1At the Carilion Clinic in Roanoke, Va., Sandra Hubbard is an RN, Kalyn O'Conner is an NP, Ellen Rachel Lockhart is a biostatistician, Kimberly Carter is a Magnet consultant, and Ellen Harvey is a clinical nurse specialist.
Purpose:
The purpose of this study was to examine the effect of aromatherapy with an essential oil blend containing lavender, bergamot, ylang-ylang, and sweet orange, compared with placebo, on perceptions of anxiety in ICU RNs.
Methods:
Nurses recruited from six adult ICUs and a neonatal ICU participated in this blinded, randomized, placebo-controlled study, which took place over a 30-day intervention period.
Results:
Although there were no statistically significant changes in anxiety pre- to postintervention or between the intervention and placebo groups, there were also no adverse events or untoward effects.
Conclusion:
The results of this study may support aromatherapy as an evidence-based strategy to reduce anxiety in ICU nurses. Additional research is needed.
