Suture Material

What is Chromic Catgut?

Surgical Gut suture is an absorbable sterile surgical suture composed of purified connective tissue (mostly collagen) derived from the serosal layer of beef (bovine) intestines.

The chromic gut contains a chromic salt solution to delay absorption. Surgical gut suture meets all requirements established by the United States Pharmacopeia (U.S.P.) for absorbable surgical sutures.

Surgical gut (Plain and Chromic) is indicated for use in general, soft tissue approximation and/or ligation, including use in ophthalmic procedures.

How It Works

Actions in Tissue

Understanding how Chromic Catgut behaves once placed in the body

When Surgical Gut Suture is placed in tissue, a moderate tissue inflammation occurs characteristic of foreign body response. This is followed by a loss of tensile strength and suture mass, as the proteolytic enzymatic digestive process dissolves the surgical gut. This process continues until the suture is completely absorbed.

Many variable factors may affect the rate of absorption. The following are major factors which can influence tensile strength loss and absorption rates:

Chromic Absorption Rate

Chromic gut is 100 percent absorbed in 60 to 90 days, providing a predictable and extended absorption window compared to plain gut.

Effect of Infection

Surgical gut is absorbed more rapidly in infected tissue than in non-infected tissue. Clinical condition at the wound site directly influences the absorption timeline.

Tissue Site Dependency

Surgical gut absorbs more rapidly in tissue where increased levels of proteolytic enzymes are present, as in the secretions exhibited in the stomach, cervix, and vagina.

DemeTech's Chromic Catgut suture is an absorbable, sterile, surgical suture composed of highly purified connective tissue (mostly collagen), available in Brown. It is treated with chromium salt solution to resist body enzymes, thereby prolonging the absorption time to over 90 days. This chromic covering not only prolongs the strand's integrity but also minimises tissue irritation, causing less internal reaction. Higher percentages of collagen allow for superior tensile strength, longer absorption times, and lower reactions in vivo.

Highest Quality Collagen

DemeTech manufactures its Chromic Catgut sutures with the highest quality collagen, maintaining a composition of 97%–98% pure collagen.

Chromic Salt Coverage

Covered in chromic salt to prolong integrity, minimise tissue reactivity, and minimise the chance of adverse reactions in the body.

Tensile Strength Retention

Tensile strength is retained for up to 14 days, and sometimes as long as 21 days, providing adequate wound support during the critical healing period.

Smooth Tissue Passage

Allows for smooth passage through tissue with minimal drag, reducing trauma at the suture line and improving surgical efficiency.

Easy Knot Tying

Easy knot tying characteristics provide the surgeon with reliable, secure closure that holds through the wound healing phase.

Advanced Chromicizing Technology

DemeTech's new technology of chromicising strands minimises the possibility of fraying and maximises the potential and integrity of the Chromic Catgut suture.

Usage

Indications

Do not resterilize. Discard open unused sutures.
Store at cool room temperature. Avoid prolonged exposure to elevated temperatures.
As with any foreign body, prolonged contact with salt solutions such as those found in the urinary or biliary tracts may result in calculus formation.
Users should be familiar with surgical procedures involving absorbable sutures before use, as risk of wound dehiscence may vary with site of application.
Acceptable surgical practice should be followed with respect to drainage and closure of contaminated or infected wounds.
The use of this suture may be inappropriate in patients with conditions which may delay wound healing.
Use of supplemental non-absorbable sutures should be considered for sites undergoing expansion, stretching, or distension.

Safety

Precautions

Under some circumstances, notably orthopedic procedures, immobilisation by external support may be employed at the discretion of the surgeon.
Skin sutures which must remain in place longer than 7 days may cause localised irritation and should be removed as indicated.
Care should be taken to avoid damage from handling. Avoid crushing or crimping due to application of surgical instruments such as forceps or needle holders.
Adequate knot security requires the accepted surgical technique of flat, square ties, with additional throws as warranted by surgical circumstance.
Certain patients may be hypersensitive to collagen or chromium and might exhibit an immunological reaction resulting in inflammation, tissue granulation, or fibrosis.
Adverse effects may include wound dehiscence, failure to provide wound support in closure of the abdomen, chest, or joints, and pain, edema, and erythema at the wound site.
