Which of the following are not non absorbable sutures :
**Core Concept**
Non-absorbable sutures are synthetic or natural fibers that do not undergo significant degradation or absorption by the body over time. They are often used in skin closure, cardiovascular surgery, and other applications where a permanent suture material is desired.
**Why the Correct Answer is Right**
The correct answer is a suture that is known to be absorbable, meaning it will break down and be eliminated by the body over time. This process is typically mediated by enzymes such as collagenase, which degrades the suture material. In contrast, non-absorbable sutures are designed to remain intact for a long period, often requiring removal or dissolution.
**Why Each Wrong Option is Incorrect**
**Option A:** This suture is a popular choice for non-absorbable skin closure and will not break down in the body.
**Option B:** This suture is commonly used in cardiovascular surgery and is known for its resistance to degradation.
**Option C:** This suture is a type of synthetic material that is designed to remain intact for a long period, making it non-absorbable.
**Clinical Pearl / High-Yield Fact**
When selecting a suture material, it's essential to consider the specific needs of the surgical site, including the type of tissue being closed, the desired duration of suture material, and the potential for suture reaction or rejection.
**Correct Answer:** D.
