Most recent guidelines suggest central venous access must be performed with real-time ultrasound guidance, and the most recommended site for cannulation is internal jugular vein (IJV); however, it is recognized that evidence for other sites is, at present, limited. Besides, guidelines does not account for patients with small vein cross-sectional area and/or respirophasic collapse, which can make the procedure more difficult or even impossible. The investigators aim to compare three different insertion sites for central venous access, with real-time ultrasound guidance
Patients who need central venous catheterization, and have respirophasic variation in cross-sectional area of jugular veins
Less than 18 years-old
Patients with previous failed attempts with non-ultrasound guided technique
Non-resolved pneumothorax/hemothorax at enrollment
Refusal to sign informed consent
