OBJECTIVE: Training students on simulators before allowing their direct contact
with patients is well accepted. There is no clinical or manikin-based simulation
study in the literature comparing tracheal intubation with Airtraq, laryngeal
mask airway (LMA) CTrach and Macintosh laryngoscopes performed by medical
students having no prior intubation experience. METHODS: After obtaining written
informed consents, 123 participants were included in the study. The participants
were asked to intubate the manikin five times with each device randomly. After
all the participants had completed their fifth intubations, the measurements were
performed. The primary outcome variables were the first-attempt success rate and
the time for a successful intubation, while the secondary outcome variables were
to determine the scores of dental trauma, the difficulty visual analogue scale
and the optimization manoeuvres. RESULTS: The LMA CTrach group revealed a
significantly higher number of intubation attempts. The mean time for a
successful intubation was the longest in the LMA CTrach group (17.66±8.22 s,
p<0.05). Students defined the Airtraq as the easiest to use and the Macintosh
laryngoscope as the most difficult device to use and learn. Dental trauma
severity was significantly lower in the Airtraq group than in the other groups
(p<0.05), and it was found to be 0 in 81.1% in the Airtraq group. The head
extension optimization manoeuvre rate was significantly higher with the Macintosh
laryngoscope than with the Airtraq laryngoscope (p<0.05). CONCLUSION: This study,
in which different types of laryngoscopes were compared, revealed that the
Airtraq laryngoscope has advantages, such as shorter intubation duration, less
additional optimization manoeuvres, less dental trauma intensity and is easier to
learn compared with the LMA CTrach and Macintosh laryngoscopes.
