Innovative Probe With Laser on Radial Artery Puncture and Catheterisation in Paediatric
China408 participantsStarted 2026-02-11
Plain-language summary
During prolonged major surgical procedures in paediatric, significant fluctuations in vital signs occur. To ensure real-time, precise monitoring of haemodynamic parameters such as blood pressure and heart rate for maintaining intraoperative safety, radial artery catheterisation remains the most conventional monitoring method for such operations. Ultrasound-guided radial artery puncture has gained increasing favour among clinicians over traditional palpation and blind techniques due to its visualisation and real-time advantages, with its benefits becoming increasingly evident. Nevertheless, this technique still carries a relatively high failure rate. This study proposes the 'laser-assisted T-shaped three-dimensional ultrasound localisation technique' for paediatric radial artery puncture and catheterisation. This aims to enhance puncture success rates, reduce the need for repeated attempts, lower complication incidence, safeguard the patient's life during surgery, and improve the quality of medical services.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* The paediatric patient's family fully understands and voluntarily participates in this study, having signed the informed consent form.
* Paediatric patients undergoing critical surgery requiring radial artery puncture and catheterisation for continuous blood pressure monitoring are selected.
* ASA physical status classification of I-IV.
* Age ≤ 24 months, gender not restricted.
Exclusion Criteria:
* Paediatric patients who have undergone radial artery puncture within the past month.
* Paediatric patients with abnormal development of the radial or ulnar arteries, peripheral vascular disease at the radial puncture site, congenital heart disease, or haemorrhagic or cardiogenic shock.
* Paediatric patients with wounds, infections, or haematomas near the radial puncture site.
* Ultrasound imaging demonstrating inadequate collateral circulation or a negative Allen test.
* Cases where the paediatric patient's guardian refuses to sign the informed consent form for study participation.
* Other circumstances deemed unsuitable for trial participation by the investigator.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
