To avoid the use of live anaesthetized animals in surgical training, particularly in training on procedures that must simulate the living human in terms of ability of bleeding, and liquid filling of vessels to practice vascular and microsurgical procedures. We have developed a new method using human cadavers for surgical training by connecting the vessels of the cadaveric specimen to colored liquid reservoirs and using a pump to provide pulsating pressure transmitted to the vessels. This method provides a condition that simulates live surgery in terms of bleeding, pulsation, and fluid filling of the vascular tree, being an excellent alternative model. It can be applied to the whole cadaver or to a particular cadaveric parts (head, arm, leg…) or to an isolated organ (heart, liver, kidney,…) and can be applied in the same manner to animal cadaveric specimens for veterinary surgical training instead of using live healthy animals. It is distinctive and of a great practical value for training on a wide range of surgical procedures. Utilizing this technique will eliminate, and forever the use of live anaesthetized healthy animals for surgical training.
