Abstract

Objectives: The aim of this study was to investigate the effects of patchouli (Pogostemon cablin Benth.)

inhalation by emergency nurses on their stress, compassion satisfaction, compassion fatigue, burnout, blood

pressure, and heart rate.

Design: A randomized controlled trial.

Setting/location: University hospital in Incheon.

Subjects: This study was performed from May to August 2018 after all subjects provided written informed

consent. Fifty eligible emergency nurses were recruited and randomly allocated to inhale 5% patchouli oil in

sweet almond oil (patchouli group, n = 25) or pure sweet almond oil (control group, n = 25).

Interventions: Nurses in the patchouli group first inhaled patchouli oil at about 10 pm (the end of an afternoon

shift) and inhaled patchouli oil a second time at about 10 pm on next day (24-h interval). Nurses in the control

group inhaled pure sweet almond oil following the same schedule.

Outcome measures: Outcome measured included blood pressure, heart rate, levels of stress, compassion

satisfaction, compassion fatigue, and burnout.

Results: Although there were no significant differences in blood pressure, heart rate, compassion fatigue, and

burnout, levels of stress were significantly lower (0.06 – 0.48 vs. 1.19 – 1.19, p < 0.001) and compassion sat-

isfaction significantly higher (0.56 – 2.50 vs. -2.84 – 2.43, p < 0.001) in the patchouli than in the control group.

In addition, relative to baseline, compassion fatigue was significantly lower in the patchouli group (26.72 – 4.98

vs. 25.88 – 4.63, p = 0.016).

Conclusions: Inhalation of patchouli oil effectively reduced the levels of stress and increased compassion

satisfaction in emergency nurses, suggesting that patchouli oil inhalation may improve the professional quality

of life of emergency nurses. ClinicalTrials.gov ID: KCT0004615.
