (SSS) measures on the next morning. Experimental groups received valerian acupressure on the Shenmen, Neiguan, and Yongquan acupoints between 7pm and 10pm of the second day while control groups received regular treatment. Heart rate was measured for 5min before and after valerian acupressure present for HR variability analysis to measure relaxation response. ResultsThe results indicated that after receiving valerian acupressure, patients’ sleeping hours increased, wake frequency reduced and SSS grades declined. The HR variability data indicated relaxation response immediately after valerian acupressure. ConclusionThis study supports the hypothesis that valerian acupressure on the Shenmen, Neiguan, and Yongquan acupoints could improve the sleeping time and quality of ICU patients.
