| Abstract: | ObjectiveThe purpose of this study was to compare the aromatherapy treatment effects on PONV patients using ginger, lavender and rose oils and a placebo.DesignA randomized 4-armed placebo controlled study.SettingGaziosmanpasa University, School of Medicine, Health Research and Application Center.InterventionThe total of 184 patients were randomized into 4 groups: Aromatherapy with lavender essential oil (Lavender group), with rose essential oil (Rose group), with ginger essential oil (Ginger group) or with pure water (Placebo group).Main outcome measuresPostoperative nausea (0–3 Likert type; 0=no nausea, 1=some, 2=a lot, 3=severe) and vomiting scores (0–3 Likert type; 0=no vomiting, 1 = 1 time, 2 = 2 or 3 time, 3 = 4 times and up) and antiemetic medication requirement.ResultsThe nausea scores at 15 min were statistically significantly different between the groups (p = 0.00). The postoperative nausea scores improved in 20 (43.5%) subjects in the placebo group, 38 (82.6%) subjects in the lavender group, 22 (47.8%) subjects in the rose group and 30 (65.2%) subjects in the ginger group (p = 0.00). There were statistically significant differences between the groups with regard to the vomiting and antiemetic drug requirements (p = 0.00).ConclusionThe aromatherapy can be used as an alternative or complementary method for managing PONV. Specifically, the ginger and lavender essential oils were superior to the rose oil and pure water for the aromatherapy treatments. However, further studies with larger sample sizes are necessary to confirm these results. |
