Summary

This on-demand teaching session is designed for medical professionals. We will learn how to perform a sub cuticle er running suture, a technique used for cosmetic wind closures in clean, straight lacerations. We will cover topics such as loading the needle, policing anchoring stitches, and grasp the needle in the orientation for a backhand throw. We will also learn how to make alternating bites, pull the suture tight, and use the Aberdeen knot for hand-tying. Join us as we discuss the skill of completing a sub cuticle er running suture.

Description

A subcuticular Aberdeen stitch is a type of suture that is used to close wounds. It is a buried suture, meaning that the knots are buried under the skin and not visible. This type of suture is often used for cosmetic closures, as it leaves no visible scarring.

To perform a subcuticular Aberdeen stitch, the needle is inserted into the skin at one end of the wound and then passed through the subcutaneous tissue (the layer of tissue between the skin and muscle) at the same depth on the other side of the wound. The needle is then brought back up through the skin at the same point where it entered. This creates a loop of suture material under the skin. The needle is then inserted into the skin at the next point along the wound and the process is repeated. This is continued until the entire wound has been closed.

The final knot is tied under the skin, usually at the apex of the wound. This type of knot is called an Aberdeen knot, and it is used to prevent the suture from coming undone.

Learning objectives

Learning Objectives:

Today, we're going to learn how to perform a sub cuticle er running suture for this. You will need a needle driver pickups, citrus scissors, suture and you're behind the knife. See dream board, the sucky together running suture can be used for cosmetic wind closures in clean straight lacerations. Patient with problematic suture removal and young Children as the future will dissolve over time and not require the future to be removed. We're going to start by picking up our needle drivers and loading our needle into them in the orientation for a forehand throat. The first step for the suture involves policing an anchoring stitch about 1 to 2 millimeters away from the top of the wound and securing it with a not after the knot is tied and the short end is trimmed. We will re grasp the needle in the orientation for a backhand throw from here. We'll place the stitch at the top of the wound starting in the dermis and coming out right at the apex at the dermal epidermal junction. We can now start the running portion of the future by taking alternating bites of the left and right side of the wound to do this. I will use the teeth of my forceps in my left hand to grasp the very edge of the epidermis and pull the skin edge up while everting it to make passing the needle through the dermal epidermal layer easier. Be careful not to evert the skin too much as is easy to accidentally come out through the epidermis. Every time we regressed our needle, we want to pull the suture tight which allows the tissue to come together as we advance our needle, be sure to take bites exactly perpendicular from each other to allow for the best tissue approximation. As we make our throw for the final bite, we will leave a loop of suture to tire stitch. Now, you can instrument tie at this point as we've done in the simple running suture video. But for this video, I will be demonstrating in Aberdeen. Not the Aberdeen not is a hand tied, not that is thrown by holding the loop of suture open in your right hand and the suture with the needle on the end of it. In your left hand. From here, we grab the suture below are left hand with our right and allow the loop to slide off our right hand while forming a new loop at the future, we grabbed to make sure not as tight without any slack. It is important to pull the suture in the loop with your right hand until the not slides all the way down from here, you can perform the same movement two more times on the final throw, we will pull the entire suture including the needle through the loop until the entire loop slides down and locks the suture in place. Now, from here, we can re graft suture with their needle drivers and take a bite at the bottom apex of the wound to bury the, not we've just tied. Once you cut your suture, flush against the skin, you've just completed a sub cuticle, er, running suture.
