BACKGROUND Occasionally, difficulty with standard urethral catheterization is encountered. OBJECTIVE We conducted a pilot study to evaluate whether transabdominal ultrasound (TAUS) showed the tip of a urethral catheter and whether TAUS-guided catheterization with transrectal pressure is successful in male patients in whom performing standard catheterization is difficult. METHODS The eligibl...

BACKGROUND Transradial (TR) catheterization is gaining popularity due to its association with lower bleeding and access site complications, improved patient comfort, and lower costs compared to transfemoral (TF) catheterization; however, there is concern that TR catheterization may be associated with an increased risk of neurological complications. New randomized data has emerged since the publ...

An increased level of serum cardiac troponin I is a specific biomarker for myocardial injury. The objective of this study was to evaluate the changes in cardiac troponin I levels to determine myocardial injury following diagnostic cardiac catheterization. A prospective cohort study was carried out between July 1 2006 and March 31 2012 among patients who underwent diagnostic cardiac catheterizat...

Data from one patient enrolled in the early phase of the ongoing clinical trial evaluating an experimental device called the Cath-Assist are presented. The device is designed to facilitate female urethral catheterization by exposing the vulvar vestibule, isolating the urethral opening, and blocking the entrance to the vagina.

THE PHYSICIAN who desires to carry out hemodynamic or angiocardiographic studies of the left side of the heart has a large number of technics froim which to choose.1 The ideal method for such investigations should fulfill a number of criteria. First of all, the method must be relatively safe. In order to gain wide acceptaniee it must be technically simple and individuals trained in the standard...

BACKGROUND Recent guidelines from the National Institute for Clinical Excellence (NICE) recommend the use of ultrasound guidance for central venous catheterization in children. This study prospectively examined the use of ultrasound guidance for central venous catheterization in children undergoing heart surgery. METHODS One hundred and twenty-four infants and children were randomized to eith...

Fiber Optic RealShape (FORS) is a new, light-based imaging modality that allows real-time three-dimensional visualization of endovascular wires and catheters without radiation. The purpose this study to report our early experience on the feasibility limitations related FORS. Data from all consecutive patients undergoing FORS-guided procedures at single center were prospectively collected review...

A posterior ledge at the bladder neck was seen in 158 patients (107 of whom were undergoing intermittent catheterization) on a sonographic voiding cystourethrogram. In 117 patients, the ledge was 0.5 cm or longer; 66 patients were on intermittent catheterization, and 51 experienced difficulty with catheterization, including vigorous bleeding in 4. Ledges less than 0.5 cm were discovered in 41 p...

Over the past century, numerous boys born in Canada and the United States have been circumcised.1 However, this trend is changing, with neonatal circumcision being performed less commonly than in years past.2,3 Because of these historical practices, many physicians and nurses have limited experience treating patients with intact foreskins and engage in illadvised procedures such as premature fo...

T HE PATIENT who undergoes cardiac catheterization may develop an arrhythmia. It would be useful to know who is most susceptible, how hazardous the arrhythmia may be and what can be done about it. Cournand' mentioned premature contractions and runs of ventricular tachycardia as the most important complication in the procedure. Two cases were quoted in which death may have been the result of ect...
