Orotracheal Intubation Optional, AEMT
Course Objectives • Describe Sellick’s maneuver and the use of cricoid pressure during intubation. • Describe the necessary equipment needed to perform orotracheal intubation. • Describe the indications, advantages, disadvantages, and complications of orotracheal intubation. • Describe the visual landmarks for direct laryngoscopy.
Course Objectives • Describe steps to perform orotracheal intubation. • Describe the methods of assessing, confirming, and securing correct placement of an orotracheal tube. • Describe the technique for extubation.
Sellick’s Maneuver • Helps prevent regurgitation and reduces gastric distention. • Locate the cricoid cartilage by palpating the thyroid cartilage and the feel the depression just below it (cricothyroid membrane). • Using your thumb and index finger of one hand, apply pressure to the anterior and lateral aspects of the cricoid cartilage just next to the midline. • See picture on next slide.
Airway with Sellick’s Applied (Note compression on the esophagus.)
Oraltracheal Intubation Equipment • Laryngoscope handle and blade • Endotracheal tube • 10 ml syringe • Stylet • BVM • Suction device • Bite block • Magill forceps • Tape or tube-holding device
Endotracheal Tube • 5.0 mm-9.0 mm (cuffed) • Distal end has a beveled tip for smooth movement through airway passages. • Length ranges from 12cm-32cm. • Typical size for an average adult male is 7.5-8.5 mm • Typical size for an average adult female is 7.0-8.0 mm
Oraltracheal Intubation Indicators • Respiratory or cardiac arrest • Unconsciousness • Risk of aspiration • Obstruction due to foreign bodies, trauma, burns, or anaphylaxis • Respiratory extremis due to disease • Pneumothorax, hemothorax, hemopneumothorax with respiratory difficulty
Advantages of Oraltracheal Intubation • Isolates trachea and permitscomplete control of airway • Impedes gastric distention • Eliminates need to maintain a mask seal • Offers direct route for suctioning • Permits administration of some medications
Disadvantages of Endotracheal Intubation • Requires considerable training and experience • Requires specialized equipment • Requires direct visualization of vocal cords • Bypasses upper airway’s functionsof warming, filtering, and humidifying the inhaled air
Complications of Oraltracheal Intubation • Equipment malfunction • Teeth breakage and soft tissue lacerations • Hypoxia • Esophageal intubation • Endobronchial intubation • Tension pneumothorax
Field Extubation • Prepare intubation equipment and suction • Confirm patient responsiveness • Suction the patient’s oropharynx • Deflate the cuff • Remove the tube upon cough or expiration • Provide supplemental oxygen as needed • Reassess the adequacy of the patient’s ventilation and oxygenation
Summary • Sellick’s manuever • Necessary equipment to perform orotracheal intubation • Indications, advantages, disadvantages, and complications of orotracheal intubation • Visual landmarks • Steps to perform orotracheal intubation • Methods of assessing, confirming, and securing correct placement of an orotracheal tube • Technique for extubation
