Description

Plain catgut suture is a versatile, absorbable suture material commonly used in various surgical procedures for effective wound closure and soft tissue approximation. Made from purified collagen, it is derived from the intestines of healthy ruminants, providing a natural solution for surgical needs.

Key Features

• Absorbable Material: As an absorbable suture, it gradually breaks down within the body, eliminating the need for removal. This feature makes it particularly suitable for internal tissues where long-term presence is unnecessary.
• Natural Composition: Composed of collagen, it integrates well with bodily tissues, minimizing adverse reactions.
• Monofilament Structure: The smooth, monofilament-like structure ensures ease of handling, reducing tissue trauma during application.

Surgical Applications

Plain catgut suture is widely used across various medical fields, including:

• General surgery
• Obstetrics and gynecology
• Urology
• Gastrointestinal procedures
• Orthopedics
• Ophthalmology

Its versatility makes it a preferred choice in situations where temporary support is sufficient and suture removal is not feasible.

Handling and Performance

• Tensile Strength: Retains tensile strength for approximately 7 to 20 days, depending on the tissue environment.
• Absorption Timeline: Typically absorbed within 30 to 90 days, with the rate influenced by factors such as enzymatic activity and infection presence.
• Knot Security: Known for reliable knot security and flexibility, enhancing surgical outcomes.

Storage and Precautions

• Sterility: Supplied in a sterile condition, it should remain sterile until use to prevent infection.
• Storage Conditions: Recommended to store in a cool, dry place away from direct sunlight.

Limitations

While plain catgut suture offers numerous benefits, it is not suitable for:

• Cardiovascular surgeries
• Neurological tissue approximation

Additionally, its use has declined in favor of synthetic alternatives in some regions due to concerns about disease transmission and regulatory restrictions.

Conclusion

Plain catgut suture remains a valuable tool in the surgical field, offering natural absorbability and effective performance in appropriate applications. Its continued use requires careful consideration of patient and procedural factors to ensure optimal results.
