STRUCTURAL EVALUATION OF PGA SUTURE

In the surgical field, there are many types of surgical sutures that are produced in accordance with different properties for various uses and are also used to close the wound edges or repair tissue damage. Also, surgical sutures offered for use during surgical operations should not be antigenic or pathogenic. Sutures, which are classified according to their different features, can be absorbable or non-absorbable according to the most basic classification. On the other hand, absorbable sutures are generally preferred by surgeons, except when permanent sutures are required, such as anastomoses between blood vessels.

Sutures removed from the body with the help of a doctor after wound healing are non-absorbable surgical sutures. However, sutures that can be separated in the body with the help of various tissue fluids without the need for doctor intervention are in the class of absorbable surgical sutures.

Surgical sutures can be produced in natural or synthetic ways depending on the raw material source. PGA (polyglycolic acid), also known as polyglycolide used for synthetically produced sutures, is a biodegradable polyester. PGA suture is obtained from several yarns and produced as multifilament and PGA structure. This absorbable suture is considered a homopolymer of glycolic acid (hydroxy acetic acid), introduced in 1920. In an another saying, this suture is the first synthetic and absorbable surgical suture.

In addition, PGA suture is solid in monofilament structure therefore it is produced in

braided and multifilament structure for ease of use. Also, when PGA suture is used, it does not cause excessive tissue irritation due to the minimal inflammatory reaction in the tissue. In this manner, it is encapsulated by fibrous connective tissue by showing a bactericidal effect during absorption into the tissue.

Intercalarily, the PGA suture is suitable enough for the safe use that the surgeon must provide for the patient. At the same time, PGA suture provides the conditions necessary for an ideal surgical operation. PGA suture, which has good tensile and knot strengths, provides absorption by hydrolysis. After the hydrolysis that takes place, it gradually loses its strength, so that absorption is completely ensured.

In other words, PGA suture can provide smooth tissue passage and knot tying. Also, PGA suture is prepared by Calcium Stearate and Polycaprolactone structure. There are varieties that can be produced in different lengths from 10 cm to 150 cm.

Consequently, sterilization of this surgical suture, which has an absorption period of 60-90 days, is performed with ethylene oxide. Generally, aluminum foil is used for packaging. Also, the USP range can change USP 6/0 through USP 3, in a variety of lengths.
