Report the procedural complications of internal jugular vein (IJV) catheter insertion in infants and children and discuss how to prevent them. ⋯ The IJV catheterization was feasible in infants and children. To reduce the risk of complications, the procedure should be performed or supervised by staff anesthesiologists; inserting the needle, guidewire, dilator, and the catheter too far should be avoided. It is now commonly accepted that all central venous cannulations should be performed under ultrasound guidance, especially in children.

International policy statements from the US and the UK recommend real-time ultrasound guidance (USG) for placement of central venous catheters (CVCs) to improve patient safety. The evidence to support USG for the internal jugular (IJ) route is unequivocal; however, there is conflicting data on the effectiveness of USG in visualization of the subclavian vein (SCV). This study sought to determine whether body mass index (BMI) or clavicle shape affected SCV visualization with USG. ⋯ Higher BMI and the presence of a flat clavicle limit the ability to visualize the SCV. These findings may help account for why USG for placement of SCV CVCs is less utilized. However, patients with a low/normal BMI and protuberant clavicle may benefit from USG when attempting SCV CVCs.

Tunneled hemodialysis catheter-related bloodstream infections: a prospective multicenter cohort study from Spain.
Catheter-related bloodstream infections (CRBSI) are common among patients undergoing long-term hemodialysis (HD) worldwide. The aim of this study was look into the incidence, epidemiology, and risk factors for CRBSI in four medical centers and Spanish dialysis facilities following a common protocol for insertion and management of tunneled hemodialysis catheters (THCs). ⋯ Although some factors, such as vascular cause of renal disease and previous THC medical history, have been related to the onset of tunneled catheter-related bloodstream infections, the incidence of these bacteremia, mainly produced by gram-positive coccus, is low among hemodialysis patients and the mortality rate is not high.

To identify clinically important risk factors associated with upper extremity venous thrombosis following peripherally inserted central venous catheters (PICC). ⋯ In multivariate analysis, trauma, renal failure, left-sided catheters, basilic placement, TPN, and infusion with antibiotics, specifically vancomycin, were significant risk factors for UEVT associated with PICC insertion. Prophylaxis with low molecular weight heparin, unfractionated heparin or use of warfarin did not prevent the development of venous thrombosis in patients with PICCs. Length of hospital stay and cost are markedly increased in patients who develop PICC-associated upper extremity venous thrombosis.

To report our initial results of venovenous ECMO placement of a novel bicaval dual lumen catheter in six consecutive patients with severe respiratory failure. ⋯ Our initial results suggest that single cannulation dual lumen venovenous ECMO catheter placement can be performed successfully and safely in an Interventional Radiology setting. The technique reported is feasible, easy to use, and the outcome seems to be comparable to other performing implanting specialties.
