Suture definition

Effective interventions for treating a minor surgical suture site infection should definitely include one of the following choices ... 

The third reason why biocompatibility cannot be equated with inertness is that there are several, and indeed an increasing number, of applications which involve intentionally degradable materials. The two most widely quoted situations here are absorbable sutures and implantable drug delivery systems but many more circumstances where degradable scaffolds and matrices could form an essential component of a device are envisaged. If biocompatibility is predicated on inertness, then degradable materials cannot, by definition, be biocompatible. This clearly does not make sense and suggests that the concept of biocompatibility needs to be altered. 

While the data gave little reason for concern over the exposure of the general population to the field in a chlor-alkali plant, it is possible for the field to interfere with the operation of low-power electronic devices. Cardiac pacemakers are one example. The ACGIH in the same list of TLVs referred to above suggested a value of 5 G for persons with these devices. Adams reported that one company had set its own limit of 1G. Since this is a small multiple of the normal background, the rule effectively bars those with pacemakers from approaching a cell room. While not covered specifically by these rules, there should also be special concern for those who wear or carry other medical devices such as aneurysm clips, suture staples, and prostheses. These can respond to forces produced by stronger fields, but no definite limits have been set. 

The question whether silk fibroin filaments are resorbable or permanent is open to interpretation. Having a polypeptide chemical structure, silk fibroin, like any other protein, is susceptible to proteolytic degradation, and will become weaker and eventually over a period of 2 years will be totally resorbed in vzvo. However, given the definition for an absorbable suture in the United States Pharmacopeia as a material that loses most of its tensile strength within 60 days post-implantation silk can therefore be classified as a permanent biomaterial.
