A mobile system for the treatment of accidental hypothermia with extracorporeal circulation.
When deep accidental hypothermia causes circulatory failure, the best chance of survival is treatment with extracorporeal circulation (ECC) and warming of the blood. This may be difficult to achieve if the patient is first admitted to a hospital without a department of thoracic surgery. Our aim was to test a lightweight mobile system for ECC. The equipment could be transported almost anywhere, making it possible to start ECC on the spot and during transfer. The system was tested on six hypothermic pigs, two of the pigs at the institute laboratory, two of the pigs in a normal ambulance, and two of the pigs in an air force rescue helicopter. All of the pigs were transported back to the institute for warming to normal temperature. After warming, and the ECC stopped, all the pigs were in sinus rhythm and had an obviously satisfactory circulation. It is possible to bring a lightweight ECC system to the unstable patient. Treatment is possible in any hospital, ambulance or helicopter.
