BACKGROUND Epidural analgesia is commonly used to provide several types of pain relief. Although this technique has been widely used with many advantages, currently the complications appear to be increasing. Especially, inadvertent intravascular cannulation and intravascular local anesthetic administration can lead to fatal consequences. METHODS Data was collected on 296 patients undergoing e...

PURPOSE The Magnetic resonance imaging (MRI) is an emerging technology for catheter-based imaging and interventions. Real-time MRI is a promising methodfor overcoming catheter and physiologic motion for intravascular imaging. METHODS All imaging was performed on a 1.5 T Signa MRI scanner with high-speed gradients. Multiple catheter coils were designed and constructed, including low-profile, s...

introduction:the assessment of intravascular volume in severely traumatized patients or patients admitted in icu is very essential. at present the accurate method for estimating the intravascular volume requirement is by measuring the cvp which is an invasive method. the measurement of ivc diameter by ultrasound has been suggested as an easily available and simple method for measuring the intra...

Acinetobacter is an aerobic, non-fermentative gramnegative bacillus, which is widespread in nature (1). Acinetobacter has been recognized as a pathogen which plays a significant role in the colonization and infection in immunocompromised patients. Acinetobacter has been implicated in a variety of nosocomial infections, including bacteremia, urinary tract infection, and ventilator-associated pne...

We demonstrate the feasibility of a time-resolved fluorescence spectroscopy (TRFS) technique for intraluminal investigation of arterial vessel composition under intravascular ultrasound (IVUS) guidance. A prototype 1.8-mm (5.4 Fr) catheter combining a side-viewing optical fiber (SVOF) and an IVUS catheter was constructed and tested with in vitro vessel phantoms. The prototype catheter can locat...

PURPOSE Evaluation of the technical success rate and complications when retrieving dislocated intravascular foreign bodies. MATERIAL AND METHODS Between 1999 and 2015 38 patients (21 female; 17 male; Age: 17 - 92; Average 54.3 years) underwent an extraction of intravascular dislocated foreign bodies, which were not lost during a radiological intervention. The extracted material included 29 po...

Intravascular near-infrared fluorescence (NIRF) imaging offers a new approach for characterizing atherosclerotic plaque, but random catheter positioning within the vessel lumen results in variable light attenuation and can yield inaccurate measurements. We hypothesized that NIRF measurements could be corrected for variable light attenuation through blood by tracking the location of the NIRF cat...

INTRODUCTION This study had two objectives: 1) to determine the clinical and microbiological profiles of patients developing intravascular catheter-related local (localized catheter colonization and exit site) and systemic infections and their predisposing factors; 2) to study the antibiotic sensitivity patterns of the organisms isolated. METHODOLOGY This case-control study was conducted over...
