However, this and other studies with similar success rate, are performed in patients with general anesthesia and\u002For neuromuscular blockade, without spontaneous respiratory efforts. Critical care physicians and many other specialists frequently need to cannulate patients in special circumstances as hypovolemia, pain, anxiety, and respiratory efforts that promotes respirophasic variation in cross-sectional area, and even complete collapse of the vessel. These changes can increase the probability of posterior wall or arterial puncture, hematomas, pneumothorax, etc. Supraclavicular approach for cannulation of the subclavian vein is a method described since 1965, also giving direct access to the innominate vein, a larger vessel which is rarely collapsible regardless of volume status or respiratory efforts. Based on a previous pilot trial, in this multi-center, prospective, randomized, controlled trial, the investigators aim to compare the successfulness and safety of ultrasound-guided central venous cannulation at 3 different sites: internal jugular, subclavian, and innominate veins.",[50,56,61],{"label":51,"type":52,"description":53,"interventionNames":54},"Internal jugular vein site","ACTIVE_COMPARATOR","Ultrasound-guided central venous catheterization at internal jugular vein site",[55],"Procedure: Internal jugular vein catheterization",{"label":57,"type":52,"description":58,"interventionNames":59},"Subclavian vein site","Ultrasound-guided central venous catheterization at subclavian vein site",[60],"Procedure: Subclavian vein catheterization",{"label":62,"type":52,"description":63,"interventionNames":64},"Innominate vein site","Ultrasound-guided central venous catheterization at innominate vein site",[65],"Procedure: Innominate vein catheterization",[67,72,76],{"type":68,"name":69,"description":70,"armGroupLabels":71,"otherNames":38},"PROCEDURE","Internal jugular vein catheterization","Catheterization of internal jugular vein with real-time (in-plane) method, with neutral neck position.
