What is a synthetic suture?

What is a synthetic suture?

Absorbable synthetic sutures are composed of chemical polymers that are absorbed by hydrolysis and cause a lesser degree of tissue reaction after placement.

What is Polysorb?

Polysorb™ sutures are composed of Lactomer™ glycolide/lactide copolymer, which is a synthetic polyester composed of glycolide and lactide (derived from glycolic and lactic acids). They are prepared by coating the suture with a mixture of a caprolactone/glycolide copolymer and calcium stearoyl lactylate.

What are synthetic absorbable suture?

synthetic absorbable suture an absorbable suture produced from strands of polymers; the most commonly used materials are polyglactin 910 (Vicryl) and polyglycolic acid (Dexon); the latter is more rapidly absorbed.

What is Dacron suture?

Dacron is a polymer of ethylene glycol and terephthalic acid. A number of experimental studies have demonstrated that it has good qualities for suture material and synthetic grafts. 1-5. It has greater tensile strength than silk or cotton, does not lose strength upon sterilization, and causes minimal tissue reaction.

Is Polysorb and Vicryl suture difference?

Results: Polysorb had the highest linear tensile strength but also the fastest loss of function following tissue implantation, whereas Vicryl showed the slowest loss of function. Similar results were obtained with regard to the knot-breaking strength.

What is Polyglyconate suture?

The Polyglycolic Acid suture is an absorbable braided multifilament surgical suture with synthetic coating, of greater tensile strength, a longer period of absorption and which results in very little inflammatory reaction. It is degraded by Chemical Hydrolysis, and is absorbed and metabolized by the human body.

What is PDS suture?

PDS (polydioxanone suture), a new synthetic absorbable suture, was used in 21 patients undergoing cataract surgery. It still retains 25% of its tensile strength at 42 days but absorption takes 130-180 days.

Which suturing technique should I use?

Here are some guidelines for the inexperienced to help you decide on which suturing technique to use. Interrupted sutures are sutures that are placed and tied individually. For the inexperienced this is the preferred technique due to its ability to close a wound cleanly and securely.

How are sutures made in wound care?

The wound edge is everted with a skin hook and then an absorbable suture is introduced at the subcutaneous level and brought back out at dermal level on the same side of the wound. See figure 10.

What is included in the suturing kit?

The basic suturing kit includes: The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups:

How do you use a suture knot?

The long end of the suture is wrapped around the tip of the closed needle holder twice before grasping the short end of the suture with the needle holder. The first double knot is then pulled gently tight.
