Abstract

Introduction: Poor sleep quality is prevalent in candidates for percutaneous coronary interventions (PCIs). The present study was conducted to compare aromatherapy with acupressure in terms of their effectiveness in sleep quality in patients undergoing PCIs.

Materials and methods: The present study was conducted on 85 patients undergoing PCIs and randomly assigned, using block randomization, to five groups, namely (1)aromatherapy, (2)placebo aromatherapy, (3)acupressure, (4)placebo acupressure (acupressure applied to a point not traditionally associated with improving sleep) and (5)control. The intervention groups received aromatherapy or acupressure or placebo from 10pm to 8am the following day. The control group received only routine care. Sleep quality was measured in the patients using a visual analog scale (VAS) that was completed by them before and after the intervention.

Results: The mean pretest score of sleep quality was 2.91 ± 0.53 in the aromatherapy group, 2.84 ± 0.47 in the placebo aromatherapy group, 2.98 ± 0.59 in the acupressure group, 2.75 ± 0.41 in the placebo acupressure group and 2.88 ± 0.41 in the controls. ANOVA suggested no significant differences among these groups in the pretest (P = 0.746). The mean posttest score of sleep quality was 3.72 ± 1.84 in the aromatherapy group, 3.70 ± 1.83 in the placebo aromatherapy group, 7.35 ± 0.99 in the acupressure group, 2.67 ± 0.41in the placebo acupressure group and 2.72 ± 0.34 in the controls, suggesting significant differences among the five groups based on the ANOVA results showed significant differences among the five groups (P < 0.001). The mean posttest score of sleep quality was higher than the pretest score by 4.37 in the acupressure group compared to in the other groups (P < 0.001).

Conclusion: The present findings provided scientific evidence for the benefits of using different methods, including acupressure, for sleep quality in patients undergoing PCIs.
