Objective: To compare the intubation time, intubation attempt and adverse events between Glidescope and McGrath laryngoscope.

Materials and Methods: A prospective randomized trial, was performed with 40 patients between the ages of 18 – 65 who had The American Society of Anesthesiologist Physical Status (ASA) I – III, and were scheduled for elective surgery. Patients were randomly allocated to one of two groups: A Glidescope group, or a McGrath group, established by using computer-generated numbers. Tracheal intubation was attempted by first year anesthetic residents, who had minimum of 3 to 6 months of experience in performing standard tracheal intubation. The operator recorded intubation time, number of attempts, complications and vital signs.

Results: Intubation time was significantly shorter for the Glidescope when compared to the McGrath laryngoscope (26.8 vs. 55.1 second, respectively, p = 0.011). The number of intubation attempts as well as the number of complications were not significantly different between the two groups.

Conclusion: Study results demonstrated that intubation time in the Glidescope group was less than the McGrath group, as performed by first year anesthetic residents, who had 3 to 6 months experience in performing standard tracheal intubations in patients with normal airways.
