Red Cell Preservation in Protein‐Poor Media: III. Protection Against in vitro Hemolysis

Abstract: Red cells stored under blood bank conditions normally show less than 1% spontaneous in vitro hemolysis even after 5 weeks; larger hemolysis may be found if the cells are suspended and stored in a saline-adenine-glucose (SAG) solution with very little trapped plasma. Delay of the addition of the suspension medium, return of 25 ml plasma after a maximal plasma harvest, addition of mannitol 10-30 mmol.1(-1) to the suspension medium were alternative and effective ways of keeping the spontaneous lysis within normal… Show more

“…We confirmed that both mannitol and sucrose had a marked protective effect against spontaneous storage hae molysis in the SAG system [7], The composition was changed, therefore, into the so-called SAGM or Sagman solution, which we tested in clinical trials in 1980 and which we have used since [8,9]. The addition of 30 mmol/1 mannitol (3 mmol per blood unit) has been found not to be controversial in practice.…”

“…The initially higher content of plasma hemoglobin in RBC-Hct 79 and the higher content of hemoglobin in plasma of red blood cells at the end of the storage period, as compared with whole blood, may have been caused by mechanical stress during centrifu gation [33], In RBC-Hct 55 hemolysis did not deviate from normal values of red blood cells as have been reported previously for storage in CPD-SAG solution [26,27,33]. Therefore, the requirements for remaining plasma and leukocyte content [26] seem to be satisfied in this preparation (cf.…”

“…3,13 No entanto, eritrócitos preservados ainda considerados adequados para transfusão, podem provocar reações graves, ou mesmo a morte, em pacientes críticos, em especial os que apresentam comorbidade cardíaca e respiratória ou em choque séptico, ou mesmo os recém-natos. [17][18][19][20] O controle de qualidade das bolsas eritrocitárias inclui determinações laboratoriais a serem realizadas após a coleta e fracionamento do sangue e durante a preservação.…”

“…Assim, multiplicaram-se estudos sobre os eritrócitos envolvendo morfologia, metabolismo e sobrevida em condições de armazenamento. [1][2][3][4][5][6] O emprego e o aperfeiçoamento de métodos de controle de qualidade em laboratório clínico se desenvolveram na segunda metade do século, com provas substanciais de que o seu emprego pode reduzir significativamente as margens de erro. 7 A demanda universal da luta contra a disseminação da síndrome da imunodeficência adquirida (AIDS), bem como de outras doenças infecciosas, em especial a partir da década de 80, acabou contribuindo de forma decisiva para a implantação de métodos mais eficientes para a garantia e o controle de qualidade em laboratórios clínicos e em hemocentros.…”
