NCT03950934 | Completed

• 1 other identifier: PV5856
• Study Type: observational
• Target: 400
• Locations: 1 country
• Sites: 1

Brief Summary

Primary aim of this study is to identify independent factors associated with difficult videolaryngoscopic intubation in patients undergoing oral and maxillofacial (OMF) or ear, nose and throat (ENT) surgery. Furthermore, this study intends to assess the diagnostic value of preoperative flexible nasal videoendoscopy to predict difficult videolaryngoscopic intubation in these patients.

Conditions

Oral Surgery; Maxillofacial Surgery

Keywords

Anesthesia; Airway Management; Intubation; Bronchoscopes; Risk Assessment; Surgery
