Identify the following non-absorbable suture?

Appeared in: NORCET 3 - 2022 (Shift-1)

Explanation

Polypropylene, commercially known as Prolene, is a synthetic monofilament suture.
It is classified as non-absorbable because it is not broken down by the body and provides permanent tensile strength.
Due to its inert nature and strength, it is used for tissues that require long-term support, such as in vascular anastomoses or hernia repair.
The flowchart provided in the image correctly lists Polypropylene under the 'Non Absorbable' category.

Option A: Vicryl (Polyglactin 910) is an absorbable suture. It is designed to be broken down and absorbed by the body over several weeks.
Option C: Poliglecaprone, with the brand name Monocryl, is an absorbable suture. It is known for its rapid absorption.
Option D: Catgut is a natural absorbable suture. It is digested by the body's enzymes and has a shorter duration of tensile strength.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Surgical Sutures as background academic context rather than a clinical decision trigger.
Understanding the difference between absorbable and non-absorbable sutures is critical for patient safety and proper wound healing. Using the wrong type can lead to wound dehiscence, infection, or unnecessary foreign body reaction.
A nurse's role includes monitoring the wound post-operatively for signs of infection or healing complications. For non-absorbable skin sutures, the nurse is often responsible for their timely removal.
What if the patient had a history of keloid scarring? The surgeon might prefer to use absorbable subcuticular sutures (like Monocryl) instead of non-absorbable skin sutures to minimize skin trauma and the inflammatory response that can contribute to keloids.

How to Approach the Question

First, carefully read the question and identify the key term: 'non-absorbable suture'.
Examine the provided image, which includes a helpful flowchart classifying sutures. This is a direct clue.
Locate the 'Non Absorbable' column in the flowchart.
Scan the list under 'Non Absorbable': Silk, Polypropylene, Polyethylene, etc.
Now, review the multiple-choice options: Vicryl, Polypropylene, Poliglecaprone (monocryl), Catgut.
Compare the options to the 'Non Absorbable' list in the flowchart. You will find 'Polypropylene' is listed there, making it the correct answer.
