BOB Ped Surg 2023 - Dr. Maria Velayos, IBEROAMERICANA - Presentation

Good morning. My name is Maria Valallos. I am a resident in the pediatric surgery in La Paz Hospital in Madrid. First of all, thank you for the opportunity to present our work here. I am going to talk about our initial training model in micro surgery in rats. The preparation of surgical specialists is complicated. and increase the difficult to change in the learning model, change in the distribution of case about the new technologies and change in the residency. Therefore, in education, there are forced to look for ways to complement it with other learning methods such as experimental models, which are a tool for the acquisition of technical skill such as sensitivity, precision, and common in surgical movement. But one of the big problem is the lack of standardization. The objectives of our work were to show our initial model based training in micro surgery to serve as a model of guide for others and analyze the learning curve during the process including the operative times and the professional outcome of the process. Our experimentation program is composed of an initial theoretical part and several practical models divided into three levels. First, basic mode that includes activities in non living material. Second, transition mode, include a rat artery and finally experimentation mode with live animals in the in this case, rats. We decide to focus or describe and analyzing the experimental model in rats. Decision we carry out in December 2021 in a room of an experimental laboratory with microscope and micro surgical material. By December 6th, on rats, were the 60% were male with mean weight of 400 grams. As a series of basic procedure we selected, tail bay cannulation, bubblerization and anastomosis, this section section anastomosis of cava and aorta. The surgical time and functional outcome was measuring all of them. A total nine session we carry out. The mean time of the act procedure is shown in the upper part of the table and in the lower part, we put the functional result where 100% of the tail cannulation and bubble anastomosis were successful compared to 89% of the atic anastomosis. And 66% of the cava anastomosis. This procedure is the most difficult. This was very focused, we observed, how the times were shortening from the serve attempts onwards, step for the cava anastomosis which was similar to the nine sessions. So we interpreted that this was the most difficult to obtain professional success and improve the times. In conclusion, the proposed training model showed that the products were adequate for the training progression. The creation and continued development of training core protocols on experimental animals will improve the technique. Micro surgical training will benefit from standard programs to optimize outcomes and other select three years principles. At the bottom of the slide, you can see code that will take you to videos about the teams. Thank you so much.
