Polyglactin 910 or PGLA suture is an absorbable, sterile, synthetic, braided suture. PGLA suture are indicated for soft tissue approximation and ligation. The suture’s tensile strength remains for approximately three to four weeks in tissue.
Polyglactin 910 Sutures are composed of copolymers made from 90% glycolide and 10% L-lactide. Polyglactin 910 suture is an absorbable braided synthetic fibre. It is available as a plain (uncoated) and coated suture. The coating is equal parts of a copolymer of lactide and glactide with calcium stearate. Calcium sterate is a salt of calcium and stearic acid. This mixture forms an absorbable, adherent, non-flaking lubricant ideal for suture. All of these components are water repelling which slows tissue fluid penetration and absorption into the suture. Clinical trials have shown that after two weeks, approximately 70% of Polyglactin 910 suture’s initial strength remained. Polyglactin suture are found to be non-antigenic and non-pyrogenic, eliciting only mild tissue reactivity during the absorption process. Polyglactin 910 suture are available violet and colourless.
Distinctive Characteristics Polyglactin 910 Sutures:
- Polyglactin 910 suture is coated in order to create a smoother synthetic absorbable suture that will pass through tissue readily.
- Easy tissue passage
- Precise knot placement as compared with PGA suture
- Predictable absorption by simple hydrolytic mechanism
- A decreased tendency to irritate tissue
- Greater tensile strength
- A longer absorption period
