Clinical use of laser tissue soldering with cryoprecipitate has been delayed by the fear of infecting recipients with donor viral products. Solvent-Detergent (S/D) treatment of human plasma is a technique for disrupting membrane enveloped viruses and rendering them noninfectious. Dual 6 cm incisions were created on the dorsum of nine rats and closed with either standard skin staples or with laser activated S/D cryoprecipitate. The animals were sacrificed at one of three time periods: 0, 2, and 4 days. The use of the laser tissue solder significantly improved tensile strength over standard skin closures at all time periods. Tensile strengths (kg force/sq. cm) for the laser group were: 0.22 + 0.08 (0 day), 0.77 + 0.37 (2 day), and 0.84 + 0.30 (4 day). Comparable results for the control group were significantly different (p <0.05): 0.00 (0 day), 0.12 + 0.03 ( 2 day), and 0.36 + 0.21 (4 day). Deactivation of viral particles during preparation of cryoprecipitate does not reduce the utility of this material as a solder during laser bonding. Reduced infectivity of S/D prepared products enhances their clinical utility.
