Bottom Line: The Airtraq laryngoscope and the GlideScope are commonly used in many airway scenarios.The Cormack-Lehane grade (I/II/III/IV) was significantly better in group A (33/2/0/0 vs. 28/7/0/0, p = 0.042).The numbers of patients who experienced postoperative sore throat were similar (6 vs. 8) in the two groups.

ABSTRACT

Background: The Airtraq laryngoscope and the GlideScope are commonly used in many airway scenarios. However, their features have not been fully described for double-lumen tube intubation. A prospective randomized study was designed to compare their intubation performances in thoracic surgery patients.

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 Airtraq laryngoscope (group A, n = 35) or the GlideScope (group G, n = 35). Airway assessments were performed prior to anesthesia, and all patients were induced with a standard anesthetic regimen. The Cormack-Lehane grades were initially evaluated with a Macintosh laryngoscope and subsequently with the group-specific laryngoscope before intubation. Intubation time was recorded as the primary outcome. The Cormack-Lehane grade, the success of the first intubation attempt, the intubation difficulty scales and ease of tube advancement were noted. Hemodynamic variables during intubation and incidence of post-operative sore throat were documented as well.

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-Lehane grade (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 GlideScope than with the Airtraq laryngoscope. 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 Airtraq laryngoscope might be more suitable for double-lumen tube intubations in patients with predicted normal airway.

Hemodynamics changes during the intubation periods with the two laryngoscopes. Mean arterial pressure (MAP, upper) and heart rate (lower) are shown. The values increase at the time of intubation and return to baseline at 3 min after intubation with the exception of the GlideScope group. The data are presented as means ± SDs. Baseline: prior to intubation; Intubation: at the time of intubation; 3 min: 3 min after intubation. *P < 0.05, compared with baseline; ΔP < 0.01, for the comparison between two groups.

Mentions: The mean arterial pressures and heart rates increased during the period of intubation in both groups. Significant differences were found between two groups on the levels of increase in blood pressures and heart rates. In addition, both blood pressure and heart rate returned to baseline after intubation in group A, while in group G, they kept in higher levels 3 min after intubation (Figure 3). The incidences of sore throat were comparable between group A (6, 17%) and group G (8, 23%) after 24 h of postoperative followed-up.Figure 3
