Study objective: To evaluate the effectiveness of the CTrach Laryngeal Mask Airway (LMA) when used electively.
Design: Retrospective analysis.
Setting: Operating room of an academic hospital.
Measurements: Data from 126 patients who were electively intubated with the CTrach LMA over a 16-month period were reviewed. Each patient's weight, height, ASA physical status classification, Mallampati score, thyromental distance, and cervical spine range of motion were recorded.
Main results: Successful ventilation was achieved in 100% of patients, while successful intubation was achieved in 89.7% of patients. The most common reason for failure to intubate was poor airway visualization and the inability to appropriately position the device anterior to the vocal cords.
Conclusions: The major advantage of the CTrach LMA is that it is the only device that allows airway visualization during patient ventilation; however, it does not have 100% success with intubation.
