Abstract
The purpose of this study was to determine if solid material reinforcement of a liquid albumin solder coagulum could improve the cohesive strength of the solder and thus the ultimate breaking strength of the incision repair in vitro. A 50%(w/v) bovine serum albumin solder with 0.5 mg/mL Indocyanine Green (ICG) dye was used to repair an incision in bovine aorta. The solder was coagulated with an 806 nm CW diode laser. A 50 micrometer thick poly(DL-lactic-co-glycolic acid) film was used to reinforce the solder (the controls had no reinforcement). Acute breaking strengths were measured and the data were analyzed by one-way ANOVA (P less than 0.05). Multiple comparisons of means were performed using the Newman- Keuls test. Observations of the failure modes indicated cohesive strength reinforcement of the test specimens versus the controls. At the higher laser powers used in this study (400 and 450 mW), the reinforced solder was consistently stronger than the controls. Reinforcement of liquid albumin solders in laser-assisted incision repair may have mechanical advantages in terms of acute breaking strength over conventional methods that do not reinforce the cohesive strength of the solder.
