Abstract ---Laryngeal
mask airway (LMA) has been shown to be an alterative method of definite
airway but its role in rescue from confined space has not been determined.
One hundred and sixty seven persons who attended the training course
of disaster medicine were enrolled as the study population. Sixty
two of them were men whereas the other 105 women. Thirty four of
the study population were medical doctors, 95 nurses, 30 emergency
medical technicians, and 8 laypersons. We arranged a workshop of
confined space medicine. The comparison of applicability between
conventional endotracheal intubation and LMA was made. Before evaluation,
every participant accepted detailed illustration and demonstration
of the skills. Every one was asked to perform airway management
for the manikins in confined space with face down, sitting position,
side position and “reverse” supine position. The success rate and
the time elapse for both endotracheal intubation and LMA application/intubation
was compared. Success rate of first LMA application is 100% for
all positions which is significantly better than those of endotracheal
intubation (85% for sitting position, P<0.01; 80% for side position,
P<0.01; 76% for face down, P<0.01; and 74% for “reverse” supine
position, P<0.001). The time elapse for first LMA application
was also significantly lower than those of endotracheal intubation
(as presented). The success rate and time elapse of first LMA intubation
and the number of trials before success was comparable to endotracheal
intubation. LMA was preferred as a choice of airway management in
confined space rescue. |
