Purpose: The purpose of this study was to determine
whether ultrasonography assisted internal jugular central
venous catheterization by single operator or two-operator
could improve the success rate and decrease the number of
complications compared to the traditional landmark technique.
Methods: This study was a prospective, randomized, clinical
trial conducted from July 2008 to February 2009 in an
urban Korean teaching hospital. Patients requiring central
venous access were randomized to 1 of the 3 insertion
techniques (single-operator technique, two-operator technique,
traditional landmark technique). The primary outcome
measure was cannulation success. Additional outcome
measures included number of attempts, access
times, and complications.
Results:One hundred fourteen patients were enrolled.
Thirty four of 37(91.9%) internal jugular vein catheters were
successfully inserted by single-operator technique, 34 of
39(87.2%) by two-operator technique and 22 of 38(57.9%)
by landmark technique. First attempt cannulation was successful
in 28 of 34(82.4%) using single-operator technique,
26 of 34(76.9%) using two-operator technique and 9 of
22(40.9%) using landmark technique. The median start to
venipuncture time was 138 seconds by single-operator
technique, 170 seconds by two-operator technique and 329
seconds by landmark technique. There were 19 complications
in the study, 15 in the landmark group, 2 in the singleoperator
group, and 2 in the two-operator group.
Conclusion: Real-time ultrasonography assisted internal
jugular vein catheterization has an higher success rate, is
less time consuming, and has a lower complication rate. The
single-operator technique appears to be equivalent to the
two-operator technique in success rate and procedure time.
