Single-Operator Ultrasound-Guided Central Venous Catheter Insertion Verifies Proper Tip Placement*
To evaluate whether a single-operator ultrasound-guided, right-sided, central venous catheter insertion verifies proper placement and shortens time to catheter utilization.Design:
Prospective observational study with historical controls.Setting:
Sixty-four consecutive patients undergoing ultrasound-assisted right-sided central venous catheterization compared with 92 serial historic controls who had unassisted central catheter insertion at the same sites.Interventions:
Subcostal transthoracic echocardiography during catheter insertion.Measurements and Main Results:
The primary outcome was the correct placement of the catheter tip determined by postprocedural chest radiography. The subclavian site was used in 41 patients (64%) (inserted without ultrasound guidance) in the ultrasound-assisted group and 62 (67%) in the control group, whereas the jugular vein was used in the remaining patients. The tip was accurately positioned in 59 of 68 patients (86.7%) in the ultrasound-assisted group compared with 51 of 94 (54.8%) in the control group (p < 0.001). The median time from end of the procedure to catheter utilization after chest radiography approval was 2.4 hours.Conclusions:
A single-operator ultrasound-guided central venous catheter insertion is effective in verifying proper tip placement and shortens time to catheter utilization.
