The chromic catgut absorbable suture is a medical procedure used to close a wound after it has been made. It consists of two parts: the suture itself, usually silk thread, and tying it in place with an instrument. The process is completed by cutting off excess material from the suture’s end with blunt scissors, leaving enough for the knot to be tied securely.
Sutures may be placed on several parts of the body such as skull fractures or surgical wounds during surgery. They are not meant to remain permanently in place unless they become embedded into tissue; if they are removed prematurely they may cause infection or bleeding.
What are sutures made of?
Absorbable chromic catgut sutures are mainly made of materials such as nylon and polypropylene, but may sometimes be made from silk or animal intestines. The choice of material depends on factors including an individual body’s ability to react to the suture material and any allergies that person might have.
Surgical knots are usually tied by surgeons using a suture passer or forceps; however, they can also be tied manually by the surgeon in special circumstances. A knot always leaves behind a closed loop that may get caught on surgical instruments inside the patient's body after surgery, so surgeons try to choose knots that are smooth and have small amounts of extra thread. Knots can be divided into categories by the type of Borromean rings they are able to form. The end result of tying a knot is a balanced or unbalanced knot, which is determined by the direction of the pull when tying it. Suture knots must be able to withstand high amounts of pulling force without breaking.
The suture material is chosen based on its properties and its compatibility with tissue and organs, such as skin or bone. Suture materials are chosen for their ability to dissolve in body fluids, resist degradation from bodily fluids and mechanical stress, and ensure satisfactory wound healing. Suture materials are also chosen for their visibility and for the aesthetics of the suture. Common types of suture materials include surgical monofilament nylon, braided nylon, and silk.
Wound sutures can be removed by a physician using blunt scissor or forceps, or removed by self-removal or removal by a home care provider. Some wound sutures dissolve in bodily fluid, while others must be cut off, either in the doctor’s office or at home. The time it takes for a suture to dissolve is usually determined by its composition and placement. The surgeon will determine when the time has come to remove a particular suture by following its progress as it dissolves.
Benefits
- Sutures may be left in place indefinitely, whereas stitches cannot
- Sutures can be removed by cutting them out of a wound
- Sutures usually cause less discomfort than stitches
disadvantages
- It may be difficult to remove them if they are left too long
- It is more difficult to tell how much suture has been pulled apart by pulling it apart - Suture knots can become embedded into surrounding tissues and organs. Suture removal requires a surgeon to cut the knot out of the incision very carefully using sharp instruments or a scissors. Not all surgeons are experienced with this procedure and some complications arise from attempting to remove a suture too soon.
conclusion
The most common stitches are bone wound anchors, which are used to keep the bone ends together after the anchor has been placed between them. These are made up of two parts: a part that fits into a hole drilled through one bone (usually by a drill called an awl), and a longer piece that extends through the first bone and is attached to a second bone with surgical cement. The anchor is usually left in place permanently except in certain circumstances when it can be removed at a later date.
