Polydioxanone(PDO) is a sterile absorbable synthetic monofilament suture composed of polyester polydioxanone. The PDO Absorbable Suture has been proven to be non-antigenic and non-pyrogenic.
There are two main characteristics of the PDO Absorbable Sutures which are the tensile strength retention and secondly the absorption rate. The PDO Absorbable Suture is available dyed in violet from sizes: USP 9/0-USP 2.
Compliance with the requirements Of EP
Lower incidence of infection and trauma due to smooth surface
Smooth tissue passage
Predictable loss and higher strength compared to Catgut
PDO sutures are generally preferred where the combination of an absorbable suture and longer wound support is desired. PDO is generally used in general surgery, including pediatric surgery, ophthalmic surgery, gastrointestinal surgery, gynaecology, plastic surgery, urology and orthopaedics.
It is not used for adult cardiovascular tissue, neurology and prosthetic devices.
The results of in vitro studies of PDO suture indicate that 70% of its original strength remains after 4 weeks and 50% of its original strength remains after 6 weeks
PDO suture complete absorption takes 6-7 months.
