Summary
Shorter hanging times and the presence of a heartbeat upon arrival significantly improve survival rates in hanging incidents. Glasgow Coma Scale scores on arrival are critical indicators for predicting outcomes.
Area of Science:
- Forensic Medicine
- Emergency Medicine
- Clinical Toxicology
Background:
- Hanging is a significant cause of mortality.
- Understanding factors influencing survival is crucial for medical intervention.
- Prognostic indicators in hanging cases require further elucidation.
Purpose of the Study:
- To identify variable factors affecting outcomes in hanging incidents.
- To determine key prognostic factors for survival after hanging.
Main Methods:
- Retrospective review of 47 patients presenting after hanging.
- Analysis of clinical data including hanging time, vital signs, and Glasgow Coma Scale (GCS) scores.
- Comparison of factors between survivors and non-survivors.
Main Results:
- Mean hanging time was significantly shorter in survivors (11.8 min) versus non-survivors (50.81 min).
- Presence of heartbeat on arrival was observed in 90.9% of survivors, compared to only 5.6% of non-survivors.
- Glasgow Coma Scale (GCS) score on arrival was a significant predictor; patients with GCS > 3 had better outcomes than those with GCS = 3.
Conclusions:
- Hanging time, presence of cardiopulmonary arrest (CPA) on arrival, and GCS on arrival are critical prognostic factors.
- Early recognition of heartbeat and higher GCS scores indicate a better prognosis.
- These factors can guide emergency medical response and resource allocation in hanging cases.
