title: Autologous fibrin tissue adhesive: factors influencing bonding power.
abstract: Bonding power of Autologous Fibrin Tissue Adhesive (AFTA) is directly related to its fibrinogen concentration. By increasing the ammonium sulfate concentration 100% during fibrinogen precipitation, the bonding power of two glued 1-cm2 pieces of human dura almost doubled. No relationship between blood fibrinogen level and bonding power was demonstrated. Comparing AFTA with Fibrin Sealant, the commercial fibrin tissue adhesive, shearing strength between two glued pieces of human dura with AFTA was less 10 minutes and greater 30 minutes after gluing. Gluing a TORP (Richards) to a 1-cm2 piece of human dura yielded generally somewhat greater bonding power when using Fibrin Sealant. Autologous Fibrin Tissue Adhesive provides bonding power adequate for middle-ear surgery, eliminates transmission of viral diseases and, unlike Fibrin Sealant, AFTA is available in the United States.
