Study Notes
Introduction to ET Intubation
- ET intubation is a procedure in which an ET tube is placed inside the trachea through the mouth or nostrils.
- It is simpler than tracheotomy, a surgical procedure that creates an airway opening by cutting into the trachea.
- ET intubation is preferred as the initial means of establishing an artificial airway.
Indications for ET Intubation
- General indications: patient requires an artificial airway for a brief period (e.g., 10 days or less) and full recovery is expected.
- Relief of airway obstruction:
- Epiglottitis
- Facial burns and smoke inhalation
- Vocal cord edema
- Protection of the airway:
- Prevention of aspiration
- Absence of coordinated swallow
- Facilitation of suctioning:
- Excessive secretions
- Inadequate cough
- Support of ventilation:
- Ventilatory failure / respiratory arrest
- Chest trauma
- Postanesthesia recovery
- Hyperventilation to ↓ intracranial pressure
ET Tube Insertion
- An ET tube may be inserted orally (oral intubation) or nasally (nasal intubation) through the larynx into the trachea.
- Intubation through the mouth is the preferred method of establishing an artificial airway.
- Oral route provides quick access to the lungs in emergency situations and allows the passage of a larger ET tube than the nasal route.
Initial Intubation Procedure
- Prior to intubation, the patient must be assessed to rule out any potential contraindications.
- The degree of difficulty in intubation due to anatomical structures can be evaluated by using the Mallampati classification method:
- Class 1 (easiest)
- Class 2 (difficult)
- Class 3 (more difficult)
- Class 4 (most difficult)
Equipment Needed for ET Intubation
- Required equipment:
- Laryngoscope handle
- Blade
- ET tube
- 10-mL syringe
- Water-soluble lubricant
- Tape
- Stethoscope
- Optional supplies:
- Stylet
- Topical anesthetic
- Magill forceps
ETT Sizes Estimation
- Size refers to the internal diameter (ID) of the tube in millimeters (mm).
- ETT sizes for different age groups:
- Neonate (, 1000 grams): 2.5 mm ID
- Neonate (1000 to 2000 grams): 3.0 mm ID
- Neonate (2000 to 3000 grams): 3.5 mm ID
- Neonate (. 3000 grams): 4.0 mm ID
- Child (1 to 2 years): 4.5 mm ID
- Child (2 to 12 years): 4.5 + (age/4) mm ID
- Adult female: 7.0 or 7.5 mm ID
- Adult male: 7.5 or 8.0 mm ID
Length of ETT
- Length of ETT for different age groups:
- Neonates: 6 + weight (in cm)
- >2 years: age/2 + 12 (in cm)
- Adult:
- Male: 21-24 cm
- Female: 18-21 cm
Procedure for Oral Intubation
- Steps for oral intubation:
- Assemble and test supplies
- Lubricate the deflated cuff with a water-soluble lubricant
- Inform or explain the procedure to the patient
- Bag-mask ventilate and preoxygenate the patient with 100% oxygen
- Tilt the head back and place in the sniffing position
- Open the mouth, apply anesthetic spray
- Hold the laryngoscope handle and insert the blade into the right side of the opened mouth
- Slide the blade to the base of the tongue and sweep the blade to the left
- Maneuver the tip of the straight blade underneath the epiglottis
- Lift the handle and blade up anteriorly to displace the tongue and attached soft tissues
- Locate the epiglottis, larynx, and vocal cords
- Insert the ET tube through the vocal cords under direct vision
- Inflate the cuff and confirm endotracheal tube placement
- Verify proper depth of ET tube placement with a chest radiograph
Complications of ET Intubation
- Complications during intubation:
- Trauma to lip, tongue, or teeth
- Hypertension and tachycardia or arrhythmia
- Pulmonary aspiration
- Laryngospasm
- Bronchospasm
- Esophageal intubation
- Complications during remained intubation:
- Obstruction from kinking, secretion, or overinflation of the cuff
- Accidental extubation or endobronchial intubation
- Disconnection from the breathing circuit
- Pulmonary aspiration
- Complications during extubation:
- Laryngospasm
- Pulmonary aspiration
- Edema of the upper airway
- Complications after extubation:
- Sore throat
- Hoarseness
- Tracheal stenosis (Prolong intubation)
- Laryngeal granuloma
