High-flow nasal cannula oxygenation in comparison with apnoeic oxygenation during foreign body removal by rigid bronchoscopy: A randomised controlled trial.

Background And Aims: This trial aimed to assess the safety and efficacy of oxygenation using a high-flow nasal cannula (HFNC) compared with the standard apnoeic oxygenation technique during foreign body (FB) removal by a rigid bronchoscope.

Methods: A prospective, blinded, randomised, controlled trial was conducted on subjects planned for FB removal by a rigid bronchoscope. Inclusion criteria were male and female patients aged between 10 and 40 years.
