چکیده

An accurate, rapid, and inexpensive method was developed for detecting and enumerating bacteria adherent to Foley urinary catheters based on malachite green staining of acridine orange-prestained specimens. This method has proven to be quick and reliable and will find application in quantitative studies of biomaterial-related sepsis.

Is Foley Catheter Able to Drain the Bladder Completely in the Morning for Patients in ICU?

Introduction: Foley catheters are assumed to drain the bladder completely. It is known that uncompleted drainage leads to multiple complications, such as asymptomatic bacteriuria and urinary tract infection. Methods: From 116 patients, who were admitted to intensive care unit (ICU) for more than 24 hours, were enrolled in this study. To measure the urine level in bladder in the morning before a...

Removal of adherent bacteria from catheter materials in vitro by N-acylated amino acids.

Indwelling urinary catheters may act as a reservoir of bacteria and cause urinary tract infections. Removal of the bacteria adherent to a urinary catheter should reduce the incidence of catheter-associated urinary tract infections. Using several N-acylated amino acids with combinations of four different acyl residues, we investigated their efficacy in removing adherent bacteria from catheter ma...

A Comparison Between Foley and Nelatone Urinary Catheters in Causing Urinary Tract Infection in Animal Models

BACKGROUND Urinary catheterization is one of the main measures used to treat and care for hospitalized patients. Several complications have been attributed to the presence of latex with routine Foley catheters. Therefore, some studies have recommended that Nelatone catheters be substituted for the ordinary Foley catheters to prevent these complications. OBJECTIVES This study aimed to compare ...

Novel antiseptic urinary catheters for prevention of urinary tract infections: correlation of in vivo and in vitro test results.

Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacter...

S-Nitroso-N-acetylpenicillamine (SNAP) Impregnated Silicone Foley Catheters: A Potential Biomaterial/Device To Prevent Catheter-Associated Urinary Tract Infections

Urinary Foley catheters are utilized for management of hospitalized patients and are associated with high rates of urinary tract infections (UTIs). Nitric oxide (NO) potently inhibits microbial biofilm formation, which is the primary cause of catheter associated UTIs (CAUTIs). Herein, commercial silicone Foley catheters are impregnated via a solvent swelling method with S-nitroso-N-acetyl-D-pen...
