Comparing NoSAS, STOP-Bang, and Berlin scores for predicting difficult airway

AI simplified

Abstract

In a study of 420 patients, 19.8% were identified as having difficult mask ventilation and 24.0% as having difficult intubation.

  • The showed greater predictive power for difficult mask ventilation and difficult intubation compared to the STOP-Bang and Berlin scoring systems.
  • A cut-off value of 6.5 for the NoSAS score was determined for predicting difficult mask ventilation.
  • A cut-off value of 7.5 for the NoSAS score was determined for predicting difficult intubation.
  • The NoSAS score is designed to be an easy-to-use and rapid tool for identifying obstructive sleep apnea syndrome (OSAS).
  • Routine use of the NoSAS score may improve preoperative assessment of airway difficulty in patients undergoing general anesthesia.
