چکیده
The urinary tract is a major site of nosocomial infections (4, 5). The leading cause of nosocomial urinary tract infections is urinary catheterization which, in turn, is the most common predisposing factor for fatal gram-negative sepsis in hospitals (6). A recent publication suggested that catheters coated with silver powder and containing a silver-plated connector could protect patients from catheter-associated bacteriuria (1). Other investigators have reported that iontophoresis of certain metals can kill bacteria in bone (2). This report describes our experimentation with iontophoretic devices designed to inhibit or kill Escherichia coli and other bacteria in fluids, such as media or urine.

Preventing Traumatic Urinary Catheter Insertion Through a Computerized Ordering System: Quasi-experimental Study From a Tertiary Academic Center
Background: Iatrogenic urethral injury is a well-known risk of urinary catheter insertion. Associated morbidities include stricture formation, catheter associated infection, risk for instrumentation, and extended length of stay. Yet, insufficient attention is paid to its prevention. Objective: This study aimed to assess the effectiveness of a computerized...

متن کاملEstablishment of a novel rat model of severe acute cholangitis
Objective(s):This study aimed to establish a novel non-binding, reversible rat model of acute cholangitis of the severe type (ACST). Materials and Methods:Twenty-six rats were randomly divided into the sham-operated group (n=13) and the ACST group (n=13). All rats were intubated with a modified catheter through the external jugular vein. The ACST model was established by ligation of the distal ...
متن کاملModel-Free Position Control for Cardiac Ablation Catheter Steering Using Electromagnetic Position Tracking and Tension Feedback
Cardiac ablation therapy is an effective minimally invasive treatment for cardiac arrhythmia. Catheter steering in the constrained environment during the procedure is considered difficult, particularly in providing accurate catheter tip positioning for ablating or for diagnosing the cardiac tissue. These difficulties and inaccuracies in the catheter tip positioning are a common reason for sever...
متن کاملSkin fold technique for central venous catheter fixation; Comparison with conventional method for postopration infections
Background: Central Venous Catheters (CVCs) are used not only as a tool to access to central venous system, but also for hemodynamic monitoring, parenteral nutrition, chemotherapy and hemodialysis. The use of CVCs is associated with some complications notably infections that are troublesome both to patient and physician. We conducted this study to examine catheter fixation with skin fold techni...
متن کاملDevelopment of a Model Depicting Optimum Performance of Liquid Catheter Sensor for Pressure Measurement
In this paper the author proposed a model that depicts not only the basic features of liquid catheter sensor but also improvement of those features. The optimum performance of the 2nd order liquid catheter sensor system depends on parameters namely natural frequency of oscillation and damping ratio and two basic features namely high frequency response and flat frequency response. As the system ...
