Study Details

Brief summary:

This clinical trial tests how well aromatherapy essential oils work to manage anxiety and nausea in cancer patients receiving infusions in the ambulatory setting. Current drugs that are given for nausea may cause constipation and fatigue. Therefore, there is interest in exploring complementary therapies, like aromatherapy, that do not carry the same side effects. Using aromatherapy essential oils such as ginger, peppermint, and lavender, may help reduce nausea and anxiety. Some studies have shown significant reductions in nausea and anxiety among cancer patients using these oils, while other studies have had mixed results. Ginger and peppermint oils, in particular, have been associated with helping reduce nausea during chemotherapy, while lavender has shown potential benefits for anxiety. Jojoba oil will be used as a placebo for this research study. Jojoba oil is extracted from the seeds of a jojoba plant, which is a green shrub that is found in the southwestern United States). Jojoba oil is an oil which has no color or smell. Aromatherapy essential oils used through a personal inhalation device during chemotherapy may better manage anxiety and nausea in cancer patients receiving infusions in the ambulatory setting.

Interventions and Outcome Measures

Arms

experimental: Arm I (peppermint oil)

Patients inhale peppermint essential oil via the PID once every hour starting on day 1 during their anti-cancer/chemotherapy infusions. Patients continue to inhale the peppermint essential oil via the PID at least three times a day for 4 days.

experimental: Arm II (lavender oil)

Patients inhale lavender essential oil via the PID once every hour starting on day 1 during their anti-cancer/chemotherapy infusions. Patients continue to inhale the lavender essential oil via the PID at least three times a day for 4 days.

experimental: Arm III (ginger oil)

Patients inhale ginger essential oil via the PID once every hour starting on day 1 during their anti-cancer/chemotherapy infusions. Patients continue to inhale the ginger essential oil via the PID at least three times a day for 4 days.

placebo comparator: Arm IV (placebo jojoba oil)

Patients inhale placebo jojoba essential oil via the PID once every hour starting on day 1 during their anti-cancer/chemotherapy infusions. Patients continue to inhale the placebo jojoba essential oil via the PID at least three times a day for 4 days.
