“HFNC During Awake Craniotomy - Impact on Patient Comfort”
Background: Patients undergoing awake brain surgery are exposed to non-humidified, non-warmed oxygen/air mix flow through a face mask for a prolonged duration. This causes increased discomfort, inadequate breathing with the risk for hypoxia perioperatively. Humidified high flow nasal cannula (HFNC) oxygen therapy potentially improves patient comfort, oxygen/air exchange, improves surgical conditions and prevents atelectasis of the lung, compared to traditional oxygen administration using a face mask in patients undergoing awake brain surgery. Results of this trial will be used to initiate a more extensive, multicenter trial to further characterize the potential impact of HFNC.
Device - HFNC
High flow nasal humidified oxygen HFNC is an air-oxygen blender, which provides high flow (up to 60 L/min) of warmed (36Â°C) and humidified gas through nasal cannula, allowing tighter control of FiO2 from 0.2 to 1.0.
Device - Oxygen Mask
Application of oxygen during conscious sedation
