Aggressiveness intravascular catheters due to the high hardness of the materials from which they are made

In city hospital conducted a study of the dynamics of the state of the body parts of the patients in the place of installation they of intravascular plastic catheters made of polyurethane, silicone and Teflon. It is shown that proper installation of high-quality catheters often causes local inflammation of the soft tissues regardless of the material from which the catheters. It was found that all modern high-quality intravascular catheters have overly pronounced mechanical traumatic action that underlies the characteristic local inflammation of the vascular wall and surrounding tissues. Invited to consider this “catheter” as an independent disease iatrogenic disease. It is established that catheter disease occurs due to excessive mechanical damage to the soft tissue by the catheter due to the high roughness of its outer surface, excessive acuteness and high elasticity of its working end that is mechanically scratch a vessel wall inside the vessel. It is established that ceteris paribus the severity of the aggressive actions of the local quality of intravascular catheters in the venous wall depends on the type of polymeric material from which the catheters...
