Tracheostomy and Tracheostomy Care
Margaret Mary Kuczkowski
Gregory J. Milmoe
Infants with airway obstruction or need for prolonged ventilatory support are often considered for tracheostomy as an alternative to endotracheal intubation. The timing and sequelae have long been debated (1, 2, 3, 4, 5). Emphasis on ongoing care aims to improve management and safety (3). Early involvement of the family helps to allay fears, and promote safety for home care.
A. Indications
1. Prolonged ventilator support—for pulmonary, neurologic, or neuromuscular reasons
2. Congenital airway anomalies, craniofacial or laryngotracheal
3. Acquired subglottic or tracheal stenosis
B. Contraindications
1. Unstable physiology
a. Sepsis
b. Pneumonia not yet controlled
c. Pulmonary instability requiring high inspiratory pressures or need for high-frequency ventilation
d. Cardiovascular instability—shunting, arrhythmia, or hypotension
e. Evolving neurologic or renal injuries
2. Distal obstruction not relieved by tracheostomy—mediastinal mass or severe stenosis at carina
C. Precautions
1. Patient should be stable but this is always relative
2. This procedure should be done only in facilities where there is appropriate support for postoperative management
3. Anticipate anomalies that make trachea relatively inaccessible
a. Massive cervical hemangioma—bleeding issues
b. Massive cervical lymphangioma—severe distortion of neck anatomy
c. Massive goiter—might be manageable medically
d. Chest syndromes with severe kyphoscoliosis or tracheal distortion
4. Anticipate need for increased pulmonary support afterward to counter atelectasis and increased secretions immediately postop. Tracheostomy tubes allow for air leak through the stoma and larynx (even with cuff). In contrast, an endotracheal tube fits more snugly at the cricoids, creating a more closed system for ventilation.
5. Neonates are less able to tolerate bacteremia. Use perioperative antibiotic to cover skin flora.
6. If the patient is not currently intubated, have endoscopy equipment available and discuss intubation options with the anesthesiologist.
7. The infant larynx differs from that of the adult and older child (Fig. 40.1)
a. More pliable and mobile
b. Relatively higher in the neck
c. Thymus and innominate artery can override the trachea in the surgical field
D. Procedure
1. Obtain informed consent and perform “time-out” procedure as per institutional guidelines (see Chapter 3).
2. Equipment check done for instruments, sutures, endoscopy backup and available trach tubes. Tubes are selected based on needed caliber and length.
3. Anesthesia team will apply monitors, check IV line, and confirm satisfactory ventilation through the endotracheal tube before administering anesthetic agents.
4. Remove nasogastric tube to avoid confusion when palpating the trachea. Do not place an esophageal stethoscope.

5. Position patient with neck extended, using shoulder roll. Prep the surgical site from above the chin to below the clavicles. Then drape the patient, allowing the anesthesiologist access to the endotracheal tube and the securing tape.
6. Inject the skin and deeper tissues with local anesthetic (0.5 to 1 mL of 1% lidocaine with 1:100,000 epinephrine).
7. Identify the following landmarks: Suprasternal notch, chin, midline, trachea, and cricoid. In small neonates the cricoid may be difficult to palpate.
8. Make the skin incision vertically in the midline. This allows easier retraction and avoids excessive lateral dissection.
9. Dissect in the midline down to the tracheal wall, identifying strap muscles, thyroid gland, trachea, thyroid cartilage, and cricoid ring.
10. Place Senn or Ragnell retractors on either side of the trachea for optimal visibility. If the thyroid gland cannot be displaced by blunt dissection, then divide the isthmus and ligate with silk sutures.
11. Place vertical stay sutures on either side of the planned tracheal incision (usually the third and fourth rings). These sutures are the infant’s lifeline should the tube become dislodged or need urgent replacement in the first week before the wound matures (Fig. 40.2).
12. Incise the trachea vertically for two or three rings depending on the size of the tube needed. The anesthesiologist will loosen the tape and withdraw the endotracheal tube until the tip is just visible (Fig. 40.3). The tracheostomy tube is then placed in the airway.

13. Ventilation is then confirmed by end-tidal carbon dioxide measure and oxygen saturation, as well as auscultation of both lung fields.
14. Secure the tube with twill tape or Velcro ties. Either way, only one finger should fit between the tape and the neck when the baby’s neck is in neutral position. At most centers the flange itself will be sutured to the neck until the first tube change.
15. Secure the tracheal stay sutures to the neck with tape labeled as to the correct side (Fig. 40.4).
16. Transport the patient back to the intensive care unit with a backup endotracheal tube and laryngoscope available. Upon arrival obtain chest radiograph to check tube position and lung status. If needed, replace NG tube before x-ray.
E. Immediate Postoperative Care (Day 0 Until First Trach Change)
Note: The first tracheostomy tube change is to be performed by the surgical team and the timing is at the discretion of
the surgeon (varies between postop days 3 and 7, majority between days 5 and 7) (4).

1. Provide bedside nursing and respiratory therapy care in intensive care setting with nurses and therapists who are trained and competent in the care of infants with upper airway disorders and tracheostomies. These nurses and respiratory therapists need to be skilled in respiratory assessment, routine tracheostomy management, and can anticipate and manage tracheostomy emergencies (6).
2. Keep spare tracheostomy tubes at bedside at all times (one of the same size and one size smaller) (4, 6, 7, 8).
3. Airway information sheet at bedside needs to include: Tracheostomy brand and tube size, suction catheter size, suction depth including any adapter (Fig. 40.5) (7, 8).
4. Airway management
a. Humidification: Provide adequate humidification via assisted ventilation or heated humidification tracheostomy collar.
(1) Rationale: Normally the nasal airway warms and humidifies air that enters the body; however, a tracheostomy bypasses the nasal airway allowing less humidified air to enter. Air that is not humidified can thicken secretions and increase the risk of mucus plugging.
(2) Precaution: Condensation from the water vapor can collect on the tubing walls and in the tubing and can be a potential source of bacterial growth (7).
b. Ventilation: Wean ventilator setting with a goal of tracheostomy collar unless patient is chemically paralyzed (see Chapter 7)
(1) Keep head of bed (HOB) elevated 20 to 30 degrees (4).
(2) Precaution: Correct tracheostomy tube placement is essential. Continually monitor respiratory status, including vital signs and clinical appearance of adequate oxygenation and ventilation. Infants can exhibit diminished breath sounds, changes in color, increased peak pressures, increased work of breathing, and change in mental status and increase in agitation if the tube becomes dislodged, blocked, or misplaced (8).
c. Suctioning: Suction every 4 hours and as needed (4).
(1) Indication: Suctioning may be required if the patient exhibits increased work of breathing, respiratory distress, desaturation, increased restlessness, visible secretions, audible respirations, tachypnea (7).
(2) Precaution: Careful suctioning practices must be followed to avoid complications, including hypoxemia, bronchospasm, hypo- or hypertension, laryngospasm, atelectasis, decreased lung compliance, airway trauma, and increased intracranial pressure (4, 7).
