Abstract

We attempted to analyze the efficacy and safety of an extensive blood saving program applied in a large cohort of patients. Blood saving included reinfusion of intraoperative predonated blood, aprotinin (2 million KIU) in the prime solution, reinfusion of any residual volume, postoperative acceptance of normovolemic anemia (hematocrit > or = 25%) and autotransfusion of shed blood. SETTING, EXPERIMENTAL DESIGN AND PATIENTS: In our general hospital with a heart surgery service (1150 cases/year), we studied the records of 527 non-selected consecutive patients, who were prospectively treated with this program being applied in primary myocardial revascularization between. We avoided the use of donor blood in 86.9% of the patients requiring a mean of 0.2+/-0.01 unit of donor blood per patient. No repeat thoracotomy for bleeding was needed in any patient. Univariate analysis revealed that female gender, a low level of hematocrit, high age, a small stature, weight, body surface area, and red cell volume prebypass significantly (p<0.001) were correlated to treatment with donor blood. Multiple regression showed that a small red cell volume and a low prebypass hematocrit were the most (p<0.0001) significant predictors for the use of donor...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
