Sonographic Evaluation to Predict Difficult Airway Management

NCT03991325 | Completed

• 1 other identifier: sonographic evaluation airway
• Study Type: observational
• Target: 200
• Locations: 1 country
• Sites: 1

Brief Summary

the aim of this study was to evaluate the accuracy of different ultrasonographic parameters and clinical tests to predict difficult airway assessment. Ultrasonographic parameters were: hyo-mental distence, tongue width, skin to epiglottis distence and skin to hyoid bone distence. these parameters were recorded and their predictive acurracy was studied.

Conditions

Airway Management; Upper Airway Sonographic Evaluation

Outcome Measures

Primary Outcomes (1)

• prediction of difficult laryngoscopy with ultrasonographic criteria

  incidence of difficult laryngoscopy

  5 min after induction of general anesthesia determined by Cormack and Lehane grade

Secondary Outcomes (1)

• prediction of difficult mask ventilation with ultrasonographic criteria

  3 min after induction of general anesthesia

Study Arms (2)

difficult laryngoscopy

group of patients with Cormack and Lehane grade III or IV

Diagnostic Test: upper airway sonography
