ALTERATION OF CATHETERS.

Risk of colonization of central venous catheters: catheters for total parenteral nutrition vs other catheters.

BACKGROUND Infected central venous catheters cause morbidity and mortality. OBJECTIVE To compare the risk for colonization of central venous catheters used for total parenteral nutrition with that of catheters used for other purposes. METHODS Retrospective review of prospectively acquired data on 260 patients with a stay in a surgical intensive care unit longer than 3 days. Single-lumen cat...

Complications of Peripheral Intravenous Catheters During 72 Hours After Insertion

Introduction: Peripheral Intravenous catheterization is the most commonly used invasive treatment method in patients admitted to the hospitals, but it has some complications. The indwell time of catheter is one of the factors associated with the occurrence of complications, especially phlebitis. In spite of the instructions for replacing the catheters after 72 hours, sometimes the complications...

Flexibility of Diagnostic Catheters

The diagnostic catheter is an intravascular catheter, which is usually used to inject the contrast media and/or fluids to the body. The cardiovascular system contains tight angulations in the tortuous vessels which can cause device failure. In this study the flexibility of one diagnostic catheter was investigated according to the Food and Drug Administration’s recommendation. The catheter was b...

Thrombogenicity of angiographic catheters.

A radioimmunoassay for measurement of canine fibrinopeptide A, which provides a quantitative index of thrombin action on fibrinogen, has been applied to measurements of the thrombogenicity of five angiographic catheters commercially available and presently in clinical use. Examples of thin-walled polyethylene, wired polyethylene, Teflon, polyurethane, and woven Dacron catheters were characteriz...
