[Autologous fibrin glue--preparation and clinical use].
Fibrin tissue adhesive is a tissue adhesive in which the two components are fibrinogen concentrate and a thrombin solution, respectively. In autologous fibrin tissue adhesive, the fibrinogen is prepared from the patient's own blood in contrast to the fibrin adhesive available commercially where the fibrinogen is prepared from pooled donor plasma. In 42 heart and lung operations, autologous fibrin tissue adhesive prepared by a new method was employed in which the fibrinogen is separated from the patient's own plasma by precipitation with ethanol. Either 44 or 88 ml blood was employed for concentration of the fibrinogen. This resulted in 2.5 ml and 4.9 ml fibrinogen concentrate which was mixed with 0.3 parts of thrombin solution containing calcium and aprotinin (fibrolysis inhibitor) so that the total volumes of tissue adhesive were 3.3 ml and 6.4 ml. Production of autologous fibrin tissue adhesive is uncomplicated and takes less than 90 minutes. A new method of production of autologous tissue adhesive based on ethanol is described. The fibrin tissue adhesive prepared in this manner has a high concentration of fibrinogen and is effective as a haemostatic and as an adhesive in surgical operations and it has the further advantage that it is not associated with the risk of transmission of viral or for immunological reactions.
