To provide clinicians with an evidence-based overview of all topics related to ultrasound vascular access. An international evidence-based consensus provided definitions and recommendations. Medical literature on ultrasound vascular access was reviewed from January 1985 to October 2010. The GRADE and the GRADE-RAND methods were utilised to develop(More)
Stereological analysis has been coupled with transmission electron microscope (TEM) orientation mapping to investigate the grain boundary character distribution in nanocrystalline copper thin films. The use of the nanosized (<5 nm) beam in the TEM for collecting spot diffraction patterns renders an order of magnitude improvement in spatial resolution(More)
Use of peripherally inserted central catheters (PICCs) has grown substantially in recent years. Increasing use has led to the realization that PICCs are associated with important complications, including thrombosis and infection. Moreover, some PICCs may not be placed for clinically valid reasons. Defining appropriate indications for insertion, maintenance,(More)
Crit Care Med 2012 Vol. 40, No. 10 DOI: 10.1097/CCM.0b013e31825f78c3 allows measurement of changes in the perfusion of the renal cortical microcirculation which, experimentally, parallel changes in clearance measurements of renal plasma flow in humans (5). To conclude, we believe that CPCMRI is a powerful technique that complements both standard and(More)
