Abstract
Background

Macintosh laryngoscopes are widely used for endotracheal intubation training of medical students and paramedics whereas there are studies in the literature that supports videolaryngoscopes are superior in endotracheal intubation training. Our aim is to compare the endotracheal intubation time and success rates of videolaryngoscopes and Macintosh laryngoscopes during endotracheal intubation training and to determine the endotracheal intubation performance of the students when they have to use an endotracheal intubation device other than they have used during their education.

Methods

Endotracheal intubation was performed on a human manikin owing a standard respiratory tract by Macintosh laryngoscopes and C-MAC® videolaryngoscope (Karl Storz, Tuttligen, Germany). Eighty paramedic students were randomly allocated to four groups. At the first week of the study 10 endotracheal intubation trials were performed where, Group-MM and Group-MV used Macintosh laryngoscopes; Group-VV and Group-VM used videolaryngoscopes. Four weeks later all groups performed another 10 endotracheal intubation trial where Macintosh laryngoscopes was used in Group-MM and Group-VM and videolaryngoscopes used in Group-VV and Group-MV.

Results

Success rates increased in the last 10 endotracheal intubation attempt in groups MM, VV and MV (p = 0.011; p = 0.021, p = 0.290 respectively) whereas a decrease was observed in group-VM (p = 0.008).

Conclusions

The success rate of endotracheal intubation decreases in paramedic students who used VL during endotracheal intubation education and had to use Macintosh laryngoscopes later. Therefore we believe that solely videolaryngoscopes is not enough in endotracheal intubation training programs.

Resumo
Justificativa

Os laringoscópios Macintosh são amplamente utilizados para o treinamento de estudantes de medicina e paramédicos em intubação endotraqueal; contudo, há mais estudos na literatura que apoiam os videolaringoscópios no treinamento de intubação endotraqueal. Nosso objetivo foi comparar o tempo de intubação endotraqueal e as taxas de sucesso de videolaringoscópios e laringoscópios Macintosh durante o treinamento de intubação endotraqueal e determinar o desempenho da intubação endotraqueal dos alunos quando precisam usar um dispositivo de intubação endotraqueal diferente daquele que usaram durante seu treinamento.

Métodos

A intubação endotraqueal foi realizada em modelo humano com trato respiratório padrão usando laringoscópios Macintosh e videolaringoscópio C-MAC® (Karl Storz, Tuttligen, Alemanha). Oitenta estudantes paramédicos foram randomicamente alocados em quatro grupos. Na primeira semana do estudo, 10 tentativas de intubação endotraqueal foram realizadas, nas quais o Grupo-MM e Grupo-MV utilizaram laringoscópios Macintosh e o Grupo-VV e Grupo-VM utilizaram videolaringoscópios. Quatro semanas depois, todos os grupos realizaram mais 10 tentativas de intubação endotraqueal, nas quais laringoscópios Macintosh foram utilizados pelo Grupo-MM e Grupo-VM e videolaringoscópios pelo Grupo VV e Grupo-MV.

Resultados

As taxas de sucesso aumentaram nas últimas 10 tentativas de intubação endotraqueal nos grupos MM, VV e MV (p = 0,011; p = 0,021, p = 0,290, respectivamente), enquanto uma redução foi observada no Grupo-VM (p = 0,008).

Conclusões

A taxa de sucesso da intubação endotraqueal diminuiu nos estudantes paramédicos que utilizaram VL durante o treinamento em intubação endotraqueal e precisaram usar laringoscópios Macintosh posteriormente. Portanto, acreditamos que o uso isolado de videolaringoscópios não é suficiente em programas de treinamento de intubação endotraqueal.
