Re-evaluation of death by asphyxia based on cerebral blood flow (VII)--on the information on electric potentials obtained from deep electroencephalographic electrodes.

The author presents electroencephalographic patterns (a physiological parameter of the brain function observed at rapid and fatal drowning of rabbits), cerebral blood flow (CBF) which support the physiological activities of the brain, and the relationship between systemic respiration and circulation with special reference to changes in the electrical potentials detected by deep electroencephalographic electrodes. The possibility of diagnosis of fatal drowning is examined, based on the results.

Action Potentials

Cerebral blood flow and serum haptoglobin in the diagnosis of death by rapid drowning.

Diagnosis of death and the feasibility of resuscitation in cases of acute drowning in fresh water (FW) or sea water (SW) inhalation in rabbits were evaluated using cardiopulmonary function monitoring, measurement of cerebral blood flow (CBF) and determination of haptoglobin (HP). Death took place more quickly in FW drowning, two to five minutes, as compared with four to seven minutes required in SW drowning. In view of the CBF patterns in the brain circulation, many problems exist regarding the judgement of the point of death and the applicability of resuscitation. However, it is considered that brain damage in SW drowning occurs more rapidly than in FW drowning.
