[Difficulty to diagnose the cause of death in emergency room].

We evaluated the diagnoses noted on the medical records of 275 patients admitted to Saga Medical College Hospital during the six-year period 1990-1995: 245 patients with cardiopulmonary arrest on arrival (CPAOA) and 30 patients with cardiopulmonary arrest occurring in the emergency room (CPAER). The most frequent cause of CPAOA was heart disease, and the next frequent cause was respiratory disease. In the CPAER patients, the most frequent cause was heart disease, while the next frequent was acute aortic dissection. There were discrepancies in the respective causes of cardiac arrest between the CPAOA and CPAER patients, which was probably due to difficulty in diagnosis in the emergency room. In the emergency room, the cardiopulmonary resuscitation is the first treatment to be performed for CPAOA, the examination for the cause of cardiac arrest is the next followed after the heart beating. However, the cause of cardiac arrest can not be diagnosed in the emergency room for the CPAOA patients without the successful resuscitation, because the examinations for the cause of cardiac arrest can not be performed for the patients without beating heart in the emergency room. Therefore, it is concluded that there exists a need to improve the training for finding out the abnormal death with the inspection and the medico-legal autopsy. It may be suggested that the training system of forensic medicine is ideal for clinical physician who can study the decision of the diseases ranging from toxicosis to acute cardiopulmonary arrest in both the emergency and the forensic medicine.
