The precautions for disposable endotracheal intubation mainly include the following aspects:

Choose the appropriate size and type of catheter: Select the appropriate catheter based on the patient's glottis size, age, gender, and insertion path to avoid the catheter being too thin or too thick, which may affect the treatment effect.

Gentle operation: The texture of tracheal intubation is relatively hard, while the tracheal mucosa is relatively soft, so the intubation action should be gentle to prevent tracheal injury.

Accurate exposure and insertion: During tracheal intubation, appropriate methods (such as lifting the head and jaw) should be used to fully expose the trachea, ensuring that the catheter accurately enters the glottis and penetrates deeply.

Maintain patency and fixation: After intubation, the catheter should be properly secured and the tracheal intubation should be regularly checked for patency to ensure oxygen supply.

Pay attention to the position of the catheter: It is recommended to use X-rays or other auxiliary tools for guidance to accurately determine the position of the endotracheal tube and avoid the catheter accidentally entering one side of the bronchus or esophagus.

Avoid injury: When fixing the catheter, it is necessary to maintain a good gap between the catheter and the trachea to prevent the trachea from being compressed and damaging the mucosa. At the same time, regular oral hygiene should be carried out to keep the mouth moist, and nebulized inhalation should be performed to promote the discharge of phlegm.

Observing the patient's condition: Family members and medical staff should closely monitor the patient's condition. If there are any abnormal symptoms, they should immediately seek the help of a professional doctor.

In addition, if the patient has dentures, they should be removed before tracheal intubation to prevent tooth loss or suffocation caused by falling into the airway.

Please note that tracheal intubation is a professional medical procedure that should be performed by experienced medical personnel in strict accordance with operating procedures and precautions. For non professionals, do not attempt to operate on your own to avoid accidents or worsening the condition.
