A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
The body responds to postoperative wounds in the same manner as it does to tissue damage acquired in other circumstances. The inflammatory response is designed to create homeostasis. This first step is called the inflammatory stage. [1] The next stage and wound healing is the infiltration of leukocytes and release of cytokines into the tissue ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The horizontal mattress stitch is a suture technique used to close wounds.It everts skin well and spreads tension along the wound edge. [1] [2] [3] This makes it ideal for holding together fragile skin [4] as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs.
The treatment of wounds depends on whether they are external or internal. External wounds bleed outside through a skin break. They need an external wound management (read below). Internal wounds bleed inside, but some of them can pour blood outside through a natural hole. They need an internal wound management (read below).
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure. [6]
Placing and tying each stitch individually is time-consuming, but this technique keeps the wound together even if one suture fails. [1] It is simple, and relatively easy to place. A surgeon's knot or knots cross the wound perpendicularly. The knots should not be left over the wound, but placed to one side in order to avoid scarring and to make ...
The American College of Surgeons (ACS) and the Food and Drug Administration (FDA) have endorsed the adoption of blunt-tip suture needles for suturing fascia and muscle. [ 20 ] [ 23 ] [ 24 ] Hollow-bore needles pose a greater risk of injury than solid needles, but hollow-bore needle injuries are highly preventable: 25% of hollow-bore needle ...
