Previous studies have shown that signs of drowning in fresh water are of low diagnostic value. Regardless of the mechanism of drowning death, a certain amount of water enters the blood and somehow changes its composition. The objective of this study was to determine water fractions in the blood of drowned subjects. It included 30 cases of drowning deaths. The control group comprised 30 cases of hanging and 7 bodies found in water after the death on land. The water content in the blood was measured in accordance with the universally accepted diagnostic procedure from the difference of freezing temperatures of free and bound water. It was shown that arterial blood and its constituent components as well as whole venous blood and concentrated red cells mass of drowned subjects contained significantly more water than the blood of those who died on land. The rise was in the first place attributable to the selective increase of the free water fraction. Changes of water content in the blood were virtually identical in the drowned subjects who died from asphyxia and from aspiration of water. The data obtained in this study may be used as additional diagnostic signs of drowning death.
先前的研究表明，淡水溺水迹象的诊断价值较低。无论溺水死亡的机制如何，一定量的水会进入血液并以某种方式改变其成分。本研究的目的是确定溺水者血液中的水分含量。该研究包括30例溺水死亡病例。对照组包括30例缢死病例和7例在陆上死亡后在水中发现的尸体。根据普遍接受的诊断程序，通过测量游离水和结合水的冷冻温度差异来测定血液中的含水量。结果表明，溺水者的动脉血及其组成成分、全静脉血和浓缩红细胞团中的含水量明显高于陆上死亡者的血液。这种增加首先归因于游离水含量的选择性增加。因窒息和吸入水而死亡的溺水者血液中的含水量变化几乎相同。本研究获得的数据可作为溺水死亡的额外诊断指标。
