[An autopsy case of accidental hanging during home care]

A 73-year-old man who had suffered from old myocardial and cerebral infarction for 4 years had been secured in wheelchair due to left hemiplegia and aphasia and also been received a home care of his wife. One day, his wife tied a cloth belt around his head and secured it to the wheelchair to prevent the flexion of his neck. One hour later, he was found dead by his wife. He also had slipped down in his wheelchair. The autopsy performed 24 hours after death revealed a ligature marks on the front of the neck. Petechial hemorrhages, visceral congestion and fluid blood, compatible with asphyxial death, were also found. Although severe cerebral cortical atrophy, old myocardial infarction, moderate to severe atherosclerosis and decubitus of the back were also found, they were not considered primary cause of death. No other anatomical or toxicological cause of death was present. Therefore, we concluded that the man died of accidental hanging. Recently, the home care of aged or handicapped patient is a social problem in Japan due to the increase in the number of elderly people. The death was caused by the inappropriate restraints used by his wife. This case suggests the importance of proper advice to non-professional caretakers from care professionals.
