ABSTRACT

Nikahval B, Tanideh N, MansourianM, Ghaedi A., Maximum tensile strength of natural and synthetic sutures after 7 and 14 day subcutaneous implant in the chicken, rat and rabbit, Online J Vet Res., 17 (2): 84-91, 2013 Data on changes in maximum tensile strength (MTS) of surgical sutures after use in birds, rabbits or rats is lacking. Coated Polyglycolate (PG), coated Polyglactin 910 (Vicryl), Polyglycolic Acid (PGA) and chromic catgut (CC) were lodged subcutaneously and removed after 7 and 14 days in 3 groups each of 5 mature chickens, rats and rabbits. MTS was measured with an Instron testing machine. All suture materials had a decrease in MTS over time. At 7 days, Vicryl retained most and CC lowest MTS values. By 14 days, PG retained highest MTS. For all materials highest tensile strength retention occurred in rats and lowest in rabbits. Results suggested that PG retained most tensile strength in chickens, rats and rabbits.
