Ultrasound (US)-guided central venous catheterization is now considered standard of care according to recent clinical evidence, at least considering jugular vein approach. Recent trials suggested that even US-guided subclavian approach could be more effective that landmark technique. However, studies comparing both sites employing US are still lacking.
We, therefore, designed a non-inferiority randomized controlled trial to compare these sites, both using US guidance, according to immediate complications following central venous catheterization.

To test the hypothesis that approaching the internal jugular vein with the needle bevel down would produce less injury to the vessel wall compared to the bevel up approach during central v...
The purpose of this study is to compare the differences in central venous catheter insertion time, success rate, and complication between the Seldinger and modified Seldinger technique for...
Total of 89 patients undergoing elective cardiac surgery will be enrolled. Right CVC insertion begins at their intersection of the cricoid cartilage level and the triangular point where t...
To evaluate the effect of a 2-stage approach to the internal jugular vein when performing a central venous catheterization compared to the traditional one stage approach on the incidence o...
The purpose of the study is to evaluate the success rate using ultrasound as guidance during central venous cannulation in pediatric cardiac surgical patients.
To report a case of successful surgical removal of a guide wire lost during central venous catheterization.
While central venous stenosis is a common consequence of protracted central venous catheter use, intracardiac device transvenous leads, and central venous instrumentation, the majority of patients who...
Apheresis treatments can be performed with peripheral venous catheters (PVC), although central venous catheters (CVC) are inserted when PVCs fail or patient with history of difficult vascular access p...
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
