The application of HC visual laryngoscope as a visualization teaching method for the standardized training of endotracheal intubation in emergency department / 中华急诊医学杂志

ABSTRACT

Objective To investigate the feasibility and effect of visualization teaching method using HC visual laryngoscope for the standardized training of endotracheal intubation in emergency department.Methods Forty standard-trainee doctors were divided into two groups randomly.20 standard-trainee doctors in team N were taught using the conventional teaching method of emergency medicine for the standardized training of endotracheal intubation,and the other 20 standard-trainee doctors in team HC were taught by visualization teaching method using HC visual laryngoscope.After 1 month training,comparisons of the success rate of tracheal intubation in airway management simulator,the time consumed for intubation and the number of attempt on successful intubation cases,and the satisfaction score with the teaching mode scored by standard-trainee doctors between the two groups were done.Results The one-attempt success rate and the success rate of tracheal intubation in airway management simulator by the standard-trainee doctors in group HC were significantly higher than those in group N (40％ vs.10％,85％ vs.55％),while the number of attempt and the time consumed for successful intubation were significantly less than those in group N[(1.65±0.61) vs.(2.27±0.66),(79.00±8.35) s vs.(89.36±12.03) s).The satisfaction score with this teaching mode and teaching effect of standard-trainee doctors in group HC were significantly higher than those in group N (8.10±0.74 vs.6.55±1.05,8.15±0.80 vs.6.85±0.91).Conclusions The visualization teaching method with application of HC visual laryngoscope for standardized training of endotracheal intubation in emergency department could improve the success rate and efficiency of tracheal intubation in airway management simulator for standard-trainee doctors,and this teaching method may be better than the conventional teaching method on teaching mode presenting some feasibility.
