Central Venous Catheterization Using a Perfused Human Cadaveric Model: Application to Surgical Education

Perfused fresh cadavers: method for application to surgical simulation

“…Our laboratories have used this model as a surrogate for improvement in skills as currently we have not employed a direct objective measurement of skills assessment. 22,23 Comments The successful establishment of cadaveric circulation was described by Garrett 18 in 2001 in an attempt to create a model for the evaluation of vascular devices and for the simulation of vascular surgical procedures. The abstract on the patented method describes its purpose, ''for study of vascular function, research and teaching of surgical procedures and general medical education.''…”

Introducing a Fresh Cadaver Model for Ultrasound-guided Central Venous Access Training in Undergraduate Medical Education

“…One other author also describes this finding as a difficulty in the utilization of the fresh cadaver as a cannulation model. 10 Similarly, in our own attempts to infuse fluid directly into cadaver vessels, we noted local fluid extravasation and subsequent deterioration of US imaging after only a few cannulation attempts. Our model improves upon this limitation, preserves cadaver imaging, and facilitates continued use of the cadaver for other procedures such as intubation, chest tube insertion, pericardiocentesis, etc.…”

“… 9 – 11 Though cadaver models improve intravenous cannulation simulation, free flow of fluid into a cannulated post-mortem vessel leads to extravasation of fluid thereby eliminating the cadaver’s utility for other procedures. 10 In addition, extravasation of fluid results in a distortion of normal anatomy and eventual deterioration of ultrasound image quality. 11 The purpose of our investigation was to design and evaluate a life-like and reproducible training model for ultrasound-guided central venous access (USG-CVA) using a fresh cadaver.…”

A comparison of a homemade central line simulator to commercial models

“…12 Unfortunately, commercially available CVAD simulation models are costly (prices ranging from $1000-$8000 [13][14][15] ) and are often limited in their functionality and the variable anatomy frequently encountered in clinical practice. 16 In addition, little information exists to evaluate how well each model mimics human anatomy and physiology (i.e., venous versus arterial pressures of model vessels), information that is necessary to perform key portions and safety checkpoints of procedures in clinical practice. As simulation continues to gain importance in resident training, simulation centers at many institutions have started creating homemade models to allow for cost reduction while providing comparable quality to commercially available simulators.…”

“…As simulation continues to gain importance in resident training, simulation centers at many institutions have started creating homemade models to allow for cost reduction while providing comparable quality to commercially available simulators. [16][17][18][19] In addition, homemade models can be easily modified to provide the learner with challenging anatomy reflective of real-life practice. This study compared an inexpensive homemade internal jugular central line insertion simulator, developed to meet the needs of an institution-wide central line insertion training initiative, 20 to three high-end commercially available simulators; various model characteristics were also rated.…”
