Objectives: To develop a low cost didactic protocol for venous access puncture and venous access, using an animal model.
The PERC Mentor™ is designed to train the user in percutaneous renal collecting system access puncture.
The Lariat (Sentreheart, Redwood City, CA), which is currently FDA-approved for percutaneous closure of tissue, requires both trans-septal puncture and epicardial access.
Conclusion: The proposed animal model was effective to reproduce ultrasound images similar to the human image, being possible to train puncture and venous access, showing to be a good model to be reproduced by academic uses.
Coronary angiography time was defined as the time from puncture of the access artery to completion of coronary angiography.
Puncture of the access site is not achievable in the VIST simulator instead the course participants received arterial puncture training on a dummy.
All participants had no previous experience with ultrasound-guided procedures, and medical students had no previous experience with central venous access puncture.
This means that, for blood gas analysis, arterial puncture or arterial access is necessary as the system has not yet been designed for withdrawal of blood from capillaries.
Other limiting factors were also appointed: obtaining the vesical catheterization of delay (for hourly diuresis control); rapid identification of severe sepsis; printed data record of the protocol; samples of blood culture for aerobic; and peripheral venous access puncture.
We developed a second simpler and less expensive device that functions according to the same principle and, depending on the dexterity of the surgeon, allows the same objective to be reached: to pull on a subcutaneous loop that circles an anatomic structure, in this case the platysma band, to cut it without widening the access puncture holes or cutting the skin.
When comparing both groups there was no statistical difference there was no difference in numbers of punctures in achieving access nor in complications.
