Acute supraglottitis in adults: what's the optimal airway intervention?

OBJECTIVES

To validate the Friedman stage and define the proper timing for airway intervention in adult cases of acute supraglottitis, we evaluated the clinical courses and management of adult patients.

METHODS

202 adult patients with acute supraglottitis were included in this study. The diagnosis of supraglottitis was established by flexible nasolaryngoscopic examination. Friedman stages were classified in each patient. In this study, the first three days of serial nasolaryngoscopic findings for each patient were evaluated.

RESULTS

All patients were treated successfully with only conservative methods. There were no significant differences between patients with Friedman stages I or II/III. Among the patients that had serial nasolaryngoscopic findings, only one patient presented with progressive swelling of the epiglottis, and there were no cases of persistent swelling.

CONCLUSION

The airway intervention threshold should be raised from Friedman stages II-III. And, airway intervention should not be needed if patients are tolerant of their respiratory discomfort.
