Autopsied cases of drowning in Denmark 1987-1989

In the 3-year period 1987-1989, 219 drowning cases were submitted to medico-legal autopsy in Denmark. The demographic data including the manner of death and the external findings are reported. In 74 accident cases analysis for blood-alcohol concentration was performed. In 53% a concentration of more than 0.1% was found. In 91 drowning cases (age more than 18 years and where the time interval in the water was less than 24 h) the average weight of both lungs was 1.411 g, compared to 994 g in 20 control cases. In 7% of the drowning cases the weight was less than 1.000 g, so called dry lungs. Finally the weight of the lungs and the amount of pleural transsudate in relation to the time interval in the water were registered in 198 cases. For a longer time interval in the water the weight of the lungs decreased, while the amount of pleural transsudate increased. By adding these two parameters, the combined weight was between 1.000 and 2.200 g in more than 75% of the cases as long as the interval in the water was less than 30 days.
