Laser-assisted ultrasound guidance for placing peripheral IVs during cardiac surgery

Comparison of Single Operator Laser-assisted Ultrasound-guided Peripheral Vein Cannulation With Traditional Ultrasound Guidance in Patients Receiving Cardiac Surgery

Not applicable Interventional Nanjing First Hospital, Nanjing Medical University · NCT07079904

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
