Description

Plain catgut suture is a versatile, absorbable surgical material commonly used for temporary wound closure across various medical fields. Made from purified collagen derived from the intestines of healthy ruminants, it serves effectively in procedures where suture removal is impractical, as it naturally absorbs into the body over time.

Key Features

• Absorbable Nature: Eliminates the need for removal, making it ideal for deep tissue closures.
• Monofilament Structure: Typically consists of a single twisted strand, allowing smooth passage through tissue.
• Sterility: Supplied sterile, ensuring safety in surgical environments.

Performance

Catgut sutures retain tensile strength for approximately 7 to 10 days, with complete absorption generally occurring within 60 to 90 days. This timeline can vary based on individual patient conditions and the specific surgical environment.

Handling Characteristics

Known for good handling and knot security, plain catgut suture may require additional knots due to its monofilament nature. Surgeons should be aware of its variable absorption rate and potential tissue reaction, which can differ depending on the wound environment and patient health.

Considerations

• Inflammation Potential: May cause more tissue inflammation compared to synthetic alternatives.
• Absorption Variability: Faster absorption in moist environments or in patients with certain health conditions.
• Not Ideal for Superficial Closure: Increased risk of inflammation and scarring.

Usage Recommendations

Plain catgut suture is not recommended for tissues under high tension or where long-term support is necessary. Its use has declined in favor of synthetic options in many regions, and it may be restricted in some areas due to concerns about disease transmission.

Handling and Storage

To maintain effectiveness, ensure the suture's packaging remains intact and is used within its expiry date. Proper handling is crucial to preserve sterility and performance.
