[Intraoperative aspiration and reinfusion of autologous blood in resection of abdominal aortic aneurysms with Solcotrans plus].
Quantitative and qualitative assessment of intraoperative aspiration and reinfusion of autologous blood with the Solcotrans was carried out in 11 males (52-79 years) undergoing elective resection of abdominal aortic aneurysms. Hematology, blood chemistry, coagulation parameters and complement activation were studied in the patient's blood at the following time points: preoperatively, before and after heparinisation, after retransfusion of the first and last Solcotrans, 6 and 20 hours postoperatively. In addition the same quality control was performed in the first and last Solcotrans blood. Results (mean values of 11 patients +/- 1 SD): Intraoperatively 2-3 Solcotrans units were salvaged (total 1039 +/- 565 ml) of which 805 +/- 487 ml were retransfused to the patients. As a mean patients required only 1 unit of homologous RBC's (395 +/- 781 ml) intraoperatively. Patient's intraoperative hemoglobin concentration amounted to 10 g/dl or more. Whereas the hemoglobin level in the Solcotrans attained only 8.2 g/dl. Thrombocyte counts (48 +/- 18 x 10(9)/l) and ionized calcium (0.2 +/- 0.4 mmol/l) were significantly depressed when compared to the preoperative patient values (p < 0.05). The protein concentration remained within normal limits in the patient's and in the Solcotrans blood. Complement activation (C4a, C5a [des Arg]) showed a significant increase after initiation of surgery and there was no significant difference between the solco- or patient blood. Whereas plasma free hemoglobin, coagulation and fibrinolysis parameters showed a significant elevation in the Solcotrans blood. In conclusion the solcotrans system offers a fast, efficient and simple method for salvage and retransfusion of intraoperative autologous blood.
