Background:
Ultrasound-guided vascular access has been increasingly used in clinical practice with studies supporting improved insertion success and reduced complications. To meet the needs of various vascular access applications, ultrasound systems have been evolving with specific features. This study evaluated the safety and performance of a recently developed portable ultrasound system with needle tracking technology for peripheral intravenous catheterization.
Methods:
The prospective observational clinical study was conducted at one US medical center between November 2025 and January 2026. Eligible participants requiring peripheral intravenous access underwent ultrasound-guided insertion for peripheral intravenous catheterization. Primary endpoints included successful visualization of target vasculature and successful intravenous access. Safety was assessed by the incidence of device-related adverse events. Descriptive statistics and exact binomial confidence intervals were calculated.
Results:
A total of 149 subjects were enrolled, including 17 pediatric (1-17 years) and 132 adult (≥18 years) patients. Ninety-six of these patients presented with at least one DIVA risk factor, including no visible veins, no palpable veins, a history of difficult IV access, IV drug use, or a BMI ≥ 30 kg/m2. With ultrasound guidance, visualization of vasculature was achieved in all participants (100%; 95% CI: 97.6%, 100.0%), and the overall catheter insertion success rate was 100% (95% CI: 97.6%, 100.0%). The mean number of attempts to achieve successful vascular access was 1.05±0.25. While the overall first-attempt success rate was 95.3%, a rate of 100% was observed in pediatric patients and 94.7% in adult patients. For the adults with any DIVA risk factor, the first-attempt success rate was 92.0%. There were no device-related adverse events observed in the study.
Conclusion:
The portable ultrasound system was associated with high first-attempt insertion success and high vascular visualization for peripheral intravenous access with no adverse events. The portable ultrasound system can be successfully used for bedside vascular access in a real-world environment.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
