Usefulness of a low-cost simulation model for teaching internal manual aortic compression. A survey-based mannequin evaluation.

Abstract

To evaluate the users' opinion on internal manual aortic compression (IMAC) training, using a low-cost simulation model. An educational strategy was designed to teach IMAC, which included: (1) guided reading of educational material and viewing an explanatory video of IMAC; (2) an introductory lecture with the anatomical considerations, documentation of the cessation of femoral arterial flow during IMAC, and real clinical cases in which this procedure was used; and (3) simulated practice of IMAC with a new low-cost manikin. The educational strategy was applied during three postpartum hemorrhage workshops in three Latin American countries and the opinions of the participants were measured with a survey. Almost all of the participants in the IMAC workshop, including the simulation with the low-cost mannikin, highlighted the usefulness of the strategy (scores of 4/5 and 5/5 on the Likert scale) and would recommend it to colleagues. We present a low-cost simulation model for IMAC as the basis of an educational strategy perceived as very useful by most participants. The execution of this strategy in other populations and its impact on postpartum hemorrhage management should be evaluated in further studies.
