Innovative Probe With Laser on Radial Artery Puncture and Catheterisation in Paediatric

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.
