Abstract
Purpose: The wide spread use of orotracheal intubation with rapid sequence induction has made it difficult for EMS professionals to gain experience in nasotracheal intubation (NTI) in a controlled supervised setting. The purpose of this study was to determine if a training session on NTI with a breathing manikin can be used to improve skill and comfort of EMS professionals.Methods: A prospective trial was conducted with a convenience sample of 16 emergency medical service professionals, previously trained in nasotracheal intubation techniques. For the training session a Laerdal airway manikin was modified by replacing the lungs with a bag-valve mask device, to simulate breathing with an inspiratory and expiratory phase. Following verbal instruction, and with direct supervision, each participant practiced NTI using the breathing manikin. Each participant completed a questionnaire, both before and after the training session, to determine self assessed comfort and skill level for both oral and nasal intubations (0 = lowest, 10 = highest). The pre and post intervention scores were compared using the Wilcoxon signed-rank test, £ = 0.01.
