Ultrasound-image Guided Versus Doppler Guided Versus Palpation Technique for Arterial Cannulation in Adults
NCT01276171 · View on ClinicalTrials.gov ↗
Study Summary
Radial arterial cannulation is a common invasive procedure for real-time measurement of arterial blood pressure. Placement of the arterial catheter using conventional palpation is often relatively easy and quick, but this is not always true. A relatively new method for direct visualization of the artery is the use of two-dimensional ultrasound. This technique allows cannulation of the artery to take place under real-time visualization and may increase the success rate of first time pass of the needle. Another technique utilizing Doppler has also proven to be effective in cannulating the radial artery. This technique utilizes changes in acoustic pitch as the probe passes directly over the artery. The primary objective of this study is to compare the first attempt success rate for radial artery cannulation among the palpation, Doppler and U/S guided technique when applied by trainees. Secondary outcomes include: success rate within 5 minutes, successful, number of attempts required, and correlation between success rate and operator experience for successful cannulation of the radial artery.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01276171
The ClinicalTrials.gov registry entry for NCT01276171 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 749 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Iowa, which has 156 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Anesthesia appearing as the primary indexed condition, and to 3 interventions — of which Ultrasound is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01276171 reports 1 study location spanning 1 distinct geographic area — top geographies include Iowa. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
