The Effects of Inhaling Lavender Fragrance on Hemodynamic Indexes during Sheath Take out in Patients after Coronary Angiography in a Military Hospital

Angiography is a detailed and useful method in the diagnosis and treatment of coronary artery disease. One of the steps of angiography is taking out of sheath. This aggressive procedure causes anxiety in many patients. Therefore, hemodynamic indexes (heart rate, blood pressure and respiratory rate) may change.
This study aimed to evaluate the effects of inhaling lavender essential oil on hemodynamic indexes during taking out a sheath in patients after coronary angiography.
This was a quasi-experimental study. Seventy patients undergoing angiography referred to a military hospital in Tehran, Iran were recruited with convenience sampling method during 2015-2016. Then, patients were randomly assigned into intervention and control groups. The intervention group inhaled lavender essential oil during sheath take out and in the control group the placebo of lavender extract inhalation was used. Hemodynamic indexes of patients were measured before, during, 10 minutes and 20 minutes after the aromatherapy. Data were analyzed using chi-squared test, Fisher›s exact test and ANOVA with SPSS software (version 21).
After the intervention, there was a statistical difference in means of respiratory rate (P Discussion and The use of inhaled lavender extract during sheath take out in patients after coronary angiography can reduce hemodynamic indexes. Further studies with high sample size is recommended.
