Peak serum concentration of creatine kinase as well as the number of injured extremities serve to estimate the severity of crush syndrome.

Crush syndrome and injuries to vital organs were potentially life-threatening. We believe that early transportation of such patients to undamaged hospitals with the ability to provide intensive care would have improved the survival rate.

Changes in clinical pathology parameters, particularly those related to blood coagulation, were examined throughout the gestation period in New Zealand White rabbits. As compared with the non-pregnant group, the following major changes were observed in the pregnant group. For blood coagulation-related parameters, platelets increased progressively and fibrinogen increased slightly from organogenesis, prothrombin time was significantly prolonged during organogenesis and shortened in the late fetal growth stage, activated partial thromboplastin time was significantly prolonged during the fetal growth stage, and antithrombin III increased during and after late organogenesis. Such changes in blood coagulation-related parameters during the later stages of gestation seem to be physiological responses in preparation for protecting against excessive haemorrhage or haemostasis at parturition. For the other haematological and blood chemical parameters as well as progesterone, red blood cell counts, haemoglobin and haematocrit began to decrease during organogenesis and continued to decrease thereafter. Reticulocyte counts significantly increased during organogenesis and decreased thereafter. White blood cell parameters, except for neutrophils, showed significant decreases during the fetal growth stage. Serum progesterone concentration reached its highest level early in organogenesis and decreased thereafter. Total protein, albumin, glucose, cholesterol, calcium, blood urea nitrogen and creatinine decreased significantly during the middle and/or late periods of gestation. In conclusion, the data obtained from the present study can be used as background data for effective evaluation of reproductive toxicology in rabbits, and pregnant rabbits may serve as models of pregnant women in research pertaining to clinical pathology and gestation.

AimTo describe the registry design of the Osaka Emergency Information Research Intelligent Operation Network system (ORION) and its profile of hospital information, patient and emergency medical service characteristics, and in‐hospital outcomes among all patients transported to critical care centers and emergency hospitals in Osaka Prefecture, Japan.MethodsThe Osaka Prefecture Government has developed and introduced an information system for emergency patients (the ORION system) that uses a smartphone application (app) for hospital selection by on‐scene emergency medical service personnel and has been accumulating all ambulance records. Since January 2015, medical institutions have obtained information on the diagnosis and outcome of patients transported to medical institutions, and the ORION system merged these data with ambulance records including smartphone app data.ResultsFrom January 2015 to December 2016, 753,301 eligible patients were registered. The mean age was 58.7 years, and 51.5% of patients were male. After hospital arrival, 39.7% were hospitalized, 58.2% were discharged from hospital, 1.1% changed hospital, and 1.0% died. The most common diagnoses were injury, poisoning, and certain other consequences of external causes. Among the hospitalized patients, 29.2% were continuously hospitalized, 59.0% discharged, 5.2% changed hospital, and 5.8% were dead at 21 days after hospitalization. The most common confirmed diagnosis was diseases of the circulatory system.ConclusionUsing the ORION system developed and operated by Osaka Prefecture since January 2015, we described the epidemiological data of all emergency patients transported to emergency hospitals. Analysis using the ORION database in the future could lead to improvements in the emergency transport system and patient outcomes.
