[Haemodynamic effects of dextran 6% in the treatment of haemorrhage (author's transl)].

An isovolaemic infusion of dextran 6% after 1000 ml haemorrhage produced an increase in blood volume. This response persisted over a 4 h period, during which time a marked increase of venous return, stroke volume and cardiac output was be demonstrated. Improvement in the central circulation was produced through a significant drop in total peripheral resistance. The administration of the plasma expander was associated with an acute renal hyperperfusion.
