Role of high flow nasal oxygen in the management of a case of anaesthesia related aspiration pneumonia

Regurgitation and pulmonary aspiration of gastric contents is a feared complication of anaesthesia resulting in serious sequelae including acute hypoxemic respiratory failure (AHRF). Early application of non-invasive positive pressure ventilation (NIV) decreases the rate of endotracheal intubation and ICU mortality in AHRF. However, NIV is often complicated by high airway pressures predisposing to mask leaks, discomfort and device intolerance [1]. Recently high-flow oxygen delivered through nasal cannula (HFNO) has emerged as an alternative to NIV.
