Endotracheal Intubation by Paramedics Using Neodymium Magnet and Modified Stylet in Simulated Difficult Airway: A Prospective, Randomized, Crossover Manikin Study. | LitMetric

AI Article Synopsis

  • The study investigates a new method for endotracheal intubation (ETI) using a modified stylet with a magnet to improve success and efficiency.
  • Emergency medical technicians performed intubation on a manikin, comparing the new magnetic technique (METI) with traditional methods (CETI) in terms of success rate, time, and difficulty.
  • Results showed both methods had a 100% success rate, but METI was quicker and less difficult than CETI, suggesting the magnet-assisted approach could be a promising development for ETI practices.

Article Abstract

Background: The present study evaluates the success and efficacy of endotracheal intubation (ETI) using a modified intubation stylet and a magnet system to direct the stylet into the trachea. The system was developed by the researchers in an attempt to increase the success and efficacy of ETI.

Methods: ETI procedures were performed on an airway management manikin by emergency medical technicians with at least four years of experience in ETI. The technicians used a stylet modified with an iron ball affixed to the tip and a neodymium magnet, designed specifically for the study. The intention was to guide the endotracheal tube into the trachea at the level of the thyroid and cricoid cartilages on the manikin with the aid of the modified stylet and the magnetic force of the neodymium magnet. The success rate, completion time, and degree of difficulty of two procedures were compared: magnetic endotracheal intubation (METI) and classic ETI (CETI).

Results: The success rate was 100% in both groups. The mean completion times for the METI and CETI procedures were 18.31 ± 2.46 s and 20.01 ± 1.95 s, respectively. There were significant differences in completion time and degree of difficulty between the METI and CETI procedures (both =0.001).

Conclusions: We found the use of a neodymium magnet and modified stylet to be an effective method to guide the endotracheal tube into the trachea. The present study may provide a basis for future studies.
