Laser-assisted ultrasound guidance for placing peripheral IVs during cardiac surgery
Official title: Comparison of Single Operator Laser-assisted Ultrasound-guided Peripheral Vein Cannulation With Traditional Ultrasound Guidance in Patients Receiving Cardiac Surgery
Run by Nanjing First Hospital, Nanjing Medical University · NCT07079904 · Data updated 2026-11-12
This trial will test whether a laser-assisted, single-operator ultrasound method helps clinicians get peripheral IV catheters in on the first try for adults having cardiac surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–80 years with BMI 18–30 kg/m² and ASA class 1–4 who are scheduled for cardiac surgery and can cooperate and consent would be eligible.
✕Probably not a fit
Patients with infection or hematoma at the puncture site, those unable to cooperate, those who decline participation, or those outside the specified age/BMI/ASA ranges are unlikely to receive benefit from this trial.

What this trial studies
One hundred adults scheduled for cardiac surgery were randomized 1:1 to a control group using standard ultrasound-guided short-axis out-of-plane peripheral venous catheterization with dynamic needle tip positioning or to an experimental group using a laser emitter and mechanical arm to enable single-operator laser-assisted ultrasound guidance. The trial compares first-attempt success rates of peripheral venous cannulation between the two techniques. In the control arm the operator holds and advances the needle under ultrasound visualization; in the experimental arm the probe and laser are mounted to assist single-operator alignment and insertion. The primary outcome is first-attempt catheterization success, with procedural details standardized across groups.
Why it matters
Potential benefit: If successful, the laser-assisted single-operator approach could increase first-pass IV success, reduce needle sticks and procedure time, and lower related complications.
How similar studies have gone: Conventional ultrasound guidance is well supported to improve peripheral IV success, but laser-assisted single-operator methods are relatively novel with limited published evidence to date.
