Learning and Memorization of Radial Artery Puncture and Catheterization Guided by Ultrasound Midline
Conditions
Brief summary
This study aims to investigate medical students' mastery of radial artery puncture and catheterization skills guided by the midline on ultrasound when using scenario simulation combined with intermittent training, and to compare this approach with traditional teaching methods.
Detailed description
With the continuous advancement of modern anesthesiology and critical care medicine, arterial monitoring has become an integral part of clinical anesthesia management. During anesthesia, functions such as arterial blood pressure monitoring and arterial blood gas analysis enable real-time surveillance of vital signs, playing a crucial role particularly in the anesthesia management and postoperative monitoring of high-risk patients. The radial artery, being a superficial and easily accessible vessel, has become one of the commonly used arterial puncture sites in clinical practice. Furthermore, this technique is a mandatory skill for residents in standardized training programs within anesthesiology departments. However, as an invasive procedure, it demands high proficiency from the operator and carries significant risks of complications such as infection, hematoma, thrombosis, and arterial spasm. Radial artery catheterization poses a challenge for residents, making it essential to establish a straightforward and clear teaching strategy.The success rate of ultrasound-guided radial artery puncture is influenced by operator experience, particularly among resident physicians. Although ultrasound with a midline feature can assist in puncture, catheter placement remains challenging, and the effectiveness of their mastery requires further study. Current training programs exhibit gaps, with clinical settings predominantly relying on intensive learning sessions that yield poor skill retention. Interval learning, despite its advantages, is underutilized. Given the clinical workload constraints of residents, sustained practice after intensive training is challenging. Therefore, designing and implementing an intermittent training program for ultrasound-guided radial artery catheterization is highly significant. This approach aims to combine the strengths of both intensive and intermittent training to enhance residents' skills, reduce complications, ensure patient safety, and provide departments with a new, effective training method.
Interventions
OTHERIntermittent Retraining
Through basic skills training and testing, it was confirmed that all trainees had mastered the procedural steps for radial artery puncture and catheterization guided by ultrasound midline imaging. Testing also validated the students' proficiency in performing this procedure. The intermittent retraining group underwent repeated training at fixed intervals, performing the same tasks daily on days 3, 7, and 14.
OTHERNon-interval retraining
Through basic skills training and testing, it was confirmed that all trainees had mastered the procedural steps for radial artery puncture and catheterization guided by ultrasound midline imaging. Testing also validated the students' proficiency in performing this procedure. The non-intermittent retraining group did not repeat the same tasks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| First Attempt Catheterization Success Rate | The fourteenth day after the unified training | The percentage of cases where the operator successfully punctures the target vessel (specifically the radial artery in my study) on the first attempt and advances the catheter to the desired position. This process requires no additional puncture attempts, catheter adjustments, or encounters procedural failure (such as unsuccessful vessel entry, guidewire/catheter entanglement, abnormal positioning, or immediate complications like hematoma formation). |
| First-Attempt Radial Artery Catheterization Success Rate | The 14th day after training | First-Attempt Success Rate of Radial Artery Catheterization Guided by Ultrasound Median Line |
| Incidence of complications | The 14th day after training | Incidence of Complications in Radial Artery Puncture and Catheterization Guided by Ultrasound Midline |
