Airtraq is easier to learn
The learning curve for laryngoscopy: Airtraq versus Macintosh laryngoscopes
J Anesthesia, M. Baciarello, University of Parma, Italy
Purpose. This prospective study was designed to compare learning curves for laryngoscopy with the Airtraq or Macintosh laryngoscopes in patients under general anesthesia.
Methods. Ten medical students with no prior experience in airway management were recruited. Each student performed laryngoscopy with either device on ten consecutive patients.
Conclusion: Students achieved higher success rates using the Airtraq laryngoscope during early training on live patients.
Teaching tracheal intubation: Airtraq is superior to Macintosh laryngoscope
BMC Medical Education, Hong Zhao, Peking University People’s Hospital, Beijing, China
Method: Twenty-six medical students in the 6th year participated in this trial. Each of the students intubated 3 patients with each laryngoscope respectively. Macintosh (n = 75) or Airtraq (n =74).
Results:
- Intubation success rate was significantly higher in Airtraq group (87.8% vs. 66.7%, P < 0.05).
- Duration of glottis exposure was significantly shorter in Airtraq group (50 ± 19 s vs. 81 ± 27 s, P < 0.001).
- A grade I Cormack and Lehane glottic view was obtained in 94.6% of patients in the Airtraq group versus 32% of patients in the Macintosh group (P <0.001).
- Duration of intubation in Airtraq group was significantly shorter (68 ± 21 s vs. 96 ± 22 s, P < 0.05).
CONCLUSION: Airtraq laryngoscope is easier to master for novice personnel with a higher intubation success rate and shorter intubation duration compared with the Macintosh laryngoscope.
