The main objective of this prospective transversal comparative study is to describe the quality of life of children supported by ECMO. These patients are described in detail at the Nantes University Hospital, in particular the elements of neurological monitoring. These results will be analyzed in reference to a population hospitalized at the same age, in the same period, and sharing the same diagnostic categories.

Inclusion Criteria:

• Patients accepted in pediatric intensive care at the Nantes University Hospital between January 2014 and December 2022
• Patients less than 10 years old at admission to the intensive care unit,
• Patients older than 2 years at the time of the cross-sectional evaluation
• For the ECMO group: Patients supported by ECMO
• For the control group: Patient intubated-ventilated for more than 48 hours and/or having received amines and/or having received organ support other than ECMO.
• Patient affiliated to the Social Security.
• Patient with parents who do not object to the study

Exclusion Criteria:

• Known genetic pathology or malformative association at the time of admission to the intensive care unit that could lead to severe neurodevelopmental deficits, independently of the medical events that resulted in the admission to the intensive care unit
• Language difficulty that does not allow for complete information and questionnaire collection

The patients included (ECMO group) will be patients under 10 years of age treated by ECMO at the University Hospital of Nantes from January 2014 to December 2022 and who have reached the age of 2 years during the study (the hetero-evaluation questionnaires for the primary endpoint being validated from this age).

The controls will be patients hospitalized at the same age in pediatric intensive care and at the same periods, who have been intubated and ventilated for at least 48 hours, and/or who have received amines and/or who have benefited from organ support other than ECMO (CONTROL group).
