Objective: To determine the level of the technical skills development of the medical student in performing surgical sutures through a virtual teaching model. Methods: A retrospective, descriptive and longitudinal study was carried out that evaluated some skills of 24 undergraduate medical students, without prior surgery knowledge to perform surgical sutures (simple and crossed interrupted suture) through virtual teaching of the course of surgical technique (virtual classrooms, synchronous videoconferences, inanimate and ex vivo simulation models and telementoring). Results: In relation to the simple interrupted suture, there was a significant improvement in the OSATS (objective structured assessment of technical skills) from 6 ± 0.28 to 28 ± 2.6 as well as the rubric of the finished suture from 5 ± 0.28 to 24 ± 1.5 and a decrease in the time to perform the suture from 44 ± 13 second...

Objective: To evaluate the skills achieved by the undergraduate medical student in performing an open appendectomy and purse string in the simulation model created, to evaluate the degree of satisfaction of its use and to determine its costs. Method: Pre-experimental, prospective and longitudinal study. The skills achieved by 24 undergraduate medical students in performing an open appendectomy and purse string in the simulator were evaluated using the OSATS (Objective Structured Assessment of Technical Skills) through virtual teaching. A survey was conducted to the students to evaluate the simulator and its costs were determined. Results: There was a significant increase in the OSATS of the skills achieved, from 7 (pre-test) to 26 ± 5.71 points (final post-test) (p = 0.0001) and reduction in the operative time from 12 ± 3.81 minutes (first post-test) to 8 ± 2.02 minutes (final post-te...
