Indwelling femoral venous catheters were prospectively studied by ultrasonography to define the frequency and evolution of inferior vena cava (IVC) thrombosis. IVC thrombosis was identified in six of 56 catheters (54 children). Only one patient with a positive ultrasound scan had clinical signs of thrombosis. All children with IVC thrombosis had had catheters in place for over six days. It is r...

The insertion of central venous catheters through the femoral veins is not uncommon and potentially associated with risk immediate puncture-related complications severe late as infection thrombosis. As for other access devices, use a standardized protocol correct application evidence-based strategies are beneficial in reducing complications. We proposed (S.I.F.: Safe Insertion Femorally Inserte...

Most intravascular catheter-related infections are associated with central venous catheters. Technologic advances shown to reduce the risk for these infections include a catheter hub containing an iodinated alcohol solution, short-term chlorhexidine-silver sulfadiazine- impregnated catheters, minocycline-rifampin-impregnated catheters, and chlorhexidine- impregnated sponge dressings. Nontechnol...

OBJECTIVE To retrospectively study the results obtained with the implementation of totally implantable catheters in patients undergoing chemotherapy. METHODS 815 totally implantable catheters placed in 793 patients undergoing chemotherapy regimen, preferably using the right cephalic vein. We evaluated early and late complications. RESULTS The retrospective analysis showed an average duratio...

OBJECTIVES This study presents a cost-effectiveness analysis comparing hydrophilic coated to uncoated catheters for patients performing urinary intermittent catheterisation. A national budget impact analysis is also included to evaluate the impact of intermittent catheterisation for management of bladder dysfunctions over a period of 5 years. DESIGN A Markov model (lifetime horizon, 1 year cy...

Intravascular catheters and urinary catheters are the 2 most commonly inserted medical devices in the United States, and they are likewise the two most common causes of nosocomially acquired bloodstream infection. Biofilm formation on the surfaces of indwelling catheters is central to the pathogenesis of infection of both types of catheters. The cornerstone to any preventive strategy of intrava...

Following routine coronary arteriography, surface irregularities and thrombogenesis of the inner and outer wall of six Ducor polyurethane and six RPX polyethylene coronary catheters were studied by scanning electron microscopy. Polyurethane catheters had rough and highly irregular external and internal surfaces. All catheters showed adherent thrombi on their external surface. The internal surf...

Deposition of thrombotic material on catheters was observed following more than 50% of 93 diagnostic catheterizations. The incidence of deposition of thrombotic material on catheters remaining in the body for more than 1 day was 100%. Polyethylene and siliconized polyurethane catheters were less thrombogenic than Teflon end-occluded catheters. A definite time relationship between the thrombus f...

BACKGROUND Urinary tract infections (UTIs) account for 30% to 40% of nosocomial infections resulting in morbidity, mortality, and increased length of hospital stay. OBJECTIVE To assess the efficacy of a silver-alloy, hydrogel-coated latex urinary catheter for the prevention of nosocomial catheter-associated UTIs. METHODS A 12-month randomized crossover trial compared rates of nosocomial cat...
