[Hemodynamic parameters and oxygen regimen of the body in the early postresuscitation period]

In experiments on dogs subjected under light narcosis to a 12--16-minutes full circulatory arrest produced by means of electrotrauma the parameters of the central haemodynamics and oxygen regimen were studied during the early postresuscitational period. Irrespectful of the method of reanimation conducted for 1 hour (closed cardiac massage combined with artificial pulmonary ventrilation or a heart-lung machine), a progressive reduction was noted during the restorative period (3--6 hours) in such indices as the cardiac output per 1 min., stroke volume and left ventricle work. The development of arterial hypotension was prevented by the increased total peripheral resistance. After 9 hours following the reanimation the main parameters of heamodynamics displayed a tendency towards normalization. The circulatory insufficiency was compensated for by an increased oxygen utilization from the blood supply.
