Introduction
Tracheal intubation, also called intubation, is a procedure in which a tube is inserted into the trachea (windpipe) to help a person breathe. The tube is usually connected to a ventilator (breathing machine) . Learn more about tracheal intubation.
Tracheal intubation is often performed by anesthesiologists, who are doctors who specialize in giving anesthesia and monitoring patients during surgery. Anesthesiologists follow strict guidelines and recommendations to ensure the safety and comfort of patients during tracheal intubation . Read the ASA practice guidelines for management of the difficult airway
Tracheal intubation can save lives, but it can also cause serious complications, such as bleeding, infection, injury, or difficulty breathing. However, these are rare and can be prevented or treated by experienced and skilled anesthesiologists.
According to a study published in the British Journal of Anaesthesia, the incidence of major complications associated with tracheal intubation in the UK was 0.133% . See the full study here.
Tracheal intubation can save lives, but it can also cause serious complications, such as infection, bleeding, or damage to the airway. Therefore, it is important to know the indications, contraindications, complications, and nursing care of tracheal intubation.
Indications of Tracheal Intubation
Tracheal intubation is indicated for patients who have difficulty breathing, who need mechanical ventilation, or who are at risk of aspiration. Some of the common conditions that require tracheal intubation are:
- Respiratory failure: This is when the lungs cannot provide enough oxygen to the body or remove enough carbon dioxide from the blood. This can be caused by various factors, such as lung diseases, chest injuries, neuromuscular disorders, or drug overdose.
- Airway obstruction: This is when the airway is blocked by foreign objects, swelling, tumors, or bleeding. This can prevent the patient from breathing normally and cause choking, coughing, or wheezing.
- Anesthesia: This is when the patient is given drugs to induce a state of unconsciousness, pain relief, or muscle relaxation. This can affect the patient’s ability to control their breathing and protect their airway from saliva, blood, or vomit.
There are different methods of tracheal intubation, such as oral, nasal, or surgical. The choice of method depends on several factors, such as the patient’s condition, anatomy, preference, and availability of equipment. Each method has its own advantages and disadvantages, such as ease of insertion, comfort, risk of infection, or damage to the tissues.
For example, oral intubation is the most common and preferred method, because it is easy to perform, allows for a larger tube size, and provides a better seal. However, it can also cause discomfort, dryness, or injury to the mouth, teeth, or vocal cords.
Nasal intubation is an alternative method, especially for patients who have facial trauma, clenched teeth, or limited mouth opening. However, it can also cause bleeding, infection, or sinusitis.
Surgical intubation is a last resort method, when the other methods are not possible or fail. It involves making an incision in the neck and inserting the tube directly into the trachea. However, it can also cause complications, such as bleeding, infection, or scarring.
The Importance of Tracheal Intubation
Ensuring Adequate Oxygenation and Ventilation
Adequate oxygenation and ventilation are paramount during tracheal intubation to ensure optimal patient outcomes.
This essential aspect of the procedure involves effectively delivering oxygen to the lungs and removing carbon dioxide, maintaining vital gas exchange.
Let’s discuss why ensuring adequate oxygenation and ventilation is crucial and the strategies employed to achieve this goal.
Importance of Oxygenation
During tracheal intubation, oxygenation plays a vital role in maintaining tissue perfusion and preventing hypoxemia. Hypoxemia, characterized by low blood oxygen levels, can have severe consequences, including organ dysfunction and even cardiac arrest.
By ensuring adequate oxygenation, healthcare professionals can safeguard the patient’s well-being throughout the intubation process.
Techniques for Oxygenation
To optimize oxygenation, several techniques can be employed during tracheal intubation:
a) Preoxygenation:
Before initiating the procedure, preoxygenation is crucial to maximize the patient’s oxygen stores. Administering high-flow oxygen through a face mask or using a bag-valve-mask (BVM) ventilation technique can achieve this. Preoxygenation helps extend the duration of safe apnea and minimizes the risk of hypoxemia during the intubation process.
b) Apneic Oxygenation:
Apneic oxygenation is a technique that delivers oxygen continuously during periods of apnea. By using a nasal cannula or a specialized apneic oxygenation device, such as high-flow nasal cannula (HFNC) or nasal oxygen catheters, oxygen is supplied to the patient’s airway, promoting adequate oxygenation during the intubation procedure.
c) Intermittent Positive Pressure Ventilation (IPPV):
During the intubation process, intermittent positive pressure ventilation can be utilized to provide oxygenation and ventilation support. By applying positive pressure to the lungs via bag-valve-mask ventilation or mechanical ventilation, oxygen is effectively delivered, ensuring adequate oxygenation while intubation is being performed.
