Takeaways
- 🧵 Sutures are referred to as 'suture' in medical terminology, rather than the everyday term 'stitches'.
- 📏 Suture sizes range from thick diameters to very thin threads, with standard sizes historically ranging from 1 to 6, but now including sizes 0, double-0, triple-0, and up to quadruple-0 sutures.
- 👁️🗨️ The smallest suture size, an 11-0 suture, is incredibly tiny, about a third of the diameter of a human hair, which is comparable to a 7-0 suture.
- 👁️ Good eyesight is crucial when working with very small sutures, especially in conditions like laparoscopic or microscopic surgery where visibility can be limited.
- 🧪 Sutures can be either absorbable, which are broken down and absorbed by the body over time, or non-absorbable, which remain in the body indefinitely.
- 🩸 Absorbable sutures are preferred for areas with rapid healing and good blood flow, while non-absorbable sutures are used for areas that heal slowly or where long-term support is needed, like in blood vessels or tendons.
- 🧵 Sutures are also classified by the filament structure into monofilament, which is a single strand of material, and multifilament, which consists of multiple strands woven or braided together.
- 🔍 Monofilament sutures are smooth and less likely to harbor bacteria, but can be more challenging to knot due to their 'memory' that makes them want to retain their original shape.
- 🧵 Multifilament sutures are easier to knot but have more surface area that can trap bacteria, making them less ideal for use in infected areas.
- 📦 Suture packaging provides important information including the suture size, material, needle type, and expiration date, which should always be checked before use.
- ⚖️ The choice between monofilament and multifilament, as well as absorbable and non-absorbable sutures, depends on the specific requirements of the surgical procedure and the characteristics of the tissue being sutured.
Q & A
What is the medical term for stitches?
-The medical term for stitches is 'sutures'.
How many standard suture sizes were originally developed?
-Originally, six standard suture sizes were developed.
What is the smallest suture size mentioned in the transcript?
-The smallest suture size mentioned is 11-0 suture.
Compared to a human hair, how thick is an 11-0 suture?
-An 11-0 suture is about a third of the diameter of a human hair.
What are the two main types of suture materials based on their absorption by the body?
-The two main types of suture materials are absorbable and non-absorbable.
Why would a surgeon choose an absorbable suture for deeper parts of the body?
-A surgeon might choose an absorbable suture for deeper parts of the body to avoid the need for a second procedure to remove the sutures, as they will naturally dissolve over time.
What is the advantage of using non-absorbable sutures for suturing arteries?
-Non-absorbable sutures are used for arteries because they will not dissolve too quickly, ensuring that the sutures hold the blood vessel together long enough for it to heal, especially under high pressure.
How does the structure of monofilament sutures affect their use in surgery?
-Monofilament sutures have a smooth surface which allows them to glide through tissues easily, but they can be more challenging to knot securely due to their 'memory' that makes them want to retain their original shape.
Why are multifilament sutures not recommended for use in areas prone to infection?
-Multifilament sutures have many tiny strands woven together, creating nooks and crannies where bacteria can hide and multiply, making them less suitable for use in areas prone to infection.
What is the main material used to make Vicryl sutures?
-Vicryl sutures are made from a polymer called polyglactin 910.
What are the four main types of needles described in the transcript?
-The four main types of needles described are taper point, blunt point, conventional cutting, and reverse cutting needles.

😀 Introduction to Sutures and Their Varieties
Mark Sowers introduces the concept of sutures, emphasizing the medical preference for using specialized terms. He explains that sutures come in various sizes and types, with doctors having personal preferences. Suture sizes range from thick diameters to very thin threads, with a standardization that includes sizes 0 to 11-0, where 11-0 is the smallest. Sowers also discusses the importance of visibility and eyesight when working with sutures, especially in darker surgical conditions.
🧵 Absorbable vs. Non-Absorbable Sutures
The paragraph delves into the classification of sutures as either absorbable or non-absorbable. Absorbable sutures are broken down by the body's enzymes and eventually absorbed, making them suitable for areas with rapid healing and high blood flow. Non-absorbable sutures, in contrast, remain in the body indefinitely and are used in areas that require long-lasting closure, such as arteries or tissues with low blood flow like tendons. The choice between absorbable and non-absorbable sutures depends on the specific surgical context and the desired healing outcomes.
🧵 Monofilament vs. Multifilament Sutures
This section distinguishes between monofilament and multifilament sutures based on their composition. Monofilament sutures are made from a single strand of material and have memory, which means they retain their shape and can be challenging to knot. They are also less likely to harbor bacteria due to their smooth surface. Multifilament sutures, made from multiple strands woven or braided together, are easier to knot but provide more surface area for bacteria to hide. Their use is not recommended in areas prone to infection. The choice between monofilament and multifilament depends on the surgical site and the need for reduced bacterial colonization.
📦 Types of Sutures and Their Applications
The paragraph discusses various types of sutures, including absorbable monofilament sutures like Monocryl, PDS, and chromic gut, and non-absorbable monofilament sutures like Prolene and surgical steel. It also covers absorbable multifilament sutures like Vicryl and non-absorbable multifilament sutures like Ethibond and silk. Each suture type has specific applications based on its properties, such as gut sutures for areas with rapid healing and Prolene for long-lasting repairs like hernia surgery. The packaging of sutures usually provides essential information about the type, material, and needle details, aiding in the selection process.
🧵 Uses of Prolene and Vicryl Sutures
Prolene, a non-absorbable monofilament suture, is highlighted for its long-lasting nature, making it ideal for securing surgical mesh in hernia repairs and vascular procedures. Vicryl, an absorbable multifilament suture made of polyglactin 910, is versatile and commonly used for general soft tissue approximation. Its purple dye helps in identification, and it's favored for its ease of knotting and eventual absorption by the body.
🪡 Types of Suture Needles
The video script describes four main types of suture needles: taper point, blunt point, cutting, and reverse cutting. Taper point needles are round and taper to a sharp point, suitable for general use. Blunt point needles have a softer tip for delicate tissues to prevent tearing. Cutting needles have a triangular shape with sharp edges along the shaft for tough tissues. Reverse cutting needles have the sharp edge on the outside curve, which helps in holding the suture in place better. Suture packaging typically includes labels with detailed information about the suture size, material, needle type, and size, and the expiration date, assisting in the selection of the appropriate suture for a procedure.
