Abstract

Context: Anxiety is an unpleasant emotion and inhaling Jasmine Essential Oil (JEO) may decrease anxiety before laparotomy.
Aims: Determining effects of inhaling JEO on anxiety and blood cortisol levels in patients undergoing laparotomy.
Setting and Design: The setting was 5th Azar Hospital in Gorgan (Iran) and the study was a single blind parallel, randomized, controlled clinical trial that was conducted in 2016.
Materials and Methods: The subjects (84 patients) were randomly allocated in two intervention and control groups. The intervention and control group inhaled two drops of JEO and two drops of distilled water respectively for 60 min. Blood cortisol and anxiety levels were measured immediately after intervention by ELISA kit, and the Spielberger’s State Anxiety Inventory, respectively.
Statistical Analysis: The data were described with mean, Median, Interquartile Range (IQR) and analyzed using t‑test, Chi‑square, Wilcoxon signed‑rank, Mann–Whitney U and correlation coefficient tests.
Results: The mean score of anxiety in JEO group before and after intervention was 50.90 ± 7.71 and 36.42 ± 6.62 (P = 0.001), respectively and median (IQR) of the cortisol was 160.7 (60.88) and 93.15 (52.38), respectively (P = 0.001). In the control group, cortisol (IQR) level increased (124.1 (67.42) to 127.9 (62.42), P = 0.02) and the mean anxiety score decreased slightly (P = 0.43). Median and IQR of difference cortisol level before and after in the intervention and control group were significant (P = 0.001).
Conclusion: Our findings suggest that aromatherapy with JEO may have beneficial effects on preoperative anxiety in patients undergoing laparotomy.
