[Oxygen transport in patients with ischemic heart disease operated on under a program to preserve the patient's blood].
The results of the studies performed in 112 patients operated on with preservation of the patient's blood are reviewed. This meant pre- and intraoperative blood taking, surgery under normovolemic hemodilution, blood taking and transfusion upon its neutralization with heparin, collection of the blood flowing from drainages. Acid-base balance, pO2, blood Hb level, the degree of Hb saturation with O2, free plasma Hb, platelet count, the level of 2,3-diphosphoglyceric acid have been determined and parameters of oxyhemoglobin dissociation curve have been calculated. Computer monitoring of O2 transport was performed before and after assisted circulation in 28 patients. During surgery it proved possible to collect and return to the patients 10% of the circulating blood. The blood collected during surgery had no negative effect on the hemostasis. The above technique makes it possible to reduce the amount of donor blood used during surgery and has no negative effect on O2 transport.
