Safety in training for ultrasound guided internal jugular vein CVC placement: A propensity score analysis

Central venous catheter (CVC) placement is a routine procedure but is potentially associated with severe complications. Relatively small studies investigated if the use of ultrasound is efective in bridging the skill gap between profcient and not profcient operators, while patient safety during training remains a controversial topic. The frst aim of this study was to evaluate if resident profciency afects the failure rate in CVC positioning under ultrasound guidance.
