What is Subcuticular stitch?

This technique generally follows dermal suturing to complete a layered closure. It is often performed with an absorbable suture, however, non-absorbable material can be used and removed once the wound has reached an adequate strength. The technique can be thought of as a buried continuous suture.

What is the most common suture knot?

The two-hand square knot is the easiest and most reliable for tying most suture materials. It may be used to tie surgical gut, virgin silk, surgical cotton, and surgical stainless steel.

How do you end a simple continuous suture?

Simple continuous sutures are placed over the length of the wound, re-penetrated the epidermis, and passed dermally or subcutaneously. It is important to place each stitch on equal distance in the simple continuous suture technique. The application is terminated by a single knot at the end of the suture line.

Is Subcuticular and subcutaneous the same?

The term, “intradermal suture” is a more appropriate substitute for the “subcuticular suture” because the suture passes through the dermis rather than being placed underneath in the subcutaneous tissue. The term intradermal is not only anatomically correct but is also self explanatory.

How long do subcutaneous stitches last?

The time it takes for dissolvable or absorbable stitches to disappear can vary. Most types should start to dissolve or fall out within a week or two, although it may be a few weeks before they disappear completely. Some may last for several months.

What knot do doctors use for stitches?

The square knot is traditionally used. First, the tip of the needle holder is rotated clockwise around the long end of the suture for two complete turns (see the image below). The tip of the needle holder is used to grasp the short end of the suture.

How long does it take for subcutaneous sutures to dissolve?

Uses of Absorbable Sutures Absorbable sutures vary widely in both strength and how long they will take for your body to reabsorb them. Some types dissolve as quickly as 10 days, while other types can take about six months to dissolve.

How is a knot formed in a subcuticular suture?

Once a secure knot is formed in the apex, pass the needle back deep through the wound emerging adjacent to the wound, this will bury the knot. On the final knot bring the needle through the loop to secure the knot. If you create too many loops the knot will increase in size and is more likely to erode through the skin.

Do you have to use absorbable sutures with buried knots?

Keep in mind that the knots may take a bit longer to resorb due to the increased amount of suture material left inside the wound. Always use absorbable sutures when using this technique. The subcutaneous suture is similar to the interrupted sutures with buried knots, but it is placed in the depth of the tissue in a surgical or traumatic wound.

Which is the best suturing technique for wound closing?

To enhance eversion. The mattress suture provides more eversion up to the point where you may get opening of the wound edges. You may consider using the far-near suturing technique which is a variation of the vertical mattress suture. To bring more volume or quantity of tissue to the closure area.

What are the pros and cons of knotless sutures?

The disadvantage, however, is that these knots can be potential breeding grounds for bacteria, which may then predispose the wound to an increased risk of infection and stitch abscesses. Knots may also cause localized irritation and granulation, which may impair wound healing.
