Unidirectional 8-MHz continuous wave Doppler equipment can facilitate catheterization of the internal jugular vein
W. Schregel, H. Straub and G. Singbartl
In a prospective study, 8-MHz unidirectional, continuous wave Doppler
equipment was shown to improve the success rate of internal jugular vein
catheterization. In the first series of 100 patients, punctures were
randomly divided into two groups, via the anterior or posterior route,
representing the standard technique. The second series of 50 patients
underwent punctures guided by the Doppler technique. The Doppler route was
successful in 48 test punctures with 47 catheter placements. Via the
anterior route, 14 of 50 test punctures were positive, with 11 catheter
placements; for the posterior route, test punctures were positive in 25 of
50 cases, with 18 catheter placements. With the Doppler technique, it
should be possible to increase the rate of successful catheterization of
the internal jugular vein while reducing complications.
