Target Sign vs Palpation for Radial Arterial Line Placement

NCT02557828 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 260

No results posted yet for this study

Summary

Invasive blood pressure monitoring is achieved by cannulating an artery and transducing the pressure. During arterial cannulation the artery can be located by palpation, but use of ultrasound has increased the success rate of cannulation. A new ultrasound technique for vascular cannulation (dynamic needle tip positioning) has been described. Investigators aim to compare this technique to the palpation technique for arterial cannulation. Investigators hypothesize that the use of this novel ultrasound technique will result in a higher first attempt success rate and overall success compared to palpation.

Investigators plan to enroll 310 patients in this study. The participants in the study will have been deemed by the attending anesthesiologist to require a radial arterial line for the operation and thus the research protocol will not involve a deviation from the standard of care.
