Purpose: Central venous catheterization (CVC) carries inherent risks which can be mitigated through the use of appropriate ultrasound-guidance during needle insertion. This study aims to comprehensively understand patient anatomy as it is visualized during CVC by employing a semi-automated image analysis method to track the internal jugular vein and carotid artery throughout recorded ultrasound videos.

Methods: The ultrasound visualization of 50 CVC procedures were recorded at Penn State Health Milton S.

Instructional design is the theory surrounding how learners perceive information and is prevalent in simulation-based medical education. Simulation is used for a variety of medical procedures including central venous catheterization (CVC). The dynamic haptic robotic trainer (DHRT) is a CVC teaching simulator developed to specifically focus on training the needle insertion portion of CVC.

Introduction: Performance assessment and feedback are critical factors in successful medical simulation-based training. The Dynamic Haptic Robotic Trainer (DHRT) allows residents to practice ultrasound-guided needle insertions during simulated central venous catheterization (CVC) procedures while providing detailed feedback and assessment. A study was performed to examine the effectiveness of the DHRT in training the important skills of needle tip tracking and aspiration and how these skills impact procedural complications in simulated CVC.

Gamification, or adding elements of games to training systems, has the potential to increase learner engagement and information retention. However, the use of gamification has yet to be explored in Central Venous Catheterization (CVC) trainers which teach a commonly performed medical procedure with high incidence rates. In order to combat these errors, a Dynamic Haptic Robotic Trainer (DHRT) was developed, which focuses on vessel identification and access.

Background: This study compares surgical residents' knowledge acquisition of ultrasound-guided Internal Jugular Central Venous Catheterization (US-IJCVC) between in-person and online procedural training cohorts before receiving independent in-person Dynamic Haptic Robotic Simulation training.

Methods: Three surgical residency procedural training cohorts, two in-person (N = 26) and one online (N = 14), were compared based on their performance on a 24-item US-IJCVC evaluation checklist completed by an expert physician completed after training. Pre- and post-training US-IJCVC knowledge was also compared for the online cohort.

The Dynamic Haptic Robotic Trainer (DHRT) was developed to minimize the up to 39% of adverse effects experienced by patients during Central Venous Catheterization (CVC) by standardizing CVC training, and provide automated assessments of performance. Specifically, this system was developed to replace manikin trainers that only simulate one patient anatomy and require a trained preceptor to evaluate the trainees' performance. While the DHRT system provides automated feedback, the utility of this system with real-world scenarios and expertise has yet to be thoroughly investigated.
