(2013) Ultrasound-guided central venous cannulation is superior to quick-look ultrasound and landmark methods among inexperienced operators: a prospective randomized study. Intensive Care Medicine. September 12th. [epub ahead of print].

Abstract:

OBJECTIVE: Quick-look ultrasound with a skin mark (UM) has been frequently used for central vein cannulation. The aim of this study is to compare this method with landmark (LM) and ultrasound-guided (UG) cannulation of jugular and femoral veins by inexperienced operators.

DESIGN: Prospective randomized single-center study.

SETTING: A medical intensive care unit (ICU) of a university medical center.

PATIENTS: Patients requiring jugular or femoral central cannula placement.

INTERVENTION: Each inexperienced resident randomly inserted a central venous line using the UM, LM or UG technique.

MEASUREMENTS AND FINDINGS: The primary outcome was the success rate, and secondary outcomes were the placement time, number of attempts, mechanical complication rate, and catheter colonization rate. A total of 118 patients were randomly assigned to the three groups. The mean age of patients included in the study was 65 ± 15 years, and the mean Simplified Acute Physiology Score 2 (SAPS2) was 57 ± 20. The success rate was higher in the UG group than in the LM and UM groups (100, 74, and 73 %, respectively; p = 0.01). The total number of mechanical complications was higher in the LM and UM groups than in the UG group (24 and 36 versus 0 %, respectively; p = 0.01). The number of attempts and the access time were higher in the LM group than in the UG group, but not compared with the UM group. No difference in terms of catheter colonization was observed between the three groups.

CONCLUSIONS: Ultrasound-guided cannulation of the internal jugular or femoral vein by inexperienced residents appears to be more reliable than the LM or UM methods and was associated with a lower mechanical complication rate among ICU patients.
