Brief summary

To compare the effect of HFNC with standard apneic oxygenation on patient oxygenation and airway protection during foreign body removal by rigid bronchoscope.

Detailed description

This study is a prospective, randomized controlled trial, at Ain Shams University hospitals, Cardiovascular surgery hospital (Thoracic surgery unit), Cairo, Egypt. We will include 64 patients planned for foreign body removal by rigid bronchoscope. All patients will be ASA І with recent FB aspiration in the last 72hrs either by history or documented by radiopaque shadow in chest X ray or CT scan. After achievement of anesthesia and full muscle relaxation ventilation started by open mask technique. Then the patients will be divided into two groups according to the oxygenation technique: Group (A) (32 patients) HFNC (Vapotherm) will be used during the bronchoscopy time flow rate 50 L/min with 100% humidified oxygen and the temperature adjusted to be 38℃ . Group (B) (32 patients) (control group) using the standard apneic oxygenation through the side port of rigid bronchoscope during the procedure
