ObjectivesThe use of intraosseous (IO) access is recommended in cardiac arrest when peripheral venous access is not accessible. Various methodologies exist that are used for teaching and learning about cannulation of the IO route both in education and in research. The purpose of the present study was to compare self-efficacy in the cannulation technique for IO access through different techniques.MethodsA randomized comparative study was conducted. A total of 118 nursing students participated. The participants were randomly distributed into 2 intervention groups: chicken bone and egg. A checklist was used for data collection to evaluate the IO cannulation technique in nursing students and another to analyze self-efficacy.ResultsThe average total score of self-efficacy for all participants was 8.84 (standard deviation (SD) = 0.98). No statistically significant differences were found when comparing the total self-efficacy score and the intervention group ( U = 1604.500; z = -0.733; P = 0.463). No statistically significant differences were found between both groups for the average total score of the procedure ( U = 6916.500; z = -0.939; P = 0.348). The egg group carried out the IO cannulation procedure in a significantly less amount of time (M = 126.88, SD = 82.18) than the chicken bone group (M = 183.77, SD = 108.28), finding statistically significant differences ( U = 4983.500; z = -5.326; P < 0.001).ConclusionsUsing an egg to teach and learn about IO access could be considered a methodology that is equally effective as using a chicken bone, with the advantage of achieving IO access in a lesser amount of time.Copyright © 2023 Wolters Kluwer Health, Inc.
