The purpose of this study was to assess and identify the effects of lavender and neololi oil inhalation on non-sedation gastroscopy subjects on anxiety and stress, physiological variables, objective stress, autonomic nervous system activity, and blood pressure
A quasi-experimental research with nonequivalent control group pretest-post test design was conducted. The subjects of this study were those who were able to communicate and agreed to the study themselves, and gastroscopy examiners who were subjects of national cancer screening at the Health Examination Center of H University Hospital in K city. In order to figure out the effect of aroma inhalation, the experimental group was inhaled with oil blended 1:1 with 100% lavender and 100% Neroli oil, and the control group was inhaled with artificial fragrance. The anxiety using the questionnaire and subjective stress through the VAS was measured before and after gastroscopy, and objective stress, autonomic nervous system activity, and variations in blood pressure using the Canopy9 RSA device were measured before the gastroscopy, upon entry into the endoscopic esophagus, and after the gastroscopy.
The collected data was analyzed using the SPSS win 24.0 program. Anxiety and VAS analysis before and after intervention between the experimental group and the control group were analyzed by t-test. The difference in autonomic nervous system activity and blood pressure between the experimental group and the control group was analyzed by a repeated ANOVA teat.
The conclusions of the analysis are as follows.
Firstly, the score of anxiety of the experimental group inhaled with aroma oil was significantly lower than that the control group (t=3.87 p=〈.001).
Secondly, the psychological stress score device were significantly lower than those in the control group(t=0.94, p=.029).
Thirdly, the objective stress score using the Canopy9 RSA device were significantly lower than those in the control group(F=8.34, p=.005).
Fourthly, the sympathetic nervous system activity score of the experimental group inhaled with aroma oil was not significantly different from the control group (F=0.92, p=.400), and the parasympathetic nervous system activity score was not significantly different between the two groups (F=1.12, p=.054).
Fifthly, systolic blood pressure was significantly lower than the control group in the experimental group (F=6.48, p=.033), but there was no significant difference (F=3.09, p=.053) between the two groups in the case of diastolic blood pressure.
Aromatherapy interventions were most likely to be inhaled multiple times in hospitalized subjects, but in this study, the effect was expected and applied to reduce anxiety and stress with only one inhalation for subjects undergoing tests through the one day visit.
Based on these results, we hope to contribute to reducing the work load of nurses in situations such as delays in examinations and inconsistency in the examination process due to anxiety and stress of the candidates before the examination. In addition, it suggests a repetitive study to provide a basis for the effect of aroma oil inhalation by expanding it to a variety of subjects undergoing the one day procedures and tests that perform invasive tests.
