    In addition to standard intensive care management, patients will receive a hyperbaric oxygen therapy session within eight hours of admission to intensive care (the hyperbaric oxygen therapy session lasts two hours and must be completed eight hours after the hanging attempt).

Study Details

During an attempted hanging, patients present severe neurological distress that can lead to major neuropsychiatric sequelae. These sequelae are notably due to significant cerebral edema related to hanging. Hyperbaric Oxygen therapy is known to reduce cerebral edema and improve cerebral perfusion. The main objective of the study is to evaluate in patients who have attempted hanging without presenting cardio-respiratory arrest, the effect of one Hyperbaric Oxygen therapy session in addition to standard intensive care management on a potential reduction in short-term neurological sequelae. Patients will benefit from either standard management or standard management associated with one Hyperbaric Oxygen therapy session
