Non-absorbable sutures are used to provide long-term tissue support, remaining walled-off by the body’s inflammatory processes (until removed manually if required). Uses include for tissues that heal slowly , such as fascia or tendons, closure of abdominal wall, or vascular anastomoses.
Non-Absorbable Sutures: 1. Polypropylene sutures (Prolene)- monofilament suture. 2. Nylon suture or Polyamide sutures- monofilament suture. 3. Silk Sutures – Black Braided suture. Silk sutures are no longer used to close the skin because of their poor tensile strength and high tissue reactivity. 4. Polyester sutures- coated and braided suture.
Non absorbable suture materials are vital for specific applications where long-term strength and stability are required. Understanding these sutures, their types, and their advantages can help ensure better surgical outcomes.
Non-absorbable sutures maintain their integrity for an extended period and are typically made from synthetic materials such as nylon or polypropylene. They are preferred for skin closure and other applications where long-term tensile strength is required. Some characteristics include: Material: Commonly made from nylon, silk, or polyester.
Non-absorbable sutures are made from materials that do not degrade within the body. They are available in various forms and structures, which can significantly affect their performance in surgical environments. Some key characteristics include:
Ethilon is a non-absorbable monofilament suture material made from nylon 6 (also known as polyamide). It comes in three colours : black , green and clear . It looks like plastic and feels stiffer than Monocryl or PDS.
Conventional materials for non-absorbable sutures are linen, cotton, silk, stainless steel wire, polyamide (nylon), polypropylene (Prolene) and polyethylene (courlene). Silk suturing has been practiced since the 1890s, and its advantages tend to set the standards for all other sutures.
Non-absorbable sutures are used to provide long-term tissue support, remaining walled-off by the body’s inflammatory processes (until removed manually if required). Uses include tissues that heal slowly, such as fascia or tendons, closure of abdominal wall, or vascular anastomoses.
Non-absorbable sutures are used for surface sutures; require manual removal post-operatively. Depends on UPS size (thickness). Surgeons prefer to use the smallest size that will provide adequate strength. The strength increases as the first digit decreases. 6-0 is a thin comparatively weak suture.
Absorbable sutures are designed to break down naturally in the body over time, eliminating the need for removal. Non-absorbable sutures, on the other hand, require manual extraction. 2. Natural vs. Synthetic: Sutures are crafted from both natural and synthetic materials.
