Twenty-five consecutive total knee arthroplasties were performed with the Solcotrans unit for scavenging postoperative drainage (study group) and were compared with the previous 25 arthroplasties performed without the Solcotrans unit (control group). Mean preoperative hematocrits, estimated blood loss, and fluid replacement for both control and study groups were nearly identical. When the autotransfusion system was not used, 10 patients in the control group required transfusion of a total of 20 units of packed red blood cells, while only two patients utilizing the Solcotrans unit required transfusion of five units of packed red blood cells (P less than .01). The total amount autotransfused in the study group averaged 607.9 mm, and the hematocrit of the scavenged drainage was 29.3%. Samples from all autotransfusions were sent to the microbiology lab for routine culture and were finalized as no growth after 14 days. Serial postoperative hematocrits, platelet counts, prothrombin, partial thromboplastin, blood urea nitrogen, and creatinine values were compared between the two groups. No significant differences were found, and no evidence of coagulopathy, thrombocytopenia or renal dysfunction was found in the study group.
使用Solcotrans装置进行了25例连续的全膝关节置换术以清除术后引流液（研究组），并与之前未使用Solcotrans装置进行的25例关节置换术（对照组）进行比较。对照组和研究组的术前平均血细胞比容、估计失血量和液体补充量几乎相同。当未使用自体输血系统时，对照组中有10例患者共需要输注20单位的浓缩红细胞，而使用Solcotrans装置的患者中只有2例需要输注5单位的浓缩红细胞（P<0.01）。研究组的自体输血量平均为607.9毫升，回收引流液的血细胞比容为29.3%。所有自体输血的样本均送至微生物实验室进行常规培养，14天后确定无生长。比较了两组术后连续的血细胞比容、血小板计数、凝血酶原、部分凝血活酶、血尿素氮和肌酐值。未发现显著差异，研究组未发现凝血障碍、血小板减少或肾功能障碍的证据。
