“…Previous virtual reality models for vertebral canal puncture training, such as Farber’s [ 7 ], Lvquist’s [ 8 ], and Kulcsar’s [ 9 ] models, only provided students with a 3D view of the lumbar spine and a 2D view of human anatomy during the puncture process, without considering the patient’s whole body. In this study, we improved upon these models by using standard human data to reconstruct a 3D model of the lumbar spine.…”

“…The haptic component provided force feedback of the needle tip in various tissues during lumbar puncture. Lvquist [ 8 ] and Kulcsar [ 9 ] designed a virtual spinal anesthesia teaching model that offers 15 levels of adjustable force feedback, while Luca [ 10 ] developed a lumbar puncture simulator utilizing VR and a haptic device, providing more realistic haptic feedback during the needle insertion phase. However, none of these models simulate the complete human body and puncture scenario.…”

Background Intraspinal anesthesia poses significant teaching challenges and inadequate teaching resources, which ultimately limit students’ opportunities for practice. To address this issue, we aimed to develop a virtual platform for combined spinal-epidural anesthesia that merges virtual reality technology with haptic feedback technology, while assessing its educational impact and learning outcomes. Methods We utilized MIMICS, 3Ds MAX, and UNITY 3D software to perform 3D reconstruction based on lumbar CT/MRI data from a standard male volunteer. The haptic coefficients were configured on each layer by 20 experienced anesthesiologists in accordance with the Geomagic Touch X force feedback device. A total of 20 anesthesiology interns completed 30 virtual puncture training sessions. Two experienced anesthetists evaluated the efficacy of the platform and the level of mastery achieved using the Global Rating Scale (GRS) and a Checklist score, respectively. Finally, a questionnaire survey was conducted to gather feedback on the virtual platform. Results After the 10th session, the puncture time stabilized at 2.4 min. As the number of sessions increased, the Global Rating Scale (GRS) score stabilized by the 8th session, and the Checklist scores tended to stabilize by the 10th session. Results from questionnaires indicated that over half of the anesthesiology interns (70%) believed that the platform, which exhibited strong repeatability, improved their anatomical recognition and provided a strong sense of breakthrough in identifying the ligamentum flavum. The majority of them (80%) expressed satisfaction with the virtual platform. Conclusions The platform effectively facilitated the acquisition of basic and accurate puncture skills on a virtual patient.

“…In addition to some of the above studies, there have been several reviews [ 69 , 70 , 81 ] on the topic as well as instructional articles [ 82 , 83 ] that guide how to best perform specific simulation in obstetric anesthesiology. Recently specific “task trainers” for spinal anesthesia [ 84 ] and epidural anesthesia [ 85 ] have been described, albeit not perfect. Future models of these specific task trainers can build upon the experience gained and make improvements in the construction that can improve the validity of the training as compared to actual human anatomy and physiology.…”

There have been colossal technological advances in the use of simulation in anesthesiology in the past 2 decades. Over the years, the use of simulation has gone from low fidelity to high fidelity models that mimic human responses in a startlingly realistic manner, extremely life-like mannequin that breathes, generates E.K.G, and has pulses, heart sounds, and an airway that can be programmed for different degrees of obstruction. Simulation in anesthesiology is no longer a research fascination but an integral part of resident education and one of ACGME requirements for resident graduation. Simulation training has been objectively shown to increase the skill-set of anesthesiologists. Anesthesiology is leading the movement in patient safety. It is rational to assume a relationship between simulation training and patient safety. Nevertheless there has not been a demonstrable improvement in patient outcomes with simulation training. Larger prospective studies that evaluate the improvement in patient outcomes are needed to justify the integration of simulation training in resident education but ample number of studies in the past 5 years do show a definite benefit of using simulation in anesthesiology training. This paper gives a brief overview of the history and evolution of use of simulation in anesthesiology and highlights some of the more recent studies that have advanced simulation-based training.

“…A group from the National University of Singapore [5] discusses what is probably the most intricate VR simulation system of those reviewed here, and the components can be seen in In work specifically related to the procedure being simulated in this thesis, Kulcsar et al [43] discuss the different feelings that a clinician would experience during the spinal anesthesia procedure. They use an "expert perception-based approach" to select the stiffness values for the haptic rendering of the different tissues.…”

This paper presents the prototype for an augmented reality haptic simulation system with potential for spinal needle insertion training. The proposed system is composed of a torso mannequin, a MicronTracker2 optical tracking system, a PHANToM haptic device, and a graphical user interface to provide visual feedback. The system allows users to perform simulated needle insertions on a physical mannequin overlaid with an augmented reality cutaway of patient anatomy. A tissue model based on a finite-element model provides force during the insertion. The system allows for training without the need for the presence of a trained clinician or access to live patients or cadavers. A pilot user study demonstrates the potential and functionality of the system.
