Anoxic Brain Injury and Mortality in Hanging-Related Trauma

Hanging is a highly lethal method of suicide associated with substantial neurologic morbidity among survivors. Although multiple injuries have been described following near-hanging, factors associated with mortality remain unclear. This study aimed to characterize injury patterns and identify predictors of mortality in hanging-related trauma.MethodsA retrospective cohort study was performed using the TriNetX Research Network. Adult patients (≥18 years) with hanging-related trauma between 2004 and 2024 were identified using ICD-based codes and stratified by in-hospital mortality. Demographics, injury patterns, and outcomes were compared between survivors and non-survivors.ResultsA total of 3748 patients met inclusion criteria, including 3167 survivors (84.5%) and 581 non-survivors (15.5%). Mean age was 31.1 ± 14.3 years, and 68% were male. Anoxic brain injury and cerebral edema were significantly more common among non-survivors than survivors (34.0% vs 11.6%,
