Memory retention of education regarding endotracheal and laryngeal tube intubation -A manikin study-

Purpose: The purpose of this study was to investigate the education retention effect of endotracheal and laryngeal tube intubation using a manikin study. Methods: The study consisted of measuring intubation time, intubation success rate, and confidence of intubation after education. The evaluation of the education was performed 2 weeks, 4 weeks, and 24 weeks after education and skill tests. The study subjects were 48 paramedic students of third and fourth grade. Results: There was no significant difference in endotracheal intubation time but the time spent performing laryngeal tube intubation significantly increased over time (p<.000). The intubation success rate of endotracheal and laryngeal tube intubation was 100% in the <TEX>24ᵗʰ</TEX> week, and there was no significant difference in time spent performing the intubation. The students' confidence in endotracheal (p<.023) and laryngeal tube intubation (p<.001) decreased significantly from the second week to the <TEX>24ᵗʰ</TEX> week. Conclusion: This study revealed that it is necessary to spend at least 24 weeks to train students endotracheal and laryngeal intubation to improve the students' confidence in performance of intubation.
