Tracheal tube
Tracheal Tube[edit | edit source]
A tracheal tube is a medical device used to maintain an open airway or to administer certain drugs. It is inserted into the trachea either through the mouth (orotracheal) or the nose (nasotracheal) and is commonly used in anesthesia, intensive care medicine, and emergency medicine.
Types of Tracheal Tubes[edit | edit source]
There are several types of tracheal tubes, each designed for specific purposes:
- Endotracheal Tube: The most common type, used for general anesthesia and mechanical ventilation.
- Double-lumen Tube: Used for lung isolation in thoracic surgery.
- Reinforced Tube: Contains a wire coil to prevent kinking, used in head and neck surgeries.
- Cuffed Tube: Has an inflatable cuff to seal the trachea and prevent aspiration.
Indications for Use[edit | edit source]
Tracheal tubes are indicated in various clinical scenarios, including:
- Airway obstruction
- Respiratory failure
- General anesthesia
- Cardiopulmonary resuscitation
- Bronchoscopy
Procedure[edit | edit source]
The process of inserting a tracheal tube is known as intubation. It involves the following steps:
1. Preparation: Gather necessary equipment and ensure patient monitoring. 2. Positioning: Position the patient in the "sniffing" position to align the oral, pharyngeal, and laryngeal axes. 3. Preoxygenation: Administer 100% oxygen to the patient to increase oxygen reserves. 4. Laryngoscopy: Use a laryngoscope to visualize the vocal cords. 5. Insertion: Gently insert the tube through the vocal cords into the trachea. 6. Confirmation: Verify correct placement by auscultation, capnography, and chest X-ray.
Complications[edit | edit source]
Potential complications of tracheal tube use include:
History[edit | edit source]
