Takeaways
- 📚 Practice is essential for mastering suturing techniques, and using simulators like Vadas is an effective and practical way to improve skills.
- 💡 The simplest way to tie a knot is with an instrument tie, leaving a short tail and wrapping twice for the first throw and once for subsequent throws to secure the suture.
- 🌟 The key to a simple suture is entering and exiting the tissue at 90 degrees, which helps in approximating the skin beautifully and minimizing scarring.
- 🩹 Buried sutures are useful for minimizing skin tension and are particularly beneficial when using absorbable sutures with either gluing or steri-strips.
- 🛠️ Vertical mattress sutures are more secure and help in pulling tissue between each throw together, which is especially useful for wounds under tension or those that gap open.
- 🔄 Horizontal mattress sutures are similar to vertical mattress sutures but are placed in a horizontal line, offering a faster alternative while still providing strength and minimal inversion of skin edges.
- 🔺 The figure-of-eight suture is a quick and strong alternative to a horizontal mattress suture, suitable for areas with significant gaping or need for strength in closure.
- 🏃♂️ Running sutures allow for faster closure of wounds and require consistent bite sizes and advancement for a neat and uniform appearance.
- 🔒 Running locking sutures are a variation that locks the stitch each time, preventing the suture from untying and providing additional security in quickly closing wounds like scalp lacerations.
- 🌈 Cosmetic subcuticular closures involve running a stitch under the skin, offering a seamless closure with no sutures in the wound, ideal for aesthetically sensitive areas.
Q & A
What is the primary focus of the video?
-The primary focus of the video is to instruct viewers on various suture techniques and a stapling technique for skin closure, using a suture skills simulator.
Why is practicing suturing important?
-Practicing suturing is important because it helps to develop and refine the skill, which is essential for effective wound closure and proper healing. Regular practice leads to better outcomes and more efficient suturing.
What is the Vadas new suture skills simulator mentioned in the video?
-The Vadas new suture skills simulator is a realistic and lifelike training device designed to help individuals practice and improve their suturing skills without the need for cadaveric or animal material.
How does the video demonstrate tying a knot for suturing?
-The video demonstrates tying a knot by using an instrument to pass the suture through the skin, leaving a short tail, and then wrapping the long end around the short end twice before pulling it across the wound to lock it down.
What is the significance of a surgeon's knot in suturing?
-A surgeon's knot is significant because it provides a secure lock in place, ensuring that the suture does not come loose. It is particularly important for wound closure as it helps maintain the approximation of skin edges for proper healing.
How is a simple suture performed according to the video?
-A simple suture is performed by inserting the needle on one side of the wound and then bringing it out on the other side. The needle is held in the middle, and the suture is tied using the taught instrument tie method, ensuring the skin is well approximated.
What is a buried suture and when is it used?
-A buried suture is a type of suture where the knot and the suture itself are hidden beneath the skin's surface. It is used when a clean and minimal scar appearance is desired, often with absorbable sutures and in conjunction with skin glue or steri-strips.
What is a vertical mattress suture and its purpose?
-A vertical mattress suture is a technique where the needle enters the skin far away from the incision, comes back closer to it, and then repeats the process on the other side. This method helps to pull the tissue together, providing a more secure closure and reducing tension on the skin edges.
How does the video describe the use of a horizontal mattress suture?
-The horizontal mattress suture is a technique where two simple sutures are effectively combined into one. The needle enters the skin and takes a bite, then advances the same distance on the other side, creating two rows of suturing in a horizontal line. This method is faster than two separate simple sutures and is useful when the skin doesn't need inversion.
What is the purpose of a figure-of-eight suture?
-A figure-of-eight suture is used in situations where strength is needed, such as in general surgery for large, gaping wounds. It involves making a series of simple sutures without turning the needle, resulting in a crossed pattern that resembles the number 8. This suture is fast and strong but may not be as cosmetically pleasing as other methods.
How does the video demonstrate the removal of staples from a wound?
-The video demonstrates the removal of staples using a staple remover, which grabs the staple, straightens its ends, and then lifts it out of the wound. Alternatively, a needle driver or clamp can be used to manually spread and straighten the staple before removing it.

🩺 Introduction to Suturing Techniques
Michel Zen introduces the video by stating that he will instruct on 10 different suture techniques and a stapling technique for skin closure. He emphasizes the importance of practice in becoming proficient at suturing and mentions the use of cadaveric and animal materials at Duke for practice. However, he acknowledges the impracticality and cost-ineffectiveness of these methods and introduces a new suture skills simulator that he helped develop. This simulator is described as incredibly lifelike and portable, making it an ideal tool for anyone looking to practice suturing.
📘 Learning to Tie Knots and Simple Sutures
The paragraph begins with a lesson on tying knots using an instrument, specifically a needle driver. The technique involves leaving a short tail of suture, wrapping the long end twice around the short end, and then pulling the short end across the wound to lock it down. This method is used to create a surgeon's knot, which ensures the suture does not come loose. Following this, the instructor teaches how to perform a simple suture, which involves entering the tissue at 90 degrees on both sides to approximate the skin beautifully. The importance of not running the needle all the way across is highlighted to avoid unnecessary scarring, and the concept of varying stitch distances based on tissue needs is discussed.
🌟 Advanced Suturing Techniques
This paragraph delves into more complex suturing techniques, starting with the vertical mattress suture, which is used to close gaps in the skin where a simple suture might pull through. The vertical mattress suture involves entering the skin far away and then coming back closer to the incision, which helps to pull the tissue between the suture throws together. The instructor also discusses the horizontal mattress suture, which is similar but in a horizontal line, and the figure-of-eight suture, which is a quick and strong method suitable for large, gaping wounds. The paragraph concludes with an explanation of the simple running suture, which is a fast and efficient way to close a wound.
🔍 Subcutaneous and Deeper Closures
The focus of this paragraph is on subcutaneous and deeper closures. The instructor demonstrates how to perform a buried suture, which involves taking horizontal bites in the deep dermis on both sides of the wound to bring the skin edges together without any suture in the wound itself. This technique is particularly useful for cosmetic closures as it leaves no visible suture marks. The paragraph also covers the closure of the fascia layer, which is often done with simple sutures, and the importance of starting from the ends of the wound to minimize tension. The use of a Vatel 3500 simulator to practice these techniques is mentioned, emphasizing its realistic feel and the ability to adjust tension levels.
🩱 Skin Stapling and Staple Removal
The final paragraph discusses skin stapling as an alternative to sutures, especially in situations where quick closure is needed. The instructor explains the process of approximating the skin and using a stapling device to close the wound, highlighting the benefits of fast closure and the eversion of skin edges that stapling provides. The paragraph concludes with a demonstration of staple removal using a staple remover, a needle driver, or a clamp. The importance of careful removal to minimize pain and the potential need to rock the staple from side to side for a smoother extraction is emphasized.
