Methods: Seventy ASA physical status I and II patients with predicted normal airway were scheduled for thoracic surgeries with double-lumen tube intubation. They were randomly assigned to one of two groups and intubated with either the Airtraqlaryngoscope (group A, n = 35) or the GlideScope(group G, n = 35).
Results: The intubation time of group A was shorter than that of group G (36.6 ±20.2 s vs. 54.6 ±25.7 s, p = 0.002).
The Cormack-Lehanegrade (I/II/III/IV) was significantly better in group A (33/2/0/0 vs. 28/7/0/0, p = 0.042).
The mean arterial pressure and heart rate rose to higher levels during intubation with the GlideScopethan with the Airtraqlaryngoscope.
The success of the first intubation attempt and the intubation difficulty scales were comparable between the two groups. The numbers of patients who experienced postoperative sore throat were similar (6 vs. 8) in the two groups.
Conclusions: Compared with the GlideScope, the specially designed Airtraqlaryngoscope might be more suitable for double-lumen tube intubations in patients with predicted normal airway.
