Safe Time for Apnea After Preoxygenation — STAP  

Anesthesia, General Clinical Trial

Official title:
Safe Time for Apnea After Preoxygenation With Different Oxygen Concentration During the Induction of General Anesthesia

Clinical Trial Summary

The use of 100% oxygen during the induction of general anesthesia is always preferable to have enough time to secure the airway by endotracheal intubation, because preoxygenation with a low oxygen concentration may reduce the safe time for apnea. However, using a low oxygen concentration during preoxygenation might prevent the formation of atelectasis. There is still no clear conclusion about the best oxygen concentration for preoxygenation. Our study is designed to evaluate the safety of preoxygenation with 80%, 60%, 40%, 30% and 21% oxygen by the safe time for apnea during the induction of general anesthesia.

Clinical Trial Description

We decide to add 3 groups (80%, 60%, and 40% oxygen) in our study to fully evaluate the safety of preoxygenation with different oxygen concentration. Zijia Li 2018.3.2 ;
