High Flow Nasal Cannula to Prevent Deoxygenation During Induction of General Anesthesia in Cesarean Section

Not Applicable

• Conditions: Hypoxic Brain Injury; Maternal Death

• Registration Number: NCT04438798
• Lead Sponsor: Alexandria University

Brief Summary

Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) using high flow oxygen therapy for preoxygenation and oxygen supplementation during apnoea has shown promising results

Detailed Description

Eeffective preoxygenation followed by apnoeic oxygenation enables anaesthesiologists to safely prolong the apnoea time which is the time (seconds) of apnea following preoxygenation and muscle relaxation before to peripheral oxygen saturations (SpO2) decreases by 2%.
