Absorbable sutures are used to give support to twisted edges quickly, until they have healed enough to endure the off the shelf stresses of the external environment. These sutures are ready either from the collagen of healthy mammals or from synthetic polymers. Synthetic absorbable sutures are hydrolyzed. This is a process by which water slowly and eventually explains the suture filaments. This pds polydioxanone suture leads to the breakdown of the suture’s polymer bonded company. Hydrolysis results in a smaller degree of tissue reaction following implantation in comparison to the enzymatic action of natural absorbable materials. One example of a synthetic absorbable suture is the PDS II monofilament suture made by Ethicon, and which is deemed to be a wonderful addition to the suture market.
PDS II is a monofilament that has resulted in a significant advance in suturing options. A monofilament suture uses a single strand. It stops germs from growing and living in the twisted area, and it ties down without problems. A suture can lose tensile strength rapidly and yet be absorbed slowly. It can maintain adequate tensile strength through twisted healing, followed by rapid absorption. In any case, the strand is eventually completely demolished, leaving no detectable microbes in tissue. PDS II sutures are made up of the polyester polydioxanone. There are many advantages of using the PDS II suture. It combines the features of soft, pliable, monofilament construction with absorbability and extended twisted support for an estimated six weeks. It causes only a slight tissue reaction. This material is widely acceptable and preferred for many types of soft tissue approximation, including pediatric cardiovascular, memory foam, microsurgery and nerve organs tissue, gynecologic, ophthalmic, plastic, the disgestive system, and colonic treatments.
Like other synthetic absorbable suture, PDS II sutures are absorbed in vivo through hydrolysis. Its tensile strength remains around seventy percent 14 days after the implantation, fifty % at month after implantation, and twenty five percent at six weeks after implantation. Absorption is negligible until about the 90th day after the operation and is for all intents and purposes complete within six months. The safety and effectiveness of PDS II sutures in microsurgery, nerve organs tissue, and adult cardiovascular tissue are yet to been established. They may also be impregnated or coated with agents that improve their handling properties, and colored with a dye to increase visibility in tissue. PDS II sutures are available in clear or with a violet dye to increase visibility during a surgery.
PDS Plus Suture has an antibacterial agent added to it. This gives an additional advantage over the regular PDS II. It is indicated for easily use in soft tissue approximation, including easily use in pediatric cardiovascular tissue where growth is expected to occur and ophthalmic surgery. However, contact with cornea and sclera is a noted difference. PDS Plus Suture is not indicated in adult cardiovascular tissue, microsurgery, and nerve organs tissue. These sutures are primarily useful where the combination of an absorbable suture and twisted support is indicated for years of time. Up to six weeks is more often than not desirable.
