Study ObjectiveTo determine whether the combination of skin tapes and tissue adhesive is superior to either method alone for laceration repair.MethodsThis was a prospective, longitudinal experiment on six anesthetized swine. Thirty-six full-thickness linear wounds were created using a metal template, then closed using one of three methods: skin tapes over benzoin, tissue adhesive, or a combination of both. The study was done in two parts. Group 1 (immediate excision) animals were euthanized at day zero for skin excision and tensile strength testing following wound repair. Group 2 (delayed excision) had initial wound repair; animals were euthanized at day 35 for skin excision and tensile strength testing.ResultsIn Group 1, the combination of skin tapes and tissue adhesive provided the strongest immediate wound closure. Average mean force for disruption immediately after wound repair was 19.9 lbs. for the tapes and tissue adhesive group compared to 9.6 lbs. for adhesive alone and 8.9 lbs. for tapes alone. The difference in mean force for combination repair vs. tapes alone was 10.3 lbs. (95% CI 4.1, 16.7), and combination vs. adhesive alone was 10.9 lbs. (95% CI 4.7, 17.3). In Group 2, the mean force required for laceration disruption for those repaired with both tape and tissue adhesive was 188.9 lbs. The mean force until wound disruption for tape only was 165.6 lbs., and the mean force until wound disruption for tissue adhesive alone was 118.9 lbs. The difference in mean force required for wound disruption for those repaired with adhesive alone vs. combination repair is 66.5 lbs. (95% CI 21.2, 111.9). The difference in mean force required for wound disruption between the other two groups was not statistically significant.ConclusionsThis study demonstrates that the combination of skin tapes and tissue adhesive provides superior immediate wound closure strength to either of these methods alone in a porcine model.Copyright © 2020 Elsevier Inc.
