Summary
Intoxicated pedestrians involved in motor-vehicle accidents sustain more severe injuries and have higher mortality rates. These victims are typically younger males, often struck during evening hours.
Area of Science:
- Trauma Surgery
- Forensic Pathology
- Public Health
Background:
- Pedestrian accidents are a significant cause of motor-vehicle fatalities, with high morbidity and mortality.
- Classic injury patterns exist, but the impact of pedestrian intoxication remains unclear.
- Understanding intoxication's role is crucial for targeted prevention and treatment strategies.
Purpose of the Study:
- To delineate the injury patterns and outcomes of intoxicated versus non-intoxicated pedestrian victims.
- To compare demographic, injury, and survival data between the two groups.
Main Methods:
- Retrospective autopsy review of 223 pedestrian fatalities.
- Victims categorized into alcohol-positive (Group II) and alcohol-negative (Group I) groups.
- Analysis of demographics, injury types, survival time, and accident circumstances.
Main Results:
- Intoxicated victims (Group II) were more frequently young males (79%) compared to Group I (64%).
- Group II had significantly more severe injuries, including cervical spine (2x), liver (2x), extremities (2x), pelvis (2x), ribs (2x), thoracolumbar spine (2x), aorta (3x), and heart (5x).
- Mortality within 24 hours was higher in Group II (95%) than Group I (67%); accidents often occurred between 1500h and 2300h.
Conclusions:
- Intoxicated pedestrian victims are predominantly young males.
- They exhibit a significantly more severe injury profile, with increased rates of critical organ and skeletal trauma.
- Intoxication is associated with a more rapidly fatal outcome in pedestrian traffic accidents.
