Abstract

STUDY OBJECTIVE:

To compare the Bullard laryngoscope (BL) with the flexible fiberoptic bronchoscope (FFB) in a cervical spine injury model, using inline stabilization.

DESIGN:

Randomized clinical trial.

SETTING:

Main operating room of a tertiary care hospital.

PATIENTS:

50 adult, ASA physical status I, II, and III patients undergoing an elective general anesthetic.

INTERVENTIONS:

Each patient's trachea was intubated with both techniques. Cricoid pressure was applied to half of the study patients.

MEASUREMENTS:

The time for laryngoscopic view and the time to intubation were recorded for each technique. The effects of cricoid pressure on laryngoscopic view and intubation time were determined.

MAIN RESULTS:

The times for laryngoscopy and intubation were longer in the FFB group than in the BL group (p < 0.004). There was a significantly lower success rate of laryngoscopy view in the FFB group in the presence of cricoid pressure (15 of 25 patients, or 60%) than either of the BL groups or the FFB no-cricoid pressure group.

CONCLUSIONS:

The BL is more reliable, quicker, and more resistant to the effects of cricoid pressure than is the FFB.
