Insights
Nontraumatic prehospital sudden death (NPSD) causes vary by age, with coronary artery disease prevalent in older adults and non-CAD cardiac disease or toxic ingestions in younger individuals. Abdominal hemorrhage was a fatal subgroup.
Area of Science:
- Cardiology
- Emergency Medicine
- Forensic Pathology
Background:
- Nontraumatic prehospital sudden death (NPSD) presents diverse etiological profiles.
- Understanding age-specific causes is crucial for targeted interventions.
- Identifying prognostic factors aids in resuscitation strategies.
Purpose of the Study:
- To analyze the causes and outcomes of NPSD in adults.
- To determine age-specific etiological patterns.
- To evaluate prognostic variables in NPSD.
Main Methods:
- Retrospective review of clinical and autopsy records for 83 NPSD cases.
- Categorization of deaths by age groups and primary causes.
- Analysis of emergency room presentation rhythms and survival rates.
Main Results:
- Coronary artery disease (CAD) was the leading cause in 36-45 year olds; non-CAD cardiac disease was second.
- In 18-35 year olds, non-CAD cardiac disease and toxic ingestions were primary and secondary causes, respectively.
- Survival was linked to non-asystolic rhythms; toxic ingestions had better resuscitation prognosis.
- Abdominal hemorrhage (8/83 cases) was uniformly fatal, suggesting a distinct subgroup.
Conclusions:
- NPSD etiology differs significantly between younger (18-35) and older (36-45) adults.
- Early detection and intervention for abdominal hemorrhage are critical.
- Rhythm at emergency room presentation and toxic ingestions are key prognostic indicators.
Abstract:
The clinical and/or autopsy records of 83 consecutive adults presenting with nontraumatic prehospital sudden death (NPSD) in a single county were reviewed. Coronary artery disease (CAD) was the primary cause of death in individuals 36 to 45 years old. Non-CAD cardiac disease was the second most common cause of NPSD in this age group. Between the ages of 18 and 35 years, non-CAD cardiac disease was the primary cause and toxic ingestions were the second most common. Patients with rhythms other than ventricular fibrillation/tachycardia, asystole, or electromechanical dissociation on presentation to the emergency room (ER) were more likely to survive. Patients with asystole in the ER were more likely to die in the ER than were patients with other rhythms. Patients with toxic ingestions tended to have a better prognosis for successful resuscitation and for ultimate survival. Age, sex, bystander cardiopulmonary resuscitation, and time in the field were not significant prognostic variables. Patients with abdominal hemorrhage (eight of 83) as the cause of NPSD may represent a subgroup for whom a special approach is warranted. None of these patients survived. Early detection by culdocentesis or paracentesis in female patients of reproductive age and nasogastric lavage or stool occult blood testing could lead to more vigorous fluid resuscitation and early surgical intervention in abdominal hemorrhage.
