ABSTRACT

Introduction: usually, medical students do not have a formal instruction in specific techniques like gathering sample of arterial blood. That is why an educational intervention was implemented in premedical students of Facultad de Medicina, UNAM, using a low-cost model and a video. Objective: analize if the intervention using a low-cost model promotes the technical skills in carrying out the procedure. Material and methods: quasi-experimental study with 15 premedical students using a low-cost simulator designed in CECAM and a video. The evaluation was made with a validated check-list, in three phases: pre and post educational intervention, and two weeks later in a hospitalized patient. We analized data comparing items in each phase and phases between the, square chi (χ²) and p value. Results: we found a statistical meaningful difference in one item, when comparing phase one and two; in three items in the comparison between phases two and three and in five items when comparing phases one and three. Conclusions: Implementation of educational intervention improved some aspects of gathering samples of arterial blood. This results can´t be generalized because we had few participants. Nevertheless, this was an opportunity to include low-cost simulators designed in our simulator center in educational activities focused in the improvement of technical skills to benefit patient security.
