Simulation is a popular and effective training modality in medical education across a variety of domains. Central venous catheterization (CVC) is commonly undertaken by trainees, and carries significant risk for patient harm when carried out incorrectly. Multiple studies have evaluated the efficacy of simulation-based training programs, in comparison with traditional training modalities, on learner and patient outcomes. In this review, we discuss relevant adult learning principles that support simulation-based CVC training, review the literature on simulation-based CVC training, and highlight the use of simulation-based CVC training programs at various institutions.

“…Sugarfree gelatin and psyllium are less prone to mold formation compared with their sugar-based counterparts. Similar models have been described as using gelatin, [2] silicone, [3] ballistics gel, [4] wax, [5,6] and tofu. [7] We believe that, for very low-resource environments, this is a highly functional, low-cost phantom using readily available products and low start-up costs.…”

Homemade Cardiac and Vein Cannulation Ultrasound Phantoms for Trauma Management Training in Resource-Limited Settings

Ultrasound has become an essential skill for trauma management in resource-limited areas. Prohibitive costs of commercial ultrasound phantoms limit the abilities of many hospitals to adequately train health-care providers. We assessed the utility of homemade phantoms in a wartime setting. Thirty physicians and technicians enrolled in a medical training course, sponsored by the Syrian American Medical Society (SAMS). Ultrasound simulation models were created onsite by using psyllium, gelatin, a hotel coffee maker, and Pyrex dishes. Lamb hearts were used to teach visual diagnosis and subsequent drainage of pericardial effusions. Penrose drains were used to teach vein identification and cannulation under dynamic ultrasound guidance. Two phantoms with a total of 14 penrose drains were created, serving 30 health-care providers. Feedback from participants was positive and within one month of the course, two cases of pericardial tamponade were diagnosed and surgically treated in the largest trauma hospital operated by SAMS. Context : In resource-limited environments, ultrasound phantoms (models) are cost-prohibitive. Aims : We assessed the utility of homemade phantoms in a resource-limited wartime setting to train Syrian physicians and technicians in vein cannulation and limited cardiac ultrasonography. Settings and Design : Thirty physicians and technicians enrolled in a medical training course, sponsored by SAMS. Methods : Ultrasound simulation models were created onsite by using psyllium, gelatin, a hotel coffee maker, and Pyrex dishes. Lamb hearts were used to teach visual diagnosis and subsequent drainage of pericardial effusions. Penrose drains were used to teach vein identification and cannulation under dynamic ultrasound guidance. Two phantoms with a total of 14 penrose drains were created, serving 30 health-care providers. Statistical Analysis Used : N/A Results : Feedback from participants was positive and within one month of the course, two cases of pericardial tamponade were diagnosed and surgically treated in the largest trauma hospital operated by SAMS. Conclusions : Homemade ultrasound phantoms are a promising cost-effective means for meeting an educational gap in ultrasound training, particularly for resource-limited hospitals and possibly more broadly in residency education.

“…Low-fidelity models, such as gelatin- or animal tissue-based models, are less anatomically accurate and require preparation but have low cost and high portability. Despite these limitations, when compared to high-fidelity models, low-fidelity models have demonstrated comparable, if not superior, quality [ 20 , 21 ].…”

“…Gelatin-based low-fidelity simulation models are not only low-cost and portable, but also have the added benefits of durability and bacterial resistance when compared to animal tissue-based models. In addition, gelatin-based simulation models can also be easily modified to provide the learner with models that reflect inter-patient anatomic variation, providing additional procedural experience[ 21 ]. As a result, low-fidelity gelatin-based simulation models are able to overcome multiple time and resource limitations by providing a variety of high-quality models at the point of care.…”

Ultrasound (US)-guided central venous catheter (CVC) insertion is a procedure that carries the risk of significant complications. Simulation provides a safe learning atmosphere, but most CVC simulators are not available outside of simulation centers. To explore longitudinal trends in US-guided CVC insertion competency in internal medicine (IM) interns, we studied the use of a low-fidelity, gelatin-based, US-guided CVC insertion simulation model combined with a simulation curriculum. This prospective observational study of IM interns was performed over the course of one academic year. Interns (n = 56) underwent model-based, US-guided procedure simulation training program and a repeated training course prior to their intensive care unit (ICU) rotation. CVC insertion competency at different timepoints was recorded. Survey data about intern experience and attitudes were also collected. Out of the 56 interns initially trained, 40 were included in the final analysis. Across all outcomes, interns experienced skill atrophy between initial training and the beginning of their ICU month. However, by the end of the month, there was a significant improvement in competency as compared to initial procedural training, which then waned by the end of the intern year. Attitudes toward the model were generally positive and self-reported confidence improved throughout the course of the year and correlated with objective measures of competency. Over the course of their intern year, which included simulation training using a gelatin-based model, interns demonstrated consistent competency trends. The use of a gelatin-based CVC insertion simulation model warrants further study as an adjunctive aid to existing simulation training.

A comparison of a homemade central line simulator to commercial models

Abstract: Our data suggest that an inexpensive, homemade central line model is as good or better than commercially available models. Areas for potential improvement within models include the ultrasound image and ability to appropriately measure manometry of accessed vessels.
