What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to improve how medical residents learn to place central venous catheters, which are tubes inserted into large veins. The researchers seek to determine if advanced robotic training devices, such as the Dynamic Haptic Robotic Trainer (DHRT) or the Advanced Dynamic Haptic Robotic Trainer (DHRT+), enhance residents' performance and reduce complications like infections. Medical residents at selected hospitals will train with either the basic or advanced version of a robotic device. Patients undergoing central venous catheterization might participate in this trial as residents practice under supervision. As an unphased trial, this study focuses on enhancing medical training and offers patients the opportunity to contribute to improved healthcare practices.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that these training devices are safe for medical residents?

Research has shown that the Dynamic Haptic Robotic Trainer (DHRT) and its advanced version, DHRT+, effectively teach medical residents how to insert central venous catheters. These devices allow residents to practice crucial steps safely before working on real patients. By simulating the procedure, they help residents build confidence and skills in a controlled environment.

As DHRT and DHRT+ are training tools not used directly on patients, no negative effects have been reported. They provide a safe practice method, reducing the chance of complications during actual procedures. These devices aim to lower the risk of issues like infections and mechanical problems when residents perform the procedure on patients.

In summary, the safety of DHRT and DHRT+ stems from their role as educational tools. No direct risks to patients have been reported from their use in training medical professionals. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the DHRT Training Devices for Central Venous Catheter Placement Skills because they offer a cutting-edge approach to medical training. Unlike traditional methods that rely on static mannequins or observational learning, these devices use advanced haptic technology to provide a dynamic, hands-on experience. The Advanced Dynamic Haptic Robotic Trainer (DHRT+) and the Dynamic Haptic Robotic Trainer (DHRT) give medical residents realistic feedback and a safe environment to develop their skills. This innovative training could lead to better outcomes and increased confidence in real clinical settings.

What evidence suggests that these training devices are effective for improving central venous catheter placement skills?

This trial will compare the effectiveness of the Dynamic Haptic Robotic Trainer (DHRT) and the Advanced Dynamic Haptic Robotic Trainer (DHRT+) in enhancing medical residents' ability to perform central venous catheterization. Research has shown that both devices significantly improve skills by providing a realistic and controlled practice environment, which reduces complications during the procedure. The DHRT+ proves particularly effective, boosting residents' confidence and skills more than the DHRT alone. One study confirmed that residents trained with these devices experienced fewer mechanical problems and infections when performing the procedure on real patients. This evidence suggests that using DHRT and DHRT+ in training can lead to safer and more successful central venous catheter placements. ^{1 2 3 6 7}

Published Research Related to This Trial

In a study involving 163 residents practicing simulated central venous catheterization, higher rates of needle tip tracking (over 40%) and aspiration (over 80%) significantly increased the likelihood of successful venous access, reducing procedural complications.

The study highlighted that while proper tip tracking and aspiration are crucial for success, residents struggled to improve their tip tracking skills without specific feedback, indicating the importance of detailed performance assessment in training.

The Dynamic Haptic Robotic Trainer (DHRT) is an effective simulator for teaching central venous catheterization (CVC), specifically focusing on the needle insertion technique.

Implementing a hands-on instructional walkthrough improved the learnability of the DHRT, suggesting that interactive training methods can enhance the performance of learners in medical procedures.

Training surgical residents on a Dynamic Haptic Robotic Trainer (DHRT) for ultrasound-guided Internal Jugular Central Venous Catheterization (US-IJCVC) effectively transfers skills to clinical practice, as shown by comparable performance to those trained on traditional manikins.

There were no significant differences in procedural outcomes between DHRT-trained and manikin-trained residents, indicating that DHRT training is a valid and effective method for teaching this critical skill.

The Dynamic Haptic Robotic Training (DHRT) system effectively distinguished between expert and novice performance in Central Venous Catheterization (CVC) by measuring key metrics such as time to complete the insertion and standard deviation of deviations (SDoD).

Novice surgeons demonstrated significant improvement in their skills, as evidenced by reduced path length and time to complete the insertion after training with the DHRT system, indicating its potential for enhancing surgical training outcomes.
