Endotracheal Intubation: A Life-Saving Medical Procedure

Endotracheal Intubation: A Life-Saving Medical Procedure

What is an Endotracheal Tube?

ET tubes are typically between 7-13 mm in diameter and 20-30 cm in length. The tube is made of a soft, flexible material like polyvinyl chloride (PVC) and has an inflatable cuff at the distal end that acts as a seal in the trachea to prevent air from leaking out. Some key parts of an ET tube include an inflatable cuff, tube body, metal tip, pilot balloon, and connector tubing.

The Endotracheal Intubation Process

Endotracheal intubation is performed when a patient requires their airway to be secured and breathing to be mechanically supported during surgery or critical illness. The ET tube insertion process involves first preparing the patient with an anesthetic, such as propofol, and a paralytic medication like succinylcholine. Endotracheal Tube This induces unconsciousness and muscle relaxation to prevent coughing or gagging as the tube is placed.

The next step is visualization and examination of the airway using a laryngoscope inserted into the mouth. This tool uses a curved blade and light source to improve visibility and expose the vocal cords so the trachea opening can be identified. Once the trachea is visualized, the ET tube is inserted carefully through the vocal cords and advanced into the trachea. Its progress is monitored under direct vision or with adjunct devices like a fiberoptic laryngoscope.

When placed correctly, the tube cuff is inflated with air to provide a seal. Correct positioning is confirmed using techniques like observing chest rise with bag-valve mask ventilation, measuring the tube at the patient's mouth or measuring static lung compliance with mechanical ventilation. The tube is then secured to prevent accidental dislodgement and attached to a ventilator circuit.

Common Uses for Endotracheal Intubation

Endotracheal intubation is one of the most frequently performed medical procedures. The most common clinical uses for ET tube placement include:

- General anesthesia during surgery: Allows unconscious breathing control and access to the airway during operations when respiration needs to be controlled or airway access is required.

- Airway protection during procedures: Protects the airway during procedures requiring full muscle relaxation like biopsies, reductions, and procedures on/around the face, mouth or throat.

- Ventilatory support during illness/injury: Mechanical ventilation via an ET tube is essential for patients unable to breathe effectively due to conditions like drug overdoses, trauma, heart attacks, pneumonia, ARDS, respiratory failure, or neuromuscular disorders.

- Tracheostomy bypass: ET tubes are temporarily placed in emergencies or post-op before a tracheostomy is ready to use for long-term ventilation needs.

- Upper airway obstruction: Quickly restores breathing in patients with severe upper airway obstruction from swelling, bleeding, foreign body, trauma, or burn inhalation injuries.

Potential Complications of Endotracheal Intubation

While endotracheal intubation is usually straightforward, like any medical procedure some potential risks and complications can occur:

- Tracheal injury or laryngeal injury: Vocal cord damage, tracheal perforation or rupture that could lead to mediastinal emphysema or pneumothorax.

- Dental injury: Tooth damage from use of laryngoscope or biting down on tube during placement.

- Hypoxemia: Inadequate oxygenation during intubation attempts leading to hypoxia.

- Pneumonia: Pulmonary aspiration of gastric contents by retracted or dislocated tube or ventilator-associated pneumonia.

- Tube malposition: Partial or mainstem intubation rather than into trachea resulting in inadequate ventilation.

- Misplacement: Tube placement in esophagus rather than trachea.

- Airway trauma: Laryngospasm, laryngeal edema, or vocal cord damage due to trauma during intubation.

- Bleeding: Trauma during laryngoscopy leading to epistaxis, hematemesis, or hemoptysis.

- Aspiration: Tube aspiration into right mainstem bronchus causing lung collapse.

- Tube obstruction: Kinking, coiling, or accumulation of secretions blocking tube functioning.

With appropriate precautions and by skilled personnel, many of the risks can be minimized to reduce complications from endotracheal intubation. It remains an invaluable lifesaving procedure when proper ventilation is vital. With continued technology advancements, intubation safety will further improve over time.
