Endotracheal intubation plays a crucial role in intensive care, serving as a vital means to maintain airway patency and ensure effective ventilation and oxygenation for critically ill patients. In the Intensive Care Unit (ICU), endotracheal intubation is often employed for patients requiring mechanical ventilation support, particularly in cases of acute respiratory failure, severe trauma, pneumonia, and anesthetic emergencies.

The primary function of endotracheal intubation is to ensure the airway remains unobstructed and to prevent airway obstruction or aspiration. In critically ill patients, loss of consciousness, respiratory muscle fatigue, or airway inflammation can severely impair their ability to breathe independently. In such situations, endotracheal intubation provides effective mechanical ventilation support. Through the endotracheal tube, the medical team can continuously monitor the patient’s ventilation status, adjust respiratory parameters, and ensure adequate oxygen supply.

When performing endotracheal intubation, adhering to standardized operational steps is essential. First, the physician must conduct a thorough assessment of the patient’s airway status, including examining the oral cavity, pharynx, and neck anatomy. Choosing the appropriate size and type of endotracheal tube is critical for successful intubation. Additionally, preoperative preparations such as oxygenation assessment, pharmacological pre-treatment (e.g., sedatives, muscle relaxants), and equipment readiness (e.g., endotracheal tubes, ventilators, monitoring devices) are indispensable.

During the intubation procedure, maintaining sterile technique is crucial to ensure the cleanliness of equipment and the environment. The anesthesiologist should keep the patient in an optimal position, usually supine, while properly extending the head and neck. During intubation, the physician should confirm the tube's placement through visual and tactile feedback to ensure it is positioned in the trachea rather than the esophagus. If necessary, auxiliary confirmation can be achieved using auscultation or gas exchange monitoring devices.

After intubation, it is important to promptly verify the tube's position and secure it to prevent dislodgment while setting up mechanical ventilation parameters. Regular checks of the patient’s airway patency and the tube’s security should be performed to prevent complications such as airway injury, infection, or aspiration.

In intensive care, endotracheal intubation is not only a critical life-sustaining measure but also vital for the overall recovery of patients. The medical team must employ standardized procedures and rigorous management to ensure the safety and efficacy of endotracheal intubation, providing optimal medical care for patients.
