Endotracheal intubation (hereinafter referred to as intubation) refers to the placement of a special endotracheal tube into the trachea through the glottis to open the patient's airway and provide optimal conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. Intubation is an important technique in the rescue process of critically ill patients, and it is also the basic operation for the implementation of inhalation anesthesia.
The main functions of endotracheal intubation:
Keep the airway open: Prevent aspiration of oral secretions and stomach contents.
Ventilation and oxygen supply: good oxygen supply and assisted ventilation help the body's tissue oxygen supply, which can effectively prevent complications and provide timely first aid in case of intraoperative emergency.
Control the depth of anesthesia: Compared with injection anesthesia and mask inhalation anesthesia, transtracheal intubation can effectively control ventilation to control the depth of anesthesia, and at the same time, intubation can prevent the escape of anesthetic gas to the surrounding environment and protect the surgical staff from inhaling more anesthetics. Reduces the waste of anesthetic gas and is more economical.
