Indications for a tracheotomy are numerous but include securing the airway in anticipation of or actual airway obstruction, for example edema, Ludwig angina, or retropharyngeal abscess. Tracheostomy can be part of a scheduled procedure, such as a laryngectomy. If prolonged intubation is anticipated, such as critically ill patients in an ICU setting, tracheotomy is indicated to protect the larynx from injury. In addition, tracheotomy should be performed when convenient following emergent cricothyrotomy to reduce the incidence of subglottic stenosis and cricoid chondritis. Rarer indications for tracheotomy include bilateral vocal cord paralysis or a history of recurrent allergy associated with laryngospasm.

In a tracheostomy, a short transverse incision or midline vertical incision is made 1-2 cm inferior to the cricoid. The tracheostomy tube is sutured to the skin.

Preoperative management

Patient evaluation

System	Considerations
Airway
Neurologic
Cardiovascular	All patients possibly with significant cardiac risk factors, related to smoking, EtOH abuse, male gender, HLD, HTN.
Pulmonary	Thorough airway exam, particularly for patients for who a tracheostomy is part of a scheduled procedure. Assess for possible recurrent aspiration.
Gastrointestinal
Hematologic	If malignancy or chronic disease, coagulopathies or anemia may be present
Renal	Assess for renal disease if chronic illness
Endocrine	Consider adrenal suppression, hyperglycemia if ICU patient
Other	Note nutritional status

Labs and studies

• Head and Neck CT/MRI
• CXR, ABG as indicated from H&P

Patient preparation and premedication

• Standard premedication if elective
  • Avoid if critically ill of symptoms upper airway obstruction

Intraoperative management

Monitoring and access

• Standard monitors
  • Invasive monitors depending on condition
• Avoid ECG pads in the prepped area

Induction and airway management

Intubated	Convert ICU sedation to GA with propofol/remifentanil or inhalational agent
Not intubated with plan for GETA	Standard IV induction Consider awake FOI if airway problems anticipated
Awake Tracheostomy	Precedex

Positioning

• Supine, head extended with shoulder roll
  • Note ETT cuff can migrate cephaled - risk of inadvertent perforation by surgeon; tape securely

Maintenance and surgical considerations

General	Consider TIVA with propofol/remifentanil Muscle relaxation required, may use rocuronium Normovolemia, normothermia PONV prophylaxis with dexamethasone, ondansetron To avoid ETT cuff puncture, may advance closer to carina before trachea opened Slowly remove ETT under visualization of surgeon however do not remove completely Once tracheostomy tube secured, connect to circuit/suction Remove ETT once EtCO2 tracing confirmed and inflation pressures within normal limits
Awake

Postoperative management

Disposition

• Obtain CXR to assess tracheostomy tube position and check for evidence of pneumothorax / pneumomediastinum

Critically ill patients	Continue on ventilatory support in the ICU Careful suctioning, humidified oxygen Opioid sedation will minimize reaction to suctioning in early postoperative period Do not remove for 5-7 days until track formed
Awake or as part of scheduled procedure

Pain management

• Multimodal approach combining nonopioid (acetaminophen, NSAIDs), bolus/PCA opioids, peripheral local anesthetics

Potential complications

• Bleeding although EBL generally minimal
• Cellulitis / tracheitis
• Tracheal stenosis
• Pneumothorax
  • Seen if low neck dissection of false passage formation
• Pneumomediastinum
• Creation of false passage during procedure
  • Particularly true if increased mucosal swelling (edema, prolonged intubation) or increased tissue fragility (chronic steroid therapy)
  • Signs include absent end tidal, increased PIP
  • If suspect, should attempt to reintroduce existing ETT

• Occlusion of tracheostomy tube
  • Secretions, mucus plug, blood, mainstem

• Tracheostomy tube displacement
  • Re-intubate orally or through trach site
