Aromatherapy inhaler to reduce distress after a hematopoietic stem cell transplant

Aromatherapy Inhaler Use for Hematopoietic Stem Cell Transplant Patient Distress

Not applicable Interventional Stanford University · NCT05302583

We will test whether using a lavender or peppermint aromatherapy inhaler in the first days after a hematopoietic stem cell transplant helps reduce cancer-related distress and improve coping.

What this trial studies

This interventional study provides HSCT patients with a lavender or peppermint aromatherapy inhaler on a single post-transplant day and compares distress and coping to a standard-of-care washout day. The protocol includes an initial aromatherapy day (post-transplant day +1 to +3), a washout day with only standard pharmacologic care, and a follow-up phase day (post-transplant day +3 to +5), with activities occurring on one day per phase. A three-day window for the aromatherapy phases accommodates patients' variable recovery in the immediate post-transplant period. Outcomes focus on short-term changes in distress and coping during the early post-transplant course.

Who should consider this trial

Good fit: Adults over 18 with hematologic malignancies undergoing planned autologous or allogeneic HSCT at Stanford who can consent and are not allergic to lavender or peppermint are the intended participants.

Not a fit: Patients allergic to lavender or peppermint, those receiving CAR T-cell therapy, those transplanted for germ cell tumors, or patients with atrial fibrillation, scleroderma, or G6PD deficiency are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If effective, aromatherapy inhalers could provide a low-risk, nonpharmacologic option to reduce short-term distress and support coping after HSCT.

How similar studies have performed: Prior small trials of inhaled aromatherapy in cancer and perioperative contexts have shown modest reductions in anxiety and distress, but overall evidence is limited and mixed.
