THE left-to-right shunts found in small atrial or ventricular septal defects or in patent ductus arteriosus are easily demonstrated during cardiac catheterization by both rightand left-sided approaches.' Efforts to evaluate shunting due to these defects without cardiac catheterization have depended on measurements of the cardiac output curves obtained by various external counting technics.Y Bec...

Patients admitted to hospital with symptoms and signs of non-ST-segment elevation acute coronary syndromes have different risk profiles and are in need of an individualized approach that takes into consideration not only age and sex but also comorbidities such as diabetes, renal failure, hypertension, heart failure, peripheral artery disease, earlier revascularization, etc. According to evidenc...

This communication describes and discusses the results obtained in studying central and )eripheral arterial pressure pulses in man by means of retrograde aortic catheterization. The pressure pulse transformation and pulse transmission in the aorticobrachial system are presented and compared with comparable tracings reported in the dog. Several normal subjects and patients with hypertension, aor...

Central venous catheter (CVC) insertion is common in ICU practices; this can be a source of dangerous bacteremia, sepsis, multi organ failure and sometimes even death. We conducted this study to find out the rate of Catheter colonization, Catheter related blood stream infections (CRBSI), their association and microbial spectrum of CRBSI in critical care unit over 1 year period. Patients admitte...

OBJECTIVES We sought to determine the incidence of cholesterol embolization syndrome (CES) as a complication of cardiac catheterization and to identify risk factors associated with this disease. BACKGROUND Cholesterol embolization syndrome is a systemic disease caused by distal showering of cholesterol crystals after angiography, major vessel surgery, or thrombolysis. METHODS We prospectively e...

PURPOSE This narrative review summarizes the evidence derived from randomized controlled trials (RCTs) offering blinded assessment and sample size justification, in order to determine the benefits associated with adjunctive ultrasonography (US) and stimulating perineural catheters for nerve blocks. SOURCE The literature search for this review was conducted during the second week of December 2...
