[On the use of ultrasound to assist central vein cannulation in Germany: a surgery of 817 departments of anesthesia].
OBJECTIVE
A survey on the current practice in using portable ultrasound machines to assist central vein cannulation was performed by sending a questionnaire to 817 departments of anaesthesiology and intensive care medicine in Germany. Also, incomplete questionnaires were included in the analysis.


RESULTS
There was a 54 % response rate. Ultrasound guidance is used by 83 (18.7 %) departments for central vein cannulation. Of these, only 7 (8.4 %) use it routinely and 43 (51.8 %) use it when faced with a difficult vein cannulation. Only one third of the departments with ultrasound facilities are using it optimally, e. g. cannulation under ultrasound guidance. Of those units not using ultrasound for central vein cannulation, 136 (37.7 %) said it was because of lack of equipment and 199 (55.1 %) did not think that it was necessary.


CONCLUSIONS
In Germany, placement of central venous catheters is usually based on anatomical landmarks. Every anaesthetist and intensive care physician should be able to place central venous catheters without an ultrasound device. Still there is not a doubt that ultrasound assistance is useful for beginners, in children, and when blind cannulation fails. Also in patients in whom catheterisation is likely to be difficult (e. g. patients, with previous central venous catheters, with abnormal anatomy etc.) Due to our data a promotion of ultrasound assistance seems urgently required.
