简要总结
Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) using high flow oxygen therapy for preoxygenation and oxygen supplementation during apnoea has shown promising results
详细描述
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%.

研究组 & 干预措施
face mask group
Pregnant females will be preoxygenated with 100% oxygen using a tight-fitting face mask at a rate of 6 L/min for 3 min with end-tidal gas monitoring.
干预措施: F Group (Other)
THRIVE group
High-flow humidified oxygen warmed to 37°C will be delivered through nasal cannula at the rate of 30 L/ min for 30 seconds then 50 liters per minute for a further 150 seconds.
干预措施: H Group (Other)
结局指标
主要结局
measure the time of safe apnea
时间窗: 10 minutes after induction
The apnea time will start from the onset of cessation of breathing as evidenced by a flat line in the capnogram with the absence of chest movements
