Intérêt de l’échographie couplée à un système de guidage (GPS) dans la pose de cathéters veineux centraux

Abstract : The insertion of central venous catheter (CVC) is a common practice in anesthesia. The literature shows that ultrasound guidance allows reducing the inherent morbidity of CVC cannulation. The objective of this study is to evaluate an ultrasound system with a GPS (Guidance Positioning System) function to visualize in real time the progress and position of the needle. This is a prospective, single-center, randomized clinical trial comparing two groups of 50 adult patients undergoing an internal jugular venous cannulation for a scheduled heart surgery. GPS + group (active GPS) received a CVC cannulation with a puncture "out-of-plane" and the GPS group - (inactive GPS) received a puncture "in-plane". Randomization was performed digitally based on the experience of the operator, the expected cannulation difficulties and the location of insertion. In the GPS + group, the median cannulation time was 73 seconds [56-120] and in the GPS - group, it was 52 seconds [33-79], p <0.01. There was a significant improvement of the insertion time for operators having placed more than 4 CVC with GPS +. There was more rolling and crushing vein in the GPS + group versus GPS - group, p=0.017. The needle is more frequently in the axis of the carotid artery at the puncture in the GPS group - versus GPS + group (p <0.01) with a strong tendency to increase the risk of puncture of carotid artery in the GPS - group, p=0.056. Finally, this study shows an increase of cannulation time when the GPS function is activated but a trend towards a decrease in carotid puncture.
