Long-term Use of Intrapulmonary Percussive Ventilation for Preventing Hospitalizations Due to Respiratory Decompensation in Children With Multiple Disabilities

Overview

Chronic respiratory failure is the leading cause of morbidity and mortality in children with multiple disabilities. Musculoskeletal disorders, swallowing disorders and ventilatory control abnormalities lead to progressive respiratory impairment, causing episodes of respiratory decompensation (RD). These are the leading cause of mortality (50 to 80%, average age of death: 21 years) and the cause of repeated hospitalizations. Respiratory care for these children is therefore a major challenge. In respiratory physiotherapy, this can be achieved through manual techniques and/or instrumental techniques such as intrapulmonary percussive ventilation (IPV), which is particularly useful in this population because it does not require active cooperation. The main objective of this study is to evaluate, in children with multiple disabilities, the effectiveness at 18 months of using an IPV at home and by carers, combined with standard respiratory physiotherapy, compared with manual respiratory physiotherapy alone.This is a multicenter, randomized controlled superiority trial with two parallel groups. All centers will recruit children aged 1 to 16 with multiple disabilities, during hospitalization with respiratory decompensation (RD). After consent has been signed by the parents or legal guardians, the patient will be randomized into one of the two study groups: * Control group: manual respiratory physiotherapy. * Intervention group: intrapulmonary Percussive Ventilation (IPV)

IPV is used in France in different ways, depending on the center and service practices, as a complement to manual techniques. At Armand Trousseau University Hospital, our experience over the past five years with more than 50 children suggests that the use of IPV by carers in their home environment. This is done as a complement to private manual physiotherapy sessions after training by a professional. However, the benefits and impact of IPV on patients' respiratory development remain largely unstudied, particularly in patients with multiple disabilities. This multicenter randomized controlled study could provide recommendations for the respiratory management of these patients. The main objective of this study is to evaluate, in children with multiple disabilities, the effectiveness at 18 months of using an IPV in the home and by carers, combined with standard respiratory physiotherapy, compared with manual respiratory physiotherapy alone. The primary endpoint is the number of rehospitalizations for RD at 18 months following the index hospitalization. All centers will recruit children aged 1 to 16 with multiple disabilities, during hospitalization with Respiratory Decompensation (RD). the patient will be randomized into one of the two study groups: * Control group: * Intervention group: the use of IPV will be initiated during hospitalization. The total duration of the study is planned to be 36 months, Follow-up visits will be scheduled at 1, 3, 6, 12 and 18 months for both groups. In order to avoid adding too many trips for these families, who are often very busy, visits will be scheduled at the same time as routine medical and paramedical consultations whenever possible. Certain visits that cannot be synchronized with routine follow-up consultations will be conducted via videoconference or telephone calls by the study investigators. An adjudication committee will validate respiratory decompensation following rehospitalization that may occur within 18 months of the child's inclusion/randomization in the PERKINE protocol. They will remain blinded to the child's randomization group until the end of the study. Analysis will be performed at the end of the study after data review and before database lock
