The Effects of Inhalation Aromatherapy on Postoperative Abdominal Pain: A Three-Arm Randomized Controlled Clinical Trial

PurposeThis study compares the effects of inhalation aromatherapy using essential oils of sweet orange and damask rose on postoperative abdominal pain. DesignA randomized three-arm controlled trial. MethodsIn this randomized double-blinded, and parallel-group controlled trial, a total of 120 patients who underwent open abdominal surgeries were enrolled using a sequential sampling method. Participants were then randomly assigned to three groups of sweet orange, damask rose, and placebo (distilled water) using the permuted block randomization. When the patients regained full consciousness, a clean gauze impregnated with four drops of either distilled water or essential oils of sweet orange or damask rose were attached to the collar of the patients, and they were asked to inhale the aroma through normal breathing for 30 minutes. Abdominal pain severity was recorded using the visual analog scale at four time points including before the intervention (baseline) and 4, 8, and 12 hours after the intervention. FindingsPain reduction after sweet orange inhalation was significantly greater than placebo (at 8 and 12 hours after the intervention) and damask rose (at 12 hours after the intervention). The differences in the mean score of pain severity between all before-and-after observations were statistically significant in the three groups, except in the placebo group between the baseline score of pain severity and the pain severity score at 4 hours after the intervention. ConclusionsInhalation aromatherapy using sweet orange seems to be more effective than the damask rose in reducing pain severity after open abdominal surgeries.

IntroductionInhalation aromatherapy may help in controlling nausea, vomiting, and anxiety during autologous hematopoietic stem cell transplantation (AHSCT) by masking the malodor of dimethyl sulfoxide. This study examined the preventative effects of inhalation aromatherapy with orange essential oil on severity of nausea, vomiting episodes, and anxiety during AHSCT. MethodsThis open-label randomized controlled trial was conducted at two stem cell transplantation units in Ankara, Turkey. A total of 70 patients were randomly assigned to either an intervention (n = 35) or a control group (n = 35). Patients in the intervention group inhaled the odor from six drops of pure orange essential oil during AHSCT. Patients in the control group received routine care. Nausea severity was evaluated at baseline and the beginning of each new infusion bag. Number of vomiting and retching episodes was recorded during the AHSCT. Anxiety level was measured just after the completion of AHSCT. ResultsThe nausea severity (p = 0.931; 0.721 and 0.363 for the first, second and third bags, respectively), and the number of retching episodes (p = 0.741 and 0.485 for the first and second bags, respectively) and vomiting episodes (p = 0.396 and 0.957 for the first and second bags, respectively) showed no significant differences between the groups. The mean anxiety score was significantly lower for the intervention group than for the control group (p = 0.007). ConclusionInhalation aromatherapy with orange essential oil may be useful to alleviate anxiety during AHSCT; however, it does not appear to decrease nausea severity, and number of vomiting and retching episodes. Further studies are needed to confirm the study findings.
