Survival of dogs in the recovery period after prolonged hypovolemic hypotension

The survival rate and completeness of neurological recovery of functions of the CNS in the postresuscitation period were investigated in dogs in relation to the duration of hypovolemic hypotension, the arterial pressure level, and subsequent transfusion therapy. Administration of dextran in the early recovery period after hypovolemic hypotension in animals for 4 h increased the number of surviving dogs and led to complete restoration of functions of the CNS.
