Final answer:
The best suture material for interrupted mattress dermal closure from the options is 3/0 polypropylene, as it is non-absorbable and retains tensile strength over time, making it suitable for permanent closures.
Step-by-step explanation:
The suture material best suited for interrupted mattress dermal closure is one that provides strength and is non-absorbable, in case the tissues need longer periods to heal and the suture needs to remain in place without losing its integrity. Among the options given, 3/0 polypropylene (e) is the most appropriate choice. Polypropylene is a non-absorbable suture material that is often used for skin closures, especially when a finer suture is required. It is preferred for its strength, its minimal tissue reaction, and its permanence, as it maintains tensile strength over time. In contrast, polydioxanone (options a and b) and poly glycolic acid (option c) are absorbable sutures that lose their tensile strength over time and are not considered permanent. Dexon (option d), which is another name for polyglycolic acid, is also absorbable and not suited for permanent closure needs.
