PGLA LACTIC is a synthetic, absorbable, braided surgical thread, made of a poly(glycolide-co-L-lactide) (90/10). The thread is coated with a mixture of poly(glycolide-co-L-lactide) (30/70) and calcium stearate. The coating increases smoothness of the thread surface enabling precise tying of the suture and a tight and sure knot. It also reduces tissue traumatisation.
The PGLA LACTIC thread may be natural (beige) or purple (coloured with C. I. Solvent Violet 13 colorant). With the time, the resistance to stretch is lowering and the final absorption as a result of hydrolysis takes place. % of the original Breaking Strength Retention:
- 75% after 14 days from implantation,
- 50 % after 21 days from implantation,
- 25 % after 28 days from implantation.
The absorption is complete after – 60-70 days from implantation.
Atraumatic combinations of the threads are manufactured in different lengths and sizes and are furnished with single or double stainless steel needles of different type and size. The product is also available without the needle as a ligature. The unit package and the label are beige. The PGLA LACTIC surgical threads meet the requirements of the Polish and European Pharmacopoeia.
INDICATIONS AND USE
Combinations of PGLA LACTIC threads and needles depend on the type and size of a patient’s wounds, the area, the surgical techniques, the surgeon’s experience and the patient’s condition. The threads are mainly recommended for soft tissues (subcutaneous tissues, mucous membrane) and/or tying off tissues, which do not require prolonged action of the ligature). Surgical use of the thread includes: general, paediatric and plastic surgery, urology, orthopaedics, gynaecology and obstetrics. They are also used in dental surgery and for joining mucous membrane in mouth, as well as eye surgery, for joining peripheral nerves and blood vessels.
CONTRAINDICATIONSThe absorbable PGLA LACTIC thread should not be applied, when prolonged joining of tissues is necessary. The suture may cause gentle tissue reaction during absorption. Any significant contradictions for PGLA LACTIC have been described. Basically not used in cardiac and vascular surgery. When using PGLA LACTIC sutures, worse absorption in case of older, malnourished and weakened people as well as patients in a condition, which might extend the process of tissue healing should be taken into account. Individual allergic responses to the suture may occur.
If the package is broken, the suture may not be used. The package content should not be sterilised again. In closed and not impaired packages, sterility is guaranteed by the expiry date. The PGLA LACTIC suture is a disposable material for one patient only. Unused thread, after the sterile bag is open, may not be used later. Do not reuse as the suture is not sterile or non-pyrogenic anymore and may be biologically infected.
STORAGEThe sutures should be stored in an original package, in dry and airy places, free from humidity and direct sunlight, at the temperature below 25 °C. Do not use after expiry date.
