Caloric intake is a determining factor in patients with hematological malignancies and hospitalized for prolonged aplasia following chemotherapy. The nutritional supplement is administered either parenterally or enterally through the placement of a nasogastric sonde (NGS). This last option has shown its advantage compared to parenteral nutrition in terms of preventing infections, the incidence of graft-versus-host disease in allograft patients, and the quality of resumption of oral nutrition during of returning home. NGS allows the administration of an intake of 2000 calories/day, deemed necessary to mitigate the risk of undernutrition in patients hospitalized for more than 3 weeks and in the majority of cases unable to eat enough food mainly due to chemotherapy-induced mucositis. . The choice between enteral feeding by NGS and parenteral nutrition is the subject of controversial studies, with each team choosing one of the two options. The installation of the NGS is often recognized as a traumatic gesture for patients but also invasive by caregivers. The patient's anxiety, the intrusive and traumatic nature of the NGS can sometimes result in a failure of the gesture, a secondary refusal of the patient, or a reluctance of the caregiver to proceed with the gesture. Since 2013, NGS have been placed with the assistance of the nurse who practices hypnosis in the hematology department of the Rennes University Hospital. This invites the patient to pose his SNG without local anesthesia and in a completely autonomous way. The patient is thus able to place the NGS again if necessary during his hospitalization, and during subsequent hospitalizations. A retrospective and monocentric study carried out at the University Hospital of Rennes in 38 patients showed that all were able to perform NGS independently thanks to the hypnotic approach. It was observed a real comfort for the patient, and moreover this technique did not add extra work for the staff. The patient becomes autonomous and actor of his care.
