- The intubation time in the high-flow nasal oxygenation (HFNO) group was significantly shorter than in the standard mask oxygenation (SMO) group (69 seconds versus 76 seconds)
- There was a lower use of rescue face-mask ventilation in the HFNO group than in the SMO group (4% versus 27%)
- The desaturation rates (SpO2) were lower in the HFNO group during tracheal intubation (94% versus 91%)
- There was no significant difference regarding the incidence of mortality at 7 days
This data comes from a prospective randomised controlled study of 58 patients. It compares the efficacy and the safety of the use if a high-flow nasal oxygenation (HFNO) during fibreoptic bronchoscopic intubation versus a standard mask oxygenation (SMO) in patients suffering from COVID-19 pneumonia that require intubation in ICU setting. Among the patients, 28 were in the group HNFO and 30 were in the group SMO.
