Tracheal intubation is a widely used emergency measure in clinical medicine, especially in the process of cardiopulmonary resuscitation and rescue of respiratory disorders, which plays a crucial role. As an anesthesiologist, one must have a solid and proficient grasp of the skills. The following will provide a detailed introduction to the relevant popular science knowledge of tracheal intubation.
1、 What is endotracheal intubation? Tracheal intubation is the insertion of a specially designed endotracheal tube through the mouth or nose, and then through the glottis. It is an important emergency measure that can keep the patient's airway unobstructed, provide ventilation and oxygen supply, perform respiratory suction, prevent aspiration, and provide the best conditions for cardiopulmonary resuscitation and respiratory distress rescue.
2、 The function of endotracheal intubation
1. Maintaining airway patency: When patients experience laryngeal edema, airway obstruction, and other conditions due to various reasons, timely endotracheal intubation can maintain airway patency and effectively prevent patients from dying due to suffocation.
2. Provide ventilation and oxygen supply: Tracheal intubation can be connected to a ventilator to provide ventilation and oxygen supply to patients, maintaining their normal respiratory function.
3. Respiratory tract suction: Tracheal intubation can promptly remove secretions from the patient's respiratory tract, effectively avoiding respiratory obstruction.
4. Prevention of aspiration: Tracheal intubation can effectively prevent aspiration caused by vomiting and other reasons, thereby reducing the incidence of complications such as aspiration pneumonia.
5. Provide optimal conditions: Tracheal intubation can provide the best conditions for cardiopulmonary resuscitation and respiratory distress rescue processes, helping doctors to provide better treatment.
3、 What situations require endotracheal intubation
Tracheal intubation is suitable for the following situations:
1. Severe respiratory failure: When a patient experiences severe respiratory failure for various reasons, timely endotracheal intubation can maintain the patient's normal respiratory function.
2. Cardiopulmonary resuscitation: During the process of cardiopulmonary resuscitation, tracheal intubation can provide ventilation and oxygen supply to the patient, improving the success rate of cardiopulmonary resuscitation.
3. Respiratory obstruction: When patients experience difficulty breathing due to laryngeal edema, airway obstruction, etc., timely tracheal intubation can maintain airway patency.
4. Inhalation pneumonia: When a patient accidentally inhales due to vomiting or other reasons, tracheal intubation can promptly clear respiratory secretions and effectively prevent the occurrence of complications such as inhalation pneumonia.
5. Other situations: In certain special circumstances, such as general anesthesia surgery, bronchoscopy, etc., tracheal intubation is also required.
4、 Indications and Contraindications for Tracheal Intubation
1. Indications: Mainly suitable for severe respiratory failure, cardiopulmonary resuscitation, respiratory obstruction, aspiration pneumonia, etc., to maintain airway patency and normal respiratory function in patients.
2. Contraindications: In some special cases, such as severe edema of the larynx, huge thyroid compression of the trachea, severe cervical deformities, etc., tracheal intubation may increase the risk and difficulty for patients, and should be operated with caution or seek the help of professional doctors.
5、 Precautions for tracheal intubation
1. Strictly grasp the indications and contraindications: Before performing tracheal intubation, doctors should strictly grasp the indications and contraindications, and evaluate and make decisions based on the patient's condition and physical condition.
2. Strictly follow aseptic operation: When performing endotracheal intubation, doctors should strictly follow the principle of aseptic operation to avoid the occurrence of complications such as cross infection.
3. Adequate lubrication of the catheter: Before inserting the catheter, the doctor should lubricate it thoroughly to reduce irritation and damage to the patient.
4. Gentle operation: When inserting the catheter, the doctor should operate gently to avoid causing damage and discomfort to the patient. At the same time, attention should be paid to observing the patient's reactions and changes in vital signs.
5. Timely cleaning of respiratory secretions: After endotracheal intubation, it is necessary to clean the patient's respiratory secretions in a timely manner to maintain airway patency and prevent infection.
6. Pay attention to airbag pressure: After inserting the catheter, pay attention to observing the airbag pressure and adjust it in a timely manner to ensure normal ventilation of the patient and prevent air leakage. At the same time, attention should be paid to observing the patient's breathing condition and changes in blood oxygen saturation.
6、 Health education content for tracheal intubation:
1. Psychological guidance: Provide appropriate psychological care to patients to reduce anxiety and unease.
2. Dietary guidance: Place a gastric tube and provide liquid diet through nasal feeding.
3. Rest and activity guidance: Keep the air in the ward fresh, open windows regularly for ventilation, and maintain appropriate indoor temperature and humidity. Regularly replace the fixed adhesive tape and take good oral care.
4. Explanation of intubation purpose and precautions: Explain to patients and their families the purpose and operation steps of endotracheal intubation, as well as the precautions that patients and their families need to pay attention to during the operation process. Introduce the necessity, operation methods and steps, possible complications and treatment methods of intubation, and alleviate the doubts and fears of patients and their families.
5. Encourage coughing and breathing: Explain to patients how to effectively cough and breathe, encourage them to cough up phlegm in a timely manner, maintain airway patency, and prevent the accumulation of respiratory secretions and lung infections.
6. Avoid intubation displacement: Explain to patients and their families how to avoid tracheal intubation displacement or detachment, maintain the correct position of the intubation, and promptly notify medical staff if any abnormalities are found.
7. Cooperate with treatment: Explain to patients how to cooperate with medical staff for treatment and care, including suction, oral care, turning over, etc., to improve patient comfort and treatment effectiveness.
8. Reasonable rest and activity: Guide patients to arrange rest and activity time according to their own situation and the advice of medical staff, and engage in appropriate bed activities and exercises to prevent deep vein thrombosis.
9. Nutritional support: Introduce the importance of nutritional support to patients, develop personalized dietary plans based on their nutritional needs and dietary preferences, and ensure adequate and balanced nutrient intake.
10. Prevention of infection: Introduce the importance of preventing infection to patients, guide them to pay attention to personal hygiene, maintain a clean environment, avoid contact with infection sources, and other measures to prevent hospital acquired infections.
