Sutures made of polypropylene are not absorbed by the body and provide long-term support for wounds. Sutures made of polypropylene are tinted blue, so they may be easily identified after surgery.
Orthopedic, plastic, micro, general closure and cardiovascular procedures benefit from the high tensile strength of polypropylene sutures. The brand name "Prolene" is often used to refer to sutures made of polypropylene.
Indications
Sutures made of monofilament polypropylene are ideal for approximating and ligating a wide variety of soft tissues, making them useful in various surgical applications. Unigene is non-adherent and physiologically inert; it is not absorbed and is not degraded by tissue enzymes. It is meant to be installed permanently.
Properties
Knots tied with these materials are very secure, can be tied quickly and easily, have high tensile strength, and cause minimal tissue damage throughout their journey through the body because they lack flexibility when tied.
Synthetic, non-absorbable suture made of polypropylene
Sterilized monofilament polypropylene surgical suture is made from an isotactic crystalline stereoisomer of polypropylene, a synthetic linear polyolefin. Molecularly, Polypropylene Surgical Suture is represented as (C3H6)n. Both white and phthalocyanine blue polypropylene surgical sutures are available.
Polypropylene suture is pre-attached to various needle sizes and kinds made from stainless steel.
Conclusion
Tissues exhibit a mild inflammatory response when polypropylene sutures are first introduced, but eventually, the suture is completely encased by fibrous connective tissue. Polypropylene surgical suture does not degrade or get weakened by the action of tissue enzymes. Hence it is not absorbed.
Since it causes little to no biological response when used as a suture, it is ideal for wounds where little disruption to the patient's tissue is required.
