[Restoration of the vital functions of animals resuscitated with the help of a donor following prolonged circulatory arrest].

Experiments were carried out on anesthetized dogs which had sustained a 15--20-minute circulatory arrest and were reanimated with the aid of donor circulation. In the I group of experiments the blood flow from the donor was directed to the heart of the revived dog, and in the II group--to the heart and the brain. Unlike other methods, donor reanimation, especially in the II variant of experiments, promoted a more rapid recovery of the vital functions of the organism and increased the number of survived animals. In spite of a complete apparent recovery of dogs after a prolonged circulatory arrest there were different changes in their brain depending both upon the duration of clinical death and the reanimation methods.
