Do we need neuroimaging in every case of near-hanging?: experience from a level 1 trauma center and analysis of the National Trauma Data Bank

Our study analyzes imaging results in near-hanging to determine what neuroimaging workup is necessary. We evaluate GCS as a clinical predictor to help guide imaging choice. This is a retrospective study of patients from a level one trauma center and from the National Trauma Data Bank (NTDB). We classified injuries into categories based on the likelihood that CT played an important role in their diagnosis and management. We assessed whether a normal Glasgow Coma Scale (GCS) could exclude clinically important injuries. Chi square was used to test for significance for categorical variables. Multivariate logistic regression was used for multivariate analysis. CT showed structural brain findings in 0% of patients from our facility (local patients) and 11.7% of NTDB patients. Of local patients and NTDB patients, 1.4% and 6.6% had blunt cerebral vascular injury (BCVI) respectively. Of local patients and NTDB patients, 1.4% and 3.3% had a cervical spine fracture or dislocation, respectively. Mortality for patients with GCS 15 versus GCS
