An experimental study of the portal circulation in the agony period and during resuscitation from clinical death

Summary An inquiry was made into the regularities of the portal system of animals after fatal blood loss and resuscitation following clinical death. The mechanisms capable of providing blood accumulation in the portal circulation at the initial period of revivial were revealed. The following factors which could prevent normalization of the vital activity were noted: a) aggregation of erythrocytes obstructing some small blood vessels, b) possibility of fat drops penetrating into the circulation during agony, c) blood thickening in the portal circulation, inhibiting its movement along the capillary bed and oxygen exchange.(Presented by Active Member AMN SSSR A.
