title: [Changes in systemic hemodynamics caused by intra-arterial and intravenous autoperfusion of small blood volumes].
abstract: Changes of general peripheral resistance in response to autoperfusion both prior to and after blockade of alpha- and beta-adrenoreceptors depended on its initial level: at a relatively low initial value autoperfusion increased the vascular resistance whereas at high value decreased it. During maximal shifts of hemodynamic parameters the venous return prevailed over the cardiac output. The pressor effect was practically unrelated to the way of blood administration.
