Absorbable suture material is
**Core Concept**
Absorbable suture materials are synthetic or natural polymers that are designed to be broken down and absorbed by the body over time, eliminating the need for removal. These materials are typically used in internal tissues or organs where the suture will be in contact with body fluids.
**Why the Correct Answer is Right**
The correct answer is likely Vicryl (polyglactin 910), a widely used absorbable suture material. Vicryl is broken down by hydrolysis, a process in which water molecules cleave the polymer chain, resulting in the formation of smaller fragments that are gradually absorbed by the body. This process typically occurs over 60-90 days, allowing the tissue to heal before the suture is fully absorbed.
**Why Each Wrong Option is Incorrect**
**Option A:** Nylon is a non-absorbable suture material, commonly used in external tissues or skin closure. It is not broken down by the body and must be removed.
**Option B:** Prolene (polypropylene) is also a non-absorbable suture material, known for its high tensile strength and resistance to tissue reaction. It is often used in hernia repairs and other applications where a permanent suture is required.
**Option C:** Mersilene (polyester) is a non-absorbable suture material, often used in cardiovascular and thoracic surgery. It is not designed to be broken down by the body and must be removed.
**Clinical Pearl / High-Yield Fact**
When selecting an absorbable suture material, it's essential to consider the tissue type, the desired absorption time, and the potential for tissue reaction. Vicryl is a popular choice for many applications due to its reliable absorption profile and minimal tissue reaction.
**Correct Answer:** D. Vicryl (polyglactin 910)
