Abstract
The positioning of various central venous catheters in newborns including very thin silastic catheters has been checked by sonography. Even the very thin silastic catheters are easily detectable owing to their strong echoes. Diverse malpositions are presented, including non-central positioning detected by sonography. The frequency of control radiographs could be reduced.
