Effects of lavender oil intervention before endoscopic retrograde cholangiopancreatography on patients' vital signs, pain and anxiety: A randomized controlled study

Background: This study was carried out to determine the effects of lavender oil intervention before endoscopic retrograde cholangiopancreatography (ERCP) on patients' vital signs, pain and anxiety. Materials and methods: This study was designed as a randomized controlled study. The population of the study consisted of adult patients who were going to receive ERCP at the gastroenterology clinic of a university hospital. Ninety patients participated in the study. The data were collected using a Patient Information Form, a Pre-Post Test Record Form, VAS and the State Anxiety Scale. Results: After lavender oil intervention, the pulse rate, systolic-diastolic blood pressure, pain and anxiety levels of the patients in the experiment group were reduced, their oxygen saturation levels were increased, and the difference between the groups was statistically significant (p < 0.05). Conclusion: Lavender oil applied on the patients before the ERCP procedure reduced their pulse rate, systolic-diastolic blood pressure, pain and anxiety levels, while it increased their oxygen saturation levels.
