Abstract

Central venous cannulation is a common procedure done in hospitals both in operating room (OR) and Intensive care unit (ICU) settings to provide uid, blood and blood component infusions, and to monitor central venous pressure, and administration of intravenous drugs to the patients. Various non-invasive modalities are used for the successful positioning and conrmation of correct placement of needles, guidewires, and venous catheters, including intra atrial electrocardiography (ECG) guidance, ultrasound guidance, X-ray imaging, with contrast enhanced computed tomography remaining the gold standard for conrmation of catheter placement (1).
