Autotransfusion of shed mediastinal blood after cardiac surgery. A prospective study
1978
In a randomized prospective study of patients having cardiac surgery, autologous blood collected from mediastinal tubes was autotransfused preferentially in 63 patients (ATS), whereas 51 patients received bank blood for transfusion (control). Comparison of the two groups showed no significant difference in regard to age, sex, operations performed, or total postoperative bleeding (ATS 813 ± 121 ml. per square meter versus control 711 ± 93 ml. per square meter; N.S.). Although mean postoperative blood replacement vas similar in the two groups (ATS 4.3 ± 0.6 units per patient versus control 4.8 ± 0.6 units per patient), requirements for transfusion of stored bank blood were reduced by 50 percent in the ATS group (ATS 2.4 ± 0.3 units per patient versus control 4.8 ± 0.6 units per patient; p
