Share

Summary

This on-demand teaching session will provide medical professionals with an introduction to the figure of eight suture technique. We'll cover how to place a simple suture across the wound, and then how to tie it off so that it assumes the figure of eight formation. Expect to gain confidence in your technique and proficiency in closing complex wounds.

Description

A figure-of-8 suture is a type of suture that is used to close wounds. It is characterized by two loops of suture material that are placed around the wound, in the shape of a figure 8. The first loop of suture material is placed through the skin on one side of the wound, then through the skin on the opposite side of the wound, and then back through the skin on the first side of the wound. The second loop of suture material is placed through the skin on the same side of the wound as the first loop, but about 1 cm away. The suture is then tied, creating two loops of suture material that encircle the wound.

Figure-of-8 sutures are commonly used to close wounds that are under tension or that are prone to gaping. They are also used to evert (turn outward) the edges of a wound, which helps to prevent the wound from closing inward and forming a scar.

Here are the steps on how to perform a figure-of-8 suture:

  1. Prepare the wound by cleaning it with soap and water.
  2. Anesthetize the area around the wound.
  3. Insert the needle through the skin on one side of the wound, about 4-8 mm from the edge.
  4. Pass the needle through the skin on the opposite side of the wound, at the same distance from the edge.
  5. Pass the needle back through the skin on the first side of the wound, just next to where it first entered.
  6. Pass the needle through the skin on the same side of the wound, about 1 cm away from where it first entered.
  7. Tie the suture, creating two loops of suture material that encircle the wound.
  8. Repeat steps 3-7 until the wound is closed.

It is important to note that figure-of-8 sutures should only be placed by a qualified healthcare professional. If you have a wound that requires stitches, please see a doctor or other healthcare provider.

Here are some of the advantages of using a figure-of-8 suture:

  • It is very effective at closing wounds that are under tension or that are prone to gaping.
  • It helps to evert (turn outward) the edges of a wound, which helps to prevent the wound from closing inward and forming a scar.
  • It is relatively easy to place, even for beginners.

Here are some of the disadvantages of using a figure-of-8 suture:

  • It can leave a wider scar than other types of sutures.
  • It can be more difficult to remove than other types of sutures.
  • It can be more uncomfortable for the patient than other types of sutures.

Overall, figure-of-8 sutures are a versatile and effective type of suture that can be used to close a variety of wounds. However, it is important to note that they should only be placed by a qualified healthcare professional.

Today, we're going to learn how to perform a figure of eight suture for this. You will need a needle driver pickups, suture, scissors, suture, and you're behind the knife scootering board. The figure of eight suture can be used to achieve tension across an entire wound where a single stitch may pull through the tissue. It can also be used to tie off any small arteries or veins that are encountered. The suture is a variation of the horizontal mattress suture and we'll start the same way by placing a simple suture across the wound. Now, unlike the horizontal mattress where you enter back in at this point, we're going to come back across the wound to the side we started on and repeat the same throw. Now, you will notice that the suture is coming out on the opposite side of the wound than when we had started. We're going to instrument tie these two tales together. At this point, you will see as we tie this not down, the future will be crossing in the middle and creates the shape of a number eight. Hence the name figure of eight. Once you cut your tales, you have completed the figure of eight suture.