Ventilation Considerations
Alongside oxygenation, proper ventilation is crucial to remove carbon dioxide and maintain normocapnia. Inadequate ventilation can lead to hypercapnia, which can have detrimental effects on patient physiology. Optimal ventilation strategies should be employed during tracheal intubation to ensure efficient gas exchange.
a) Proper Bag-Valve-Mask Technique:
When utilizing bag-valve-mask ventilation, attention to technique is vital. Ensuring a proper mask seal and utilizing appropriate ventilation pressures can optimize ventilation effectiveness. Healthcare providers must be cautious to avoid excessive ventilation pressures, which can lead to complications such as gastric insufflation or barotrauma.
b) End-Tidal Carbon Dioxide (EtCO2) Monitoring:
Continuous monitoring of EtCO2 levels is essential during tracheal intubation. EtCO2 provides valuable feedback on the effectiveness of ventilation and confirms proper endotracheal tube placement. Monitoring EtCO2 levels helps identify potential complications such as esophageal intubation or mainstem bronchus intubation promptly.
Ensuring adequate oxygenation and ventilation during tracheal intubation is crucial to maintain optimal patient safety and outcomes. Preoxygenation, apneic oxygenation, and appropriate ventilation techniques such as bag-valve-mask ventilation contribute to efficient oxygen delivery and carbon dioxide removal.
By implementing these strategies and closely monitoring gas exchange parameters, healthcare professionals can minimize the risks associated with hypoxemia and hypercapnia, providing the best possible care to their patients during tracheal intubation.
Preventing Aspiration and Complications
Preventing aspiration and complications is a critical aspect of tracheal intubation to ensure patient safety and minimize potential risks. Aspiration occurs when gastric contents or other substances enter the airway, leading to severe complications such as pneumonia, respiratory distress, or even aspiration pneumonitis.
Implementing preventive measures and adopting best practices during tracheal intubation can significantly reduce the occurrence of aspiration and associated complications.
Here are the strategies employed to prevent aspiration and complications during this procedure.
Patient Preparation
Proper patient preparation is essential to minimize the risk of aspiration. This includes:

b) Preoperative Assessment:
Conducting a comprehensive preoperative assessment is crucial to identify patients with an increased risk of aspiration. Factors such as obesity, gastroesophageal reflux disease (GERD), pregnancy, or a history of hiatal hernia should be carefully considered.
Positioning
Appropriate positioning during tracheal intubation is vital to prevent aspiration. The following considerations should be taken into account:
a) Head-Elevated Position:
Raising the patient’s head to a semi-upright position, preferably at a 30-degree angle, helps minimize the risk of regurgitation and aspiration during the procedure.
b) Neck Flexion and Chin Lift:
Properly positioning the patient’s head with neck flexion and chin lift assists in achieving optimal visualization of the airway and facilitates the passage of the endotracheal tube.
Rapid Sequence Induction (RSI)
Rapid sequence induction is a technique utilized during tracheal intubation to minimize the risk of aspiration. It involves the administration of an induction agent, followed by a neuromuscular blocking agent, to facilitate intubation. RSI helps secure the airway swiftly while reducing the chances of regurgitation and subsequent aspiration.
Cricoid Pressure
Applying cricoid pressure, also known as Sellick’s maneuver, is a technique employed to reduce the risk of aspiration during intubation. This maneuver involves the application of pressure on the cricoid cartilage, compressing the esophagus and preventing the passive regurgitation of gastric contents into the airway.
Rapid Intubation Techniques
Employing techniques that minimize the time required for tracheal intubation can further reduce the risk of aspiration. Utilizing video laryngoscopy or alternative intubation devices that offer improved visualization and facilitate a faster intubation process can be advantageous in this regard.
Confirmation of Tube Placement
Verifying the correct placement of the endotracheal tube after intubation is essential to prevent complications. Utilizing capnography, auscultation, and chest X-ray when necessary ensures accurate tube placement and minimizes the risk of complications associated with incorrect positioning.
By adhering to these preventive strategies and best practices, healthcare professionals can significantly reduce the incidence of aspiration and associated complications during tracheal intubation.
Ensuring appropriate patient preparation, employing proper positioning, implementing rapid sequence induction, applying cricoid pressure, utilizing rapid intubation techniques, and confirming tube placement contribute to a safer and more successful intubation procedure.
