Abstract
Various methods of making fibrin tissue adhesive from a patient's own blood were evaluated. The method using ammonium sulfate for fibrinogen preparation produced the greatest bonding strength.The average bonding strength of the commercially manufactured adhesive and of the autologous fibrin tissue adhesive were compared at 10 minutes and 30 minutes after glucing together lxl cm samples of fresh human dura. Results indicate the commercial glue holding 57 gms/cm2 at 10 minutes and 123 gms/cm2 at 30 minutes, while autologous glue prepared with the “ammonium sulfate method” has a bonding strength of 41 gms/cm2 at 10 minutes and 217 gms/cm2 at 30 minutes.
