Objective: Even though red blood cells from cord blood (CB) have been investigated for many years for the purpose of autologous retransfusion to newborns this technique is still far from clinical routine. In severely ill neonates fresh frozen plasma from donors is frequently transfused for volume expansion or as a source of coagulation factors, but autologous plasma transfusion has not been described. Methods: We investigated 35 CB preparations of preterm and term newborns for sterility and fast provision of either red blood cell concentrate (RBC) or plasma with respect to quality of both components and time needed for bacterial testing. CBs and 34 control RBCs from regular blood donors were collected in citrate-phosphate-dextrose solution (CPD). RBCs and plasma were prepared in sodium-adenine-glucose-mannitol (SAGM). Swabs were taken from the placenta for cultivation of bacteria. Quality of stored blood was assessed in RBCs on day 0, 3, 8, 14 and 42, respectively, and tests for activated coagulation were done in |
