Inhaled Lavender Effect on Anxiety and Pain Caused From Intrauterine Device Insertion

Intrauterine device (IUD) is the most common reliable, effective and reversible contraceptive method used worldwide and in areas with high growth rate is of particular importance. IUD insertion is associated with high anxiety in most people that causes pain and discomfort. The aim of this study was to determine the effects of aromatherapy on anxiety and pain caused by IUD insertion. This study was conducted on 106 women in a health care center located in Ardebil, Iran. Participants were divided into two groups by randomized blocks of 4 and 6. In the experimental group lavender scent was inhaled and in the control group the placebo was inhaled 30 minutes before IUD insertion. The anxiety of the participants was measured by Spielberger questionnaire, and the pain of IUD insertion was measured immediately after the insertion using visual analog scale (range 0-10). The mean score (standard deviation) of anxiety before intervention was 43.2 (9.2) in the experimental group that decreased after intervention to 39.0 (10.5) (p < 0.001), while this score was 42.2 (9.0) and 41.5 (8.4) before and after the intervention in the control group (p = 0.21). Mean differences of anxiety in both groups was statistically significant (p < 0.001). The pain score after intervention did not show significant difference between two groups (p = 0.51). Aromatherapy with lavender inhalation was effective in decreasing anxiety in IUD procedure, and this method can be used in health care centers as complementary treatments.
