[Comparison of Pentax-AWS, GlideScope Cobalt, and Macintosh laryngoscope in patients for nasotracheal intubation].

BACKGROUND

We compared the time for instrumentation in nasotracheal intubation using Pentax-AWS and Glidescope to that using the Macintosh laryngoscope in patients with normal airway.

METHODS

After local ethics board approval, 60 patients requiring dental or oral surgery were allocated randomly to Pentax-AWS, Glidescope and Macintosh groups. One experienced anesthesiologist performed nasotracheal intubation in all patients.

RESULTS

The times for instrumentation using Pentax-AWS and Glidescope, and Macintosh laryngoscope were 37 +/- 12s, 33 +/- 9s, and 30 +/- 12s, respectively. There were no differences among the three devices.

CCONCLUSIONS

When operated by experienced anesthesiologists, both Pentax-AWS and Glidescope showed similar performance for nasotracheal intubation compared with Macintosh laryngoscope in normal airway patients.
