Efficacy of Inhaled Aromatherapy on Nausea and Vomiting in Hematological Malignancies

This project will optimise the management of chemotherapy-induced nausea and vomiting, with improvements in nausea and vomiting scores, quality of life and appetite expected in participants benefiting from the intervention. In all cases, the use of complementary methods is recommended and improves the management of people with cancer because they offer a person-centred approach.

The aim is to evaluate the efficacy of inhalation of a mixture of ginger and lemon Essential Oils (EO) versus placebo in addition to conventional antiemetic treatments on the intensity of chemo-induced nausea during the acute phase D1 (H24) of its onset in patients with C1 haematological malignancies. This multicentre study will be carried out in 5 establishments (haematology and oncology care sectors), which represents a very high potential for inclusion. In addition, the investigator expect a very high acceptance rate for this study. In fact, in the context of CINV, this care strategy may meet a patient's expectation of symptoms (nausea, vomiting) that they find difficult to manage. Finally, it is known that patients in these care sectors are very keen on supportive care to improve their quality of life, so this is a potentially very interesting opportunity without any particular risk that is offered to participants in this study. A nurse and a doctor with a postgraduate diploma in aromatherapy are coordinating the team, with the support of a nurse trained in evidence-based practice research methodology. Institutional procedures drawn up by the team at Limoges University Hospital describe the general procedure for using aromatherapy in a scientific and safe way, the protocols that can be used to describe the operating methods, the traceability of the manufacture of the mixtures and their administration, and the evaluation of their effectiveness. Supporting documents, an information note and a monitoring sheet have been created and are being used.
