Cases of asphyxia in children and adolescents: a retrospective analysis of fatal accidents, suicides, and homicides from 1998 to 2017 in Hamburg, Germany

Abstract

Purpose Injury-related asphyxia is one of the most common causes of death in children in Germany. However, only a few systematic studies have analyzed the causes and circumstances of asphyxia in children and adolescents. Methods All cases of asphyxia in children and adolescents (0-21 years of age) among the Hamburg Legal Medical Department's autopsy cases from 1998 to 2017 were retrospectively analyzed with special focus on how often external findings were completely absent. Results Among 249 cases of fatal asphyxia, 68% were accidents, 14% were suicides, and 13% were homicides. Most of the cases involved boys. Adolescents and young adults aged 15-21 years represented the main age group. Drowning was the leading mechanism of asphyxia. Younger age was associated with less frequent detection of external signs of asphyxia in the postmortem external examination. Petechial hemorrhages were the most common visible external indication of asphyxia. No external findings indicative of asphyxia were present in 14% of the cases. Conclusion Asphyxia in children and adolescents often involves accidents. However, postmortem external examination alone is insufficient to identify asphyxia and the manner of death.

Trends of Asphyxial Deaths and Its Association With Various Demographic Factors Reported to Forensic Medicine Department Peshawar; An Autopsy-Based Retrospective Study

“…These deaths are typically confirmed through autopsy-based studies, providing valuable insights into the patterns and demographics of such fatalities. Notably, a consistent male-to-female ratio of 2:1 is observed across various regions, including Brazil 12 , Germany 13 , and South Asian countries like Pakistan (14) and India. 15 The higher frequency of asphyxial deaths among males can be attributed to societal roles, where males often serve as the primary breadwinners of their families.…”

Mortality in Cases of Acute Alcohol Intoxication in Children

“…In the age groups less than 10 years, minimal numbers of cases were observed. 16,19 We also registered minimal numbers of cases with alcohol intoxication at these ages.…”

A safe procedure? The unusual case of a fatal airway obstruction by silicone during the production process of a tracheostomal epithesis in a 13-year-old boy

“…Asphyxia in children and adolescents often involves accidents [ 7 ]. After comprehensive investigations, the present case of asphyxia due to airway obstruction with silicone impression material in a 13-year-old boy was considered an accident as well.…”
