Acute Hemodilution: Its Effect on Hemodynamics and Oxygen Transport in Anesthetized Man

摘要: The effects of acute normovolemic hemodilution on hemodynamics, oxygen transport, tissue perfusion and blood volume were studied. subjects four patients undergoing total hip replacement with prebleeding under fluoroxene nitrous oxide anesthesia. hematocrit was reduced to 29% 21% by bleeding in two steps simultaneous infusion plasmanate lactated Ringer's solution. major compensation a rise CO 123% 136%. Systemic transport (COX arterial O(2) content) only slightly the arteriovenous difference decreased. Tissue remained excellent. Blood expanded. procedure well tolerated this group selected patients, homologous utilization markedly reduced.
