摘　　要：全身麻醉患者在行气管插管术时会经历不同时长的无通气情况,预氧合是进行气管插管的必要程序之一,旨在通过提升功能残气量的氧含量达到增加氧储备的目的,保证插管窒息时血氧饱和度稳定。选择个体化的预氧合方法将避免肺不张、胃胀气等潜在并发症,提高无通气期间的安全性。由于接受全身麻醉患者可能会在麻醉诱导后出现困难面罩通气和困难气管插管的情况,因此所有患者都需要预氧合,以降低麻醉诱导期及气管插管带来的风险。本文对近年来全身麻醉诱导期间预氧合的研究进展进行综述,为临床医护人员采取全身麻醉诱导期间的预氧合提供参考。Patients under general anesthesia may experience different periods of non-ventilation during endotracheal intubation.Preoxygenation is one of the necessary procedures to perform endotracheal intubation,aiming at increasing oxygen reserve by increasing oxygen content of functional residual volume and ensuring stable blood oxygen saturation during intubation asphyxia.The choice of an individualized preoxygenation method will avoid potential complications such as pulmonary atelectasis and gastric distention,and improve safety during periods of non-ventilation.Due to the possibility of difficult mask ventilation and difficult endotracheal intubation in patients undergoing general anesthesia induction,all patients require preoxygenation to reduce the risks associated with anesthesia induction and endotracheal intubation.In this paper,the research progress of preoxygenation during induction of general anesthesia in recent years was reviewed,which can provide references for clinical medical staff to adopt preoxygenation during induction of general anesthesia.
