9
Q

Nasal intubation should be considered when _(general condition)_. Give two (of three listed) examples).

A
  1. Oral intubation is not feasible;
  2. Swollen tongue (Glossitis; e.g., angioedema);
  3. Mechanical obstructions to mouth opening (e.g., mandibular fixation and trismus);

    * https://litfl.com/nasal-intubation/*

Note: “It is best in patients who are not critically hypoxic and in whom there is obvious oral pathology making intubation and ventilation through the mouth problematic.”

  1. Spray - Trumpet - Spray - Tube - Spray;

Q

Describe the seven general steps of the Berdan Method of Prehospital Blind Nasal Intubation.

A
  1. Sedate patient with Ketamine (2 mg/kg IV/IO or 4 mg/kg IM) and support oxygenation with BVM;
  2. Apply 2-3 sprays of Oxymetazoline into each naris;
  3. Lubricate two nasal trumpets with 2% lidocaine jelly, insert, remove from target naris after one minute;
  4. Place nasal cannula at 15 lpm in secondary naris (or mouth) for passive / apneic oxygenation;
  5. Lubricate tracheal tube with 2% lidocaine jelly (as large as will fit into the naris and be tolerated, generally at least 7.0 mm ID), attach BAAM whistle and insert (keeping the proximal end of the tube directed toward the patient’s contralateral nipple) until loud breath sounds are audible (approximately 15 cm);
  6. Pass tracheal tube through cords during inhalation, confirm placement and secure in place;
  7. Administer Rocuronium (1 mg/kg IV/IO);

15
Q

Generally speaking (although not allowed by written order through the PCPs), with regard to ___ intubation, “topicalization is essential not only for patient comfort, but also to ensure proper placement. Without proper topicalization, the patient will gag, cough, and swallow the tube, preventing it from going into the trachea.”

A
  1. Nasal;

25
Q

During BVM-assisted ventilation, rescuers must use caution to avoid generating high airway pressures. In general, inspiratory pressures greater than 1. _ cm H2O in the adult patient increases the risk of forcing air through the esophagus and into the stomach, a condition known as gastric insufflation.
