Synthetic Absorbable Suture

Polyglycolic Acid (PGA) sutures are synthetic, absorbable, sterile surgical sutures made from 100% glycolide. Known for their strength, reliability, and predictable absorption rates, these medical sutures are ideal for various surgical procedures.

Composition and Structure

PGA sutures are braided multifilament sutures, providing excellent tensile strength and knot security. They are coated with biocompatible materials like polycaprolactone and calcium stearate, reducing tissue drag and making them easier to handle.

Absorption and Tensile Strength

One of the key features of PGA sutures is their absorbability. The absorption process occurs through hydrolysis, starting with a gradual loss of tensile strength followed by mass loss. These synthetic absorbable sutures retain about 75% of their initial tensile strength after two weeks, 50% after three weeks, and 25% after four weeks, with complete absorption occurring between 60 to 90 days.

Color and Specifications

Available in violet and undyed versions, PGA sutures come in various sizes (USP 8/0 to USP 2), catering to different surgical needs. The color aids in better visibility during surgery.

Sterilization

Sterilized using ethylene oxide, these medical sterile sutures are free from microbial contamination, ensuring sterility and safety.

Applications

PGA sutures are versatile, suitable for general soft tissue approximation, subcutaneous and intradermal sutures, abdominal and gastrointestinal surgeries, thoracic surgeries, orthopedic surgeries, obstetrics and gynecology, and ophthalmic surgeries.

Advantages

  1. Predictable Absorption: Ensures consistent absorption, aiding in post-operative care planning.
  2. High Tensile Strength: Provides superior tensile strength, securing tissues during healing.
  3. Minimal Tissue Reaction: Non-antigenic and non-pyrogenic, reducing inflammation and infection risk.
  4. Smooth Passage: Coating reduces tissue drag, allowing smooth passage through tissues.
  5. Versatility: Suitable for a wide range of surgical procedures.

PGLA, PDO, and PGCL Sutures

  • PGLA Sutures: Made from a copolymer of glycolide and lactide, these braided surgical sutures are absorbed within 56 to 70 days.
  • PDO Sutures: Monofilament medical sutures made from polyester, suitable for internal soft tissue approximation and pediatric cardiovascular procedures, absorbed within 180 to 210 days.
  • PGCL Sutures: Monofilament sutures designed for soft tissue approximation, absorbed within 90 to 120 days.

Conclusion

PGA, PGLA, PDO, and PGCL  (Synthetic Absorbable Suture) sutures offer reliable and effective solutions for various surgical procedures. Their predictable absorption, high tensile strength, and minimal tissue reaction make them preferred options for surgeons. Understanding these features helps healthcare professionals enhance patient outcomes.
