In emergency services, an action of paramount importance in critically ill patients is to obtain an early vascular access for the administration of drugs, since this allows a better survival of patients. In cases where venous access can not be obtained in the first minutes, an intraosseous route must be obtained; Otherwise, the mortality of these critically ill patients amounts to almost 100%. Despite these recommendations, in Colombia the use of 7 intra-osseous access is not made due to the high costs of the devices and the lack of training of the health personnel in performing intra-osseous access. Due to the above, the objective of this study was to determine the efficacy of a low-cost device for intraosseous access. Materials and methods: quantitative approach, experimental design in simulated environment with Tarso-metatarsus chicken. Results: 99% y 100% of procedures (Insyte 14 and Illinois) were successful with both catheters final efficacy (p = 1.000) and first attempt (92% vs. 92%, p=1.000). The most frequent complication was extravasation with the Illinois device (p = 0.13). The median time for intraosseous access was significantly higher with the Insyte catheter than with the Illinois catheter, being 6.6 and 4.7 seconds respectively (p = 0.001). In contrast, no significant differences were found in the number of attempts to achieve successful intraosseous access with both devices (p = 0.56) Discussion and conclusions: There is no significant difference between Insyte 14 and Illinois catheters for intraosseous access Successful in the metatarsus tarsus of the chicken in a simulated environment. However, with the illinois catheter an intraosseous access is achieved in a shorter time than with the Insyte catheter.
